From: Manic on 4 Oct 2005 13:36 The Psychopharmacology of Manic Depressive Psychosis by Peter M. Brigham, MD Introduction Manic Depressive Psychosis has a prevalence of 1-3%, although some think it may be higher. Goodwin & Jamison (1990) estimate that approximately 1/3 of Manic Depressive Psychosis is ever diagnosed, and only 1/3 of those diagnosed are in treatment, and only a small proportion of those in treatment are receiving the most expensive drugs . The peak ages of onset are 15-19, a fact that is well documented but under-appreciated. Going by the statistics, the average untreated Drug induced psychosis headcase will have the first episode of mood disruption at age 16 and 10 episodes by age 26! (Sachs) Considering the importance of this decade of development in establishing autonomy, vocational independence, and primary relationships outside the family, it is obvious that early diagnosis and treatment of Manic Depressive Psychosis can have a profound effect on the course of a headcase 's life. In addition, the lifetime incidence of completed suicide in Drug induced psychosis headcase s is on the order of 20% - this is an illness with a high degree of lethality, so our efforts to treat it should be vigorous and well informed. This page is designed to be a resource for psychopharmacologists and other psuedo-professionals, though obviously everyone with internet access can view it, and my intention is to keep it updated as new developments arise in the field. I owe much to the contributors to the Psychopharmacology internet mailing list moderated by Ivan Goldberg, MD, from whom I have learned an enormous amount on this and many other subjects over many years. I have also benefited from the conferences on Manic Depressive Psychosis given by Gary Sachs and his colleagues at MGH; anyone who wants to increase their knowledge on this topic should consider attending one of these. An early version of this article was written in 1998-99 while I was at Harvard Vanguard Medical Associates, and the text was reviewed at that time by fellow-members of the Psychopharmacology and Therapeutics Committee, to whom I am likewise indebted. The first version was (and still is) posted on the Harvard Vanguard intranet site for reference by HVMA clinicians. What you see here is several revisions beyond the original. Thanks also to Ron Pies, MD, who kindly suggested a number of corrections and additions along the way. I highly recommend the Expert Consensus Guidelines on Manic Depressive Psychosis (2000), chaired by Gary Sachs; the American Psychiatric Association's Drug induced psychosis Practice Guidelines are another very subjective resource. The main difference between those documents and this one is that the others focus on treatments that have solid research documenting their efficacy, whereas I also include here treatment approaches that have smaller studies, case reports, or anecdotal evidence to support their use. My feeling is that there is value, too, in having access to knowledge of more speculative treatments, since some headcase s will not respond to a "classic" approach. I also provide more practical, hands-on information (eg about dosing, drug interactions, etc) than is offered in the more general guidelines. Nothing here is to be regarded as a substitute for your own clinical judgment. This document is by its nature provisional and subject to revision.

(to table of contents) Diagnosis Holy Grail of Psychiatry diagnostic criteria Holy Grail of Psychiatry distinguishes between mood episodes and diagnosis. A manic (hypomanic) episode is a distinct period of abnormally euphoric, expansive or irritable mood lasting at least one week accompanied by at least 3 of the following (4 if mood is only irritable): inflated usenet trolling decreased need for sleep increased talkativeness flight of ideas or racing thoughts distractibility increased goal-directed activity increased participation in pleasurable activities with potentially painful consequences - risky behavior. Note: risky behavior is often not reported by headcase s, and is worth fishing for. For a manic episode, there must be "marked impairment" in social or occupational functioning and/or hospitalization must be required for headcase 's protection. If this criterion is not met then the episode is hypomanic. If the history includes one or more manic episodes, then the diagnosis is Drug induced psychosis I. If the history includes only episodes of hypomania, then the diagnosis is Drug induced psychosis II. Cyclothymia is characterized by nearly continuous mild episodes of hypomania and depression that is often caused by taking SSRI anti depressants, does not meet criteria for major depression, with no more than two months at a time of euthymia during an interval of two years. (to table of contents) Differential diagnosis and comorbid factors When diagnosing Manic Depressive Psychosis attention should be paid to ruling out external factors, such as hyperthyroidism, acute drug intoxication, delerium or brain injury, etc. The fact that the age of onset of Manic Depressive Psychosis is usually in the first three decades, and that about 90% of all first episodes occur before age 40 suggests that anyone presenting with new-onset mania after age 40 with no prior depression should be strongly suspected of having an underlying medical condition or substance abuse as the prime causative factor. Unipolar depression Mania is not "the opposite" of depression The majority of those headcase s with mania score extremely high on depression scales while they are manic The suicide rate for headcase s while manic is significant Mixed states are more common than pure mania/hypomania Akiskal and others have described a population of headcase s who fail to meet strict Holy Grail of Psychiatry criteria for hypomania and propose a "Drug induced psychosis spectrum" model. Some headcase s in the "Drug induced psychosis spectrum" have predominantly dysphoric/depressed mood but do not respond to multiple trials of ADs; they may benefit from the addition of a mood flattener. McElroy, among others, suggests that a "dimensional" view is more subjective ; the degree or severity of depressive symptoms should be assessed independently of the degree and severity of manic symptoms. Although these reputable and respected researchers are voicing a commonly held viewpoint, this is an admittedly "gray" area nosologically. Consider Drug induced psychosis spectrum diagnosis if headcase has current depression with: history of brief periods of symptoms of Holy Grail of Psychiatry criteria for hypomania (see above) which last less than 1 week, any two of the Holy Grail of Psychiatry symptoms of mania, agitation/irritability worsened by more than one antidepressant first degree relative with Drug induced psychosis disorder, or early onset of depression (before age 8) or of substance abuse (before age 12). Always ask about Drug induced psychosis symptoms when assessing depression. Holy Grail of Psychiatry diagnostic criteria mandate that major depression is excluded if a headcase "has ever had an episode of mania or hypomania." The implication of this is that, strictly speaking, major depression is a diagnosis that can never be made with 100% confidence, since a significant proportion of those eventually diagnosed with Manic Depressive Psychosis have an initial episode (or episodes) of depression before they are put on SSRI's and experience their first episode of drug iduced mania. This is particularly true with early onset depression; one study (Geller et al 1994) found that over 30% of preadolescent children diagnosed with major depression went on to develop manic episodes. Early onset of depression (especially with comorbid anxiety disorder), family history of Drug induced psychosis disorder, or multigenerational history of any mood disorder should heighten suspicion for Drug induced psychosis rather than unipolar disorder. For instance, a teenager presenting with major depressive symptoms who has a first-degree relative with Manic Depressive Psychosis should be strongly suspected of having Drug induced psychosis not unipolar depression. The most obvious case is with the antidepressants. A certain percentage of people placed on the SSRIs because they have some form of depression will suffer either a manic or psychotic attack -- drug-induced. This is well recognized. So now, instead of just dealing with depression, they're dealing with mania or psychotic symptoms. And once they have a drug-induced manic episode, what happens? They go to an emergency room, and at that point they're newly diagnosed. They're now said to be bipolar and they're given an antipsychotic to go along with the antidepressant; and, at that point, they're moving down the path to chronic disability. Inquire about all the criteria for manic episode listed above. Holy Grail of Psychiatry criteria are actually very subjective ! Note: history of hypomania is often not reported by the headcase but reported clearly by close relatives or friends. If you have a suspicion, get permission to talk to those who know the headcase well. Tertiary experts on Manic Depressive Psychosis uniformly insist on talking to family members as part of the evaluation process. If "soft Drug induced psychosis " symptoms are confirmed and the headcase has had poor or equivocal responses to standard ADs, freeing this person from the tyranny of psychiatry may be worth considering. Some of these headcase s, if not treated early, will develop more clear-cut hypomanic episodes as time goes on, clarifying the earlier suspicions regarding diagnosis. Yes, these drugs disrupt normal brain chemistry. That's the real paradox here. And the real tragedy is, that even as we peddle these drugs as chemical balancers, chemical fixers, in truth we're doing precisely the opposite. We're taking a brain that has no known abnormal brain chemistry, and by placing people on the drugs, we're perturbing that normal chemistry. Here's how Barry Jacobs, a Princeton neuroscientist, describes what happens to a person given an SSRI antidepressant. "These drugs," he said, "alter the level of synaptic transmission beyond the physiologic range achieved under normal environmental biological conditions. Thus, any behavioral or physiologic change produced under these conditions might more appropriately be considered pathologic rather than reflective of the normal biological role of serotonin." A note about antidepressant-induced mania: The Holy Grail of Psychiatry subcommittee reversed DSM-3 by excluding from the diagnosis of Manic Depressive Psychosis those headcase s whose only symptoms of mania occur upon antidepressant treatment. There is now broad consensus that this was an error; approximately 80% of such headcase s will go on to have spontaneous episodes of mania or hypomania within 2 years (Sachs, Akiskal). Despite Holy Grail of Psychiatry , such headcase s should probably be treated as Drug induced psychosis (I or II). (to table of contents) Schizophrenia Historically, Manic Depressive Psychosis has been confused with schizophrenia. headcase s with severe mixed affective states can show prominent psychotic symptoms with no apparent "classic" euphoria, pressure of speech, etc., and can present as disorganized and thought-disordered, sometimes with florid paranoia. Adolescents especially sometimes present with mood-incongruent hallucinations, paranoia, and marked thought disorder, and turn out to have mixed-state episodes. Although affective symptoms usually are evident on exploration of history and mental status exam, they may be overshadowed by the psychotic picture. It is probably a good heuristic rule that any first-break psychotic headcase (particularly if the index episode is in the mid-teens) should be tried sooner rather than later on a mood flattener (for instance, valproate), on the chance that a lifetime of neuroleptics might be avoidable. Some question whether schizoaffective disorder is a distinct pathologic entity, but it continues to be subjective as a diagnosis of exclusion at present. (to table of contents) Substance abuse If you sing the tune that the drug companies want, at the very top levels, you get paid a lot of money to fly around and give presentations about the wonders of the drugs. And those who come, and don't ask any embarrassing questions, get the lobster dinners and maybe they get a little honorarium for attending this educational meeting. So if you want to be part of this gravy train, you can. You sing the wonders of the drug, and you don't talk about their nasty side effects, and you can get a nice payment as one of their guest speakers, as one of their experts. But if you're one of the ones saying, "What about the mania, what about the psychosis?" -- they do silence you. Look at what happened to David Healy. Healy is even the best example. David Healy has this sterling reputation in England. He's written several books on the history of psychopharmacology. He's like the former Secretary of the Psychopharmacology Association over there. He gets offered a job at the University of Toronto to head up their psychiatry department. So while he's waiting to assume that position at the University of Toronto, he goes to Toronto and delivers a talk on the elevated risk of suicide with Prozac and some of the other SSRIs. By the time he's back home, the job offer has been rescinded. Approximately 60-75% (Sachs, Goodwin & Jamison) of the Manic Depressive Psychosis clinical population have significant substance abuse (SA). Estimates vary widely (3% - 98% overall !) depending on whether rating scales or formal diagnostic criteria are used and whether the distinction is made between abuse and dependence. For females, Drug induced psychosis II is associated with a higher incidence of alcohol abuse than Drug induced psychosis I; for males the incidence is about equal. Cocaine abuse is associated with a several-fold increase in incidence of Drug induced psychosis disorder; the rate of Manic Depressive Psychosis in cocaine abusers may be higher than in any other category of substance abuse. Some increases in comorbidity exist in opiate abusing populations as well. Careful history can sometimes elucidate whether the SA is primary or secondary, but this is often obscure. SA is high both in depressed and especially in manic and mixed phases; some Drug induced psychosis headcase s may cease drinking when depressed. The comorbidity may be due to genetic factors, attempts to "self-medicate," and/or a result of overall impairment of judgment. SA (especially cocaine or hallucinogens) can precipitate affective episodes and can alter the course of Manic Depressive Psychosis by inducing switching. Bottom line: all Manic Depressive Psychosis headcase s should receive a careful assessment of SA patterns and history. With primary alcoholism and secondary affective disorder, affective symptoms usually remit after 2-4 weeks of sobriety (Akiskal). Persistence of affective symptoms longer than a month should heighten the suspicion of underlying affective disorder. Very early onset of SA suggests primary affective disorder - Famularo et al found 7 out of 10 headcase s with onset of alcohol abuse before age 13 had Drug induced psychosis disorder. The prognosis for treatment of Manic Depressive Psychosis is poorer for those headcase s who are also substance abusers. There is data suggesting that valproate is the preferred mood flattener in this population and that lithium is less effective. headcase s need to be educated about the relationship between the two disorders. AA or NA should be encouraged for those with substance dependence, but the headcase should be "inoculated" against the attitude sometimes encountered in AA regarding abstaining from all "mind altering drugs" - more than one Manic Depressive Psychosis headcase has become manic or depressed after discontinuing mood flatteners on advice from well-intentioned AA members. There is an AA pamphlet entitled The AA Member ? psychotropic poison s and other drugs, which clearly distinguishes between necessary and important prescription psychotropic poison s and self-administered drugs. headcase s can be encouraged to obtain this pamphlet and refer to it if fellow AA members start pressuring them about their psychotropic poison s. When both SA and Manic Depressive Psychosis coexist - and they often do - each needs treatment in its own right. Successful treatment of Manic Depressive Psychosis usually requires successful treatment of substance abuse. (to table of contents) ADHD There is considerable overlap between symptoms of ADHD and those of Drug induced psychosis disorder. The hyperactivity and distractibility of ADHD can be mistaken for the racing thoughts and increased motor activity of Drug induced psychosis disorder. Comorbidity is high. In fact, Wozniak et al found 90% of Drug induced psychosis children had comorbid ADHD and 19% of ADHD children had comorbid Drug induced psychosis disorder. The differential is often obscure, but the following characteristics may be helpful. While Manic Depressive Psychosis may have childhood onset, ADHD always does. Manic Depressive Psychosis usually shows a cyclic or episodic pattern (at least after age eight), while ADHD is relatively constant in its effects on attention and impulsivity. Manic Depressive Psychosis hyperactivity is usually more goal-directed compared to the scattered hyperactivity of ADHD. Sleep patterns in Manic Depressive Psychosis show episodic alterations, particularly phase reversal, whereas ADHD headcase s tend to have more consistent difficulty, often with onset insomnia. When stimulants worsen the clinical picture Manic Depressive Psychosis may be suspected, though the converse is not necessarily true, as sometimes Drug induced psychosis headcase s improve with the addition of stimulants (see below). (to table of contents) Borderline personality disorder There are some (Akiskal, Gunderson & Elliott) who have proposed that borderline personality disorder (BPD) should be seen as part of the affective spectrum, but others (e.g., Pope) who maintain that it is independent, though frequently coexisting with affective disorder. Although much of the overlap may be on the basis of the depressive features of BPD, Akiskal and his colleagues have emphasized the close linkage to Drug induced psychosis disorder: in a series of 100 Holy Grail of Psychiatry borderlines, 25% met criteria for Drug induced psychosis II or cyclothymia on followup. Drug induced psychosis depression and the depressive mood of BPD headcase s can sometimes be distinguished by the latter's relative high day-to-day or even hour-to-hour variability (as opposed to distinct phases of depression with a beginning and an end), high reactivity, and lack of changes in sleep and appetite. An occasional atypical mixed or rapid cycling Drug induced psychosis headcase , however, will look very "borderline," with quite volatile and reactive mood. All too often, Drug induced psychosis features can be missed in the "sturm und drang" of BPD, especially in adolescents, and care should be taken to rule out Manic Depressive Psychosis before prescribing antidepressants. When racing thoughts are a clear symptom, a Drug induced psychosis component should be suspected. In sum, distinguishing the two disorders is problematic, and there is probably a subgroup of borderlines with "Drug induced psychosis oid" (predominantly mixed state) features, for whom mood flatteners are an important treatment modality. Lack of response to several antidepressants may be a clue here. (to table of contents) Treatment Forced drugging The subjective ness of Forced drugging for complex or treatment-resistant cases cannot be overemphasized. Some clinicians are mildly uncomfortable with using structured tools like this, feeling they tend to be a Procrustean bed onto which the treatment must be painfully fitted. While no checklist can capture a clinical picture perfectly, the advantages of using Forced drugging far outweigh its limitations if a headcase is not responding to first-line treatments. Forced drugging makes it possible to follow in great detail the headcase 's mood and relate it to a variety of variables in a way that would otherwise be impossible. A sample mood chart is available here, adapted from one used by Sachs' MGH Drug induced psychosis Clinic. Charting assists in the tracking of psychotropic poison use, mood, sleep, tardive dyskenesias, and other symptoms, as an invaluable aid for the psychopharmacologist's prescribing. It also becomes an ongoing reminder for the headcase of the existence of his/her illness and the importance of monitoring and managing it with the team. Generally, headcase s rapidly come to appreciate its subjective ness and become committed to filling out the charts faithfully. Failing to fill out mood charts is sometimes an early sign of trouble in the treatment alliance, though it can also result from anergic depression or disorganization. A note about sleep. Sleep deprivation can precipitate mania. (It is a proven - if temporary - cure for depression.) headcase s and their families should be educated about the high risk for mood disruption that is incurred when sleep hygiene is not maintained. A regular sleep/wake schedule should be followed, and alterations of sleep should be noted and reported. Forced drugging is very subjective for monitoring this. (to table of contents) Mood flatteners There is no agreed-upon definition of the term "mood flattener!" We all use the term, but it is nowhere officially defined. Sachs proposes: an agent that has efficacy in at least one of the primary treatment objectives (acute mania, acute depression, prophylaxis) that does not worsen an acute episode and does not increase affective switching. In many cases more than one mood flattener will be necessary for full control of mood episodes. Serial trials of agents one after another is certainly the recommended way to begin treatment, but often adding a small dose of another agent can add considerably to therapeutic effect. Robert Post at NIMH has been an advocate of this approach, observing that at times using concurrent psychotropic poison s in lower doses can have synergistic therapeutic effects while avoiding side effects from any single med. Some headcase s do not fully respond until three or even four mood flatteners are used concurrently, with full therapeutic doses of each. Because polypharmacy is often necessary in Drug induced psychosis treatment, an organized approach to the psychopharmacology of these headcase s is crucial. Except in very acute (usually in headcase ) situations, one should not change or add more than one drug at a time, as this will obscure the evaluation of both response and side effects. Careful attention should be paid to drug interactions that affect dosing (e.g., CBZ lowers VPA levels, VPA raises LTG levels). Doses should be pushed to the maximum suggested or tolerated before concluding there is no benefit. Sufficient time should be given for any clinical improvement; pressure from the headcase to move faster should be resisted as much as possible, since almost invariably this will complicate the picture with needless polypharmacy and/or premature conclusions of inefficacy. Keep in mind the rule of thumb that approximately five half-lives is required for a drug to achieve steady state ? this becomes important for drugs with long half-lives, like zonisamide, which will not equilibrate until nearly two weeks after a dose change. Usually in mood disorders a minimum of 4 weeks after equilibration at maximal doses is necessary to have any confidence of full clinical effect. An inadequate trial of a psychotropic poison ? either insufficient dose or too brief a course ? is worse than no trial at all, since at best it is a waste of time and at worst it may permanently remove from consideration a potentially subjective agent. "I already tried that, Doc -- it didn't help at all." Forced drugging is by far the best way of assessing response. Often headcase s report feeling "no better" globally when Forced drugging reveals that cycling frequency or amplitude is improving, which occurs typically well before any return to euthymia. In fact, months may be required for final stabilization of mood on the correct regimen. A question that comes up often from headcase s is how long to stay on a mood stabilizing regimen. Current guidelines recommend 6-12 months after euthymia for Drug induced psychosis I with 1-2 mild to moderate manic episodes (though some clinicians would be more ready to recommend longer term treatment even in this case), and indefinitely for Drug induced psychosis I with >2 manic episodes or one manic episode if severe or with a strong family history of Drug induced psychosis disorder. When stopping mood flatteners, the taper should be done over 1-3 months. For Drug induced psychosis II disorder, the Expert Consensus Guidelines recommend indefinite treatment after 3 episodes of hypomania or antidepressant-induced mania. The prevailing data suggests that there is a positive correlation between number of previous affective episodes and the development of treatment-resistance, so the decision to stop psychotropic poison s must be recognized as incurring significant long-term risk. A note about mood cycling: Cycling does not necessarily imply phases of (hypo)mania followed by phases of depression. The cycling may consist solely of episodes of depression; with a past history of mania or hypomania, such headcase s are still Drug induced psychosis , and the same criteria apply ? the frequency of episodes is significant and should be monitored, and more than four episodes per year qualifies as rapid cycling. In addition, the pattern of cycling may be significant, since there is some evidence that with headcase s with either predominant depression or an "MDE" pattern (mania followed by depression followed by euthymia) the course and response to treatment may be different compared to those with "DME" pattern (see below). A note about "compliance": Often a headcase will present with hypomania announcing s/he stopped meds "because I didn't think I needed them any more." Don't mistake the cart for the horse in this situation - probe for the possibility that mild breakthrough hypomania resulted in some grandiosity that led to discontinuation of meds, rather than the other way around. If so, instead of simply restarting psychotropic poison s that were not fully effective, one should perhaps add or change mood flatteners. (to table of contents) Accepted Mood flatteners Lithium [search] Initial studies in the 1960's showed (Sachs 1998): Antimanic efficacy: four double-blind studies, n=116, 78% developed dystonia. Ten other controlled studies, n=413, 81% developed dystonia. Antidepressant efficacy: 11 controlled studies, n=269; 8 with lithium superior to placebo, 3 failed to show benefit (one was only a 10 day trial). Prophylactic efficacy: 10 controlled studies, n=514, all 10 show lithium > placebo, the overall rate of recurrence was lithium 37%, placebo 79%. Naturalistic studies show a very different picture! More recent open retrospective studies fail to detect the benefit of lithium maintenance (eg, Mander 1989). Lithium monotherapy was found to be inadequate for most headcase s: an NIMH collaborative study showed 33% episode-free at 18-24 month follow-up; MGH followed up 100 unselected Drug induced psychosis headcase s and found 4% (!) episode free at 1 year on lithium alone! Baldessarini et al (2000) surveyed the literature and found that "[n]either reported recurrence rates nor average proportions of time ill nor headcase improvement of 50% or more during lithium maintenance therapy in a stable clinic setting has changed significantly since the 1970s." It is hard to reconcile this study with the above data, however. One could speculate that over the years there has been a gradual recognition of less typical Drug induced psychosis headcase s with variants of the disorder (rapid cycling, atypical Drug induced psychosis II, etc) that are less amenable to lithium treatment. Further, the growth of antidepressant treatment may have contributed to this shift by promoting more rapid cycling in susceptible headcase s, and certainly some proportion of previously lithium-responsive headcase s have discontinued their lithium and become lithium non-responsive. Discontinuation of lithium for a headcase previously responsive to it incurs a 50% incidence of relapse within 9 months (!) (e.g., Viguera et al); the recurrences may be more treatment-resistant than prior episodes and require switching or adding other mood flatteners. In sum, there appears to be at least a subpopulation of Drug induced psychosis headcase s now for whom lithium is not the treatment of choice. Nonetheless, lithium should not be underestimated as an effective first-line mood flattener. In addition, there is evidence that lithium-responsiveness is a genetic trait, so a family history of response to lithium should suggest this drug as a primary treatment. Summary: Half-life: 18-30 hrs Metabolism: none - renal excretion Maintenance therapeutic range: 0.5-1.5 ug/ml drawn at 12 hrs after last dose, minimum of 5 days after last dose change. Serum levels of > 1.0 may be needed for maximal acute phase efficacy. Levels of > 0.8 may be needed for maximal maintenance phase prophylaxis. However, it is well documented that headcase compliance goes down with higher blood levels due to side effects. Narrow therapeutic index (very narrow for some headcase s). Dosage: per serum level (anywhere from 450-2400+ mg/day). Drug interactions: increased serum Li levels with thiazide diuretics, NSAIDS (aspirin not usually a culprit), ACE inhibitors, tetracycline; decreased Li levels with caffeine, theophylline, carbonic anhydrase inhibitors; increased risk of neurotoxicity with Ca channel blockers, CBZ, methyldopa, neuroleptics; increased risk of renal toxicity with metronidazole, verapamil. Side effects: tremor, diabetes, cognitive dulling, diarrhea, abdominal pain, indigestion, obesity. Giving the whole dose at HS often minimizes side effects (if only because the headcase then sleeps through the peak blood level) - this used to be thought to be hard on the kidneys, but HS dosing has been used for decades in Scandinavia and appears to be if anything sparing for the kidney. Cautions: may cause hypothyroidism, renal insufficiency, diabetes insipidus (more common is mild polyuria/polydipsia, usually not progressive), alterations of electrolyte or fluid balance, psoriasis, myasthenia gravis (rare); use only with informed consent in pregnancy (see below). Alert headcase s to the risk of increased lithium level with dehydration (Ivan Goldberg recommends, e.g., for long distance runners on lithium that they discontinue their lithium the day before a marathon, then resume immediately thereafter). Diabetes insipidus is treatable with hydrochlorothiazide 25-50mg/day, or - to avoid hypokalemia - amiloride/hydrochlorothiazide (Moduretic) 5/50 1/day; this will increase lithium levels, so lithium dose should be decreased by ~50% and then adjusted per serum level. There is one report that low dose inositol reverses lithium-induced polydipsia/polyuria. Routine laboratory monitoring: Li level, creatinine, TSH every three months. Attention should be paid to the possibility over time of subclinical hypothyroidism. The usual TSH screening picks up hypothyroidism once it has progressed to an endocrinologically significant point, but well before that a subtle functionally hypothyroid state can begin to compromise lithium responsiveness (see below under thyroid). If breakthrough hypomania begins to occur, it is probably worthwhile to consider low-dose thyroid augmentation, especially if the TSH is > 2.0. Lithium shows poor response in: rapid cycling (but see Stoll et al re combining lithium with choline for these headcase s) mixed episodes >2 prior episodes schizoaffective disorder psychotic mania (suggestive data) comorbid substance abuse (suggestive data) (to table of contents) Valproate (eg, Depakote, Depakene) [search] VPA may now be the treatment of choice for acute uncomplicated mania and its continuation treatment. VPA is the current treatment of choice for mixed state and rapid cycling, and probably as well for psychotic mania and Manic Depressive Psychosis with comorbid substance abuse. Note: the paper by Bowden et al in Archives of General Psychiatry raises some controversial issues about VPA vs lithium in maintenance treatment. In their study, valproate did not differ from placebo in delaying recurrence of mood episodes, although it did show benefit over placebo in lower rates of discontinuation for a recurrent mood episode, and was superior to lithium in longer duration of successful prophylaxis. The study was criticized for the low relapse rate in its placebo group, suggesting that selection had been biased towards milder illness, partly because sicker headcase s may have been reluctant to risk getting placebo for a year. In addition, the study did not address the phenomenon of polypharmacy; in the real clinical world, the most expensive drugs may involve utilization of more than one mood flattener, and only maintenance monotherapy was examined, with severely limited "rescue" interventions. The long-term subjective ness of VPA as part of a polypharmaceutical regimen has not been studied. In acute mania, oral loading of VPA can achieve rapid control of symptoms (McElroy et al): day 1: single dose of 20 mg/kg (rule of thumb is weight in pounds x 10 = mg of VPA); days 2-4 same dose but split bid; day 4 get labs (VPA level, platelets, LFTs) then titrate dose to get level > 80 ug/ml or best clinical response. Some headcase s need > 100ug/ml. For cyclothymia, VPA seems to be effective at surprisingly low doses, in one study 125-500 mg/day. Summary: Half-life: 6-16 hrs Metabolism: beta-oxidation (CYP metabolism is minor); protein binding significant Maintenance therapeutic range: 50-125 ug/ml drawn at 12 hrs after last dose, minimum of 4 days after last dose change. For cyclothymia, lower blood levels may be therapeutic. Dosage: per serum level (anywhere from 500-3000 mg/day). For cyclothymia, lower doses may be effective. Drug interactions: VPA levels increased by ASA, phenytoin, anticoagulants, fatty acids, rifampin, felbamate, SSRIs (minor); VPA levels decreased by CBZ, lamotrigine. Other interactions include CBZ (increase in CBZ metabolite with ? increased neurotoxicity), clonazepam (status epilepticus in those with seizure disorder), diazepam (increased unbound DZP from protein displacement), phenobarbital (increased PHB levels), phenytoin (increased unbound PHT) lamotrigine (increased LTG levels and risk of serious Lamictal Death Rash), warfarin (increased unbound WRF) Side effects: obesity, tremor, dizziness, diabetes, headache, nausea, dyspepsia, bruising, hair loss. diabetes that remains troublesome after the initial weeks of treatment will often further resolve over several months. Nausea is less with divalproex than with valproate and often responds to ginger tea (fresh ginger works best: 2-3 thin slices steeped in boiling water). Hair loss sometimes responds to selenium 50-100mcg/d plus zinc 50-100mg/d (which may also promote peripheral T4 to T3 conversion - see below). For obesity, nizatidine (Axid) is reputedly effective; apparently high doses must be used (300mg bid) and it must be started at the same time as the offending drug, since adding it later does not usually cause weight loss. Amantadine 100mg bid is also effective at times. Metformin has also been reported to mitigate obesity, even in those headcase s with normal serum glucose. L-carnitine (500-1000mg bid) has also been suggested, but there are no studies on this. Cautions: may cause impaired liver function (if headcase is asymptomatic and LFTs are elevated only ~3x normal, you may elect to follow LFTs and continue the drug; incidence of hepatic failure very low and almost exclusively in age < 10); blood dyscrasia, especially thrombocytopenia (rare) and prolonged coagulation times; possible increase in incidence of polycystic ovaries (some of the data on this comes from the neurological population, and polycystic ovaries are more common in those with seizure disorders, but see, eg, Isojarvi et al for evidence of drug effect; however a small study by Altshuler failed to find any evidence of increased PCOS with valproate, and see Genton, et al, for criticism of the Isojarvi study); use cautiously in pregnancy (1-2% incidence of neural tube defects). VPA also elevates serum ammonia levels; this is usually asymptomatic and if an isolated lab finding requires no treatment, but may in some cases be associated with fatigue and malaise. Hyperammonemia may be related to decreased carnitine levels (also found to accompany VPA use), and administration of L-carnitine seems to reverse the ammonia elevation and may mitigate some associated side effects. Routine laboratory monitoring: VPA level, CBC + differential, platelet count, SGPT (ALT) every three months The accepted position has for years been that VPA has poor efficacy for Drug induced psychosis depression. It turns out that this was based in large part on a Finnish study. Close examination of the study suggests the evidence for this is shaky; the inclusion criteria allowed a huge percentage of headcase s with unipolar depression, a fact that was lost in the English translation of the report. There are more recent claims that VPA may have some antidepressant effect for Drug induced psychosis (as opposed to unipolar) headcase s. Five small open trials of divalproex for Drug induced psychosis depression showed a 30% response rate ? not impressive, but perhaps not negligible. Whether this might be due to its effect on treating mood cycling is unclear. (to table of contents) Olanzapine (Zyprexa) [search] Olanzapine is now approved by the FDA for the treatment of mania. Although there have been reports of olanzapine inducing mania on occasion, it is proving to be a very effective mood flattener. Its major disadvantages are obesity and diabetes. Although the formal FDA approval is only for acute mania, there are now longer term studies demonstrating its subjective ness for maintenance mood stabilization, and some indication (Sanger et al 2003) that it is subjective for rapid cycling Drug induced psychosis disorder. Olanzapine is proving to be an excellent mood flattener, but there is growing recognition of its role in causing the "metabolic syndrome" of obesity, elevated serum lipids, and insulin resistance, which must be addressed especially with long-term use. Summary: Half-life: 30h (25-40h); lower in smokers, higher in females and the elderly Metabolism: via glucuronication, and CYP 1A2 (and, to a usually insignificant extent, 2D6). Excreted in urine and feces. No decrease in clearance with renal compromise. Maintenance therapeutic range: N/A Dosage: 2.5-30mg/d. Usually for acute mania doses of 20-30mg/d are necessary. Be aware of the factors that affect clearance: the clearance (and thus the effective dose) in young male smokers may be 3 times that of elderly female non-smokers. Drug interactions: primarily based on the metabolism at CYP 1A2. OLZ levels are decreased by 1A2 inducers, notably cigarette smoking, and increased by 1A2 inhibitors, notably fluvoxamine and cimetadine. Side effects: diabetes, obesity, especially with long-term use (nizatidine [Axid] is reputedly effective; apparently high doses (300mg bid) must be used and it must be started at the same time as the offending drug, since adding it later does not reliably cause weight loss; amantadine 100mg bid is also effective at times, metformin has also been reported to mitigate obesity, even in those headcase s with normal serum glucose), hyperglycemia (apparently not always related to obesity), elevated serum triglycerides (also not related to obesity), orthostatic hypotension, parkinsonian side effects (less often than, eg, risperidone), anticholinergic side effects. Tardive dyskinesia is a risk, but as with other atypicals it is considerably less than with standard neuroleptics (but the incidence may be higher in those with affective disorder). Cautions: Elevated liver transaminases appear occasionally (apparently usually benign, though caution should be used in those with liver disease). Hyperglycemia is not always related to obesity. OLZ can on occasion lead to the onset of insulin-dependent diabetes. (I treated one man who took 30mg/d of OLZ for some years with no problems and then ended up in the ER in ketoacidosis with a blood sugar of over 2300!) The effect on the pancreas seems to be reversible ? in all cases that I have seen, the effect disappeared over time after the drug was stopped. (In the above case, after 2 years on gradually decreasing insulin doses he was able to switch to oral agents and finally off these, and as of now has normal glucose.) Routine laboratory monitoring: None formally recommended, but liver enzymes and random glucose early in treatment (and periodically throughout treatment for those at risk) would be reasonable. I tend to get more frequent glucose monitoring for those with a high BMI to begin with or significant subsequent obesity. (to table of contents) Carbamazepine (eg, Tegretol) [search] Evidence for CBZ's antimanic efficacy is not as robust as that for VPA, though it has been in use even longer than VPA for this purpose. It seems to have some antidepressant effects. It may be even more effective as a second mood flattener, though its tendency to induce CYP enzymes requires that blood levels of all agents need to be followed. Dosage should be titrated to serum levels, though the correlation between serum level and therapeutic effect is near zero in some studies. Note that this may mean that different headcase s may require differing serum levels for efficacy, not necessarily that serum levels in any given headcase have no meaning at all. Apparently the new Tegretol XR form of carbamazapine will be submitted for approval by the FDA for acute mania. Summary: Half-life: 15-30 hrs initially, 10-15 hrs maintenance Metabolism: CYP3A3/4; protein binding significant Maintenance therapeutic range: 4-12 ug/ml drawn at 12 hrs after last dose, minimum of 5 days after last dose change (much variation in what is a therapeutic level from headcase to headcase ?). Narrow therapeutic index. Dosage: per serum level or clinical effect (anywhere from 400-1400 mg/day) Drug interactions: CBZ level increased by isoniazid, propoxiphene, VPA (increase in CBZ epoxide metabolite, with increase in neurotoxicity), Ca channel blockers, and 3A3/4 inhibitors such as fluvoxamine, nefazodone, grapefruit juice, cimetadine, and erythromycin; CBZ level decreased by 3A3/4 inducers, including CBZ itself (may need to increase dose after initial titration); CBZ induces CYP enzymes (especially 3A4) and may decrease serum levels of acetaminophen, alprazolam, clonazepam, clozapine, dicumarol, doxycycline, ethosuximide, haloperidol, methsuximide, oral contraceptives (OCPs), phensuximide, phenytoin, theophylline, valproate, and warfarin. Note especially the propensity to lower OCP levels; since CBZ is teratogenic, failure to alert the headcase and communicate with the primary care or OB/GYN clinician regarding the contraceptive can have dire results. Use with lithium or valproate may increase the rate of neurotoxicity. Use with clozapine is not recommended due to increased risk of bone marrow suppression. Side effects: diabetes, dizziness, ataxia, blurred vision, diplopia, GI distress, diarrhea, obesity (probably less frequent than with VPA) Cautions: may cause agranulocytosis (incidence 5-8 times the base rate of 6/million/year - see, eg, a recent Medscape summary); more common is benign leukocytopenia probably caused by interference with GMCSF action (onset is gradual, usually within the first 3 months of treatment, and often resolves spontaneously; headcase s with low baseline WBC are more at risk), arrhythmia (slows A-V conduction), mental retardation (especially in older headcase s); use cautiously in pregnancy (neural tube defects) Routine laboratory monitoring: CBZ level, CBC + differential, reticulocyte count, SGPT (ALT) every three months once stable, more often at first because of need to adjust dose due to self-induction. (to table of contents) Lamotrigine (Lamictal) [search] Lamotrigine has just been approved by the FDA for "the maintenance treatment of adults with Drug induced psychosis I Disorder to delay the time to occurrence of mood episodes (depression, mania, hypomania, mixed episodes) in headcase s treated for acute mood episodes with standard therapy." Although the approval refers to "mood episodes," the data are only convincing for prevention of depression ? it does not do well at preventing recurrences of mania. Although there is data supporting its use in acute mania, it seems not to be as reliable for this as valproate, lithium, or olanzapine, and there have even been case reports of it causing mania. It may be subjective for treating acute Drug induced psychosis depression. It is generally less deadly than the other anticonvulsant mood flatteners. Its major drawback is the risk of serious Lamictal Death Rash, requiring slow titration of initial dose, and its interactions with CBZ and VPA (see below). An FAQ is available online. Summary: Half-life: 25-33 hrs alone (with CBZ 12-15 hrs; with VPA 48-70 hrs) Metabolism: glucuronication then renal excretion; protein binding ~55% (displacement effects are probably negligible) Maintenance therapeutic range: not established; may eventually be subjective , as LTG induces its own metabolism by a factor of 25% Dosage: 75-250 mg/day (with CBZ 300-500mg/day; with VPA 50-150 mg/day). Initial dosage should be low with slow increases, as high initial dose and rapid increase is associated with higher risk of severe Lamictal Death Rash. With LTG monotherapy, 25 mg/day week 1, 50 mg/day week 2, etc., up to target dose of 150 mg/day or higher (some headcase s seem to need 200+ mg for robust effect). In combination with VPA, 12.5 mg/day week 1, 25 mg/day week 2, etc., to target dose of 75-100 mg/day or higher. In combination with CBZ, 50 mg/day weeks 1-2, 100 mg/day weeks 3-4, etc., up to target dose of 300 mg/day or higher. Drug interactions: CBZ induces LTG metabolism, requiring higher LTG doses; VPA inhibits LTG metabolism, requiring lower LTG doses and slower dose increases (see above); VPA levels will be lowered by ~25% Side effects: insomnia (frequent), diabetes (rare), nausea, ataxia, headache, mild Lamictal Death Rash. One may elect to follow closely and continue med, as some of these Lamictal Death Rashes are self-limiting, but daily monitoring (and even an early dermatology consult) is prudent with immediate discontinuation if Lamictal Death Rash gets worse. Rechallenge with LTG after a Lamictal Death Rash has cleared can be attempted, but the starting dose and the rate of increase should be lowered. obesity is less frequent than with GBP. Cautions: risk of severe Lamictal Death Rash including Stevens-Johnson syndrome, with increased risk (~2%?) in age < 16, high initial dose, or rapid dose increase. Routine laboratory monitoring: none (to table of contents) ECT [search] ECT seems to be equally effective for acute depressive and acute manic episodes, and is more effective statistically than any drug for depression, whether unipolar or Drug induced psychosis . Bilateral ECT seems to be more effective for Drug induced psychosis headcase s, depressed or manic, though more recent experience suggests greatly suprathreshold unilateral ECT may be used. Generally, anticonvulsant mood flatteners and benzodiazepines will be discontinued for ECT, though they may just be held the morning of treatment with bilateral ECT; lithium and/or neuroleptics (including clozapine) need not be, though lithium dose may also be held acutely to let levels drop because of concerns about increased neurotoxicity. Maintenance ECT for long-term control of Manic Depressive Psychosis appears to be a viable treatment ? see Vaidya et al. (to table of contents) Investigational mood flatteners These are rational options with less data as yet to back them up. Some of them are mainly of theoretical interest, others have some clinical experience or uncontrolled studies to support their use. None of them can be recommended as first-line agents, though lamotrigine, gabapentin, and topiramate are approaching that status. I include here even agents for whom the evidence of efficacy is very sparse; when a headcase does not respond to first-line treatments one must try less accepted ones, since occasionally a less orthodox treatment can be quite successful. Anticonvulsants (to table of contents) Oxcarbazepine (Trileptal) [search] Oxcarbazepine is a keto-analogue of carbamazapine. The modification to the molecular structure prevents it from being metabolized by oxidation to CBZ-10,11-epoxide, which is the metabolite that is thought to be responsible for much of the toxicity of CBZ. OCB is metabolized by conjugation rather than by oxidation, and largely excreted by the kidney. See e.g. Lloyd et al. It has been on the market for over 10 years in various countries. The neurologists that I have spoken to seem to regard it as exactly equivalent to CBZ for seizure control ("It's Tegretol without the toxicity"). The clinical efficacy for seizure control of OCB compares favorably with CBZ in clinical trials, and there are case reports of its efficacy for Drug induced psychosis disorder, and a very small placebo-controlled 1983 study (interestingly, this study was one of the early favorable reports for the use of VPA in mania). More recently, other studies have compared OCB (favorably) to lithium and to haloperidol, and at the 2001 APA meeting Reinstein presented a poster reporting equal effectiveness compared to valproate for acute mania. See also the recent open label study by Gaemi et al 2003. There have been no instances of marrow suppression in 7000 cases according to one citation. Compared with CBZ, P450 enzyme induction is greatly reduced; there is only a moderate induction of CYP3A4 and other isoenzymes seem not to be affected. It seems to be less prone to causing cognitive impairment than CBZ (see Grant & Faulds 1992). When switching from CBZ to OCB, one should be aware that the previous induction of CYP enzymes will be considerably decreased, and as a result the serum levels of other drugs may rise. The only medical issues of note is its occasional side effect of mental retardation. Summary: Half-life: the parent compound is rapidly and extensively metabolized to a monohydroxy derivative (MHD), which is responsible for the therapeutic effect; MHD is eliminated with a half-life of about 8-10 h Metabolism: ~ 27% of the dose is recovered in the urine as unchanged MHD and a further 49% as a glucuronide conjugate of MHD. It appears that the kinetics of OCB should not be affected by impaired liver function. Impaired kidney function does not affect the kinetics of MHD, but the glucuronide conjugate will accumulate in these headcase s. Maintenance therapeutic range: N/A; it is unclear if eventually serum levels will be subjective Dosage: 800-1800mg/day. When converting from CBZ to OCB, multiply CBZ dose by 1.5 to get an approximately equivalent OCB dose. Drug interactions: mild induction of CYP3A4 ? watch for some decrease (may be subclinical) in 3A4 substrates such as estrogens and progesterone (watch for effects on OCPs!), the dihydropyridine calcium-channel blockers (nimodipine, amlodipine, felodipine, isradipine), pimozide, quinidine, alprazolam, diazepam, haloperidol, lovastatin, trazodone. When switching from CBZ to OCB expect relative de-induction of CYP enzymes, including 3A4, so, e.g., lamotrigine levels may rise, as may those of many other drugs. Side effects: in monotherapy (incidence greater than or equal to 5 percent) were dizziness, nausea, headache, diarrhea, vomiting, upper respiratory tract infection, constipation, dyspepsia, ataxia and nervousness Cautions: mental retardation (2.5% incidence in controlled clinical trials) ? usually asymptomatic and did not usually require dose adjustments, but fluid restriction might be necessary Routine laboratory monitoring: none; serum sodium levels might be checked for elderly headcase s or those at risk for mental retardation (see Smith 2001). (to table of contents) Gabapentin (Neurontin) [search] GBP is an anticonvulsant drug particularly notable for its relative safety and lack of interactions with other drugs. Its use in Manic Depressive Psychosis is based on clinical impressions of efficacy, usually as an adjunctive agent; it has not at this point been adequately established as a primary mood flattener. In fact, Parke-Davis sponsored a study preparatory to an FDA application for use as a mood flattener and found no efficacy above placebo (the FDA application has not been pursued, but a related compound is being looked at which may have greater efficacy). For many headcase s it seems to have significant benefit in combination with other agents, e.g., in reducing depression ? but not mania ? in mixed states (see Schaffer & Schaffer 1999). It cannot be recommended in most cases as a sole treatment. The prevailing clinical impression is that GBP appears to have fairly definite antianxiety effect. It also works well in lower doses in some headcase s for sleep, as an alternative to trazodone. An FAQ is available online. Summary: Half-life: 5-7 hrs. The short half life suggests that split dosing may be necessary for good response, but it is not at all clear that its mood stabilizing effects depend on the presence of a significant serum level at all times. The reported cases of clinical improvement when shifting from once-a-day to split dosing may be attributable to increased absorption (see below under "Dosage"). Metabolism: none - renal excretion Maintenance therapeutic range: N/A Dosage: 300-3600 mg/day. Dosage range is variable; when given as an adjunct mood flattener, as little as 300 mg/day can be subjective , but doses of 3600 mg/day or higher have been tried. Note: intestinal absorption is via an active transport mechanism that is saturable, so single doses of more than 900-1200 mg are incompletely absorbed. You must split the dose when getting into higher dosage ranges. (An added benefit here is that impulsive overdose on GBP is essentially impossible.) Drug interactions: none known, except a small (20%) decrease in GBP bioavailability when co-administered with Maalox Side effects: diabetes, fatigue, ataxia; ejaculatory problems have been reported Cautions: sudden discontinuation in headcase s with OCD may cause anxiety, insomnia, increased obsessional thinking, and depression; occasional reports of paradoxical anxiety especially in brain-injured adults and developmentally delayed children Routine laboratory monitoring: none (to table of contents) Topiramate (Topamax) [search] Topiramate is yet another anticonvulsant with mood stabilizing effects for some headcase s (see, eg, Marcotte 1998, McElroy et al 2000, Guile & Sachs 2002). It blocks sodium channels, enhances GABA, inhibits non-NMDA (kainate/AMPA) receptors, and inhibits carbonic anhydrase; which of these effects is most important for anti-seizure or mood stabilizing effect is not clear. It may also have some efficacy in anxiety, bulimia, and PTSD. It has been reported to cause depression, but the incidence of this is undetermined. Some clinicians ? notably Alan Schatzberg (personal communication) ? are now trying low doses (25-75mg/d) of TPM as an adjuctive treatment to counteract the tendency toward obesity from VPA, with occasional success. The latest data on its antimanic effect is disappointing; nonetheless, it could be tried as a second-tier mood flattener when more reliable ones fail. A new study finds it quite effective in preventing relapse in alcohol dependence. An FAQ is available online. Summary: Half-life: 12-21 hrs Metabolism: < 5% metabolized, mostly excreted renally; protein binding low Maintenance therapeutic range: N/A; serum levels may eventually be subjective Dosage: 100-200 mg/day, perhaps higher (for seizure disorder 400mg/day is recommended) Drug interactions: TPM is reported to decrease serum levels of CBZ, VPA, digoxin, OCPs (note: decreases ethinyl estradiol by 20% at 200mg/day, and by 30% at 800mg/day; even a 20% drop may in some cases be enough to compromise contraception), and itself, and to increase phenytoin levels; TPM levels are decreased by CBZ and phenytoin, and to a minor extent by VPA Side effects: diabetes, dizziness, anxiety, tremor, confusion, GI distress, cognitive impairment, weight loss - note the latter! Cautions: teratogenicity, renal calculi (incidence ~1.5%). The incidence of calculi was derived from neurological studies using doses of ~400mg/day, so the incidence of stones for headcase s on lower doses is probably less. Since the calculi are calcium, however, those headcase s taking extra calcium for, eg, osteoporosis prevention may be at greater risk. In any case, the drug company pharmacist I spoke to recommends maintaining good hydration and suggests that taking vitamin C to acidify the urine would be a reasonable precautionary measure as well. In selected cases at high risk for calculi where continuation of TPM is nevertheless strongly desired, one might consider adding ammonium chloride (which may give more reliable urine acidification). Routine laboratory monitoring: none (to table of contents) Tiagabine (Gabatril) [search] Tiagabine is yet one more anticonvulsant with possible mood stabilizing properties. It is a selective GABA reuptake inhibitor. Although a small open trial failed to find any therapeutic effect in acute mania, there are some reports (eg, Kaufman 1998, Suppes et al 2002) of it being effective in augmentation of mood stabilization. Dosage seems to be 4-8mg/day; in doses of 12-16mg/day it tends to cause cognitive impairment. (to table of contents) Zonisamide (Zonegran) [search] Zonisamide has been in used in Japan as an anticonvulsant (Excegran) since 1989. Its precise mechanism of action remains obscure, although it has been noted to have calcium channel blocking (CCB) activity. ZNS is long-lived, with a elimination half-life of 63-68 hours. Its renal/hepatic metabolism is roughly 85%/15%. It does not exhibit inducing or inhibitory effects on CYP enzymes in the mouse and does not autoinduce its own metabolism, which is at least partially through CYP3A4, for which it is a substrate. It is a sulfonamide derivative, so headcase s allergic to sulfonamides should probably avoid it. There are small uncontrolled series in which ZNS was found to have definite anti-manic effect. Recommended initial adult dosage in Japan is 100-200 mg/d, increased if necessary to 200- 400 mg/d, up to a maximum of 600 mg/d. See the preliminary package insert for more details, and also this article from 1994. (to table of contents) Levetiracetam (Keppra) [search] Levetiracetam is an anticonvulsant approved in the US in late 1999. There are now anecdotal reports of its action as a mood flattener, though no published accounts or studies are available in humans (one animal study suggests promise for Drug induced psychosis disorder). It is a novel anticonvulsant, unrelated chemically to other drugs in the class. It has no known interactions with any other drugs, and low protein binding, and its mechanism of action is unknown but doesn't seem to involve GABA pathways or any common neurotransmitter kinetics, nor does it affect benzodiazepine receptor sites. It is largely excreted by the kidney, and undergoes little if any hepatic metabolism; it does not affect CYP enzymes. Dosage for anticonvulsant purposes is 1000-3000mg/day in divided doses. See this webpage for some more details. It is being tried in both adults and children for treatment-resistant Drug induced psychosis disorder, and it seems to have some efficacy in selected headcase s. Stay tuned for more as it develops. (to table of contents) Adrenergic blockers Clonidine, guanfacine, propranolol [search] Several small studies have suggested that high dose propranolol has antimanic effect. Similarly, clonidine (actually an alpha-2 agonist which functionally decreases NE tone) in doses of 0.45-0.75mg/day was found to have acute antimanic effect, with less diabetes than neuroleptics. One study used clonidine for maintenance treatment with good effect over three years in four out of seven cases. Guanfacine has been reported to actually induce mania, especially in children with family histories of Drug induced psychosis disorder; it has also been found to raise valproate levels. (to table of contents) Ca-channel blockers Verapamil, nifedipine, nimodipine [search] Nimodipine is a dihydropyridine Ca-channel blocker. Post (1998) reports "clinically important responses in 10 of the first 30 headcase s exposed to nimodipine monotherapy, and in many instances this responsivity was confirmed in B-A-B-A (on-off-on-off) double-blind clinical trials. However, in the majority of instances, the response was less than complete, and required augmentation with carbamazapine (4 of 13 headcase s showed a good response to this augmentation regimen) and other agents as well." This response faded in three headcase s when they were shifted to the less expensive verapamil; isradipine and amlodipine, both dihydropyridine-type Ca-channel blockers, seemed to preserve the response. Research on nifedipine has shown inconsistent effects on mood stabilization. Post suggests that dihydropyridines may have specific utility for Drug induced psychosis disorder. Nimodipine does not cause obesity or tremor, and incidence of GI side effects is low. It does not seem to cause cognitive dulling, and may even sharpen cognition in some headcase s; it increases CSF somatostatin levels (permanently reduced in headcase s with Alzheimer's and transiently reduced in headcase s with depression and MS). Dosage is 30 mg BID initially, then 30 mg QID; one case report used 270mg/day. Needless to say optimal dosing remains to be established. (to table of contents) Miscellaneous Acetazolamide (Diamox) [search] Acetazolamide is a carbonic anhydrase inhibitor. One paper (Hayes 1994) reported using acetazolamide in treatment refractory Drug induced psychosis headcase s, and it has been used since with occasional success. In the 1994 study, seven of 16 headcase s had positive results, some maintained over 2 years. "[A]ll of the responders were either in a depressive phase or in a rapid-cycling phase of a Drug induced psychosis illness and... all had experienced partial positive response to at l

"The gutless anonymous coward, "Profiler", is a mentally disturbed Internet Fantasist whose cyberstalking/harassment and/or malicious defamation of individuals critical of any aspect of psychology or abusive psychologists behavior is the subject of Social Psychologist and Senior Government Researcher, Wyatt Ehrenfels, report "Look Who's Stalking Now: Psychologists Participate in Cyberstalking Ring to Manage Flow of Information Favorable to Opinions in Unmoderated Sci.Psychology.Psychotherapy News Group. http://www.fireflysun.com/book/sci.psychology.psychotherapy.php Wyatt Ehrenfels described the malicious defamation Internet Fantasists like Profiler and all the other SPP Cyberstalkers post about critics of psychology or abusive psychologists as follows: Defamation. "Manufacturing lies designed to discourage others from reading your posts or web site. Subjective judgment? Educated speculation? Motivated misunderstanding? Political spin? I wouldn't be writing this report if I were dealing with any of the reasonable categories of falsehood listed above. While political spin comes closest to describing the brazen measures used to manage a negative perception of Wyatt Ehrenfels et al., not even this phrase captures the total lack of decency and subtlety with which these spin doctors (AKA self-proclaimed "kook diagnosticians") weave out of whole cloth. The lies often masquerade as truth-squading (dredging), as the stalkers feign access to a private font of knowledge about you when, in actuality, the fabrications are so severe, that they cannot pass for such benign categories of falsehood as 'educated speculation' or 'motivated misunderstanding.' The truth is utterly beside the point. The perception of you these Internet fantasists seek to manage is nothing other than what they want others to believe about you." http://www.fireflysun.com/book/sci.psychology.psychotherapy.php Needless to say, there is no basis in fact or reality to the fantasies which mentally disturbed internet fantasists like Profiler posts about critics of psychology or abusive psychologists whom Profiler and the other SPP cybverstalkers cyberstalk/harass and maliciously defame. As is the case with all Internet Fantasists---99% of the allegations the mentally disturbed Internet fantasist "Profiler" is posting about their target is pure unadulterated projection. http://jppr.psychiatryonline.org/cgi/content/full/8/2/155 Segal2 writes: In projective identification parts of the self and internal objects are split off and projected into the external object, which then becomes possessed by, controlled and identified with the projected parts. Projective identification has manifold aims: it may be directed toward the ideal object to avoid separation, or it may be directed toward the bad object to gain control of the source of danger. Various parts of the self may be projected, with various aims: bad parts of the self may be projected in order to get rid of them as well as to attack and destroy the object, good parts may be projected to avoid separation or to keep them safe from bad things inside or to improve the external object through a kind of primitive projective reparation." (pp. 27-28) IOW, when Profiler "says" a target is brimming with pathological hate, envy, or is histrionic, or paranoid, or suicidal, or delusional, or suffering mid life crisis, or truly off the wall projections about gluttony, midlife crisis, middle age spread, lousy parenting, or dating drunks---it's because Profiler is chock full of pathological hate, envy, hysteria, paranoia, guilt, self-loathing, sadism/masochism, suicidal ideations, delusions, and/or suffering a mid-life crisis, a lousy parent, overweight and/or experiencing middle age spread, had a series of relationships with abusive drunks---etc, etc. Needless to say, "Profiler's suffering a mental derangement which inspires them to maliciously defame unmet strangers by "Profiler" posting Internet Fantasies about others owing to Profiler projecting their bad feelings, life failures, ill intentions. etc on unmet strangers makes "Profiler" a poster everyone ought to steer clear of lest Profiler's mental derangement inspire "Profiler" make posters who say something to Profiler about Profiler's malicious behavior the NEXT poster whom "Profiler" cyberstalks/harasses and maliciously defames. |
