I was reading in your post (Plixell) that you are bi-polar IV. I thought
there were only 2 types. I have looked up the type you mention that is
IV, what are the other ones called? Thanks. Dyl

Some doctors don't accept the limited definitions of bipolar disorder that are
described in the DSM. In order to account for a broader and more inclusive category
of bipolar and bipolar-like mental illness, Klerman and Young (1992) proposed an
expansion beyond the classical definitions, as follows:

Bipolar I - Mania and Major Depression
Bipolar II - Hypomania and Major Depression
Bipolar III - Cyclothymia
Bipolar IV - Antidepressant induced hypo/mania
Bipolar V - Major Depression with a family history of bipolar disorder
Bipolar VI - Unipolar Mania

There is also an alternative diagnostic structure proposed by Aniskal (1999), which
is as follows:

Bipolar I: full-blown mania
Bipolar I ?: depression with protracted hypomania
Bipolar II: depression with hypomanic episodes
Bipolar II ?: cyclothymic disorder
Bipolar III: hypomania due to antidepressant drugs
Bipolar III ?: hypomania and/or depression associated with substance use
Bipolar IV: depression associated with hyperthymic temperament


Proposed subtypes V and VI have not yet been characterized, but presumably they will
involve episodic anxiety disorders and/or seasonal mood states as well as mood
disorders co morbid with various anxiety disorders of an episodic nature.


Usually, when people refer to diagnoses beyond bipolar I and II, they are referring
to the Klerman and Young typology.
