Q

What are the ABCD Characterisations for Manic Episodes

A

A) A distinct period of abnormally and persistently elevated, expansive, or irritable mood and abnormally and persistently increased goal directed activity or energy, lasting at least 1 week and present most of the day, nearly every day (or any duration if hospitalization is
necessary)

B) During the period of mood disturbance and increased energy or
activity, 3+ of the following symptoms (four if the mood is only irritable) are present to a significant degree and represent a noticeable change from usual behavior:

  1. Inflated self-esteem or grandiosity
  2. Decreased need for sleep
  3. More talkative than usual or pressure to keep talking
  4. Flight of ideas or subjective experience that thoughts are racing
  5. Distractibility, as reported or observed
  6. Increase in goal-directed activity or psychomotor agitation
  7. Excessive involvement in activities that have a high potential for painful consequences

C) The mood disturbance is sufficiently severe to cause marked
impairment in social or occupational functioning or to necessitate
hospitalization to prevent harm to self or others, or there are psychotic features

D) The episode is not attributable to the physiological effects of a
substance or to another general medical condition

Q

What is the difference between a manic episode and a hypomanic episode

A

A hypomanic episode is:
* Shorter, less severe version of a manic episode
* Lasts at least four days
* Has fewer and milder symptoms
* Associated with less impairment than a manic episode
* May not be problematic in and of itself, but usually
occurs in the context of a more problematic mood disorder
