BIPOLAR RESEARCH UPDATE
The genes that influence our circadian rhythms and sleep cycles also influence the clinical features and age of onset of bipolar disorder.

Cannabis abuse causes bipolar-related psychosis to start an average of three years earlier than for people who did not abuse cannabis.

Treating even minor depressive symptoms after a first manic episode is integral to recovery after depression following a first manic episode because only depression was found to be related to functional outcomes at 6 months post a manic episode.

A 16-week trial found that aripiprazole seems to show promise as an adjunctive treatment or monotherapy in people with bipolar disorder who are unresponsive to mood stabilizers. Akathisia (inner restlessness) and slight weight gain were the main side effects. However, double-blind, placebo-controlled studies are necessary to measure the drug’s efficacy, tolerability and safety for bipolar patients.

A study of the effectiveness of acute treatment with interpersonal and social rhythm therapy on occupational functioning found that despite the lack of statistical significance, there was more improved occupational functioning than with a pscyhoeducational and supportive approach with no emphasis on functional capacity.
