Abstract
Background
Much remains unknown about the phenomenology of bipolar I disorder.
Aims
To determine the type of bipolar I mood episodes that occur over time, and their relative frequency.
Method
A total of 219 individuals with Research Diagnostic Criteria bipolar I disorder were prospectively followed for up to 25 years (median 20 years). Psychopathology was assessed with the Longitudinal Interval Follow-up Evaluation.
Results
Overall, 1208 mood episodes were prospectively observed. The episodes were empirically classified as follows: major depression, 30.9% (
n
= 373); minor depression, 13.0% (
n
= 157); mania, 20.4% (
n
= 246); hypomania, 10.4% (
n
= 126); cycling, 17.3% (
n
= 210); cycling plus mixed state, 7.8% (
n
= 94); and mixed, 0.2% (
n
= 2).
Conclusions
Cycling episodes constituted 25% of all episodes. Work groups revising ICD–10 and DSM–IV should add a category for bipolar I cycling episode.
