Abstract
Poor sleep quality prevalence in bipolar disorder is 52% during euthymia and 63% during the depressive phase.
- Individuals with euthymic bipolar disorder reported worse sleep quality and had longer total sleep time and sleep onset latency compared to controls.
- Higher percentages of rapid eye movement sleep were observed in the depressive phase of bipolar disorder.
- The manic/mixed phase exhibited shorter total sleep time, lower sleep efficiency, and longer sleep onset latency.
- Bipolar disorder showed greater variability in sleep duration and continuity during euthymia.
- Prominent differences in sleep measures were noted between sleep diary reports and objective assessments.
