Background: Bipolar disorder, characterized by episodes of mania, hypomania and depression is associated with sleep disturbances and circadian rhythm disruption. These changes have significant impact on quality of life and in the disease prognosis.Aims: Review of the main sleep disturbances observed in the bipolar disorder, their clinical impact and the hypothetical pathophysiological mechanisms involved.
Methods: We conducted a non-systematic review of the literature in English through research in PubMed with the keywords “sleep disturbance”, “bipolar disorder”, “polysomnography”.
Results and Conclusions: Complaints about sleep pattern changes may occur during any phase of the disease. These in clude frequent night-time awakenings, poor sleep quality, reduction of the total sleeping time and decreased latency and increased density of REM sleep. The treatment of the sleep disturbances observed in bipolar disorder should be considered a priority, since it prevents symptoms recurrence and facilitate the socio-professional integration, thus providing greater success in patient’s rehabilitation and quality of life.
