Association of insomnia with mania in Lebanese patients with bipolar disorder.

Abstract Objective To assess: (1) the association between insomnia experienced at admission, sociodemographic and other patients’ characteristics and mania; and (2) the variation of insomnia and mania before and after treatment in bipolar patients with manic episodes (type I). Methods Sixty-two patients were interviewed shortly after their admission to the hospital (after 3 to 5 days). The current symptoms experienced by the patients were assessed upon admission and again at discharge from the hospital. Results A poorer quality of sleep (higher PSQI scores) (Beta = 0.590) was significantly associated with higher mania, whereas the intake of SSRIs (Beta = −5.952) and TCAs (Beta = −8.181) was significantly associated with lower mania. Furthermore, highly significant reductions were reported in the PSQI scores (4.96 vs. 2.75, P  Conclusion Insomnia in patients with bipolar disorder type I is associated with mania, with a significant reduction of sleep problems seen during a period of approximately 20 days of hospitalization. Further longitudinal studies are needed to confirm the validity of our results and identify the causes. In the meantime, this research recommends a strategy to improve sleeplessness experienced during inter-episode phases may be helpful in preventing manic episodes in BD.
