| Outline of Final Research Achievements |
One hundred four BD (41 type I and 63 type II) outpatients and 73 age- and sex-matched major depressive disorder (MDD) outpatients participated in this study. Circadian rhythm sleep-wake disorders (CRSWD) was diagnosed by clinical interview and sleep logs based on the International Classification of Sleep Disorders, third edition. As a result, the rate of CRSWD in BD subjects was significantly higher than that in MDD subjects. A multiple logistic regression analysis revealed that comorbid CRSWD was significantly associated with BD in patients with remitted mood disorders.
Of the total 104 BD subjects, 51 (49.0%) subjects experienced relapse during the 48-week follow-up period. Multivariate Cox hazard regression analyses revealed that two or more previous mood episodes within the past year and comorbidity of CRSWD were significantly associated with the time to relapse of mood episodes.
