This review examines new research on the inter-relationship between sleep disorders and mental disorders, with a focus on insomnia/sleep-wake rhythm disturbances and the pathophysiology and treatment of affective disorders. Recent evidence suggests that disturbed sleep and altered sleep-wake rhythms typically encountered in affective disorders provide important clues for prophylactic and therapeutic avenues.
