The sleep of 10 bipolar patients was recorded for five consecutive nights following their recovery from a depressive episode. In all respects except the number of arousals, their sleep did not differ reliably from that of 10 sex and age-matched control subjects. We conclude that sleep measures are unlikely to be useful as trait markers of a depressive diathesis in bipolar disorder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
