Which actigraphic variables optimally characterize the sleep-wake cycle of individuals with bipolar disorders?

Including sleep variability and activity parameters alongside measures of sleep quantity improves the characterization of cases of euthymic BD and helps distinguish them from HC. If replicated, the findings indicate that traditional approaches to actigraphy (examining mean values for the standard set of sleep parameters) may represent a sub-optimal approach to understanding sleep-wake cycles in BD.
