Study Summary
The overall aim of this project is to compare sleep patterns and melatonin profiles in individuals with bipolar disorder during depression and after remission. The hypothesis is that sleep time, rest-activity cycles and melatonin onset will be delayed during depression and become less delayed after remission.
Primary Outcome
Subjects will be instructed in the procedures used for home-based, self-collection of saliva samples. The protocol developed by Sit and colleagues at the University of Pittsburgh (attached), will be used. This involves obtaining ten saliva samples, one every 30 minutes, over a 4.5 hour period. This protocol contains instructions about ambient lighting, posture, exercise, eating, and use of the oral swabs and collection kits.
