At the in-person evaluation, after signing a consent form, a more detailed interview about sleep problems, and medical and psychiatric history will be obtained by the Duke Structured Sleep Interview, including evaluations of cognitive impairment and depression. Exclusion criteria will further be evaluated by the following given solely at the office evaluation: Acute/Unstable Chronic Illness checklist, Berlin Questionnaire, Columbia Suicide Severity Rating Scale (C-SSRS), DUKE Structured Sleep Interview, Hamilton Depression Rating Scale (HDRS24), Life Stressor Checklist, Mini International Neuropsychiatric Interview Version 5 (MINI), Montreal Cognitive Assessment (MOCA), Morningness-Eveningness Questionnaire, Sleep Disorder Questionnaire (SDQ), Sleep Related Behavior Questionnaire, and the Thought Control Questionnaire Insomnia-Revised (TCQI). Subjects will additionally be set up with PSG equipment. The PSG will be completed in the subject's own home and be used to screen for Obstructive Sleep Apnea and Periodic Limb Movement Disorder. Subjects will return to the lab the next morning to have the equipment removed.
