Official title
The Impact of Suvorexant on Cognitive Function and Daytime Symptoms Among Community-dwelling Older Adults With Insomnia: A Placebo-controlled, Randomized Clinical Trial Using Remote Monitoring and Ecological Momentary Assessment
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this study is to examine the impact of suvorexant, an FDA-approved insomnia medication, on daytime symptoms (as measured by the Daytime Insomnia Symptoms Scale: cognition, positive mood, negative mood, and fatigue/sleepiness) among older adults with insomnia. The primary hypothesis is that relative to placebo, suvorexant will improve sleep and daytime symptoms. The word "placebo" refers to a harmless pill with no therapeutic effect.
