First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested suvorexant (Belsomra), an FDA-approved sleep medication, in 40 older adults with insomnia. Participants took the drug or a placebo for two weeks while wearing a motion tracker and completing smartphone surveys about their sleep, mood, and thinking. The goal was to see if suvorexant improves not just nighttime sleep but also daytime symptoms like fatigue and concentration.
