Summary
This study tested whether a six-week sleep therapy program (CBT-I) could improve thinking and memory in older adults aged 60-85 with insomnia. Two hundred participants were randomly assigned to either CBT-I or a sleep education program. A small group also had brain scans to see if better sleep slowed the buildup of amyloid plaques, which are linked to Alzheimer's disease. The goal was to see if treating insomnia could help protect the brain.

Active substance
Cognitive Behavioral Therapy for Insomnia (CBT-I)
What this could lead to
If successful, this could show that treating insomnia improves cognitive function and may slow brain changes linked to Alzheimer's disease.
What could go wrong
This is a completed study with 200 participants, but the results are not yet widely confirmed. The link between sleep and brain amyloid is still uncertain, and individual results may vary.
