Summary

This study looks at how cognitive behavioral therapy for insomnia (CBT-I) changes a specific brain receptor (mGluR5) in people with major depression. 42 adults with depression and insomnia will receive online CBT-I and undergo PET brain scans before and after treatment. The goal is to understand the brain chemistry link between better sleep and improved mood.

Active substance

Cognitive Behavioral Therapy for Insomnia (CBT-I) and PET scan tracer [11C]ABP688

What this could lead to

If successful, this could reveal a brain mechanism explaining why improving sleep helps depression, potentially guiding new treatments.

What could go wrong

This is a small, early-phase mechanistic study with only 42 participants, so results may not apply widely. It aims to understand biology, not test a new therapy.
