Can a 20-Week class rewire the hoarding brain?
NCT ID NCT02306174
First seen Aug 17, 2026 · Last updated Aug 18, 2026 · Updated 1 time
Summary
This trial tests whether a 20-week group class, combining cognitive rehabilitation with exposure therapy, can reduce the core symptoms of compulsive hoarding. Participants with hoarding disorder, who may also have mood or anxiety issues, will attend 90-minute sessions involving sorting, discarding, and non-acquisition exercises. The goal is to see if this structured behavioral approach helps people let go of clutter and feel less distressed.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A 20-week group behavioral course combining cognitive rehabilitation and exposure therapy, including sorting, discarding, and non-acquisition exercises.
- What this could lead to
- If effective, this group class could offer a structured, non-drug treatment to reduce hoarding symptoms and improve daily functioning.
- What could go wrong
- The trial is small and early, so results may not apply broadly. Some participants might find exposure exercises distressing, and benefits may vary.
