What this trial studies

Researchers will deliver accelerated intermittent theta-burst stimulation (iTBS) using a MagPro X100 device to adults with primary hoarding disorder who have significant symptom severity. Participants will attend repeated, rapid in-person brain stimulation sessions at Stanford University Medical Center and are screened for exclusions such as prior TMS/ECT, implanted devices, pregnancy, or unstable medical/psychiatric conditions. The protocol targets brain regions involved in decision-making and emotional regulation with the goal of reducing difficulty discarding and clutter. Outcomes will include changes in hoarding symptom severity and the tolerability of the rapid iTBS schedule.

Who should consider this trial

Good fit: Adults aged 18–70 with a primary diagnosis of hoarding disorder and sufficiently severe symptoms who can consent and attend in-person iTBS sessions are the ideal candidates.

Not a fit: People who are pregnant or nursing, have implanted devices or prior TMS/ECT exposure, unstable psychiatric or medical conditions, or a different primary diagnosis are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, this could provide a non-invasive treatment option that reduces hoarding symptoms beyond what therapy alone achieves.

How similar studies have performed: TMS and iTBS have shown mixed but sometimes promising results in related conditions like OCD and depression, while direct evidence specifically for hoarding disorder is limited and largely preliminary.
