Clinical Trial: Transcranial Magnetic Stimulation Treatment of Hoarding Disorder

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: Transcranial Magnetic Stimulation Treatment of Hoarding Disorder

Brief Summary: This is multiple baseline study including up to three participants with a primary diagnosis of hoarding disorder. All patients will receive unblinded repetitive transcranial magnetic stimulation study intervention.

Detailed Summary: Study assessments will be conducted at pre-baseline, weekly during baseline assessment (until a stable baseline is established, but not less than 2, 4, and 6 weeks for patients respectively), weekly during treatment, and at post-treatment. Magnetic resonance imaging (MRI) will be competed at pre-baseline, pre-treatment, and post-treatment. Treatment will entail daily (5 days/week) sessions of repetitive transcranial magnetic stimulation using the Neurostar Therapy System for 6 weeks employing right-sided, low frequency stimulation (1 Hz, 900 pulses/session for 30 sessions, 27,000 total pulses, intensity at 90% of the passive motor threshold) to the dorsolateral prefrontal cortex (DLPFC). Neuronavigation will direct coil placement over the DLPFC based upon structural MRI.

Current Primary Outcome: The Saving Inventory-Revised (SI-R) Total Score [ Time Frame: Pre-baseline, Post-baseline/Pre-treatment, Post-treatment, 2-Month Follow-up ]

The Saving Inventory-Revised (SI-R) is a self-report measure which includes 23 items assessing the severity of hoarding symptoms including difficulty discarding, acquiring, and clutter. The 23 items are added for a total score which ranges from 0 to 92 and with higher score indicating more severe hoarding symptoms.


Original Primary Outcome: change in discarding subscale of The Saving Inventory-Revised (SI-R) [ Time Frame: Participants will be assessed weekly for the duration of the study (average duration will be 10 weeks) ]
