This study explores whether rapid non-invasive brain stimulation can help reduce hoarding disorder symptoms.
Interventions
DEVICE
MagPro X100 by MagVenture
Participants will receive 5 session per day of TBS for 6 days (30 sessions total). Six treatment days have to occur within a 2 week period. Each session will be comprised of 1800 pulses, using a MagVenture MagPro X100.
Primary outcome measures
Change in Compulsive Acquisition Scale (CAS)
Time frame: Change from baseline to 3 weeks after treatment starts
The Compulsive Acquisition Scale (CAS) is an 18-item questionnaire that measures the extent to which individuals acquire and feel compelled to acquire possessions. The total score (sum of 18 items) ranges from 0 to 126. Total score higher than 48 shows significant difficulty with acquiring.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
