Study Summary

This trial will test whether a new method of transcranial magnetic stimulation can specifically help people with OCD who experience contamination/washing symptoms.

Who is the study for?
This trial is for adults aged 18-55 with Obsessive-Compulsive Disorder (OCD), specifically those who struggle mainly with contamination/washing symptoms. Participants should score ≥8 on a specific OCD scale and not have started new therapy or changed medications recently. It's not open to individuals using certain psychiatric drugs, those with a recent substance use disorder, or anyone pregnant.Check my eligibility
What is being tested?
The study tests individually targeted neuromodulation techniques: iTBS and cTBS against a sham procedure to see if they can reduce contamination-based OCD symptoms more effectively than current general treatments.See study design
What are the potential side effects?
While the description doesn't specify side effects, transcranial magnetic stimulation can sometimes cause discomfort at the stimulation site, headache, lightheadedness, or seizures in very rare cases.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the most populous cohort of individuals participating in this research?

"Affirmative. According to records on clinicaltrials.gov, this medical experiment – which was initialy posted on July 1st 2022 – is actively seeking out potential participants. There are 50 spots to fill at one trial site."

Answered by AI

Are any individuals aged 20 or over permitted to join this experiment?

"In order to be considered for this medical study, the applicant must fall between 18 and 55 years old as stipulated in the eligibility requirements."

Answered by AI

Are there any open slots remaining for this trial?

"Affirmative. Clinicaltrials.gov data shows that this clinical trial is still searching for participants as of November 14th, 2022; the study was initially published on July 1st, 2022 and requires 50 enrollees at a single site."

Answered by AI

Can I join the research project?

"This trial seeks 50 individuals aged 18 to 55, who struggle with obsessive-compulsive disorder. Crucially, they must have CONTAM as their foremost symptom dimension (highest score on the Dimensional Yale-Brown Obsessive Compulsive Scale), not initiate a new course of exposure and response prevention therapy within 8 weeks of enrollment (continuing ERP will be allowed if begun more than 8 weeks before enrolment) and achieve at least an 8/20 on Dimension 4 of the DYBOCS."
