What this trial studies

This study evaluates the effectiveness of combining exposure-based Cognitive Behavioral Therapy (CBT) with Transcranial Alternating Current Stimulation (tACS) in treating patients with obsessive-compulsive disorder (OCD). A total of 120 participants will be randomized into three groups: one receiving active tACS with CBT, another receiving sham tACS with CBT, and a waiting list group. The treatment will consist of 10 sessions over two months, with assessments of OCD symptoms and EEG monitoring to explore the neural mechanisms involved. The goal is to determine if the combination of tACS and CBT enhances treatment outcomes for OCD patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-60 with a confirmed diagnosis of OCD and a Y-BOCS score of 16 or higher.

Not a fit: Patients with severe OCD symptoms that hinder assessment, those with serious medical or neurological conditions, or those currently on antiepileptic medication may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve treatment outcomes for patients with OCD.

How similar studies have performed: While the combination of CBT and tACS is a novel approach, previous studies have shown promise in using tACS for various neurological and psychiatric conditions.
