Active clinical trials for "Obsessive-Compulsive Disorder"

To investigate the neuro-mechanisms underpinning persistent avoidance in OCD patients

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records.

In this study the investigators will use semi-structured interviews to qualitatively analyse patient and family member experiences with either deep brain stimulation or other forms of psychiatric neurosurgery.

The purpose of this study is to characterize and compare irregularities in dopaminergic function in fronto-subcortical circuits, between Parkinson's Disease patients (ON and OFF medication) and patients with obsessive-compulsive disorder, by examining performance on cognitive tasks involving cognitive flexibility, decision-making, and attentional bias.
