Official title

Clinical, Neurocognitive and Neuroimaging Variables Associated With Response to Treatment in Patients With OCD

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study consists of a naturalistic follow-up of subjects with Obsessive-Compulsive Disorder (OCD) that have participated in a global study investigating brain signatures of OCD funded by the National Institutes of Mental Health (RO1MH113250), with the following participant sites: the US (Columbia University, PI: Helen Blair Simpson), Brazil (University of Sao Paulo, PIs: Euripedes Miguel and Roseli G Shavitt), India (National Institutes of Mental Health, PI: Janardhan Reddy), The Netherlands (VU Amsterdam Medical Center, PI: Odile van den Heuvel), and South Africa (University of Cape Town, PI: Dan Stein; Stellenbosch University, PI: Christine Lochner). In this cross-sectional study, two-hundred and fifty unmedicated subjects with OCD (50 per site) will be assessed for clinical, neurocognitive and neuroimaging data. After completion of this study, participants willing to receive evidence-based treatments for OCD will be treated with the available resources in each site and will be assessed for treatment response status periodically, with a final assessment after 1 year of naturalistic follow-up. At this point, we will investigate baseline clinical, neurocognitive and neuroimaging variables associated with the treatment response status.
