Trial Overview
NCT ID: NCT06834217 Phase: NA Enrollment Target: 180 Status: Recruiting
Obsessive-compulsive disorder (OCD) is associated with substantial impairments in quality of life and is among the most disabling psychiatric disorders. Exposure therapy is among the first-line of treatments for obsessive-compulsive disorder (OCD) . Extinction learning is thought to be a core mechanism of therapeutic exposure. Fear and safety signal learning are traditionally associated with activity and connectivity within the canonical corticolimbic "fear circuit", which includes the amygdala, medial prefrontal cortex (mPFC), and hippocampus. Transcranial direct current stimulation (tDCS) is a neuromodulation technology that can augment brain plasticity, learning, and memory. The proposed study will test if obsessive-compulsive disorder (OCD) is associated with inhibitory safety learning deficits and if transcranial direct current stimulation (tDCS) normalizes functional connectivity and safety signal processing to recover extinction deficits in obsessive-compulsive disorder (OCD).
