Official title
Enhancement of Therapeutic Learning in Obsessive-compulsive Disorder Using Transcranial Direct Current Stimulation
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Psychiatric disorders characterized by pathological fear and anxiety are common and often disabling. Despite their limitations, exposure therapies are among the most efficacious treatments for these disorders. Extinction learning is thought to be a core mechanism of therapeutic exposure. Extinction learning is mediated by a well-defined circuit encompassing the medial prefrontal cortex (mPFC), amygdala, and hippocampus. This raises the exciting possibility that direct engagement of this circuitry might enhance the response to therapeutic exposure. Transcranial direct current stimulation (tDCS) is a neuromodulation technology that can augment brain plasticity, learning, and memory. The proposed study will evaluate whether tDCS can improve therapeutic learning and memory processes among participants diagnosed with obsessive-compulsive disorder (OCD) This study aims to use tDCS to improve learning and memory processes within the context of an exposure laboratory challenge. Participants diagnosed with OCD will complete a two-day experimental study. On day 1, participants will receive sham (placebo) or active tDCS followed by approximately 50-minutes of individualized exposure. on day 2, participants will return to complete an additional 50-minutes of exposure. Subjective distress will be repeatedly monitored during exposure to allow for the modeling of within-trail and within-session learning and between-session recall of learning.
