Study Description
Brief Summary:
The purpose of this study is to understand how ketamine brings about rapid improvement in Obsessive-Compulsive Disorder (OCD) symptoms.

Condition or disease Intervention/treatment Phase
Obsessive-Compulsive Disorder Drug: Ketamine Drug: Midazolam Phase 2

Detailed Description:
Obsessive-Compulsive Disorder (OCD) is a chronic and disabling disorder that costs the economy over $2 billion annually and represents a significant public health problem. This study aims to build on our discovery that a potent NMDA receptor antagonist, ketamine, has rapid (in hours) and robust therapeutic effects in OCD. The proposed projects test the acute mechanism of action of ketamine at the level of molecules, circuits, and network synchrony to determine how NMDA receptor antagonism modifies the underlying pathology of OCD to relieve repetitive thoughts and behaviors.
