Cognitive-Behavioral Therapy for Obsessive-Compulsive Disorder (OCD)

This study is investigating what, if any, changes in brain chemistry take place in adults with OCD as a result of cognitive behavioral therapy (CBT). We will measure amounts and distribution of glutamate in the brain using MRSI (Magnetic Resonance Spectroscopic Imaging) scans before and after 4 weeks of CBT.

The study offers:

  • Diagnostic evaluation
  • 4 weeks of FREE intensive CBT (exposure and response prevention): 90 minutes/day, 5 days/week
  • MRI/MRSI brain scans
  • Neurocognitive testing
