Welcome to the Center for OCD and Related Disorders


Happy New Year! We want to take this opportunity to wish all our current, past, and future friends and supporters a happy and healthy 2014. Our mission is to improve the lives of individuals with obsessive-compulsive disorder (OCD) and related disorders by advancing our understanding and treatment of these impairing conditions. Here are some highlights of what we accomplished in 2013 and what we're working on in 2014:

In 2013 we educated the public about our research findings through:

  • Papers in Major Scientific Journals:
    • 'Cognitive-behavioral therapy vs risperidone for augmenting serotonin reuptake inhibitors in obsessive-compulsive disorder: a randomized clinical trial' (full text)
    • 'Capacity to delay reward differentiates obsessive-compulsive disorder and obsessive-compulsive personality disorder' (full text)
    • 'Randomized controlled crossover trial of ketamine in obsessive-compulsive disorder: proof-of-concept' (full text)
    • 'Reported cortico-striatal stimulation generates persistent OCD-like behavior' (full text)
  • Blogs:
    • A series of blog talk radio shows, which discussed current and future directions of OCD treatment and research, throughout October
    • Our own Dr. Carolyn Rodriguez is now a regular contributor to the Huffington Post

Here are some of our plans for research on OCD & related disorders in 2014:

  • Treatment studies investigating:
    • Whether patients need their medications to stay well after receiving Exposure and Ritual Prevention Therapy EX/RP (IRB #6628). Learn more here
    • How to extend the anti-obsessional effects of ketamine (IRB #6811)

  • Studies that investigate the brain basis of OCD to identify new targets for treatment development (IRB #6430)
  • Studies of Hoarding Disorder, an OCD-related diagnosis which was added to the DSM-5 in 2013 (Read more at our new Hoarding Disorder Site)

Thank you for your ongoing commitment to us and our shared mission. If you would like to participate in our research studies or contribute to our research fund in 2014, please contact us at (646)774-7000.

On behalf of our team, I wish you all the best in 2014!

Participating in a Study:

Are you on medication for OCD but still having bothersome symptoms? You may be eligible for our new treatment study determining who can achieve wellness through a Cognitive Behavioral Therapy called Exposure and Response Prevention (EX/RP), and then safely come off OCD medication while still maintaining wellness. For more information about this study and the treatment of OCD at our center, please visit the study site or contact Dr. Marcia Kimeldorf at (646)774-8049.

If you would like to participate in another treatment study or contribute to our research fund, please contact us at (646)774-7000.

Our current studies include:

  • Investigating whether patients on an adequate treatment dose of an SRI who are still having bothersome symptoms can achieve wellness with the addition of Exposure and Ritual Prevention treatment (EX/RP), and then, whether those who achieve wellness can safely slowly discontinue their medication treatment and maintain wellness (IRB#6628). See more here

  • Evaluating whether people with OCD, social phobia, and anorexia nervosa differ from each other in their stress reactivity or their response to new information (IRB#6430). See more here


  • Investigating symptoms of obsessive compulsive personality disorder (OCPD) to aid in the development of treatment, while clarifying the relationship between OCPD and OCD (IRB#5979). See more here


  • Using mouse models to study the brain mechanisms underlying repetitive behaviors.


  • Developing innovative treatment approaches for compulsive hoarding.
