Statement of Need

Obsessive-compulsive disorder (OCD) is a chronic disorder characterized by uncontrollable and reoccurring thoughts and excessive urges to repeat certain actions. Approximately 2-3% of the population have OCD. For people with OCD, obsessions and compulsions can be intrusive, anxiety-provoking, time consuming and can cause major distress ultimately impairing work, social or other important functions. OCD is typically treated with medication, behavioral therapy or a combination, however, 20-30% of OCD patients do not respond to medications and behavioral therapy. There is a need to identify new treatment options for OCD patients.

Essential tremor (ET) is a nervous system disorder that causes involuntary and rhythmic shaking that can affect almost any part of the body. ET has a 9% prevalence rate in people over the age of 60 years. ET has significant detrimental impact on quality of life, interfering with the ability to perform activities of daily life including grooming, feeding, dressing and writing. Treatment of ET may include anticonvulsant medications and beta blockers, surgical interventions, and deep brain stimulation, all of which have limited efficacy and side effects.

Neurosurgical therapies such as stereotactic radiosurgery can provide an important option for patients suffering from OCD and ET in whom traditional therapies have not been effective.

Target Audience

This program is designed to meet the needs of radiation oncologists, neurosurgeons, residents-in-training, medical physicists and healthcare professionals with interest in learning about the rationale for the use of stereotactic radiosurgery for the treatment of OCD & essential tremors.

Activity Objectives

  • Describe SRS indications and contraindications for obsessive compulsive disorder and essential tremors
  • Explain key SRS contouring and treatment planning issues related to functional disorders
  • Discuss rationale for single fraction SRS for functional disorders

Accreditation Statement

In order to successfully complete this knowledge-based continuing education activity, the participant must register for the activity, view the educational sessions, complete the online examination and activity evaluation.

Continuing Medical Education (CME) Statement

A note on browser incompatibility:

  • We have tested IE 6.x in controlled configurations and we can stream successfully, but there are some versions that may not support the RTMP streams we push out - basically new technology that old technology can't handle.
  • Possible remedy: upgrade browser version, try alternate browsers such as Firefox.
  • Flash Player Version 11 or higher. If you have an older version it would be best to upgrade now. It's free and does not require a reboot.
