What is deep brain stimulation (DBS)?

  • A new brain stimulation procedure approved by the US Food and Drug Administration for chronic and treatment resistant obsessive compulsive disorder (OCD).
  • A pulse generator, similar to a heart pacemaker and implanted under the chest, sends electrical pulses into the brain.
  • Electrodes implanted in your brain activate regions thought to be associated with your OCD.

What is DBS used for?

  • DBS has been proven as an effective treatment for neurological disorders such as essential tremor and Parkinson’s disease
  • In addition, DBS is being studied as an alternative or added treatment for severe depression and obsessive compulsive disorder when other standardized treatments including:
    • Antidepressant medications,
    • Psychotherapy or
    • Electroconvulsive therapy (ECT) fail to produce significant improvements.
DBS does not necessarily replace your medications.

  • Two to three weeks after the surgery:
    • Your doctor will activate the device at his office.
