Overview

For some patients with severe OCD, neither medication, support groups nor psychological treatments are helpful in alleviating obsessive-compulsive symptoms. These patients may choose to undergo psychosurgery as a last resort. Deep-brain stimulation and vagus nerve stimulation are possible surgical options which do not require the destruction of brain tissue, although their efficacy has not been conclusively demonstrated.[1]

Surgery

Psychosurgery

  • For patients whose condition does not improve with other medications and treatments, procedures may be the chosen course of treatment.
  • These patients may choose to undergo psychosurgery as a last resort. In this procedure, a surgical lesion is made in an area of the brain (the cingulate bundle). In one study, 30% of participants benefited significantly from this procedure.
  • Deep-brain stimulation and vagus nerve stimulation are possible surgical options which do not require the destruction of brain tissue, however their efficacy has not been established.[1]

Ablative procedures

The ablative procedures used for OCD treatment include:[1]

  • Anterior cingulotomy
  • Capsulotomy
  • Subcaudate tractotomy
  • Limbic leucotomy (combining anterior cingulotomy and capsulotomy)
