Epilepsy and the Corpus Callosotomy


How Effective Is a Corpus Callosotomy?

Corpus callosotomy is successful in stopping drop attacks, or atonic seizures in which a person suddenly loses muscle tone and falls to the ground, in about 50% to 75% of cases. This can decrease the risk of injury and improve the person's quality of life.

What Are the Side Effects of Corpus Collosotomy?

The following symptoms may occur after having a corpus collosotomy, although they generally go away on their own:

  • Scalp numbness
  • Nausea
  • Feeling tired or depressed
  • Headaches
  • Difficulty speaking, remembering things, or finding words
  • Paralysis, weakness, loss of sensation
  • Change in personality



What Are the Risks of a Corpus Callosotomy?

Serious problems are uncommon with a corpus callosotomy, but there are risks, including:

  • Risks associated with surgery, including infection, bleeding, and an allergic reaction to anesthesia
  • Swelling in the brain
  • Lack of awareness of one side of the body
  • Loss of coordination
  • Problems with speech, such as stuttering
  • Increase in partial seizures (occurring on one side of the brain)
  • Stroke
