If you or your family member experience extreme seizures due to epilepsy, in rare cases your doctor may recommend surgery (corpus callostomy) to cut the fibers (corpus callosum) between the brain’s two hemispheres to reduce seizures. While the corpus callosum helps the brain share information, it can also contribute to the spread of seizures in people with epilepsy.
Corpus callosotomy is a procedure that cuts these fibers to prevent the spread of seizures from one side of the brain to the other. This procedure typically doesn’t stop seizures from occurring, but seizures usually become less severe because they can’t spread to both hemispheres.
Corpus callosotomy is usually only used for people with the most extreme forms of epilepsy, such as:
- Seizures characterized by drop attacks.
- Seizures that spread to both brain hemispheres.
- Seizures that don’t respond well to medication.
To help decide if surgery is right for you, epilepsy specialists in the Sutter network may order tests and imaging. These may involve brain scans, memory tests and an EEG to record your brainwave activity.
