1. A surgical procedure in which one hemisphere of the brain is removed or disconnected from the other.
Usage: medical; typically performed to treat severe epilepsy or other neurological conditions in children

Examples

• The neurosurgeon recommended a hemispherectomy to control the patient's intractable seizures.
• Hemispherectomy is sometimes considered when seizures originate from one hemisphere and cannot be managed with medication.
• Children who undergo hemispherectomy may experience remarkable neuroplasticity, allowing the remaining hemisphere to assume many lost functions.
• The decision to perform a hemispherectomy is made only after other treatment options have been exhausted.
• Recovery from hemispherectomy requires extensive rehabilitation and monitoring.
