1. Hemispherectomy

   Hemispherectomy is a neurosurgical procedure in which a cerebral hemisphere (half of the upper brain, or cerebrum) is removed or disconnected that is used to treat a variety of refractory or drug-resistant seizure disorders (epilepsy). Refractory or drug-resistant epilepsy is defined as seizures that fail to be controlled using 2 or more appropriate anti-seizure medications. About one in three patients with epilepsy have drug-resistant epilepsy and of those, about half of them have focal epilepsy that can potentially be treated with epilepsy surgery. In drug-resistant epilepsy where all or most seizures arise from one hemisphere, hemispherectomy is a highly effective procedure producing seizure freedom in about 80-90% of patients. In addition to controlling seizures and as a result of that, improved development and cognition is also very frequently achieved after hemispherectomy. Most patients who qualify for hemispherectomy already have neurological deficits such as hemibody weakness or loss of vision in one visual field that is opposite to the side of the affected hemisphere. This means that performing hemispherectomy does not add deficits to a new hemisphere in these patients. However, detailed testing is always performed prior to epilepsy surgery in general (including hemispherectomy) to ensure that such procedures would achieve two goals: 1) eliminating or greatly reducing seizures and 2) causing no or minimal deficits that could impair the patient’s functionality.

1. Hemispherectomy

   Hemispherectomy is a very rare surgical procedure where one cerebral hemisphere is removed or disabled. This procedure is used to treat a variety of seizure disorders where the source of the epilepsy is localized to a broad area of a single hemisphere of the brain, among other disorders. It is solely reserved for extreme cases in which the seizures have not responded to medications and other less invasive surgeries. Hemispherectomy is considered the most invasive surgical operation in use today, although not the most dangerous.

1. Hemispherectomy

   A neurosurgical procedure that removes or disconnects the epileptogenic CEREBRAL CORTEX of a hemisphere. Hemispherectomy is usually performed for patients with intractable unilateral EPILEPSY due to malformations of cortical development or brain lesions. Depending on the epileptogenic area in the hemisphere, cortical removal can be total or partial.
