how can someone live with half a brain
Hemispherectomy One such predictor of success is often the age of the patient. This procedure is almost exclusively performed in children because their brains generally display more neuroplasticity, allowing neurons from the remaining hemisphere to take over the tasks from the lost hemisphere. This likely occurs by strengthening neural connections which already exist on the unaffected side but which would have otherwise remained small in a normally functioning, uninjured brain.[12] In one study of children under 5 who had this surgery to treat catastrophic epilepsy, 73.7% were freed of all seizures.[13]
