I start taking Zonegran over 2 weeks ago, and my hands and feet are freezing cold. It is not a usual effect of Zonegran, but is, as the case with many new medicines. If you are concerned, you should discuss it with your doctor. Approximately 2 to 2.5 million Americans have epilepsy. As I understand it the gamma knife is primarily used to treat vascular malformations and tumors, and if the seizures are being caused by those things then the gamma knife may help treat the seizures also.
Epilepsy can last a few months, years, or life-long.
It varies among individuals. The tests are done to see where the seizures are coming from and if that area can be safely removed. Most centers perform an EEG recording of seizures and MRI scan and a test of brain function known as neuropsychological testing. These are tests that measure the brain's function. Epilepsy can occur or begin at any age.
