An epileptic seizure is a period of intense muscle spasms involving many muscles at once. Most seizures last only a few minutes and do not have serious side effects. However, a seizure that continues for longer than several minutes is a medical emergency. There are usually two reasons for a seizure. The first is a temporary issue such as low blood sugar or a concussion. The second is any disease or issue that may cause a seizure for seemingly no reason. Sleep deprivation can result in seizures, as can many neurological diseases.
