Exercise and Epilepsy

Living with epilepsy can be a real balancing act. When epileptic seizures are not well-controlled, one never knows when a seizure might hit. Life can be significantly pinched.
But being active need not be a casualty. According to an April 1, 2010 article on Medscape.com, the American College of Sports Medicine has encouraged those with epilepsy to embark on an exercise program that fits their needs.
The ACSM offered reassurance that in fact seizures are unlikely to happen while exercising, and the more you exercise, the less likely you are to experience a seizure.
