My daughter, Holly, has a severe form of epilepsy. The strong seizures began when she was about 14. During most days, she had one or more seizures. Some were "drop attacks," which caused her to fall backward. She had many bad falls before we got her a wheelchair for her own safety. She also had seizures which were called "grand mal" at the time, where her body went into a convulsion that lasted several minutes, followed by sleeping for hours at a time.
