Myoclonic epilepsy is a group of conditions involving persistent muscle jerks with abnormal brain wave activity. “Myoclonic” came from the Greek word “myo” which means “muscle” and “clonus” for “twitching”. The brief jerks mostly occur in the facial muscles or limbs. During the seizures, the individual often has partial awareness and feels like he is being jolted with electricity. The irregular jerking usually lasts for around 30 minutes. Myoclonic epilepsy includes juvenile myoclonic epilepsy (hyperlink), progressive myoclonus epilepsy, and Lennox-Gastaut syndrome (hyperlink).
