What is a Myoclonic Seizure?
According to the Epilepsy Foundation:
Myoclonic (MY-o-KLON-ik) seizures are brief, shock-like jerks of a muscle or a group of muscles. “Myo” means muscle and “clonus” (KLOH-nus) means rapidly alternating contraction and relaxation—jerking or twitching—of a muscle. Usually they don’t last more than a second or two. There can be just one, but sometimes many will occur within a short time. They occur in a variety of epilepsy syndromes that have different characteristics. During a myoclonic seizure, the person is usually awake and able to think clearly.
My Myoclonic Seizures
At this point, it is important to remember that epilepsy is a very individualistic condition. What happens when I have a seizure may be radically different from another person with epilepsy. Time of day is important for me. Most of my myoclonic seizures have occurred late at night or really early in the morning. To anyone else, it would seem like my jaw is twitching. If the myoclonic seizures do not stop, often they progress into a tonic-clonic seizure (type of seizure normally shown in tv shows and movies). I can tell when this is going to happen because I gradually lose the ability to think clearly, speak or even walk. I have always considered my myoclonic seizures to be a warning of a potential tonic-clonic seizure.
