Myoclonic seizures can be generalised onset, meaning both sides of the brain are affected from the start, or they can be focal onset, meaning just one side is affected.
What happens during a myoclonic seizure?
Myoclonic seizures are sudden, short-lasting jerks that can affect some or all of your body. They are usually too short to affect your consciousness. The jerking can be very mild, like a twitch, or it can be very forceful. Sometimes if the jerk is very forceful it can make you throw something you’re holding, or make you fall over.
How long do myoclonic seizures last?
Myoclonic seizures usually last for less than a second. However, some people have them in clusters of several seizures over a period of time.
What happens after a myoclonic seizure?
After a myoclonic seizure you’re usually able to get back to what you were doing straight away.
