There are two types of seizures:
Focal seizures
Focal seizures are those that come from a single specific part of your brain. You might suffer from focal seizures with impaired awareness, where you’re not conscious of what you’re doing and might make repeated movements or stare into space.
Or you might get focal seizures without loss of consciousness. In this case, you remain aware of your surroundings but might experience sensory changes and spontaneous movement.
Generalized seizures
Generalized seizures involve your whole brain. Absence seizures (previously called petit mal seizures), which tend to affect children, are one type of generalized seizure. Tonic seizures, atonic seizures, clonic seizures, and myoclonic seizures are types that cause various forms of twitching or other movements.
Tonic-clonic seizures (previously grand mal seizures) cause the most dramatic form of epileptic seizures. They can trigger an immediate loss of consciousness, make your body stiffen and shake, and may cause tongue-biting and loss of bladder control.
