Or certain facial muscles might twitch. Speech may become slurred, incoherent, or unusual during the seizure. The person's vision might be affected temporarily. Or she might feel tingling throughout one side of her body. It all depends on what part of the brain is experiencing the seizure.
Generalized seizures involve electrical disturbances that occur all over the brain at the same time.
Consciousness is affected in some way. The person may look like she's daydreaming. She may stare off into space, even when you're calling her name, or she may pass out. Her muscles may stiffen and the person may experience sudden jerking motions, such as flinging her arms outward. Or she may suddenly go limp and slump down or fall over.
