There isn’t much you can do to stop a seizure once it starts but you can help protect someone from harm during one.
Focal seizures -The person with epilepsy not be aware of what's happening. He/she might seem to zone out or stare at nothing as the seizure becomes complex. When it's over, they won’t remember a thing.
Generalized seizures - The most well-known type falls in this group, better known as a grand mal seizure. These are frightening to watch and can be an emergency.
Any generalized seizure can be dangerous because the person is unaware of the surroundings and can't protect herself from harm. The uncontrolled thrashing raises the chances of injury. This type is most likely to result in a trip to the emergency room.
It's all about taking precautions. You’re most likely to need it for a generalized tonic-clinic seizure.
Remember, this type probably isn’t an emergency, although it may look like one. Milder seizures, like a bit of staring or shaking of the arms or legs aren’t emergencies either. Still, you should gently guide the person away from threats, like traffic or stairs.
