ESCO reviews this information regularly. It supports learning and does not replace professional medical advice, diagnosis or treatment. Discuss your own care with your healthcare provider.
The seizure
Stiffening may cause a fall. Jerking follows, and breathing can change. These seizures may be generalized or develop from a focal seizure.
Recovery
Tiredness, soreness and confusion may follow. Stay nearby and monitor breathing. Concerning unresponsiveness must not be assumed to be ordinary sleep.
Protect the person.
Time the seizure, clear hazards and cushion the head. Never restrain movements or place anything in the mouth. When safe, gently position the person on their side.
Call 911 for an event exceeding five minutes, another seizure before recovery, breathing or waking difficulties, injury, a seizure in water or a first known seizure. Other emergency circumstances also apply.
If unresponsive and not breathing normally after movements stop, call 911, begin CPR and follow the dispatcher’s instructions.
