Headache can be triggered by epileptic seizures, either during the seizure or shortly after it. They resolve spontaneously within a few days of the seizure ending. In some types of epilepsy (frontal lobe, temporal lobe, or occipital lobe), headaches after a seizure (post-ictal headache) are quite common – occurring for 40-60% of people.
While an epileptic seizure headache occurs following a seizure, the inverse can also happen. Some migraine patients experience seizures that are triggered by their migraine attacks.
