Ictal headaches are headaches associated with seizure activity. They may occur either before (pre-ictal) or after (post-ictal) a seizure and in rare circumstances during a seizure. Many cases of ictal headache may be misdiagnosed as migraine with aura or even cluster headache. However while these conditions usually involve just one side of the head (are unilateral) an ictal headache may be centrally situated or cover the entirety of the head.
