Ictal headache (Headache and Epilepsy) | |

Specialty | Neurology |
A headache is often present in patients with epilepsy. If the headache occurs in the vicinity of a seizure, it is defined as peri-ictal headache, which can occur either before (pre-ictal) or after (post-ictal) the seizure, to which the term ictal refers. An ictal headache [1] itself may or may not be an epileptic manifestation. In the first case, it is defined as ictal epileptic headache [2] or simply epileptic headache.[3] It is a type of pain seizure that can remain isolated or be followed by other manifestations of the seizure.[3] On the other hand, a ictal non-epileptic headache is a headache that occurs during a seizure but it is not due to an epileptic mechanism. When the headache does not occur in the vicinity of a seizure, it is defined as inter-ictal headache. In the case it's a disorder separate from epilepsy, it's a comorbidity.
