Characteristics of Headache Associated with Intractable Partial Epilepsy

Abstract

We confirm an association between focal epilepsy and HAs, including migraine without aura. This is true for both TLE and ETE. PIHA and even prodromal HA may be related to the epileptic discharge and may have lateralizing value. This association is not recognized by the current International Headache Society (IHS) classification. The presence of HA and migraine is not related to the underlying epileptogenic pathology except in patients with AVMs.
