Аннотация
Epilepsy and headache are two chronic disorders that are characterized by recurrent attacks, but the relationship between them is not completely understood. Using a structured questionnaire, we investigated the prevalence of headache during the previous year in a homogeneous group of 100 patients with mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS). The control group consisted of 100 age-matched individuals who were randomized from a nationwide Brazilian headache database. There was a significantly higher prevalence of headache (92%) among the MTLE-HS patients when compared with the controls (73%; p=0.001). Chronic daily headache (CDH) was significantly associated with MTLE-HS (OR 6.1, CI 95% 1.7-22, p=0.005). We did not find any association between the diagnosis of migraine or tension-type headache and MTLE-HS. This study showed that MTLE-HS increases the likelihood of a headache diagnosis. In addition, CDH was more prevalent among the MTLE-HS patients, which supports a common pathophysiological mechanism for epilepsy and headache.
