RESUMEN
INTRODUCTION: Demographic and clinical data were collected from three cross-sectional samples, from the headache and epilepsy clinics according to respective protocols. During structured interviews, we examined the co-occurrence of headaches and epilepsy in children and their families: (1) 172 children from the headache clinic, were questioned for the number and type of epileptic seizures and epilepsy diagnosis. (2) Around 70 children from the epilepsy clinic for the frequency and type of headaches and headache syndrome diagnosis. (3) A total of 149 parents of children with benign childhood epilepsy with centro-temporal spikes (BCECTS) and childhood absence epilepsy (CAE), for the relative frequency of headaches in first- and second-degree relatives. RESULTS: Out of 172, 84 (48.8%) children with headache had a migraine and 60 (34.9%) had tension headaches; 3 children (1.7%) had epilepsy or unprovoked seizures. Migraine and epilepsy, co-occurred in 2/84 (2.3%). Eight out of 70 patients with epilepsy had headaches (11.4%); none had migraine. Around 43% of patients with BCECTS or CAE had a family history of headache, more prevalent in first-degree relatives of children with BCECTS than CAE. CONCLUSION: Contrary to existing literature, migraine and epilepsy, co-occurred infrequently in these highly selected samples. Family history of headache was frequent in patients with BCECTS and CAE, without any significant difference between the two.
