Multicenter Study
Peri-ictal and inter-ictal headache in children and adolescents with idiopathic epilepsy: a multicenter cross-sectional study.
Headache in epileptic population ranges from 8% to 15%. The aim of this paper was to study the clinical and temporal characteristics of primary headache comorbidity in idiopathic epileptic children. ⋯ Post-ictal headaches were most frequent (62%). Pre-ictal headaches were less common (30%). Inter-ictal headaches were described in 57.6%. Clear migrainous features were present in 93% of pre-ictal and 81.4% of post-ictal headaches. Inter-ictal headaches meet criteria for migraines in 87%. The association between partial epilepsy and migraine without aura is most common and reported in 82% of our patients with peri-ictal headache and in 76.5% of patients with post-ictal headache.
