ABSTRACT
In Chiari 1 Malformation (CM1) the most frequent symptom is exertional headache, but other headache types have been reported, such as migraine. This cross-sectional study is aimed to examine the prevalence of migraine in a group of CM1 headache patients and to compare clinical-demographic characteristics between migraine and non-migraine patients. 427 adults were enrolled at the multidisciplinary Chiari Center in Torino. 230 headache patients were classified, based on radiological criteria. Frequencies (absolute/percentage values) were calculated in the whole sample for migraine presence (with and without aura), gender, age, radiologic phenotypes and headache clinical characteristics. The association between CM1 diagnosis and headache characteristics (independent variables) and migraine diagnosis (dependent variable) was estimated by logistic regression models. Seventy-eight patients (67 females) out of 230 presenting headache had a migraine (34%), 44/78 (56%) with aura; in 58/78 (74%) migraine was comorbid with secondary headache attributable to CM1. Migraine prevalence in patients with isolated CM1 (52/120, 43.3%) was higher (p = 0.0016) than in all the other patients (26/110, 23.6%). Although migraine was prevalent in females (86%; 61 femalemale ratio), age classes and gender were not risk factors for migraine at multivariate analysis, while migraine was associated with isolated CM1 phenotype (OR = 2.6). This study shows a high prevalence of migraine in CM1 patients and a significant association between migraine and isolated CM1. In patients with radiological evidence of CM1, particularly in the absence of neurological signs, a careful headache clinical characterization, according to the International Headache Society criteria, may be advised.
