Demographic, clinical and comorbidity data in a large sample of 1147 patients with migraine in Mexico City

The objective was to identify the sociodemographic and clinical characteristics of a large sample of patients with migraine in Mexico City. This cross–sectional study was performed in two tertiary centers in Mexico City and affiliated hospitals. We evaluated the presence of migraine through a standardised interview according to the criteria of the International Headache Society. We studied 1147 patients. The mean age was 37.1±13.6 (6–77) years. Nine hundred and twenty one patients were female (80%). The age of onset of migraine was 19.4±10.3 (1–69) years. Six hundred and four patients had migraine with aura (53%) and 543 without aura (47%). The female/male ratio was 4:1. One hundred and forty–seven patients had cardiovascular problems (13%), 72 had neurological problems (6%), 233 had gastrointestinal problems (20%) and 323 had psychiatric problems (28%). In this study we described the clinical characteristics of a large sample of patients with migraine in Mexico City. Our sample has similar characteristics to other countries.
