Genetics of migraine and migraine accompagneé: a study of eighty-one children and their families.
Eighty-one patients suffering from childhood onset migraine and their families were investigated for familial prevalences of epileptic seizures and migraine. The incidence of epileptic seizures was not increased above the epidemiological risk. - In all, migraine is largely inherited from maternal ascendents, irrespective of the sex of the index case. Clinical subtypes of migraine ("non-focal migraine" and migraine accompagnée) are not accompanied by respectively increased familial prevalences. - Onset of migraine is earlier in patients with a higher familial impact. These findings are discussed in context with a proposed multifactorial pathogenesis of migraine.
