The clinical features of migraine as a manifestation of allergic disease

Abstract

Patients with a clinical history of migraine were evaluated psychiatrically, and by electroencephalography. They were challenged with food antigens by skin-prick test, and abdominal symptoms were evaluated following oral ingestion of food allergens. A significant correlation was found between challenge with specific food allergens and the development of migraine headaches, the appearance of abdominal symptoms and the occurrence of positive skin reactions. Psychiatric abnormalities and EEG alterations were associated with the occurrence of headaches and allergic clinical features. It is suggested that the clinical features of migraine can be explained as a result of release of chemical mediators following antigen-antibody reactions in the brain and other tissues where specific antibodies are localized. The continuous ingestion of the responsible food allergens would account for the raised tissue concentrations of noradrenaline, histamine and other mediators to which the clinical features of migraine are attributed.
