Trauma-triggered migraine: an explanation for common neurological attacks after mild head injury

Abstract

✓ This paper reviews the literature on complex temporary disturbances of brain function triggered by mild blows to the head in children, adolescents, and young adults. It consolidates the evidence by which these attacks have been identified as classical or complicated migraines, and provides a historical account of the descriptions and proffered explanations of these attacks. The clinical features and the electroencephalography, angiography, computerized tomography, and cerebrospinal fluid findings of trauma-induced migraine are presented and compared to those of spontaneous migraine. Ideas about the pathogenesis of this condition are related to current thinking on the neurological phenomena of migraine in general.
