title: Trigger factors in childhood migraine: a clinic-based study from eastern India.
abstract: Literature on triggers of childhood migraine is sparse. This study was carried out in 200 children (7-15 years) with migraine from a metropolitan city in Eastern India, both retrospectively and prospectively, with headache diaries to note the incidence of various triggers. In the retrospective study, triggers could be identified in 94% of subjects while in 100% of children in the prospective part of the study more than one trigger could be identified. Most migraine triggers identified were environmental (sun exposure, hot humid weather, smoke and noise) and stress related (school stress mostly). Quite often these operated concurrently to precipitate individual migraine attacks.
