Salicylate prophylaxis in migraine.

Abstract

46 migraine patients and 4 patients suffering from "nonmigrainous" vascular headache were treated with 250 mg salicylate daily for 2 months. Platelet aggregability before and under treatment was measured in all patients and in 10 controls. The results confirm platelet hyperaggregability in migraine patients and a reduction of aggregability under salicylate out provide no evidence of any significant clinical improvement, thus falsifying the hypothesis of migraine as a platelet aggregation disorder.
