[Migraine or transient ischemic attacks in a patient with essential thrombocythaemia. Treatment with ticlopidine (author's transl)]

Abstract

Ischemic cerebrovascular symptoms occuring in patients with essential thrombocythaemia are usually attributed to platelet or platelet-fibrin emboli. A patient is described in whom transient ischemic attacks (TIA) had some features - namely the presence of headache and the progressive onset of symptoms - unusual for an embolic phenomenon but suggestive of a migrainous event. No further attack occured when the patient was treated by an antiplatelet drug ticlopidine, though platelet count was unchanged. The relationship between platelets, TIA and migraine are discussed.
