Blood and migraine

ABSTRACT

Many are the theories regarding the physiopatolhogy of migraine and some blood alterations found in migranous patients still await explanation. Migraine has already been considered a "platelet disorder", and drugs affecting platelet aggregation have always had a place in migraine therapy. Chronic use of heparin and warfarin has been reported to improve the frequency and intensity of migraine attacks. The present work is a review of haematologic alterations in migraine, discussing the possible role of platelets and basophils on the genesis and perpetuation of attacks in this chronic and often incapacitating headache.
