    Migraine patients did not show increased platelet aggregation with ADP. However, the platelet aggregate ratio (P.A.R.) was significantly different, suggesting potential hyperaggregability in migraineurs.

    Area of Science:

    • Cardiovascular Science
    • Hematology
    • Neurology

    Context:

    • Migraine is a common neurological disorder.
    • Previous studies suggest a link between migraine and cardiovascular events.
    • Platelet function is crucial in hemostasis and thrombosis.

    Purpose:

    • To investigate platelet aggregation in migraine patients.
    • To compare platelet function between migraine patients and healthy controls.
    • To explore potential mechanisms linking migraine to cardiovascular risk.

    Summary:

    • Platelet aggregation in response to adenosine diphosphate (ADP) was measured in 24 migraine patients and 15 controls using optical density methods.
    • No significant difference in ADP-induced platelet aggregation was observed between migraine patients and controls.

  • However, the platelet aggregate ratio (P.A.R.) measured by the Wu and Hoak method showed a significant difference, indicating potential platelet hyperaggregability in migraine patients.

    • Impact:

    • The findings suggest that while general platelet aggregation may not be elevated, specific platelet function alterations (P.A.R.) might exist in migraine patients.
    • This potential platelet hyperaggregability could contribute to the increased risk of stroke and heart attack observed in migraineurs.
    • Further research is warranted to elucidate the precise role of platelet dysfunction in migraine pathophysiology and associated cardiovascular risks.
