Platelet aggregability in migraine.

J R Couch, R S Hassanein

    Neurology
    |September 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Migraine patients exhibit heightened platelet activity, a condition known as platelet hyperaggregability. This finding may explain the increased risk of stroke and heart attack in individuals with migraine.

    Area of Science:

    • Neuroscience
    • Hematology

    Background:

    • Migraine is a complex neurological disorder.
    • Cardiovascular comorbidities are reported in migraine patients.

    Purpose of the Study:

    • To investigate platelet aggregation in migraine patients.
    • To determine if platelet hyperaggregability is linked to migraine severity or associated symptoms.

    Main Methods:

    • Optical density methods were used to measure platelet aggregation.
    • Adenosine diphosphate (ADP) was used as an agonist.
    • 46 migraine patients and 46 matched controls were included.

    Main Results:

    • Migraine patients showed significantly increased platelet aggregation (hyperaggregability) compared to controls.

    Related Experiment Videos

  • A lower threshold for platelet-release reaction and increased platelet stickiness were observed in migraineurs.
  • Platelet hyperaggregability did not correlate with migraine severity or neurologic symptoms.

    • Conclusions:

    • Platelet hyperaggregability is a feature of the migraine syndrome, independent of headache occurrence.
    • This hyperaggregability may contribute to the elevated risk of stroke and heart attack in migraine patients.
