Amine turnover in migraine.

M Anthony, H Hinterberger

    Proceedings of the Australian Association of Neurologists
    |January 1, 1975
    PubMed
    Summary
    This summary is machine-generated.

    Migraine attacks involve significant changes in vaso-active amine excretion, with lower tyramine and higher serotonin during headaches. Blood serotonin levels also decrease during migraine episodes.

    Area of Science:

    • Neuroscience
    • Biochemistry
    • Pharmacology

    Background:

    • Migraine is a complex neurological disorder.
    • Vaso-active amines are implicated in migraine pathophysiology.
    • Dietary factors, such as tyramine, are suspected migraine triggers.

    Purpose of the Study:

    • To investigate the role of vaso-active amines in migraine.
    • To measure amine levels before, during, and after migraine attacks.
    • To evaluate the potential involvement of tyramine in dietary migraine.

    Main Methods:

    • Collected urine and blood samples from 10 migraine patients.
    • Quantified excretion and blood levels of tyramine, serotonin, noradrenaline, adrenaline, and histamine.
    • Analyzed data for statistically significant changes during different migraine phases.

    Main Results:

    • Significant decrease in tyramine excretion during headache.
    • Significant increase in serotonin excretion during headache.
    • Lower blood serotonin levels during headache compared to headache-free periods.
    • Elevated whole blood histamine during the post-headache phase.

    Conclusions:

    • Serotonin and tyramine excretion patterns change during migraine attacks.
    • The observed changes suggest a role for these amines in migraine.
    • Evidence presented questions the primary role of tyramine in dietary migraine.
