Intermittent hypoendorphinaemia in migraine attack.

E Baldi, S Salmon, B Anselmi

    Cephalalgia : an International Journal of Headache
    |June 1, 1982
    PubMed
    Summary

    Migraine sufferers have lower beta-endorphin levels during attacks and chronic headaches. This may relate to pain, autonomic dysfunction, and mood changes in migraine.

    Area of Science:

    • Neuroscience
    • Endocrinology
    • Pain Management

    Background:

    • Migraine is a complex neurological disorder.
    • Endogenous opioid peptides, like beta-endorphin, play roles in pain and mood regulation.
    • Dysregulation of neurotransmitter systems is implicated in headache disorders.

    Purpose of the Study:

    • To investigate beta-endorphin levels in plasma of migraine patients.
    • To compare beta-endorphin levels during migraine attacks versus free periods.
    • To assess beta-endorphin levels in chronic headache sufferers.

    Main Methods:

    • Radioimmunoassay (RIA) method was used to measure plasma beta-endorphin.
    • Plasma samples were collected from migraine sufferers during attacks and in remission.

    Related Experiment Videos

  • Control subjects with no history of headaches were included for comparison.

    • Main Results:

    • Significantly decreased beta-endorphin levels were observed in plasma during migraine attacks.
    • No significant difference in beta-endorphin levels was found during free periods in migraineurs.
    • Chronic headache sufferers showed significantly lower beta-endorphin levels compared to controls.

    Conclusions:

    • Hypoendorphinaemia (lowered beta-endorphin) may be a contributing factor in migraine pathophysiology.
    • Reduced beta-endorphin could influence pain perception, autonomic functions, and hedonic capacity in migraine.
    • Impaired modulation of monoaminergic neurons by opioid peptides might lead to neurotransmission imbalance in headache disorders.
