    Migraine patients exhibit distinct psychophysiological changes before, during, and after attacks. These patterns, including heightened anxiety and pain sensitivity, may predict and help prevent future migraine episodes.

    Area of Science:

    • Neuroscience
    • Psychology
    • Pain Medicine

    Context:

    • Migraine without aura is a common neurological disorder.
    • Understanding the psychophysiological changes associated with migraine attacks is crucial for effective management.
    • Previous research has explored various aspects of migraine pathophysiology, but a comprehensive psychophysiological profile across different attack phases remains to be fully elucidated.

    Purpose:

    • To investigate the psychophysiological patterns in patients with migraine without aura compared to healthy individuals.
    • To analyze changes in psychological and neurophysiological parameters before, during, and after migraine attacks.
    • To explore the potential of these psychophysiological dynamics as predictors for migraine prophylaxis.

    Summary:

    • A study involving 85 migraine patients and 20 healthy controls examined clinical-neurological, psychological (Spielberger, Beck, alexithymia, algesic questionnaire), and neurophysiological (conditional negative wave, nociceptive flexor reflex, trigeminal evoked potentials, heart rhythm spectral analysis, polysomnography) parameters.

  • A characteristic psychophysiological pattern was identified in migraine patients, with synchronous changes in psychological and neurophysiological parameters observed before, during, and after attacks.
  • Key pre-attack findings included increased pathological integration, weakened antinociceptive system activity, heightened anxiety, increased catecholaminergic system tension, elevated trigeminal hyperactivity, and decreased pain tolerance.

    • Impact:

    • The identified psychophysiological dynamics show a tendency towards reversibility after an attack.
    • These dynamic changes could serve as valuable predictors for impending migraine attacks.
    • This research opens new avenues for the development of targeted prophylactic strategies for migraine management.
