[Desynchronization of serotonin, hemodynamic equilibrium and the recurrence of migraine crises]

Haemodynamic balance and the circadian rhythm of plasmatic 5HT were studied in 15 migraine sufferers (common and classic). Haemodynamic imbalance and a clear desynchronisation of the 5HT acrophase was discovered. It is thought that these two elements are correlated and represent a key to the recurrence of migraine attacks.
