[Discrimination between epileptic and non-epileptic seizures using defined prolactin studies].

Prolactin blood levels (HPRL) increase within 20 minutes postictally after generalized epileptic, especially generalized tonic-clonic seizures and return to normal values within one hour. Elevated HPRL levels were also observed after complex partial seizures, but usually in less extent, exceeding normal ranges only slightly. Therefore baselin HPRL measurements are necessary for estimation of spontaneous fluctuations in comparison to changes after seizures. Unchanged PRL levels after attacks do not support their epileptic origin. Rage attacke showed no clear pattern of PRL changes.
