Prolactin--a diagnostic aid in cerebral seizures

Prolactin concentration was measured 20 minutes after each seizure in 8 patients with grand mal, 2 patients with complex partial seizures and 5 patients with petit mal seizures. In the group of grand mal and complex partial seizures serum prolactin showed markedly increased levels. After petit mal seizures there was no change in serum prolactin concentration. The possible causes for changes in serum prolactin after a seizure in children are discussed.
