[Serotonin concentration in the blood of patients with tonic seizures localized in the brain stem].

The authors studied the content of general serotonin in different periods of attacks in patients with tonic attacks of a stem localization. It was possible to demonstrate an increased content of blood serotonin in the initial phase of the attack. During the crucial phase the serotonin content compared to the initial phase, decreases. However, its level compared to the onset level continued to be high. An increase in the serotonin content was accompanied by significant neurotic symptoms and in some cases by psychomotor excitation. The spectrograms of serotonin eliminated from the blood of patients are different by forms and may serve as one of the tests for the establishment of the degree of the disorder.
