[The character of cortico-subcortical relations in neurotic patients (according to EEG findings)].

Electroencephalographic examinations have been carried out in 179 neurotic patients. Five types of the EEG have been identified depending on the nature of cortico-subcortical interrelations. Types 1 and 2 are normal variants; types 3, 4, and 5 are abnormal. It has been ascertained that in patients with hysteria normal EEG types occur less commonly while irritation of the posterior hypothalamus is much more frequent as compared to neurasthenic patients. It has been established that an injury or neuroinfection are responsible for pathologic EEG alterations.
