[Facial paraspasm].

Thirty-two patients with facial paraspasm were subjected to comprehensive examination with the use of psychometric and electropolygraphic methods, with the brain awake and asleep. On the basis of the results obtained the author considers clinical differential diagnostic criteria, as well a possible neurodynamic substrate of the above syndrome. Many levels of the nervous system, particularly nonspecific formations of pontomesencephalic portions of the brain stem closely linked with subcortical and rhinencephalic structures, are involved in ensuring this substrate.
