[Facial hemispasm]

Using methods of clinical, psychometric and electropolygraphic examination 36 patients with facial hemispasm (FH) were studied in the sleep-awakening cycle. The authors describe neurodynamic shifts at both peripheral and supranuclear levels of facial innervation. These shifts were correlated with the severity and side of damage. Different levels of the nervous system, including the brain stem and cerebral non-specific formations, were involved in the pathogenesis of FH.
