[Current views on the pathological changes in the nervous system of persons chronically exposed to organic solvents].

On the basis of a review of the pertinent literature the author discusses pathological changes present in subjects with chronic exposure to organic solvents. The author describes the most frequent symptoms and signs constituting clinical syndromes--neurosis-like, encephalopathic and polyneuropathic. A number of observations of subjects with long-term exposure to benzine and benzene homologues are quoted. Diagnostic investigations of the nervous system are described which are used in cases of suspected chronic poisoning with organic solvents.
