[Functional disturbances of the nervous system in the practice of occupational health]

On the basis of a questionnaire survey performed in the group of 80 persons, the author defined how the Occupational Health Service physicians conceive functional disturbances of the nervous system in their daily practice. The survey shows that they are not trained enough to be able to assess this kind of sickness. Their work is hindered by a lack of generally adopted definitions, classification of diseases and methodological guidelines how to define working ability of persons with functional disturbances of the nervous system.
