[Some issues regarding the use of electroencephalography and brain evoked potentials in occupational medicine].

On the basis of the literature data, the practical value of electroencephalography (EEG) and tests of brain evoked potentials, particularly visual evoked potentials (VEP) and somatosensory evoked potentials (SSEP) in the diagnosis of occupational diseases of the nervous system is discussed. Electroencephalographic changes and the results of the evoked potential tests performed in persons exposed to organic solvents and heavy metals are analysed. The author postulates how the research in this field should be oriented and stresses the need to incorporate the method of evoked potentials into diagnostic procedures, especially in the case early symptoms of the nervous system dysfunction induced by occupational factors.
