Acute toluene poisoning. Electroneurophysiological and vestibular investigations

Neurophysiological studies were carried out in six female workers of an electromechanical works after accidental exposure to toluene vapours. Electroencephalographic abnormalities and vestibular hyporeflexia were detected immediately after the accident. Six months later the EEG changes were still present, while vestibular findings were found to be markedly improved. Results of this study provide further evidence of the diagnostic value of vestibular investigations after toxic exposure to toluene.
