[Autonomic nervous changes in combined exposure to lead and arsenic]

The characteristic features of the clinical and functional indicators in the early stages are outlined. The impression is that the subjective feelings are being overlapped and objectified by the neurologic status. A considerable number of non-specific reactions with a tendency for generalization are established. It is presumed that in the latent period, the functional changes in the nervous system forerun those in the clinical course and blood. Emphasis is laid on the significance of the astheno-vegetative syndrome and some neurological signs for the early diagnosis.
