Abstract

The aim of this study was to evaluate the effects of chronic exposition to neurotoxic solvents in a group of laundry operators by means of Vocal Reaction Times (VRTs) measurements. A group of normal subjects, matched for age and educational level, constituted the controls. Vocal Reaction Times were measured by a device that presented to each subject a sequence of words on a computer screen, acquired the acoustic signal and measured VRTs and durations. During the test a random sequence of words was presented to the subjects; the protocol consisted of two immediate reading task and two delayed reading tasks. The test was performed using concrete and meaningless words. Statistical analysis showed that reaction times measured on the acoustic signals were longer for the exposed group than for the controls. The differences between durations were significant for the delayed reading tasks using concrete words and for all tasks using meaningless words. These findings suggest that this technique may be considered a useful tool for the assessment of the preclinical alterations of CNS in the monitoring of individuals chronically exposed to neurotoxic solvents.
