Original articleParkinson's disease and solvents: Is there a causal link?

We report here on chronic neurological impairment in three car painters with constant occupational exposure to organic solvents. All had a clinical presentation of Parkinson's disease and, in all cases, SPECT DaTscan brain imaging, using 123I-FP-CIT, showed bilateral reduction of tracer uptake in the basal ganglia, evidence of dysfunction at the dopaminergic terminal.
