- reaction time;
- ageing process;
- mental test score.
Reaction time was studied in 103 subjects with idiopathic parkinsonism and 144 without. Central processing time, as measured by the response to a warning, had a component which could be explained by the presence or absence of parkinsonism, but not by the ageing process, a mental test score, or consumption of exogenous substances. Depression did not influence the efficiency of response. Cigarette smoking and anti-parkinsonian medication were associated with greater efficiency.
