A recent UK study (J Neurol Neurosurg Psychiatry 2007;78:363C366) tested the driving ability of 154 patients with Parkinson’s disease, including clinical scores, reaction times, and driving tests in the car. 92 (59.7%) of the Parkinson’s disease patients who participated in the study were older than 65 years, 20 of whom cases (13%) were female, with a mean ability of 67.6 years and a mean driving age of 42.1 years. The mean HY classification was 1.9 (all less than and equal to 3) The results revealed that 65.4% (104 cases, mean 65.4 ± 9.7 years) of the patients were able to continue driving, while the remaining 46 (mean 72.1 ± 9.3 years) had to drive an automatic, or required some modification to the vehicle (e.g. with a brake at the left foot). The ability to drive was significantly associated with disease severity, age, presence of dementia, disease duration, braking reaction time, and driving test scores, independent of the dose of medication and driving age. The study concluded that most of the patients with mild to moderate Parkinson’s disease can drive safely, although of course, automatic gears or some appropriate modifications (e.g., if the patient is right-limb symptomatic, the brakes can be modified to the left foot) would be safer. The combined assessment of clinical tests and in-car driving tests can make a reasonable determination of whether a person with Parkinson’s disease is able to drive safely.
