On Tuesday 27 May, Bob & Joy Graham asked for experience About 4 years ago, I attended a presentation given by the Professor of Psychology at Leeds University, Professor Mindham, (What a splendid name for a Psychologist!). He was reporting on a group of about 300 PWPs, who had been monitored for several years. The objective was to assess driving capability and PD, and was done by regularly measuring the performance of each subject by measuring co-ordination and reaction times on a fairly simple driving simulator. The main conclusion was that in every case when he decided that a person's reactions, etc were at a level where they should be considered unsafe to drive, that person had already made the decision to give up driving. I found that to be a reassuring finding, demonstrating that most PWPs maintain a realistic and responsible attitude to driving. My confidence was slightly dented by one or two of the horror stories which have been mentioned on these pages, but hopefully they are extreme examples. I drive occasionally these days, and only attempt long drives (greater than 20 miles) with my wife and co-driver beside me. After considerable thought, I decided to stay with the manual transmission , because my ability to change gear smoothly. is the first thing that goes when I am sliding into an off period. When properly dosed with my meds, I consider myself to be a normal driver, but I would not even attempt to drive when in the Off condition; it would be totally irresponsible. If I have taken too much Levodopa, I can drive, but it is not an enjoyable activity: I find myself gripping the wheel so tightly that my arthritis plays up, and there is a risk that I will cause dents in the steering wheel! My 'vital statistics' are : Diagnosed 18 yrs ago First symptoms 24 yrs ago Age now: 57 P.S. I can still ride my bike, even when I am 'Off' and it keeps me much fitter Regards, -- Brian Collins <[log in to unmask]>
