Driving with Parkinson’s disease carries certain risks and requires caution to avoid accidents. Some of the main reasons why driving with Parkinson’s disease is a safety risk include the following. Slow and clumsy movements The core symptom of Parkinson’s disease is motor slowing, and the act of driving requires adequate motor dexterity and responsiveness, especially in certain emergency situations. Some patients may not be able to cope with dangerous situations while driving, so the risk is higher. Patients with Parkinson’s disease who have severe motor impairment should avoid driving. Drowsy episodes Car accidents involving people with early Parkinson’s disease driving have been reported internationally. Investigators found that the motorist had a mild condition and was still relatively agile, so he should not have been unable to control the vehicle. The driver said that due to the long-term medication, he was particularly sleepy while driving and could not keep his eyelids open, and that he had slept a lot at night but was still very sleepy during the day and had an uncontrollable sleepiness. Hypotension The dopaminergic drugs currently in common use for anti-Parkinson’s disease have a hypotensive effect, which may cause asymptomatic upright hypotension to worsen into symptomatic hypotension. In severe cases of upright hypotension, there is a sudden loss of consciousness, limb weakness, falling, and “syncope”. If this happens while driving, the danger is self-evident. Patients with moderate to severe cases of upright hypotension should avoid driving. Parkinson’s disease is not only characterized by motor impairment, but also by a decline in intelligence, from mild intelligence in the early stages to dementia in the middle and late stages. One is a decrease in the ability to analyze, judge and understand, and the other is a decrease in the ability to recognize and remember time, space, location and images. This can be manifested in the form of getting lost easily or not being able to judge the road conditions, or not knowing how to deal with emergencies, etc., and being overwhelmed. Psychiatric symptoms such as hallucinations and delusions A small number of people with Parkinson’s disease may have psychiatric symptoms such as hallucinations and delusions, which can lead to misjudgment and misbehavior of Patients, and the risk is high. In such cases, you need to see a specialist as soon as possible, and driving is contraindicated. The reduced driving ability of Parkinson’s disease patients is related to endogenous factors such as the progression of Parkinson’s disease on the one hand, and may also be related to exogenous factors such as adverse drug reactions on the other. Both aspects should be carefully identified and analyzed, and actively dealt with in order to drive safely, avoid danger and enjoy a good life.
