Many people with Parkinson’s disease have cars in their homes and drive, and some even have careers that are related to driving. We know that with Parkinson’s disease, the limbs are not subject to self-controlled movement, so it is definitely not possible to drive. But then patients ask if they can drive if they are well controlled by medication. According to a study by neuroscientists at the University of Glasgow in the UK, there are certain risks associated with driving in Parkinson’s disease patients that need to be addressed carefully to avoid accidents. Parkinson’s disease patients driving there are safety risks for the following reasons. 1, slow and clumsy movements Many people with Parkinson’s disease have symptoms of motor slowing, and the act of driving requires sufficient motor dexterity and responsiveness, especially in certain emergency situations. Some patients may not be able to cope with dangerous situations during driving, so the risk is higher. For Parkinson’s disease patients with severe motor impairment, driving should be avoided. 2, sleepy episodes Internationally, there have been reports of early Parkinson’s disease patients driving a car accident, investigators found that the motorist’s condition is relatively mild, the movement is still relatively flexible, should not be unable to control the vehicle. The driver said that due to long-term medication, especially sleepy while driving, eyelids can not be opened, obviously sleep a lot at night, but during the day is still very sleepy, there is a kind of sleepiness can not be suppressed. 3, hypotension Currently commonly used anti-Parkinson’s disease drugs in dopaminergic drugs have a hypotensive effect, may lead to asymptomatic upright hypotension aggravated into symptomatic hypotension. Upright hypotension is serious when there will be a sudden loss of consciousness, limb weakness, fall, “fainting” phenomenon. If this happens while driving, the danger is self-evident. Patients with moderate to severe upright hypotension should avoid driving. 4, intellectual decline, decreased judgment Parkinson’s disease not only has movement disorders, there may also be intellectual decline, the early manifestations of a mild decline in intelligence, and even accompanied by dementia in the middle and late stages. Intelligence loss is mainly manifested in two aspects, one is the decline in the ability to analyze, judge and understand, and the other is the decline in the ability to recognize and remember time, space, location, images and so on. The performance in the driving is easy to get lost or the road condition judgment is unclear, or do not know how to deal with the taboo situation, etc., the performance of the overwhelmed. 5, hallucinations and illusions and other psychiatric symptoms A small number of patients with Parkinson’s disease may have hallucinations, illusions and other psychiatric symptoms, which can lead to the wrong judgment and misbehavior of Parkinson’s friends, the risk is high. In such cases, it is necessary to go to the hospital as soon as possible to find a specialist for diagnosis and treatment, and at the same time, driving is prohibited. To summarize, the reduced driving ability of Parkinson’s disease patients is related to internal factors such as the progression of Parkinson’s disease on the one hand, and may also be related to external factors such as adverse drug reactions on the other. Both aspects should be carefully considered and actively addressed to avoid dangerous driving and enjoy a better life.
