Drivers with mild to moderate Parkinson's disease may be at higher risk of getting into a car accident when it's foggy. Researchers had patients go through a driving simulation test under good conditions and then in foggy, low visibility conditions. According to the journal Neurology, 76 percent of those with Parkinson's were unable to avoid a simulated crash.
While this disease is known to affect movement, the ability to see contrast and to process visual information quickly also seem to be compromised.
The findings ..even those with mild Parkinson's should be aware of their increased risk for accidents when driving in low visibility.
