Primary care physicians are frequently involved in cases in which they must decide if a patient with dementia should stop driving. The decision is complex, and there are no firm clinical guidelines available. We examined the results of a number of patients who have undergone assessment in our Driving Assessment Clinic, to determine if any of our findings correlated with the diagnosis of dementia. If any associations exist, recommendations may be possible to assist PCPs in making the decision to have patients stop driving, even if full formal testing cannot be done
