Alzheimer's disease and other dementias cause changes that affect a person's ability to drive a motor vehicle safely. A diagnosis of dementia, however, does not automatically mean that a person is incapable of driving. Some people may be capable of driving safely for some time after the diagnosis, depending on when in the disease progression the person has been diagnosed and the rate the disease progresses. Eventually, however, people with Alzheimer's disease must stop driving, as it will no longer be safe.

Look into special testing to assess the driving abilities of a person with dementia. This could be a driving simulation test and/or a road test, carried out by someone with experience in testing drivers with cognitive problems.

Use the search bar above to find a driving assessment service (such as DriveAble or MARD) in your area. If it is not available, ask a doctor to determine if and when the person is no longer able to drive.
