Dementia and driving
Driving involves completing several tasks, often simultaneously (such as braking and steering). These tasks require several physical and cognitive attributes, including:
Good judgment, planning, and decision-making abilities.
The ability to focus.
Quick reaction times.
Coordination.
Adequate muscle strength.
Good range of motion in the upper body (upper trunk, shoulders, and neck).
Good vision and hearing.
Older drivers diagnosed with dementia (including Alzheimer disease) often have poor judgment, impaired memory, and slower reaction times, which is a dangerous mix when driving.
Even when dementia is in its early stages, it can affect driving in several ways:
Reduced reaction time.
Poor hand-eye coordination.
Judging the speed and distance of other cars is reduced.
Remembering directions becomes harder.
Signs that your driving may be affected if you are diagnosed with dementia, include:
Becoming disoriented or lost whilst driving in familiar areas.
Forgetting the purpose of your trip.
Telling the difference between left and right.
Having difficulty making quick decisions at intersections or busy roads.
Driving through Stop/Give Way signs or traffic lights without giving way.
Unexplained dents and scratches on your car.
Slower reaction times and difficulty using the brake, accelerator or steering wheel.
Mixing up the brake and the accelerator.
Mood changes when driving – some previously calm drivers may become angry or aggressive.
If you notice any of these signs developing, it is important to notify your doctor or health professional if you have concerns and regularly monitor your ability to drive.
These signs may become worse until you will eventually need to stop driving. This can be a very difficult experience especially for those living in regional areas, so it is important to start planning alternative transport options early to maintain your independence, freedom and social contacts. More information on this topic can be found in the Getting around without a car section.
There are several services and organisations that provide support and assistance to people living with dementia and their families, Dementia Australia provides further detail on the support and information available.
