Having a diagnosis of dementia does not necessarily mean a person cannot drive. If you have been diagnosed with FAD you have a legal responsibility to inform the Driver and Vehicle Licensing Agency (DVLA) of the diagnosis. The driving insurance company should also be informed.
The Medical Advisory Branch of the DVLA decides whether you can continue to drive using the information provided by you and your GP or hospital consultant. Sometimes it may be necessary to take a free driving test conducted by the Driving Standards Agency.
If you are not able to drive there are other ways of getting around. Many people have found practical solutions such as allowing family and friends to help or arranging an account with a local taxi company.
