Hi I have been answering TP threads on dementia driving since March 2005 ad nothing seems to change I have also been in more battles with bureaucrats Field Marshal Montgomery.
I have attached two pages of my assessment in 2013 obviously it may have changed now but it will give you some idea of what to expect It won’t be easy considering you Driving future is at stake but if your confident its shouldn’t be a problem
The driving assessment can confirm your practical driving ability and may be useful if DVLA are making medical inquiries. ... The Assessment Centre Team will consider all aspects of driving including medical fitness, vision, awareness, reactions and decision-making as well as physical ability to operate the controls.
hopfully you will find it helpful
