My partner has had symptoms of possible dementia for the past year and a half, getting numbers and words wrong and constantly forgetting words. He is 69 and his dad had early onset Alzheimer's. I finally got him to see a memory nurse and he did poorly in the tests. Shortly after we arrived home we had a call from the nurse who said he had consulted someone else and because of his poor test results he shouldn't be driving at least until he has had a diagnosis after a brain scan in a month's time. My partner was furious and said he can drive perfectly well and now won't go for the brain scan. He is very stubborn. Any suggestions on what to do?
