Hi Purtycat,
I also have Alzheimer’s and agree what everybody else has said and even do exactly the same thing as Clive and write down all my questions to the doctor, what I also do is to keep a detailed Daily Diary of how the illness is affecting me day to day no matter how insignificant it might seem then I give it to my doctor to see how I have been in-between visits.
You also have every right to ask for a scan as personally I feel that to much valuable time is wasted with all the preliminary tests in the UK instead of going directly to the source of the problem, I was more fortunate as the moment I went to my doctors with my memory concerns after just one examination she almost insisted that immediately had a scan even though she wasn’t so sure that I had AD but the scan proved I had Mixed dementia with AD and from that very moment she put me onto Aricept which is helping me immensely.
Good luck and don’t let the evaluation test make you anxious
