My father has been diagnosed with early stages of Alzheimers. He's 78 and the only symptoms at the moment are very poor short term memory. He still seems to be able to function as normal in other aspects of his life. He does the Daily Telegraph cryptic crossword every day, writes sermons for church etc. My mother hasn't told him of his diagnosis and he just thinks he has a bad memory and is taking Aricept. His poor memory does frustrate him and get him down. I was looking for advice about whether he should know of his diagnosis as I can see benifits in telling him and not telling him. Any help would be appreciated. Thank you in advance
