I am pretty sure my 78 year old mom has Alzheimer's but gets very defensive and depressed if we mention her memory issues. She won't make an appointment to get an assessment, and I am afraid to make her go or make one for her. So how important is it to have that official diagnosis? I know there is medicine to help, but is it worth forcing her to go and possibly devastating her by the diagnosis not to mention animosity between us. Nor sure what to do.
