"Worried Well" Planning for Alzheimer's

I'm 66 years old, with a nursing background, and a strong family history of Alzheimer's on the maternal side-mother, two aunts, grandmother. Over the past several years, I've noticed some worrisome problems with my memory.
I don't want to get a formal evaluation at this time, I'm not sure how I would handle the news; also I would like to delay my younger siblings knowing as long as possible, if it turns out to be Alzheimer's. And, of course, it may turn out that these are normal "aging process" symptoms, and just need to be dealt with in a practical way.
I would, however, like to get some support from those in similiar circumstances, or those who have a diagnosis of early alzheimers. I know it is possible to have years of independent functioning after this diagnosis. Any suggestions on coping with memory loss
(such as using pill containers), daily calendar, etc., would be greatly appreciated. Also, I'd be happy to share any support or advice I could give. (My mother is now deceased, and I helped with her care, and she had a fairly good quality of life at home until she died, because my father was able to care for her, and hire good help to share in her care. I know this isn't possible for everyone.) Thanks in advance, and blessings to everyone dealing with this terrible disease.
