My mother is in the early stages of Alzheimer's disease, and it has been fascinating to watch what has happened so far. Mots of her life she has been neurotic which stemmed from being reared by emotionally distant parents, depression, and who knows what all. Like her father she had a photographic memory which has not served her well since she could recall in great clarity all of the subtle abuses of her childhood and then a marriage to someone with his own emotional issues and a tendency to emotional abuse as well. She has had a tough time of it, and it showed. What has happened as she has slipped into Alzheimers and lost these old memories is that she has grown happier. A lot of the emotionally disturbing incidents of her life have been forgotten with the result that she has to some extent been liberated from the burden of the past, and it has made her freer. I don't have any illusions about the ultimate devastation of her disease, but for the time being anyway it has given her a measure of peace in her life - a little blessing.
