Alzheimer's Disease is a world of uncertainty for both the person affected and the family members.  It's important to create moments of joy within that disease and with that senior.  Alzheimer's and dementias affect each person differently, some people have personality or behavioral changes, some lose brain functioning at a faster rate, etc.; their world becomes different.  It is important for family members to pay attention and learn where their loved one is at.  This is not an easy task for family members because the senior's memory maybe affected to where they no longer recall their wife or that they have children, etc.  If we try to correct them, it causes more confusion, anger, sadness or depression for the senior.  Try to put yourself in "their world"....  I once stood in front of a mirror with a lady affected by Alzheimer's and she said "who's that old lady?"  Instead of me saying that's you (since she did not recognize herself), I merely said "I'm not sure exactly, but it's a good thing we are two good-looking ladies."  In her mind, she was in her mid-30s and could recognize herself in an old picture of when she was in her 30s, but if you showed her a picture of herself today, she didn't recognize herself.  Another lady was taking all her clothes and other belongings and gathering them up and putting them into piles, stating she was getting ready for a garage sale.  Instead of telling her it was the middle of winter and she wasn't having a garage sale, I started a conversation by asking her what she was going to buy with her garage sale money.  She said a new car and some new clothes, so we talked about cars and shopping while I helped her "decide what goes and what stays".  We had a great conversation and a fun time.  It is difficult for family members to join in mom or dad's world because it is not "our reality."  But it is their's.  It's our turn to help create memories of joy.  If their thoughts or actions are not physically harming to themselves or others, then just try to roll with where they are at.  Correcting them or trying to bring them to "our reality" will only cause emotional anguish.  The article, "Finding Moments of Joy Helps Alzheimer's Patients" gives additional tips on how to create moments of joy.
