Suzie2017 as you know my husband is only 60 years. His internal medicine doctor reviewed all of his medications and took him off several of them. He still takes his ALZ meds and I don't think those meds cause the lack of words or understanding. It's part of the disease. In my husband's case he uses words from commercials or signs to fill in the blanks. He is past the not talking because he can't communicate, he just says whatever comes to his head and most times none make too much sense. He is healthy though and so far eats well. The last time I took him to the neurologist he just told me to enjoy his health while it lasts. Agree with Scott and others this disease is so different in every person so it's hard to pinpoint what is caused by ALZ or other conditions or medications. Prayers are my best ally..
