I Have Had A Lot Of Trouble With My Memory.

I have had a lot of trouble with my memory. For example, I will be talking with someone. I have to stop right in the middle of the conversation to try to remember what was the word I was going to use.
I know I know the word, but I can't get it in my useable vocabulary. I blank. This happens to me all the time. I lose things. I lost my keys today. I lost my phone a couple of weeks ago. I lose my keys all the time. I am 62 years old. My mother has dimentia, and I am doing things that she did for years.
