I am 48. I used to be very smart. I was an excellent speller and excellent with numbers and math. Now I am less smart.

But what I really notice is weird mistakes like alzheimer's. For example, I couldn't remember my sister's name. Sometimes I make spelling mistakes, write down numbers wrong, etc. I never made those kinds of mistakes in the past.

This is especially bad when I'm depressed. Yesterday, a customer asked me a price that I use every day, but I was totally clueless for 30 seconds or so until I remembered again.

I worry a little about a medical problem, but my doctor wasn't concerned about it when I mentioned it a couple of years ago.

Anybody else notice this?
