Concentration issues

Hello, I've been in menopause for approx 10+ years since I had a partial hysterectomy when I was in my mid-40s. Just recently I've been experiencing problems with concentrating and following along with other people speaking. I find myself thinking of things I need to do (grocery shopping, errands, chores, etc.) and then realize I haven't been paying attention to them. I'll ask my neurologist if I can be tested for Alzheimers and Dementia, but is anyone else experiencing this? A co-worker blamed the same type of problem on her just entering menopause. I don't think it's brain fog from Covid because I had Covid ~10 months ago and didn't have this problem then. Could it possibly be menopause? If so, why now and not years ago? Any thoughts or suggestions?
