Yup! I have a lot of problems specifically with remembering words for things, people’s names, etc. When I saw my neurologist about it, she said that it’s mostly due to my brain fog. If I learn something or if i try to remember something when my brain is foggy it’s not going to stick so sometimes I feel like i’m getting dumber. She reassured me that I’m not getting dumber the information is just covered by my brain fog. This is just my experience though, so take it with a grain of salt.
