I’ve noticed my mom’s cognitive function has gotten worse since she got covid. She can’t follow conversations as easily, she forgets things (a few days ago she left the stove on), and she’s paranoid the neighbors have bugged our house. She’s never been a very clever person, but yeah it’s worse. Granted, my grandmother had early onset dementia and my grandfather died of something brain related (cancer? Aneurysm? I don’t remember) but I’m hoping those aren’t it.
