I'm neither a researcher or doctor, but I've seen numerous articles that describe this. Anecdotally, I've had multiple people (acquaintances and family) suffer from neurological effects.
Thanks for finding some papers but I’m not sure they support OP’s claim.
I’ll admit I don’t understand the first one. Somehow they’re claiming covid causes Parkinson’s and Alzheimer’s? How can we know that after less than two years?
The second one is clear to mention “ Most people infected with SARS-CoV-2 virus will have no or mild to moderate symptoms associated with the brain or nervous system. However, most individuals hospitalized due to the virus do have symptoms related to the brain or nervous system, most commonly including muscle aches, headaches, dizziness, and altered taste and smell.”
So They are claiming an effect but not for mild cases like OP said and not really claiming brain damage anyway.
