AI Thread Summary
Post-mortem studies of COVID-19 patients indicate the presence of ischemic lesions and neuro-inflammation, highlighting potential neurological impacts of the virus. Additionally, nearly 90% of EEG studies in these patients show epileptiform discharges, primarily in the frontal lobes, suggesting both functional and structural changes in brain activity. Concerns about long-term effects of COVID-19, including neurological symptoms, are underscored by popular articles discussing the prevalence of long COVID. A participant in the discussion mentions experiencing headaches and dizziness, attributing them to post-COVID symptoms and medication use.

TL;DR Summary
Long COVID is real & measureable.

The largest effect sizes were seen in tests of verbal reasoning, multi-stage planning, and spatial attention.
Participants who had received a positive <COVID> test had a lower global score and this deficit scaled with the severity of initial respiratory illness: There was... also a clear effect for mild but biologically confirmed cases who reported no breathing difficulties.
Post-mortem studies of patients who have died of COVID-19 show evidence for ischemic lesions and indications of neuro-inflammation (Matschke et al., 2020).
...
The changes may be functional as well as structural, with nearly 90% of electroencephalography (EEG) studies conducted in patients with COVID-19 revealing epileptiform discharges, mostly within the frontal lobes (Galanopoulou et al., 2020)

I don't feel dizzy, but did take 2x ibuprofen 200mg tablets for my headache earlier today, which I hope was put down to my post-Covid intense coughing.
 
I've been reading a bunch of articles in this month's Scientific American on Alzheimer's and ran across this article in a web feed that I subscribe to. The SA articles that I've read so far have touched on issues with the blood-brain barrier but this appears to be a novel approach to the problem - fix the exit ramp and the brain clears out the plaques. https://www.sciencealert.com/new-alzheimers-treatment-clears-plaques-from-brains-of-mice-within-hours The original paper: Rapid amyloid-β...
