COVID-19 infection associated with increased risk of new-onset vascular dementia in older adults
COVID-19 infection associated with increased risk of new-onset vascular dementia in older adults
COVID-19 infection linked to a 41% higher risk of developing new-onset vascular dementia in older adults, with researchers warning that the virus may have lasting effects on brain and vascular health even after recovery.

New study reveals molecular basis of Long COVID brain fog
New study reveals molecular basis of Long COVID brain fog
“the researchers found a notable and widespread increase in the density of AMPARs across the brains of patients. This elevated receptor density was directly correlated with the severity of their cognitive impairment, suggesting a clear link between these molecular changes and the symptoms. Additionally, the concentrations of various inflammatory markers were also correlated with AMPAR levels, indicating a possible interaction between inflammation and receptor expression.”

“Covid damages the part of your brain (frontal lobe) which is responsible for empathy, emotional regulation & overcoming self-centeredness.

This will facilitate immorality.

Each & every infection you have causes damage.

Many are on infection 4 (or more).

Signed, a neurologist.”

“Let’s talk about COVID, brain damage & society.

Specifically, what happens when a neurotropic virus repeatedly infects the population, targeting the frontal lobe & almost nobody talks about the consequences?

This thread is for the skeptics.

Human challenge study reveals lasting cognitive decline after mild COVID-19

Mapping brain changes in post-COVID-19 cognitive decline via FDG PET hypometabolism and EEG slowing
Cognitive decline is a common symptom of post-COVID-19 syndrome. However, the mechanisms underlying this deficit remain poorly understood. This study aims to investigate the relationship between brain metabolic and neurophysiological alteration patterns in patients with persistent subjective cognitive decline after mild COVID-19 using joint FDG-PET and EEG analyses.

Lacking focus, tired always? Could be brain fog
Lacking focus, tired always? Could be brain fog

“Brain fog may gradually evolve into a slight memory problem, difficulty finding the right word for things, objects, situations and then registering new information.”

A widely held notion is that SARS2 activates our immune systems, causing an inflammatory response in the brain.

“A new study that is the first to compare inflammation and brain stress responses in long COVID-19 patients with individuals who have fully recovered shows that those with continued brain fog and other cognitive issues have a lower ability to adapt to stress and higher levels of inflammation in their brains.”

"Patients suffering from COVID-19 have been found to exhibit dementia-related biomarkers.. The findings of this study suggest a potential link between mild-to-moderate SARS-CoV-2 infection and the initiation or acceleration of brain β-amyloid pathology, and hint at the possibility of an increased future incidence of Alzheimer’s disease subsequent to the COVID-19 pandemic."
