“Other infections such as syphilis, cryptococcosis and Lyme disease have been associated with NPH. Possible mechanisms for NPH after COVID include disruption of choroid plexus cells by direct viral invasion or as a result of neuroinflammation and cytokine release and hypercoagulability leading to venous congestion and abnormalities of CSF flow.”

Cognitive Slowing, Dysfunction in Verbal Working Memory, Divided Attention and Response Inhibition in Post COVID-19 Condition in Young Adults
The present study revealed that in YOUNG adults, university students, without other comorbidities, there can be significant long-lasting cognitive impairments TWO YEARS after COVID-19 infection."
➡️"Specifically, verbal working memory was significantly impaired, and a lower performance was detected in divided attention and response inhibition.”

“Around 30% of those infected with COVID-19 experience lingering symptoms, with young adults showing cognitive impairments even two years after infection. Symptoms include persistent fatigue, trouble concentrating, and memory difficulties.”

Scientists find two brain biomarkers in long COVID sufferers that may be causing cognitive issues
“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.”

“That feeling when you know COVID can cause damage to the orbitofrontal cortex and you also know that this is almost certainly contributing to loss of empathy, increased impulsivity, and a prevalent inability to learn that changed circumstances warrant changed behaviour. 👇”
Expert warns common virus dramatically raises risk of early dementia

“We speculate that viral-triggered neuroinflammation and immune response contribute to neurotoxic damage in brain regions involved in cognitive processing, ultimately resulting in alterations in cortical morphology and glymphatic function.”

Brain 18F-FDG PET imaging in outpatients with post-COVID-19 conditions: findings and associations with clinical characteristics
“Outpatients with post-COVID-19 conditions exhibited extensive hypometabolic right fronto-temporal clusters. Patients with more numerous symptoms during the initial phase and with a longer duration of symptoms were at higher risk of persistent brain involvement.”

Brain damage to the frontal lobe (dorsal anterior cingulate cortex) causes apathy & reduces empathy.

More infections = more damage = more apathy.”

SARS-CoV-2 affects Alzheimer’s disease
"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."
