Investigating the Neuroimmune, Cerebrovascular, and Cognitive Disturbances Associated with SARS‑CoV‑2 Infection: A Systematic Review of Post‑Acute Outcomes | Research Square
“A systematic review of 73,435 COVID-19 survivors found that 42% had persistent neuroinflammation, 22% had cerebrovascular injury, and 58% had cognitive impairment.”

Correct ✅ Covid 19 is causing widespread brain damage on a global scale. SARS-CoV-2 damages the brain. FACT. Brain fog, memory issues, more mistakes/crashes/accidents, less empathy, worsening mental health/emotional regulation. The signs are clear.

Cross-Section of Neurological Manifestations Among SARS-CoV-2 Omicron Subvariants—Single-Center Study
“The Omicron variant of SARS-CoV-2 presents a wide spectrum of neurological manifestations."
"Although there is an improvement in the survival rate of patients with COVID-19, the frequency of neurological manifestations increases."
"The occurrence of delirium, cerebrovascular diseases, and ischemic stroke results in higher mortality."
Brain-wide alterations revealed by spatial transcriptomics and proteomics in COVID-19 infection
“We identified dysregulation of mitochondrial and synaptic pathways in deep-layer excitatory neurons and upregulation of neuroinflammation in glia, consistent across both mRNA and protein. Remarkably, these alterations overlapped substantially with changes in age-related neurodegenerative diseases, including Parkinson’s disease and Alzheimer’s disease”

If you’re not noticing the (obvious) cognitive impairment in practically everyone around you, it may be due to your own cognitive decline.
“If you’re not noticing the (obvious) cognitive impairment in practically everyone around you, it may be due to your own cognitive decline.
Or denial is rearing its ugly head once again.
Perhaps it’s easier for me considering my background, but honestly, it’s so bloody palpable.”
Cognitive profile following COVID-19 infection: Clinical predictors leading to neuropsychological impairment
Covid itself causes cognitive impairment. From 2020, prior to Covid vaccination of any kind:
“In our cohort of COVID-19 patients neurologic manifestations were frequent, including cognitive impairment.”
Driving Under the Cognitive Influence of COVID-19: Exploring the Impact of Acute SARS-CoV-2 Infection on Road Safety | Neurology
"The study suggests that acute COVID-19, regardless of Long COVID status, is linked to an increased risk of car crashes presumably due to neurologic changes caused by SARS-CoV-2."
Neurological complications caused by SARS-CoV-2
Very comprehensive evaluation of known neurological damage from SarsCov2:
“The pathogenesis of neurological disorders caused by SARS-CoV-2 involves several mechanisms. First, SARS-CoV-2 could enter the brain through retrograde transmission & hematogenous routes & disrupt brain function & structure, thus causing or exacerbating neurological disorders…”
