Unraveling the enigma of long COVID: novel aspects in pathogenesis, diagnosis, and treatment protocols
“The nervous system, particularly the brain, can become infected by SARS-CoV-2 early in the course of COVID-19 via viral access through the cribriform plate located at the upper part of the nose.. this route is more ominous than previously thought. The pits of the cribriform plate and areas beneath the olfactory bulb including potential spaces such as the air sinuses can be a reservoir for not only viral persistence, but also its replication.. the upper part of the nose and the structures surrounding it appear to be ideal sites for access to the CNS (central nervous system).. This can cause a low-grade inflammation in the meninges and deeper tissues in the neuronal environment triggering neuroinflammation.. [This can cause] Symptoms such as brain fog, cognitive deficits, prolonged anosmia, memory deficits, and deposition of amyloid-like fibrils that cause premature aging in patients with long COVID.."
It's certainly ominous that SARS-CoV-2 can infect my brain instantly and silently.”

Brain abnormalities in survivors of COVID-19 after 2-year recovery: a functional MRI study
Even 27 months after recovering from COVID-19, many people still suffer from brain-related issues like cognitive failures and mental fatigue. A recent study used brain scans (fMRI) to investigate why.

Severe acute respiratory syndrome coronavirus 2 infection leads to Tau pathological signature in neurons
“It is now evident that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection results in a wide range of long-term neurological symptoms and is worryingly associated with the aggravation of Alzheimer’s disease. Little is known about the molecular basis of these manifestations.”

Neurological damages in COVID‐19 patients: Mechanisms and preventive interventions
Brain Pathology in COVID-19: Clinical Manifestations and Potential Mechanisms
Even though Omicron caused less severe disease than Delta, the incidence of neurological manifestations is similar. More than 30% of patients experienced 'brain fog', delirium, stroke, and cognitive impairment, and over half of these patients presented abnormal neuroimaging outcomes.. The most frequent imaging features (affecting >60% of patients) include ischemic infarcts, intracerebral hemorrhages, perfusion abnormalities, and leptomeningeal enhancement. Hypometabolism in the pons, cerebellum, bilateral insula, bilateral medial lobes, and prefrontal cortex indicates brain function dysregulation in COVID patients. The high incidence of cerebrovascular events such as ischemic stroke and intracerebral hemorrhage, indicates potential endothelial injury and coagulation dysfunction. Other investigations have also reported hypoxic alterations in the cerebellum and cerebrum, metabolic alterations of astrocytes, microglial activation, neuro-axonal damage, and neuronal loss.."
