Nasal injections comprising platelet-rich plasma derived from a patient's blood improve symptoms of smell loss associated with COVID-19 infection.
More severe COVID-19 outcomes associated with age-related macular degeneration likely arise from a genetic predisposition in addition to higher levels of Pdgf in blood serum.
Gene usage in the brains of those who suffered severe COVID-19 infections was similar to that observed in the aging brain. Researchers say COVID-19 is associated with molecular signatures of brain aging.
Patterns of cognitive impairments suffered by those infected with COVID-19 were similar to those of healthy people who are sleep deprived. Additionally, worse symptoms of cognitive impairment in coronavirus patients were directly correlated with more severe infection.
Brain cells exposed to blood taken from COVID-19 patients with delirium showed a decrease in neurogenesis and an increase in cell death. The findings also indicate a key role for cytokines produced in the immune system during infection and shed light on the molecular mechanisms of COVID-19 related delirium.
A new COVID-19 vaccine developed by researchers at the CNB-CSIC appears to protect against infection of the brain and neurological symptoms associated with coronavirus.
Autopsy tissue samples of 44 people who died of COVID-19 showed SAR-CoV-2, the virus responsible for coronavirus, spread throughout the body and to the brain, with traces of the virus lingering for 8 months.
People who contracted COVID-19 are significantly more likely to develop epilepsy or experience a seizure within 6 months of infection than those who contracted influenza.
COVID-19 infection causes microglia to excessively engulf synaptic structures and the upregulation of factors involved in phagocytosis.
Smaller life expectancy deficits associated with the COVID-19 pandemic were found in countries with more fully vaccinated people, researchers report.
SARS_CoV_2, the virus responsible for COVID-19 infects and replicates in astrocytes, reducing neural viability.
