Infection with the SARS-CoV-2 virus may significantly accelerate dementia in patients already suffering from the neurodegenerative condition, according to a study conducted in West Bengal. The research, published in the Journal of Alzheimer's Disease Reports, found that participants with all subtypes of dementia experienced rapidly progressive dementia following infection with SARS-CoV-2. Insights into the impact of COVID-19 on human cognition has so far remained unclear, with neurologists referring to it as "brain fog." The researchers investigated the effects of COVID-19 on cognitive impairment in 14 patients with preexisting dementia who had suffered further cognitive deterioration following the infection with SARS-CoV-2.
