What do we know about covid-19’s effects on the brain?

Freelance journalist Katharine Lang investigates the neurological impact of SARS-CoV-2 infection, highlighting symptoms such as brain fog, loss of smell, and cognitive dysfunction. Studies show that these effects can persist in both severe and mild cases of Covid-19, with older individuals and those with pre-existing neurological disorders at higher risk. The exact mechanism behind these symptoms is still debated, with inflammation playing a significant role. Neurological symptoms like microbleeds and strokes have also been reported post-infection. Vaccination may help reduce the risk of neurological effects, emphasizing the importance of prevention strategies in managing long-term consequences of Covid-19 on the brain.
