Long COVID’s Lingering Impact: Brain Function Changes Can Persist for Months

People with long COVID have abnormal brain activity during memory tests, months after their initial COVID-19 infection, with less activity in the regions normally used for memory tasks, but more activity in other areas of the brain.

Could a Viral Illness Increase Chances of Developing Alzheimer’s or Other Neurodegenerative Disease?

Study reveals a significant association between certain viral illnesses, including viral encephalitis and pneumonia-causing flu with an increased risk of developing a neurodegenerative disorder later in life. Researchers say existing vaccines against the viruses may reduce the chances of developing neurodegeneration.
