Long COVID patients are up to 5 times more likely to have dementia after COVID-19

Publication date: Apr 16, 2025

Although mild cognitive impairment is not always a sign of dementia, one in six people with these symptoms is diagnosed with dementia within a year. Early research showed that up to a third of people 65 and older suffering from long-covid met the criteria for mild cognitive impairment, a precursor to dementia. This is four to five times higher in prevalence compared to the same age group without long-COVID symptoms. Depending on individual circumstances, it is known to be as short as 4 weeks or more after infection and as long as 12 weeks or more. The research team conducted a study on 4,000 patients with COVID-19 when they were over the age of 60.
