New research published today in the Journal of Alzheimers Disease shows elderly Covid patients have a dramatically increased risk of developing Alzheimers.

In this retrospective cohort study of 6,245,282 older adults (age ≥65 years) who had medical encounters between 2/2020–5/2021, we show that people with COVID-19 were at significantly increased risk for new diagnosis of Alzheimer’s disease within 360 days after the initial COVID-19 diagnosis (hazard ratio or HR:1.69, 95% CI: 1.53–1.72), especially in people age ≥85 years and in women.

Older people who were infected with COVID-19 show a substantially higher risk — as much as 50% to 80% higher than a control group — of developing Alzheimer’s disease within a year, according to a study of more than 6 million patients 65 and older.
