A american studypublished Tuesday, September 13, in the Journal of Alzheimer’s Disease revealed that people over the age of 65 who contracted the Covid-19 were more likely to contract the disease than Alzheimer in the year following their contamination, spotted TF1.
Co-author of the study, Professor Pamela Davis explains that previous infections, especially viral ones, as well as inflammations increase the risk of developing this neurodegenerative pathology. “Covid has been associated with abnormalities of the central nervous system”, develops the researcher.
Double the risk
This discovery is significant since it means that, in the years to come, many diagnoses of Alzheimer’s disease could be established given the scale of the Covid-19 pandemic. To reach this conclusion, the scientists compared the medical data of 400,000 patients diagnosed positive for Covid-19 with those of 5.8 million uninfected patients.
According to this study, the risk of developing Alzheimer’s disease in the year following their infection with Covid-19 would thus be doubled. It would indeed go from 0.35% for the control group to 0.68% for the sample of contaminated patients. However, this study does not specify whether the coronavirus causes new cases of Alzheimer’s or whether it reveals the symptoms in people who did not know they were affected by this disease.
