Older Adults Who Caught COVID-19 At Higher Risk Of Developing Alzheimer’s, Claims Study


Older adults with COVID-19 at higher risk of developing Alzheimer's, Study Claims

Researchers will do more research so that appropriate drugs can be developed.

Older adults infected with COVID-19 show a significantly higher risk of developing Alzheimer’s disease after one year, according to a new study. Research conducted on more than six million patients 65 years of age and older found an increased risk of the disease from 50% to 80% in these people. The highest risk was observed in women who were at least 85 years old. The study was published on Journal of Alzheimer’s Disease. However, scientists say it is not yet clear whether COVID-19 causes new development of Alzheimer’s disease or accelerates its emergence, according to the report. Science everyday.

“The factors that influence the development of Alzheimer’s disease are not well understood, but two are considered important: prior infection, especially viral infection, and inflammation,” said Pamela Davis, Professor. Distinguished College and Research Professors Arline H and Curtis F Garvin at the Case Western Reserve School of Medicine, and co-authors of the study are cited in this paper.

She added: “Since infection with SARS-CoV2 is associated with abnormalities of the central nervous system, including inflammation, we wanted to test whether COVID could lead to an increase in diagnoses. .

The team analyzed the eponymous health records of 6.2 million elderly people in the US who received medical treatment between February 2020 and May 2021. The researchers selected those who did not have a diagnosis. about Alzheimer’s disease, said Neuroscience News.

The members of the control group were divided into two groups – one group was those who had contracted COVID-19 during the study period and the other group had no recorded cases.

While 400,000 people belong to the first group, 5.8 million people belong to the second group.

Rong Xu, another co-author of the study, said they will continue to study the impact of COVID-19 on Alzheimer’s disease and other neurodegenerative disorders. They say these studies will help reposition drugs that have been approved to treat the long-term effects of COVID-19.
