Significantly increased risk of Alzheimer’s disease due to COVID-19
If elderly COVID-19 according to a recent study, the risk will increase over the next year Alzheimer’s disease fell ill, almost twice. The suspicion of a link between COVID-19 and dementia appears to be confirmed.
In a new study involving experts from Case Western Reserve University School of Medicine Anonymized electronic health data of millions of inpatients and outpatients has been evaluated to determine possible links between COVID-19 and subsequent Alzheimer’s disease. The results were published inJournal of Alzheimer’s Disease” came out.
The participants were at least 65 years of age.
In research work, medical records 6.2 million people take into account that already at least 65 years old were old. The participants were treated between February 2020 and May 2021 and had not previously been diagnosed with Alzheimer’s disease.
Then these participants became two groups educated. There was a group of people who in the indicated period COVID-19 were sick. The other group included people who had no documented cases of COVID-19, the team said.
More than 400,000 members assigned to the COVID group. On the other hand, there were about 5.8 million peoplewho did not have COVID-19 and who constituted the control group.
Increased risk of Alzheimer’s disease
Data analysis showed that participants who over 65 and previously ill with COVID-19 were at significantly higher risk of developing Alzheimer’s within a year of being diagnosed with COVID-19.
The greatest risk is associated Womendie 85 years and older were, the researchers report.
Double Risk of Alzheimer’s from COVID-19
According to experts, the results of the study show that older people Alzheimer’s Risk throughout the year COVID-19 almost doubled (from 0.35 percent to 0.68 percent).
However, it is unclear whether the disease caused by COVID-19 is a new development of Alzheimer’s disease. triggers or developing only Alzheimer’s disease accelerated.
The role of viral infections and inflammation
„The factors that play a role in the development of Alzheimer’s disease are poorly understood, but two factors are considered important: past infections, especially viral infections, and inflammation.explains the author of the study. Professor Pamela Davis in one Press release.
„Since SARS-CoV2 infection is associated with abnormalities of the central nervous system, including inflammation, we wanted to test whether COVID could also lead to an increase in diagnoses in the short term.the doctor adds. The result clearly confirms this.
A future massive rise in Alzheimer’s cases?
„Alzheimer’s is a serious and severe disease, and we thought we could control it by reducing common risk factors such as high blood pressure, heart disease, obesity, and a sedentary lifestyle.“, So Professor Davis.
But if research continues to increase the number of new Alzheimer’s diagnoses among people affected by COVID-19, the burden on the health care system and the need for resources for long-term care will increase significantly again.
Need to analyze possible complications of COVID-19
The expert adds that a large number of people in the United States have been ill or are suffering from COVID-19, although the long-term consequences can by no means be foreseen. Therefore, the impact of COVID-19 on other possible health problems and diseases should be closely monitored.
The team is already planning the impact Alzheimer’s disease and other neurodegenerative diseases for further investigation, the author of the study adds Professor Rong Xu added. The study will focus in particular on what Subpopulations may be especially vulnerable.
The goal is also to explore the potential of drugs that have already been approved when it comes to their use. change the original target and use them to treat COVID-19, so Xu. (as)
