People With Dementia Are Twice as Likely to Get Covid, Huge Study Finds

  People With Dementia Are Twice as Likely to Get Covid, Huge Study Finds People with dementia had significantly greater risk of contracting the coronavirus, and they were much more likely to be hospitalized and die from it, than people without dementia, a new study of millions of medical records in the United States has found. Their risk could not be entirely explained by characteristics common to people with dementia that are known risk factors for Covid-19: old age, living in a nursing home and having conditions like obesity, asthma, diabetes and cardiovascular disease. After researchers adjusted for those factors, Americans with dementia were still twice as likely to have gotten Covid-19 as of late last summer.

People living in poorer neighborhoods might be at risk of their brains aging faster, a new study has found. Researchers from the University of Wisconsin School of Medicine and Public Health analyzed health data from 601 people, average age 59, from another study. Sixty-nine percent had a family history of dementia. Participants had an MRI scan of their brains taken at the start of the study, then again every three to five years for a decade. They were also given memory and cognitive tests every two years.

When the study began, there was no difference in brain volume based on where the participants lived. By the end of the study, people who lived in poorer areas experienced more brain shrinkage and a faster decline in cognitive tests used to measure the risk of Alzheimer's disease.

If You Feel This, Your COVID Vaccine Is Working

  If You Feel This, Your COVID Vaccine Is Working These reactions mean the COVID-19 vaccine is working well: fever, chills, muscle pain, fatigue, headache and nausea.

What could cause this?

"Some possible causes of these brain changes may include air pollution, lack of access to healthy food and healthcare and stressful life events," said study author Amy J. H. Kind. "Further research into possible social and biological pathways may help physicians, researchers and policymakers identify effective avenues for prevention and intervention in Alzheimer's disease and related dementia."

"Our findings suggest that increased vigilance by healthcare providers for early signs of dementia may be particularly important in this vulnerable population," said Kind.

How common is dementia?

The genesis of dementia—an umbrella term for several conditions that involve a decline in memory, judgment and the ability to communicate—is unclear. But the risk increases with age. About 14 percent of Americans over age 71 have some form of dementia, about 3.4 million people overall.

This May Double Your Risk of Dementia, Study Shows

  This May Double Your Risk of Dementia, Study Shows Those who get 5 or less hours of sleep per night are twice as likely to develop dementia than those who slept seven to eight hours per night. Even more, they discovered a link between sleep disturbance and sleep deficiency with overall risk of death. "Our findings illuminate a connection between sleep deficiency and risk of dementia and confirm the importance of efforts to help older individuals obtain sufficient sleep each night," lead author, Rebecca Robbins of the Division of Sleep and Circadian Disorders, explained in a Harvard press release.

"Worldwide, dementia is a major cause of illness and a devastating diagnosis," said Kind. "There are currently no treatments to cure the disease, so identifying possible modifiable risk factors is important. Compelling evidence exists that the social, economic, cultural and physical conditions in which humans live may affect health. We wanted to determine if these neighborhood conditions increase the risk for the neurodegeneration and cognitive decline associated with the earliest stages of Alzheimer's disease and dementia."

This is a "Significant" Factor in Getting Dementia, New Study Shows .
According to a recent study sustaining a head injury may increase your chances of developing dementia later in life. Using data from over 14,000 people who participated in the Atherosclerosis Risk in Communities Study, they identified that a quarter (24%) had suffered a head injury. The participants were followed for a median of 25. Then, using cognitive assessments, interviews, medical codes and death certificate codes researchers were able to identify dementia cases. They determined that those who had suffered a head injury were 1.25 times more likely to develop dementia than those who hadn't.
