Dementia has 2 shocking new risk factors, study finds, with total of 14 now on list
![Dementia has 2 shocking new risk factors, study finds, with total of 14 now on list Dementia has 2 shocking new risk factors, study finds, with total of 14 now on list](https://static.foxnews.com/foxnews.com/content/uploads/2024/08/vision-cholesterol-split.jpg)
Two surprising new risk factors for Alzheimer’s disease are noted in a new study.
Untreated vision loss and high levels of LDL cholesterol have been linked to a greater chance of developing the common dementia type.
Low-density lipoprotein (LDL), which is sometimes called “bad cholesterol,” is associated with negative health effects when present in high amounts.
HIGH BLOOD PRESSURE AND ALZHEIMER’S DISEASE COULD GO HAND IN HAND, STUDY FINDS
Researchers from University College London led the study, published in The Lancet on Aug. 10.
The findings were also presented at the Alzheimer’s Association International Conference (AAIC) in Philadelphia on July 31.

Vision loss and high LDL cholesterol join a list of 12 other risk factors the researchers previously identified in 2020.
Those 12 are hearing loss, lower education, smoking, hypertension, obesity, physical inactivity, depression, diabetes, excessive alcohol consumption, air pollution, traumatic brain injury and social isolation.
AI FAST-TRACKS DEMENTIA DIAGNOSES BY TAPPING INTO ‘HIDDEN INFORMATION’ IN BRAIN WAVES
To identify the two new risk factors, the researchers analyzed dozens of recent studies on vision loss and high cholesterol.
The 14 total factors are responsible for roughly half of dementia cases globally, the researchers stated, which means eliminating them could potentially prevent many cases.

About half of all Alzheimer’s cases can be attributed to 14 total factors, the researchers stated. (iStock)
“Some dementia risk factors, such as alcohol consumption and physical exercise, can be managed by changing your lifestyle, but many must be addressed on a societal level,” Fiona Carragher, chief policy and research officer at the Alzheimer’s Society in the U.K., said in a press release.
(The study was partly funded by the Alzheimer’s Society.)
“Social isolation, education inequalities and air pollution are beyond individuals’ control and require public health interventions and joint action between government and industry.”
“I tell patients all the time, ‘if it’s healthy for the heart, it’s healthy for the brain.’”
Dr. Earnest Lee Murray, a board-certified neurologist at Jackson-Madison County General Hospital in Jackson, Tennessee, was not involved in the study but said it “substantiates a lot of things we have known about dementia for several years.”
He told Fox News Digital, “The study in Lancet shows higher levels of LDL (the bad cholesterol) — which is often related to diet and lifestyle choices — is related to a greater chance of developing a dementia process.”

“Genetic factors can play a role in elevated levels of LDL — however, even in these patients, diet modifications can be beneficial as well.”
The neurologist was also not surprised by the link between vision loss and development of dementia.
ALZHEIMER’S AND PARKINSON’S RISK IS HIGHER FOR PEOPLE WITH BODY FAT IN TWO SPECIFIC AREAS
“We have known for years that patients who have higher levels of education and are ‘well-read’ often develop dementia at a much later age,” Murray said.
“We rely heavily upon eyesight to be able to engage in our surroundings as well as stimulate cognitive thought.”
Reducing the risk
In his practice, Murray said, he is often asked about ways to prevent or reduce the risk of developing dementia at a later age.
“Patients have a good understanding of what a heart-healthy diet and lifestyle look like,” he told Fox News Digital.

The brain is a “very vascular organ,” the doctor pointed out — which means it is closely linked to the heart.
“I tell patients all the time, ‘If it’s healthy for the heart, it’s healthy for the brain,’” Murray said.

“This not only includes dietary changes, such as lower fat/lower cholesterol diets, but also lifestyle modifications, such as smoking and alcohol cessation.”
There is also evidence that the Mediterranean diet can be beneficial in delaying the onset of dementia, Murray noted.

“Regular exercise is beneficial from a vascular standpoint, and can also help from a mental standpoint,” a neurologist said. (iStock)
“Regular exercise is beneficial from a vascular standpoint, and can also help from a mental standpoint,” he added.
Participating in cognitively stimulating activities is also known to delay the potential onset of dementia, according to Murray.

“I tell my patients to find some cognitively challenging activity they enjoy, whether that’s working puzzles or reading challenging books,” he said.
“These activities can maintain a higher level of cognitive abilities and retard the onset of dementia.”

To prevent vision loss, the U.S. Centers for Disease Control and Prevention (CDC) recommends getting regular eye exams, wearing protective eye wear in high-risk environments and wearing sunglasses to prevent exposure to UV rays.
Knowing your family’s eye health history, eating a diet rich in fruits and vegetables, maintaining healthy blood sugar levels and avoiding smoking can also prevent vision loss, the agency added.

Blood banks searching for Type O blood amid emergency shortage: 'We always have a need'
![Blood banks searching for Type O blood amid emergency shortage: 'We always have a need' Blood banks searching for Type O blood amid emergency shortage: 'We always have a need'](https://static.foxnews.com/foxnews.com/content/uploads/2024/08/woman-donating-blood.jpg)
Las Vegas, Nevada – The nation is facing an emergency blood shortage, according to the American Red Cross.
Extreme heat and recent natural disasters are affecting the blood supply, the nonprofit says.
Not only is there a shortage of donations across the country, but there is also a specific need for Type O blood, according to Vitalant, an Arizona-based nonprofit that operates blood banks nationwide.
YOUNG GIRL SURVIVES CANCER THANKS TO LITTLE SISTER’S LIFESAVING DONATION: ‘A PERFECT MATCH’
To help meet the need, Vitalant is holding more than 50 blood drives this month in parts of Nevada.
“My best friend almost died in a car accident when I was, like, 19 or 20 — so I’ve seen the power of blood donations,” blood donor Nina Duren told Fox News.

Duren has been donating blood a couple of times a year for the last 15 years.
“It’s a life-saving thing I can do that costs me nothing but an hour of my time,” she said.

Another donor, Sheila Macdonell Spiess, is a retired trauma nurse. In the 47 years of her nursing career, she said there has always been a need for blood.
“People are always in car accidents, stabbings, unfortunately, or gunshot wounds, or [there are] people with leukemia,” she told Fox News.
“We always have a need. It doesn’t matter what time of year.”

There is a specific need for Type O blood, according to Vitalant, an Arizona-based nonprofit that operates blood banks nationwide. (iStock)
As blood banks across the nation are running low on blood, some are placing an emphasis on one blood type over others.
“Type O is known as a universal donor,” said MacDonell Spiess. “So, if you came in, and we needed to give you blood right away … it would be O, because we don’t know if you’re A or B or AB. So we would give you O, because that’s called the universal type.”
Vitalant’s Type O supply hit an 18-month low in July.
Without Type O blood readily available, people in need may be turned away.
The organization is now working to build up a constant four-day supply.

“If you just keep lowering the number and lowering the number … that just impacts how many people you can help, and honestly, no doctor wants to have to make that choice of saying you can’t be helped today,” Mike Doria, communication manager of Vitalant’s Southwest division, told Fox News.

The American Red Cross’ entire inventory has shrunk by 25%, and the supply of donors has not kept up with the need.
“As an example, a trauma victim may require dozens of blood products,” Dr. Baia Lasky, American Red Cross’ divisional chief medical officer, told Fox News.

“And studies have demonstrated that every minute of delay in blood products in these situations will increase the risk of death by 5%.”
That means having blood available for donation at hospitals is “absolutely critical” to give people a chance of survival after emergencies, she added.

Blood cannot be stored long-term, which means nonprofits like American Red Cross and Vitalant consistently need donors.
