Dementia risk could be linked to walking speed, study suggests
A slower walking pace could be a sign of cognitive decline or dementia, a new study suggests.
Researchers assessed more than 16,800 healthy people over the age of 65 in the U.S. and Australia during a seven-year period (2010 to 2017), according to the published study in JAMA Network Open.
The investigators measured participants’ walking speed and performed cognitive tests every two years.

Those who demonstrated a decrease in walking speed by at least 2 inches per second a year — along with slower cognitive ability — had a higher risk of dementia, as compared to individuals considered to be “non-decliners, cognitive-only decliners or gait-only decliners,” according to the report.

“The combination of declining memory and slowing gait seems to be a stronger indicator of future dementia risk than decline in one of those things alone,” Dr. Taya A. Collyer, PhD, who led the study out of Monash University in Australia, told Fox News Digital.
Family members often comment that their loved one had changed prior to a dementia diagnosis, according to Dr. Amy Brodtmann, a neurologist and professor of the Cognitive Health Initiative at Monash University in Australia.

“There has long been an assumption that a slowdown – of walking, thinking and actions – is a sign not just of aging, but of developing cognitive impairment and dementia,” she told Fox News Digital.
‘Simple to measure’
The researchers suggested that measurement of walking speeds could be a useful tool – combined with other screening measures – to help identify individuals who are at risk of developing dementia and ensure that they receive early testing and preventive interventions.
“We don’t yet have a definitive test for dementia that family doctors can do in their own clinics,” noted Brodtmann, one of the co-authors of the study.

Walking speed is very “simple to measure,” Collyer added.
“Our study also suggests that family doctors might keep an eye on walking speed when they (or their patients) have concerns about dementia,” she said.
DEMENTIA RISK COULD BE HIGHER FOR OLDER ADULTS WHO EXPERIENCE THIS TYPE OF INJURY, STUDY FINDS
The manner in which a person walks, also known as the gait pattern, could help signal a potential issue, according to Edward Farrell, a physical therapist and certified strength specialist at Physical Solutions Physical Therapy and Fitness on Long Island, New York.
“Our gait pattern and speed requires reflexive planning, adjustments to surfaces, and focus and attention, which are often impaired with cognitive diseases,” Farrell, who was not involved with the study, told Fox News Digital.
Other risk factors
Courtney Kloske, PhD, director of scientific engagement for the Alzheimer’s Association in Chicago, Illinois, noted the importance of exploring other factors that may impact risk in diverse populations.
These risk factors include genetics, health conditions such as hypertension, health-related behaviors like physical activity and diet, and environmental elements, such as air pollution.
“Up to 45% of dementia cases could be delayed or prevented by adopting healthy lifestyle factors.”
“While not all factors are modifiable, research shows that up to 45% of dementia cases could be delayed or prevented by adopting healthy lifestyle factors,” Kloske, who was not involved in the study, told Fox News Digital, citing the 2024 Lancet Commission, a collaborative report from leading dementia experts.

The study highlights the benefits of adopting healthy lifestyle behaviors early and consistently, including helping to prevent or postpone the onset of cognitive decline, according to Kloske.
She recommends adhering to a healthy diet, maintaining a regular exercise routine, controlling diabetes and blood pressure, and staying socially engaged.
Step into health
Working to improve one’s walking stride is also important for overall health, according to Farrell.
“The ability to maintain a more normal gait stimulates our systems, allowing greater mobility, more independence and reduced fall risk,” he told Fox News Digital.
Farrell recommends taking frequent walks at various paces, with intervals of moderate to faster speeds, to improve reflexes. Certain exercises also support walking speed and pattern, he noted.

“Regular strength training like squats, step-ups, bridges and leg lifts can keep our foundational muscles strong as we age,” he advised.
“Stretching to keep hamstrings, hip flexors and calf muscles limber allows for more free mobility to walk.”

Performing balance exercises like heel-toe walking, single leg stance drills and Tai chi can also improve stability and confidence with walking, Farrell noted.
For those who plan to start a walking program, it’s best to wear supportive sneakers that provide a stable base and cushioned comfort, the expert added.

Parasitic infection causing ‘explosive’ stomach illness exceeds 1,000 cases in northern state
NEWYou can now listen to Fox News articles!
Cases of cyclosporiasis infections are rising across America, with more than 1,000 people diagnosed in Michigan and more than 500 in Ohio.
This is the largest outbreak of its kind in Michigan’s history and one of the country’s largest in years, according to the Associated Press.
The parasitic infection can cause weeks of watery diarrhea. The source of the infections has not been identified and no deaths have been reported.
MYSTERY PARASITE LEAVES AMERICANS BATTLING ‘EXPLOSIVE’ ILLNESS AS CDC INVESTIGATES
Michigan officials announced the outbreak last week following the identification of more than 170 cases since June 22 in the southeastern part of the state. Typically, only about 50 cases are identified in Michigan each year, according to AP.

Similar illnesses have been reported in 28 other states, including neighboring Ohio, where diagnoses have popped up across the Michigan border.
Cases have been climbing since the CDC identified an uptick in infections in mid-June, with illnesses now reported in dozens of states.

Texas has reported at least 48 cases, and illnesses have been identified in numerous other states as health officials investigate the source.
The hallmark symptom of a cyclospora infection is watery, often “explosive” diarrhea that can last for weeks or even months if left untreated, the CDC says.
Other symptoms of cyclosporiasis include severe abdominal cramping, bloating, nausea, fatigue and significant weight loss. (iStock)

While the infection can sometimes clear up on its own, it frequently requires antibiotics. The CDC advises anyone experiencing symptoms of cyclosporiasis to contact a healthcare provider for testing and treatment.
The CDC, alongside the Food and Drug Administration and state health officials, is actively investigating several multistate clusters, but they have yet to find a cause behind the spread.
Fresh produce should be washed thoroughly before eating, although this may not eliminate the risk of infection, the AP noted. (iStock)
Past infections have reportedly been linked to consuming contamined fruits or vegetables, or being exposed to contaminated irrigation water.

Washington, DC – GLP-1 weight-loss drugs have become a prevalent part of American healthcare, and the current administration is getting behind the movement.
In an exclusive interview with Fox News Digital at the Great American State Fair in the nation’s capital on July 6, CMS Administrator Dr. Mehmet Oz voiced his support for the use of GLP-1 (glucagon-like peptide-1) medications, such as Ozempic, for appropriate uses.
“I’m a fan of GLP-1 drugs when used correctly,” he said. “They do help people who are overweight lose weight quite effectively. They’re not a replacement for diet and exercise, but they might jumpstart the system so it’s easier for you to use healthier tactics.”
DR OZ WARNS MEDICARE SCAMMERS ARE STEALING BILLIONS — AND YOUR PERSONAL INFORMATION COULD BE NEXT
This is especially helpful for those who may have trouble moving due to joint pain or are experiencing internal dysfunction, Oz said.
Certain GLP-1 drugs are covered by Medicare for overweight candidates with certain conditions, such as high blood pressure and diabetes, and Oz projected the benefits will continue to benefit taxpayers.

“We believe these are so effective in reducing conditions like high blood pressure and diabetes that they’ll actually save money for the federal taxpayer, because [they’re] going to make you healthy enough that you don’t have to consume health services,” Oz said.

“We think about 70% of all the money we spend on healthcare is caused by chronic conditions, and obesity is the No. 1 driver of all that, so it’s a smart decision.”
Oz recently announced the launch of the Medicare GLP-1 Bridge program, which will allow more seniors to access GLP-1 drugs for only $50 a month if they meet qualifying health criteria and receive prior authorization from a doctor.
The doctor expressed support for broadening affordable access to GLP-1 medications for Americans. (iStock)
“There are a lot of overweight people who don’t have high blood pressure, diabetes or other conditions, so they don’t get access to the drug normally,” he said. “We want them to have the ability to use it as well.”
Although these access shifts could boost Americans’ overall health — and in some cases could be lifesaving — Oz noted that there is “no silver bullet” when it comes to these medications.

“I love the fact that the innovation that’s coming out of pharmaceutical companies is allowing us to save lives and make lives better,” he said. “But the real secret to longevity is eating right, exercising, sleeping, dealing with the stress of your life, finding some purpose in your existence [and] realizing you have agency over the future.”
“These are things that your mom would have told you [and that] you don’t need a doctor to be emphasizing.”
Medicating appropriately, combined with eating right, exercising and staying connected with others, can help make health goals attainable, the doctor said. (iStock)
While GLP-1s may not be a fix-all, combining these medications with foundational health practices “makes a lot of sense,” Oz said.

“I don’t want people being fat-shamed … I don’t want you feeling guilty that you’re gaining weight even though everyone else around you seems to have figured it out,” he said. “It’s not that simple — our set points for hunger are different. We have different things going on in our lives.”

“But if you realize how precious you are — the temple of the soul is so valuable. It’s the greatest gift your parents ever gave you, and you take advantage of every tool out there to make it work … which includes using medications when appropriate. That, to me, is MAHA.”
