Dementia risk for people 55 and older has doubled, new study finds
Dementia cases in the U.S. are expected to double by 2060, with an estimated one million people diagnosed per year, according to a new study led by Johns Hopkins University and other institutions.
Researchers found that Americans’ risk of developing dementia after age 55 is 42%, double the risk that has been identified in prior studies, a press release stated.
For those who reach 75 years of age, the lifetime risk exceeds 50%, the study found.

The study, which was published in the journal Nature Medicine on Jan. 13, analyzed data from the Atherosclerosis Risk in Communities Neurocognitive Study (ARIC-NCS), which has tracked the cognitive and vascular health of nearly 16,000 adults since 1987.

“Our study results forecast a dramatic rise in the burden from dementia in the United States over the coming decades, with one in two Americans expected to experience cognitive difficulties after age 55,” said study senior investigator and epidemiologist Josef Coresh, MD, PhD, who serves as the founding director of the Optimal Aging Institute at NYU Langone, in the release.
Understanding risk factors
“One of the main reasons for the increase is that great medicine and tecnological advances are keeping us alive longer and age is a risk factor for dementia,” Dr. Marc Siegel, clinical professor of medicine at NYU Langone Health and Fox News senior medical analyst, told Fox News Digital.
“Obesity is associated with inflammation, diabetes and high blood pressure, which are all independent risk factors for dementia.”
In addition to aging, other risk factors include genetics, obesity, hypertension, diabetes, unhealthy diets of ultraprocessed foods, sedentary lifestyles and mental health disorders, the release said.
“We have an obesity epidemic with over 45% adults obese in the U.S.,” Siegel noted. “Obesity is associated with inflammation, diabetes and high blood pressure, which are all independent risk factors for dementia.”
“And as an unhealthy population, we also have more heart disease, and atrial fibrillation is a risk factor for cognitive decline,” he added.
Dementia risk was found to be higher among people who have a variant of the APOE4 gene, which has been linked to late-onset Alzheimer’s disease. Black adults also have a higher risk.

Research has shown that the same interventions used to prevent heart disease risk could also prevent or slow down dementia, the study suggested.
“The pending population boom in dementia cases poses significant challenges for health policymakers in particular, who must refocus their efforts on strategies to minimize the severity of dementia cases, as well as plans to provide more health care services for those with dementia,” said Coresh.

What needs to change?
Professor Adrian Owen, PhD, neuroscientist and chief scientific officer at Creyos, a Canada-based company that specializes in cognitive assessment and brain health, referred to the increase in dementia cases as a “tidal wave.”
“This new study’s anticipated surge in dementia cases underscores the urgent need for early and accurate detection,” he told Fox News Digital.
“By catching issues early, we give people the power to make lifestyle adjustments, seek available treatments and plan their futures with clarity.”
“By identifying cognitive decline at its earliest stages, we have an opportunity to intervene before patients and families bear the full weight of the disease.”
Owen recommends conducting regular cognitive assessments as part of routine check-ups to proactively identify early signs of cognitive decline.

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.”
