Mini-strokes may cause surprising long-term health issue, experts warn
Prolonged fatigue could indicate poor sleep habits — but it could also be a lingering effect of mini-strokes.
That’s according to a new study from Aalborg University Hospital in Denmark, which was published this week in Neurology, the medical journal of the American Academy of Neurology (AAN).
A mini-stroke — medically known as a transient ischemic attack (TIA) — is a temporary blockage of blood flow to the brain that causes a “short period of symptoms,” according to Mayo Clinic.
STROKE, DEMENTIA AND DEPRESSION SHARE THESE 17 PREVENTABLE RISK FACTORS
The study found that people who experience a TIA are more likely to report prolonged fatigue lasting up to one year.
“Patients with a presumed transient event reported fatigue at levels comparable to a stroke,” lead study author Birgitte Hede Ebbesen, PT, PhD, a physiotherapist at Aalborg University Hospital, told Fox News Digital.

The researchers followed 354 people averaging 70 years of age who had experienced a mini-stroke.
Over a 12-month period, the participants reported their level of fatigue in five areas: overall tiredness, physical tiredness, reduced activity, reduced motivation and mental fatigue, according to a university press release.

On a scale ranging from 4 to 20 — with 20 being the most fatigued — the participants reported an average score of 12.3 in the two weeks after the mini-stroke, 11.9 at three months, 11.4 at six months and 11.1 at the one-year mark.
Two weeks after the mini-stroke, 61% reported high levels of fatigue. At three, six and 12 months, 54% said they experienced fatigue.

Those who reported prolonged fatigue were twice as likely to have experienced anxiety and/or depression, the study found. Some also reported
“We had encountered fatigue among patients with TIA in clinical settings, so we knew it was there — but the frequency still surprised us,” Modrau told Fox News Digital.
FEELING EXTRA TIRED? THIS VIRUS COULD BE THE CULPRIT, STUDY SUGGESTS
“Long-term fatigue was common in our group of study participants, and we found that if people experience fatigue within two weeks of leaving the hospital, it is likely they will continue to have fatigue for up to a year.”
Based on these findings, Modrau suggests that people diagnosed with a transient ischemic attack should be monitored for lingering fatigue in the ensuing weeks and months.

“This could help us better understand who might struggle with fatigue long-term and require further care.”
The more commonly known symptoms of stroke include face drooping, arm weakness or slurred speech, which usually resolve within a day, according to Modrau. Some patients also reported long-term cognitive issues.
Causes of post-stroke fatigue
Bradley Serwer, an interventional cardiologist and chief medical officer at VitalSolution, an Ingenovis Health company that offers cardiovascular and anesthesiology services to hospitals nationwide, confirmed that fatigue is very common — and sometimes “debilitating” — following a stroke.
“Fatigue is multifactorial and can rarely be attributed to a single cause,” Serwer, who was not involved in the study, told Fox News Digital.
“Fatigue is multifactorial and can rarely be attributed to a single cause.”
The Maryland-based cardiologist shared the following potential reasons for fatigue following a mini-stroke.
Brain healing: “After a stroke, the brain tries to heal itself,” Serwer said. “This process causes the brain to work harder to ‘rewire’ itself, which results in a higher demand for energy. This often leaves patients feeling drained or fatigued.”
Increased inflammation: This can occur due to the immune response following a TIA.

Lower levels of neurotransmitters in the brain: Reduced levels of chemicals like serotonin, dopamine and norepinephrine can result in depression, fatigue or lack of motivation, according to Serwer.
Sleep disturbances: “These are very common after a stroke and can lead to significant sleep deprivation,” the cardiologist said.
Medications: Drugs used to treat strokes may have adverse side effects, including fatigue. “Betablockers are excellent blood pressure medications and are often prescribed after a stroke or heart attack, but they may cause notable fatigue,” Serwer noted.
Other factors: “Simple tasks may require more mental effort than before the injury,” the cardiologist said. “Depression or anxiety after a stroke can also be a confounding predictor of fatigue.”

Potential limitations
The study did have some limitations, the researchers noted.
“It is an observational study and therefore we cannot determine causality,” Modrau said.
“Results are based on self-reported questionnaires, and we cannot be certain that relatives didn’t help fill them out or influence results.”

The researchers also did not have information on pre-TIA fatigue levels, although previous studies suggested that it was “much more frequent” after mini-strokes.
Looking ahead, Modrau said she hopes healthcare providers begin to acknowledge lasting fatigue after TIA and provide care pathways for these patients.

“Up until now, patients with lasting challenges after TIA have been left alone in many cases,” she told Fox News Digital.
“We as a society should start to acknowledge their difficulties instead of viewing them as ‘the lucky ones,’” she continued. “My aim with this study has been to give these patients a voice – and to start to listen to their struggles.”

One walking habit could signal a healthier brain after 80, scientists say
NEWYou can now listen to Fox News articles!
Older adults identified as “super movers” are about half as likely to develop cognitive impairment than their peers.
That’s according to a recent study led by Stony Brook Medicine in New York, which evaluated the cognitive function of 4,000 adults 80 and over who participated in multiple aging and longevity studies over several years.
Among this group, 6% to 10% were classified as super movers, which means they walk at a much faster pace than others of the same age and gender — at speeds comparable to people three decades younger.
COMMON VITAMIN MAY INFLUENCE BRAIN AGING IN WAYS SCIENTISTS DIDN’T EXPECT
The super movers were found to have about half the risk of cognitive decline compared to seniors with typical gait speed.
The findings were published in the journal Neurology on June 16.

“The study reinforces that mobility and brain health are closely connected,” lead study author Dr. Joe Verghese, MD, neurologist at Stony Brook Medicine, told Fox News Digital. “This suggests that preserving mobility may be an important marker of healthy brain aging and resilience.”
‘LONGEVITY GENE’ MAY PROTECT THE BRAIN FROM ALZHEIMER’S BY BOOSTING DNA REPAIR, STUDY FINDS
The most intriguing finding, according to Verghese, was that super movers maintained cognitive function despite having similar dementia-related brain changes as their peers.
In postmortem brain analysis, there was no difference in dementia-related pathologies between the super movers and the slower walkers, the study stated.

“This suggests they may possess resilience mechanisms that help preserve brain function even in the presence of age-related changes,” he said. “Understanding these resilience factors could lead to new strategies for promoting healthy brain aging.”
As the study was observational, there were some limitations, and it does not prove that walking faster prevents dementia, the researchers noted.

“Other factors, such as cardiovascular health, physical fitness or genetics, may also contribute to both faster walking and better cognitive outcomes,” Verghese said.

This study adds to growing evidence that what’s good for the heart and muscles also benefits the brain, he noted, adding that “staying physically active remains one of the most effective, evidence-based ways to support healthy aging.”
“Walking speed is best viewed as a marker of overall health, not a treatment.”
“The broader message is that physical activity is important at any age,” Verghese said. “Walking is an easy step-up point because you don’t need any special equipment. You can do it inside or outdoors, and you can do it on a regular basis. You can walk with a dog, you can walk with a friend.”
Any activity is beneficial if it’s done regularly and with the right intensity, he added.

Rather than just trying to walk faster, the neurologist recommends that seniors focus on maintaining mobility through regular physical activity, strength training, balance exercises and good cardiovascular health.
“Walking speed is best viewed as a marker of overall health, not a treatment,” Verghese noted.
Major public health guidelines from the CDC and U.S. Physical Activity Guidelines recommend at least 150 minutes of moderate-intensity aerobic activity each week, such as brisk walking.

This can be achieved by walking 30 minutes a day, five days a week, or about 20 to 25 minutes most days. Another option is to engage in shorter sessions that add up over the day.

“You have to do it within your health limitations and medical conditions,” Verghese advised. “So if there are any medical concerns, I would get your physician to clear you before starting exercise.” The good thing about walking, he added, is that you can start at a slow pace and then gradually build up to a brisker pace.
“And then adding on strength and balance training, whatever age you are, I think is also important.”

Dr Oz warns Medicare scammers are stealing billions — and your personal information could be next
NEWYou can now listen to Fox News articles!
Washington, D.C. – Medicare fraud is a multibillion-dollar problem that government officials say threatens both taxpayer dollars and Americans’ personal identities.
In a July 6 interview with Fox News Digital at the Great American State Fair in Washington, D.C., Dr. Mehmet Oz warned that every dollar stolen through Medicare fraud is a dollar taxpayers lose – a problem that has worsened since the COVID pandemic.
“If I had to just pick one thing to focus on to make healthcare more affordable in America, I’d go to health fraud and all the waste and abuse that accompanies it,” said Oz, who is the administrator of the Centers for Medicare & Medicaid Services. “And just to put this in perspective, we think it’s about $100 billion a year.”

Medicare fraud can include billing for services that were never provided, overcharging for medical equipment, using stolen patient or doctor information, or performing unnecessary procedures, according to the U.S. Government Accountability Office.

As the Trump administration ramped up efforts to combat fraud, CMS reported $41.9 billion in Medicare program integrity savings in 2025, up 59% from $26.3 billion in 2024.

Medicare fraud not only harms the federal budget and steals from taxpayers, but exposes seniors to identity theft, unnecessary care, higher premiums and reduced access, Oz cautioned.

Removing corruption from the healthcare system will have the greatest impact among seniors, since “so much of the fraud is perpetrated against them,” the administrator said.
“I’m talking about people tricking seniors to give up their Medicare beneficiary numbers, which is like a credit card basically,” he said. “These scammers can take those numbers and use them for all kinds of illegitimate purposes.”

“People are stealing from you by pretending to send you drugs you don’t want, wheelchairs you don’t need, [and] services you never asked for or don’t benefit from,” Oz added.
To prevent this, he shared his top advice for seniors: Do not give your Medicare beneficiary number to anybody, do not answer questions on a phone call from an unknown person and do not give away personal information.

“These scammers are calling seniors, tricking them, and once they have key information, they can steal it,” he said. “And I won’t know it and you won’t know it.”
“We want to protect people who need these programs the most,” Oz went on. “You do that by making sure scoundrels don’t corrupt the systems and steal money out of the till that is designed to help folks in dire straits when they’re vulnerable and in need of services.”
Seniors should never share their Medicare information with unknown people, the administrator advised. (iStock)
Removing fraud could “double the life expectancy of the trust fund that makes all this possible,” Oz predicted.
“If you’re worried about Medicare being there when you’re ready to retire in a couple decades, depending on how old you are, and you’re concerned that it might not last because of all the fraud that’s hitting it … you’ve got a good [reason to] worry,” he said.
