Everyone knows cleaner air means healthier bodies, but new research suggests it might also help aging minds.
"Our study is important because it is one of the first to show that reducing air pollution over time may benefit the brain health of older women by decreasing their likelihood of developing dementia," said...
It's a move that could severely limit the number of people taking the controversial new Alzheimer's drug Aduhelm: Medicare on Tuesday proposed to only cover the cost of the pricey medication for people enrolled in approved clinical trials.
A final decision on coverage is expected later this year.
The drug costs $28,200 per year, but that cost will only be covered for participan...

Exercise helps you stay fit, hale and hearty, and researchers say it may also help you stave off dementia and Alzheimer's disease. Now they have a better understanding of the hidden benefits that aid the brain.
Older folks who are more physically active have higher levels of a protein that promotes better communication between the brain's synapses, a new study reports.
Following a months-long and unprecedented review, Medicare officials expect to announce within the next couple of weeks whether the program will cover the controversial Alzheimer's drug Aduhelm. The drug's benefits are in question and its annual price tag tops $28,000.
The U.S. Centers for Medicare and Medicaid Services (CMS) tend to cover with little fanfare most drugs approved by its s...
Many parents struggle with the decision to let their kids play tackle football or other contact sports due to the risk of concussions and long-term brain diseases that may occur with repeated head blows.
NFL players are four times more likely to die of Lou Gehrig's disease (ALS) than other people, new research finds, adding to known links between football-related head injuries and brain diseases, including Alzheimer's, Parkinson's and chronic traumatic encephalopathy (CTE).
And the longer they played football, the greater their risk, the new study found.
The sound of mom's voice can soothe a fussy baby like nothing else, but now new research suggests that an infant is also calmed by the scent of its mother.
Prior animal studies had already shown that olfaction -- smell -- "is very important, that mother's smell is very critical for attachment," noted study author Ruth Feldman. "Young recognize mother by her smell, and mother and habitat a...
Dirty air could cancel out some of the brain benefits of exercise, a new study suggests.
"Physical activity is associated with improved markers of brain health in areas with lower air pollution," said study author Melissa Furlong. "However, some beneficial effects essentially disappeared for vigorous physical activity in areas with the highest levels of air pollution." Furlong is an envi...
Right now, the devastating concussion-linked brain condition known as chronic traumatic encephalopathy (CTE) can only be diagnosed after death via autopsy. But new research could help change that, allowing doctors to someday spot the illness earlier.
According to the new study, MRI may be able to detect CTE while people are still alive.
"While this finding is not yet ready for the ...

People with a longtime history of epilepsy show signs of rapid brain aging that may raise their odds for developing dementia down the road.
This is the key finding of new research reporting that the brains of people with epilepsy that began in childhood appear to be about 10 years older than the brains of people without a history of this seizure disorder.
Coffee lovers know a steaming cup of java can quickly deliver energy and mental clarity every morning, but new research suggests it may also guard against Alzheimer's disease in the long run.
"Worldwide, a high proportion of adults drink coffee every day, making it one of the most popular beverages consumed," said lead researcher Samantha Gardener, a post-doctoral research fellow at Edith...
Physiotherapist David Putrino was working on a vibrating glove to help deaf people experience live music when a friend mentioned that the same technology might stop tremors in people with Parkinson's disease.
Putrino, director of rehabilitation innovation for Mount Sinai Health System in New York City, was intrigued. The friend's father had Parkinson's, so they placed the new device on hi...
Neurologists must make sure Alzheimer's patients and their families understand that the controversial drug aducanumab does not restore mental function, the American Academy of Neurology (AAN) said in new position statement that includes ethical guidelines.
"Aducanumab is not a cure for Alzheimer's disease, yet since it has been approved by the [U.S. Food and Drug Administration], patients...
A new and expensive Alzheimer's drug called Aduhelm is responsible for about half of the $21.60 increase in monthly premiums for Medicare's Part B outpatient program in 2022, Medicare officials report.
The new premium will be $170.10 a month, and the $21.60 boost is the biggest increase ever in dollar amount, but not in percentage terms. As recently as August, a smaller increase of $10 fr...
Eating lots of fruits, veggies, beans and other foods with inflammation-cooling properties may lower your odds of developing dementia as you age.
But, if your diet is loaded with pro-inflammatory foods, you may be up to three times more likely to experience memory loss and issues with language, problem-solving and other thinking skills as you age, new research suggests.
A key to reduced Alzheimer's disease risk in women could be how much of the hormone estrogen they're able to stockpile over the years, new research suggests.
Certain lifetime choices — such as having more children, taking hormonal birth control or taking hormone therapy during menopause — mean that a woman has greater cumulative exposure to estrogen during her lifetime. A longer ...
An experimental gene therapy to boost the effectiveness of the Parkinson's drug levodopa yielded promising results in mice, researchers report.
As the loss of dopamine-releasing neurons advances in late-stage Parkinson's, levodopa is less able to ease movement problems caused by the disease, which is a progressive disorder of the nervous system.
Researchers may have unearthed a surprising risk factor for often-fatal brain bleeds: Sleepless nights.
In a study of about 70,000 adults, researchers found that people with a genetic predisposition to insomnia were at somewhat higher risk of a brain aneurysm. An aneurysm is a weak spot in an artery wall that bulges out and fills with blood. In some cases, it can rupture and cause life-th...
When Tommy Van Brocklin signed up for a trial of a special type of magnetic brain stimulation therapy that could potentially ease his depression, he had already been living with the mood disorder for 45 years.
Van Brocklin, 60, first underwent an MRI that located the part of his brain that regulates executive functions such as problem-solving and inhibits unwanted responses.
Researchers may have found a noninvasive way to temporarily open the brain's borders to allow tumor-fighting medication inside.
By necessity, the brain is shielded by a layer of specialized cells called the blood-brain barrier. Its job is to allow needed substances in -- like oxygen and sugar -- while keeping out substances that could be toxic.
Imagine battling debilitating depression for years, trying everything but finding little or no relief.
That's what Sarah, 36, lived with most of her adult life.
"I had exhausted all possible treatment options," recalled Sarah, who did not want her last name used. "It [depression] had controlled my entire life. I barely moved. I barely did anything. I felt tortured every day."
