The blood-brain barrier is a natural membrane that protects your brain from toxins and germs.

Unfortunately, this barrier also hampers the delivery of important medicines and therapies into the brain.

But researchers now think they’ve figured out a way to get drugs past the blood-brain barrier.

A Mount Sinai research team delivered genetic therapies into the brains of mi...

Men with heart risk factors tend to lose their brain health more quickly than women with similar heart risks, a new study finds.

These men face brain decline as early as their mid-50s, while women are most susceptible from their mid-60s onward, researchers report in the Journal of Neurology Neurosurgery and Psychiatry....

People in Southern California with relatively high exposures to wildfire smoke over a decade also had significantly higher risks for dementia, a new study warns.

In fact, the fine-particle pollution created by these fires seems more closely tied to brain trouble than similar pollutants from factories and car exhaust, the researchers noted.

Over the long-term, every one-microgram-pe...

People whose genes put them at high risk for dementia may be able to fight Mother Nature and win, new research out of Sweden suggests.

The weapon: Working out on a regular basis to improve cardiorespiratory fitness, also known as CRF. 

CRF is the c...

WEDNESDAY, Nov. 20, 2024 (HealthDay News) -- A type 2 diabetes diagnosis before age 50 comes with a health risk that patients might not expect.

Especially if they are obese, these folks are more likely to develop dementia later, new research warns.

"Our study suggests that there may be a cognitive consequences to earlier onset type 2 diabetes, and it points to the need for stra...

Dementia strikes all races, but new research suggests thinking declines in poor seniors are often overlooked.

Among a group of more than 200 low-income patients who were treated at community health centers, 3 of 4 had undiagnosed cognitive issues, researchers reported recen...

Seniors who are drowsy during the day and find it hard to muster enthusiasm for activities could be at higher risk of a brain condition that precedes dementia, a new study warns.

These sleep-related problems are associated with "motoric cognitive risk syndrome," a pre-demen...

In 1972, Britain bumped up the total school years mandated for its children from 15 to 16 years.

That created a "natural experiment": Would Britons who got that extra year of education fare any better, neurologically, as they aged?

Unfortunately, the answer is "no."

"This surprised us," said study co-author and brain researcher Nicholas Judd

Sleep apnea appears to increase a person's odds of developing dementia, a new study finds.

The effect seems stronger among women compared to men, noted a research team from the University of Michigan.

Luckily, there are treatments available to help ease sleep apnea, noted study lead author Dr. Tiffany Braley

Folks with more money and better education are at less risk for developing dementia as they grow older, a new study shows.

People with advantaged backgrounds are less likely to develop mild cognitive impairment, and to progress from there to dementia, researchers found.

They also have a better chance ...

Find it hard to take time to exercise during your busy workweek?

No problem, a new study says -- one or two “weekend warrior” workouts are just as likely to help you maintain your brain health.

People who regularly exercise, whether solely on the weekend or thro...

Add Alzheimer’s disease to the list of conditions that might benefit from the revolutionary diabetes drug Ozempic, a new study says.

People with type 2 diabetes taking semaglutide appeared to have a significantly lower risk of developing Alzheimer’s compared to patients taking seven other diabetes drugs, researchers reported...

If you're in your 40s or 50s and have trouble getting and staying asleep, that's not a good sign for brain health as you age, new research suggests.

“Our study, which used brain scans to determine participants’ brain age, suggests that poor sleep is linked to nearly three years of additional brain aging as early as middle age," said study lead author
