Taking good care of your teeth -- brushing, flossing, regular dental checkups -- is, of course, important for good health. Now researchers say it's also vital for brain health.

While it was already clear that poor dental health could increase stroke and heart disease risk, a new study funds that adults who are genetically prone to have cavities, dentures and missing teeth are also more li...

If you find yourself stuck in a traffic jam and you start to feel fuzzy-headed, the diesel exhaust from the truck in front of you might be to blame.

New research found that just two hours of exposure to diesel exhaust impaired the brain’s functional connectivity, which can lower your ability to think and remember.

"We compared people after diesel exhaust exposure compared to filt...

People who suffer a heart attack or stroke in middle age may develop memory and thinking problems earlier in life, too, a new study finds.

The study, published online Jan. 25 in the journal Neurology, focused on people who had developed premature cardiovascular disease. That refers...

Memory loss is the most common symptom associated with Alzheimer’s disease — the terrifying prospect of slowly forgetting yourself and everything around you.

But people who exhibit memory loss early on in their dementia actually have a slower rate of decline than those who develop other symptoms earlier, a

By the time they're teenagers, babies born prematurely may be getting poorer school grades than their non-preemie peers.

Researchers found that babies born before 34 weeks of pregnancy had lower scores on math and language tests during their teen years compared to kids born at 40 weeks.

However, the study did not find a significant difference in later brain function in babies born b...

Some college athletes take longer to recover from a concussion, but a new study offers them some good news.

They may still be able to return to play -- after one extra month of recovery, researchers report Jan. 18 in the journal Neurology.

"Although an athlete may experience a slow or delayed recovery, there is reason to believe recovery is achievable with additional time ...

A recent study suggests that Parkinson's disease, in which parts of the brain are progressively damaged over many years, may actually start in the gut.

Nearly 30% of the gut bacteria in patients with Parkinson's disease differed from those without the disease, according to the study ...

American adults who have epilepsy and are Black or Hispanic are less likely than white adults to be prescribed the latest medications, according to new research.

“While finding the right medication is often a trial-and-error process that is based on the individual, studies have shown that use of newer medications improves outcomes, and some newer medications have fewer side effects,” ...

Six minutes of high-intensity exercise might prolong the lifespan of a healthy brain, perhaps delaying the start of Alzheimer's and Parkinson’s diseases, a new, small study suggests.

Researchers found that short but intense cycling increased the production of a protein called brain-derived neurotrophic factor (BDNF), which is essential for brain formation, learning and memory. It's tho...

The U.S. Food and Drug Administration on Friday approved a second Alzheimer's drug, lecanemab, despite reports of rare brain bleeds linked to use of the drug in some patients.

However, the FDA pointed to the drug's benefits, as well.

“Alzheimer’s disease immeasurably incapacitates the lives of those who suffer from it and has devastating effects on their loved ones,” Dr. Bill...

Lecanemab: It's an experimental medication that's been shown in trials to slow cognitive decline in people with Alzheimer’s disease.

It's also up for accelerated approval by the U.S. Food and Drug Administration, with a decision expected by Jan. 6.

However, the drug has also been linked to two deaths from brain bleeds among people who’ve used it in trials, so safety concerns c...

Social media's impact on young people is a hot topic, with most kids and teens wanting to do whatever their friends are doing and parents worrying about setting limits.

A new study examines whether frequent checking of social media sites (Facebook, Instagram and Snapchat) is associated with changes in functional brain development in these early adolescents, about age 12.

Those seemingly random kicks or wiggles a newborn baby makes have a purpose.

With each movement, the baby is developing its sensorimotor system, which it will later use to perform sequential movements. The sensorimotor system lets a person control muscles, movement and coordination.

Researchers studying these “spontaneous” newborn movements and comparing them to babies a few mon...

Living in an area with easy access to parks and rivers appears to slow the progression of devastating neurological diseases, such as Alzheimer's and Parkinson's.

One of the hallmarks of a COVID-19 infection has been a lost sense of smell after the infection ends.

In a new study, researchers blame an ongoing immune assault on the olfactory nerve cells — cells found at the top of the nasal cavity — and a decline in the number of those cells. The study was led by a team at Duke Health in Durham, N.C.

“One of the first symptoms that has ty...

If you need another reason to quit smoking, researchers have one: your mid-life brain health.

Not only does smoking harm lung and heart health, but it increases the chances of middle-aged memory loss and confusion, a new study shows.

The likelihood of mental ("cognitive") decline is lower for those who quit — even if they did so only recently, according to researchers at Ohio Sta...

Researchers are studying whether deep brain stimulation could help people with Alzheimer's hold on to their memory longer, and now a new finding may help refine the approach.

Deep brain stimulation (DBS) is an established treatment for several medical conditions, including epilepsy, Parkinson's disease and obsessive-compulsive disorder. It involves implanting electrodes in certain areas o...

Groups of whales, dolphins and porpoises are regularly stranded in shallow waters around the coasts of the United Kingdom.

    Chips, pizza, cookies: Delicious, but a diet full of ultra-processed foods like these may contribute to brain deterioration, researchers report.

    Ultra-processed foods have lots of added and unhealthy ingredients, such as sugar, salt, fat, artificial colors and preservatives. Examples include frozen meals, soft drinks, hot dogs and cold cuts, fast food, packaged cookies, cakes and sal...

    Growing numbers of Americans are suffering prolonged, life-threatening seizures known as status epilepticus, and Black people are nearly twice as likely to experience these seizures as white people.

    These are the main findings from new research looking at hospitalizations for status epilepticus from 2010 to 2019 across the United States. Status epilepticus refers to ...

    Seizures tend to get progressively worse over time in people with epilepsy, and a new study in mice suggests why that might be the case.

    Seizures appear to prompt the brains of mice to produce more myelin, the insulating layer around nerve cells, researchers from Stanford University found.

    This essentially rewires the brain, creating a vicious cycle in which more seizures cause more...

    Finally, more than two years into the pandemic, Americans are sleeping better.

    A new survey from the American Academy of Sleep Medicine (AASM) found that 31% of people have had insomnia since the pandemic began. That was much lower — a 25% decrease — compared to the...

    Two people have now died from brain hemorrhages that may be linked to an experimental Alzheimer's drug, calling into question the medication's safety.
