Adults use a special part of their brain to solve tough problems. Now, new research shows that kids do the same.

Scientists used brain scans and challenging work to assess how kids and adults might work through these tough problems and whether or not their problem-solving processes were the same.

Turns out they were.

The researchers found that while the multiple demand network...

Using a "neuroprotectant" drug alongside the standard surgical removal of a clot may slash the risk of death and disability following a stroke, a new study finds.

The new medication, called ApTOLL, shields brain tissue from continuing damage by cooling down inflammation, the researchers said.

A stroke occurs when blood supply to part of the brain is blocked by a clot or when a ...

Many football fans fondly remember Rick Arrington as the Philadelphia Eagles' quarterback from 1970 to 1973, but his daughter’s memories are tainted by years spent watching her dad suffer from late-stage chronic traumatic encephalopathy (CTE).

A degenerative brain disease found in athletes, military veterans and others with a history of repetitive brain trauma, CTE causes depression, su...

Parents in the United States may assume baby food is free of impurities, but a recent research review highlights the much different reality: Most foods made for babies and toddlers have some amount of toxic heavy metals.

The contaminants include metals, such as lead and arsenic, that can harm brain development, and contribute to learning and behavior problems in children. And they are fou...

People who live near traffic noise, especially when it continues at night, are more likely to develop the repetitive whistling or buzzing sounds in their ears known as tinnitus.

Danish researchers found a link between the risk of developing the condition and traffic noise, with a vicious cycle of stress reactions and sleep disturbance as a potential cause.

Living near a busy road m...

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.

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.
