Mindfulness training may help counter the thinking and emotional difficulties caused by multiple sclerosis.

In a small test study, people with multiple sclerosis (MS) who had four weeks of mindfulness training emerged with better emotional control and faster thinking.

Multiple sclerosis is a disease in which the immune system attacks the brain, spinal cord and optic nerves....

Preventing heart disease may protect you from dementia, researchers say.

The new study looked at nearly 1,600 people, at an average age of 79.5, who were followed for 21 years. Their heart disease risk was assessed at the outset, and participants had annual memory and thinking tests.

The takeaway: People with a higher risk of heart disease also had greater mental (cognitive)...

Ordering a cheeseburger and fries might literally be a dumb move, new research suggests.

A recent, small study from Ohio State University indicates eating a single meal high in saturated fats may hamper your ability to mentally focus.

Saturated fats are found in red meat, dairy products and tropical oils, including coconut and palm. They can raise cholesterol and clog arter...

Want to give your brain a boost? Go for a swim, take a walk, or spin your partner on the living room floor.

A new study finds that aerobic exercise can improve older adults' thinking and memory, even if they're longtime couch potatoes.

This type of exercise increases blood flow to the brain and counters the effects of normal aging, according to the study published online May...

Memory and thinking skills are generally worse after a stroke for people with type 2 diabetes compared to people with normal blood sugar levels or prediabetes, new research suggests.

"We found that diabetes, but not prediabetes, is associated with poorer cognitive performance in every aspect of cognition tested," said study lead author Jessica Lo. She's a research associate from the ...

Researchers may have gained new insights into a mystifying condition that causes children's behavior to change so severely and abruptly, it can be like they woke up as a different person.

The condition is known as pediatric acute-onset neuropsychiatric syndrome, or PANS. It is diagnosed when a child has a dramatic -- sometimes overnight -- onset of psychiatric and neurological symptom...

Toddlers with congenital Zika syndrome have severe developmental delays, researchers report.

In a study that covered a five-year period, researchers found that children in Brazil with congenital Zika syndrome who had microcephaly at birth suffered severe mental delays.

Microcephaly is a condition in which the head is smaller than normal. Its severity was the only significa...

Babies who have disrupted sleep, as many with autism do, may experience delayed brain development, a new study suggests.

Sleep problems in baby's first year may affect growth of the hippocampus and may also precede an autism diagnosis, researchers say.

In the study of 400 6- to 12-month-old infants, the investigators found that those diagnosed with autism were more likely ...

If you've ever wondered what your brain is doing while you sleep, a new study gives the first direct evidence that it's busy "replaying" our waking experiences.

The finding comes from a research project called BrainGate, which is testing new technology for people who are paralyzed or have lost a limb. Participants have "micro-electrodes" implanted in their brains, to allow them to exe...

People who've recently had a heart attack show increased activity in the area of the brain involved in stress and emotions. And this is associated with elevated inflammation in arteries, a small, preliminary study finds.

"The results of this study advance our understanding of the interconnections among the brain, bone marrow and blood vessels," said study lead author Dr. Dong Oh Kang,...

Love to cuddle up? It might bring a 'mind meld,' too, new research shows.

People in close physical contact appear to have synchronized brain patterns, a revolutionary new MRI technique has revealed.

A functional MRI scan of two people cuddling under a blanket showed that their brains appeared to be falling into similar patterns of action and response, as they took turns gent...

The brain damage that may occur in football players has received a lot of attention in recent years. But a new study suggests that former players who get a diagnosis of chronic traumatic encephalopathy (CTE) when they're still alive may well be getting the wrong diagnosis.

CTE can only be diagnosed with an autopsy, the researchers explained. Other conditions could cause the symptoms ...

Rising levels of greenhouse gases may do more than drive climate change, they may eventually impair your thinking, researchers warn.

Carbon dioxide (CO2) levels tend to be higher indoors than outdoors. As CO2 concentrations increase in the atmosphere, there will be higher levels of the gas indoors, possibly triggering significant declines in people's decision-making skills and strate...

Letting a baby watch a smartphone, tablet or TV at 12 months increases the odds the child will develop autism-like symptoms during the next year, new research suggests.

On the other hand, if parents spent active play time with their child every day, the odds of autism-like symptoms decreased.

"At 12 months, watching TV or DVDs was associated with more autism symptoms a...

Nighttime high blood pressure could harm the brain, a new study says.

Most people's blood pressure goes down during the night, which is called dipping. But in some people, it stays the same or even rises -- called reverse dipping.

Folks with high blood pressure and reverse dipping may be at increased risk for vascular damage in the brain and associated memory problems, accor...

Long periods of time in space may cause brain volume increases in astronauts, new research shows.

Extended periods in space have long been known to cause vision problems. And more than half of International Space Station crew members have reported vision changes.

Increased pressure inside the head might contribute to vision problems, scientists have suggested.

To l...

Even before symptoms develop, the brains of people with early Alzheimer's disease have high levels of amyloid protein plaques, a new study reveals.

Those levels in older adults with no dementia symptoms are associated with a family history of disease, lower scores on thinking/memory tests, and declines in daily mental function.

The first findings from the so-called A4 study ...

A study out of China finds that strokes, altered consciousness and other neurological issues are relatively common in more serious cases of COVID-19.

Looking at 214 cases of severe coronavirus illness treated in Wuhan city during the early phase of the global pandemic, doctors reported that 36.4% of patients displayed neurological symptoms.

Sometimes these symptoms appe...

Intensifying a standard form of brain stimulation may bring relief to people with hard-to-treat depression, a preliminary study suggests.

The study involved just 21 patients, but the treatment sent 90% into remission within a few days. That's a success rate that has never been seen in early testing of other therapies for severe depression, the researchers said.

The thera...

A new study dispels a common belief about how stimulants such as Ritalin and Adderall work in the brain.

The drugs are usually prescribed to people with attention deficit hyperactivity disorder (ADHD), but are sometimes used by otherwise healthy people to boost their thinking.

Many assume these drugs improve focus, but researchers found that they actually get the brain to e...

Smog drives up dementia risk, particularly for older men and women with heart disease, according to a new Swedish study.

For more than a decade, researchers tracked exposure to air pollution and dementia cases among nearly 3,000 Stockholm residents aged 60 and up.

Lead author Dr. Giulia Grande noted that exposure to dirty air has long been linked to an increased risk for lun...

Millions of Americans pop a low-dose aspirin each day to help ward off heart issues, but a new study finds that protection may not extend to dementia.

Although the anti-inflammatory effects of aspirin have been touted as protection against thinking and memory (or "cognitive") problems from Alzheimer's and other dementias, a large, randomized trial suggests aspirin won't slow mental de...

New research out of France suggests that untreated sleep apnea could raise your odds for developing Alzheimer's disease.

Evidence linking the two is based on a series of neurological assessments, brain scans and sleep analyses conducted between 2016 and 2018.

"This is further support of Alzheimer's as a lifestyle chronic condition that results from a lifetime of experiences,...

Brain inflammation may be more of a factor in dementia than previously believed, a new British study suggests.

"We predicted the link between inflammation in the brain and the buildup of damaging proteins, but even we were surprised by how tightly these two problems mapped on to each other," said co-author Thomas Cope of the Department of Clinical Neurosciences at the University of Ca...

Padded helmets and safe tackling and blocking techniques can reduce the chance of head injuries for middle school football players, a new study finds.

Young athletes make up 70% of America's amateur and pro football players. As head injuries in older athletes have been linked to a slew of brain injuries, attention is now turning to the safety of the younger players.

Your morning cup of coffee may help your focus and problem-solving skills, but it won't kick-start your creativity, a new study says.

"In Western cultures, caffeine is stereotypically associated with creative occupations and lifestyles, from writers and their coffee to programmers and their energy drinks, and there's more than a kernel of truth to these stereotypes," said study first ...

Your knee might never be the same after undergoing surgery for a torn anterior cruciate ligament (ACL), and the reason is in your head, a small, new study suggests.

It turns out ACL reconstruction causes changes in the structure of your brain, a University of Michigan (U-M) team found. That's why even after ACL reconstruction and physical therapy, your joint function might never get b...

Few heartbreaks are as devastating as when a beloved family dog falls ill with cancer.

But a new research paper could spur development of more and better treatments for a canine companion who has a brain tumor -- because it's possible that those same therapies will help human kids, too. Dogs' brain cancers are genetically akin to those found in children, a new study in the journal ...

Take a walk, weed your garden, go for a swim or dance -- it could keep your brain from shrinking as you age, a new study suggests.

Being physically active may keep your brain four years younger than the rest of you, which might help prevent or slow the progression of dementias like Alzheimer's disease, researchers say.

"We recently published a paper using information of bo...

A healthier heart in early adulthood could mean fewer thinking and memory problems later in life, a new study suggests.

"These results indicate that people need to pay close attention to their health even in their early 20s," said study author Dr. Farzaneh Sorond, of Northwestern University School of Medicine in Chicago.

Sorond and her team conducted a 30-year study of 189 p...

A noninvasive magnetic brain stimulation device worn less than an hour a day can increase activity near stroke-injured areas of the brain, a small, preliminary study suggests.

Those improvements in brain activity might then lead to increased motor function in people who have had a stroke, the researchers said.

"We were excited to see a strong hint of improved motor functio...

For decades, artery-opening stents have helped prevent heart attacks, and new research suggests they might also help prevent strokes in the brain.

In a new study, the self-expanding, intracranial Wingspan brain stent seems effective over the long term in reducing stroke patients' risk of a subsequent stroke and death.

Intracranial stents are tiny mesh tubes that are permanen...

Bleeding strokes are the deadliest type of stroke and the hardest to treat. What might make matters worse is having both diabetes and Alzheimer's disease versus either condition alone, new research shows.

The study looked at 2,071 adults in the Kentucky Appalachian Stroke Registry who had a hemorrhagic stroke. The researchers reviewed each patient's health records to look for a previ...

Adults with glioblastoma -- the most common and deadly type of brain tumor -- could survive more than twice as long if surgeons removed surrounding tissue as well as the tumor, a new study finds.

That involves cutting out "non-contrast-enhancing tumor" -- which doesn't light up on an MRI when a contrast agent is injected -- as well as contrast-enhancing tumor.

"Traditionally...

A breakthrough study has identified a class of natural gene variants that may protect against Alzheimer's disease.

For the study, researchers at University College London analyzed DNA from more than 10,000 people -- half with Alzheimer's and half without. The investigators found that these gene variants reduce the functioning of proteins called tyrosine phosphatases.

These p...

People who develop Parkinson's disease at a younger age (before age 50) may have malfunctioning brain cells at birth, according to a study that also identified a drug that may help these patients.

At least 500,000 people in the United States are diagnosed with Parkinson's each year. Most are 60 or older at diagnosis, but about 10% are between 21 and 50.

Parkinson's is ...

A new discovery could lead to better treatments for multiple sclerosis (MS) and other autoimmune diseases, such as psoriasis and rheumatoid arthritis, researchers report.

MS occurs when immune cells get into the central nervous system (the brain and spinal cord), causing nerve damage that results in neurological problems. However, the cause is unclear.

Studies in a mouse mo...

Most people take the ability to move for granted, but not Kathy Miska.

Miska has had multiple sclerosis for two decades now, and her ability to get around has deteriorated steadily.

Now, a new robotic exoskeleton is giving her an opportunity to regain some of the mobility she's lost to the degenerative nerve disease.

"You can definitely tell when you get out of the suit....

Many mothers-to-be feel overwhelmed by stress, and it might have implications for their babies' brain development in the womb, a new study suggests.

The researchers found that even in a group of highly educated, healthy pregnant women, stress and anxiety were common. More than one-quarter reported higher-than-average levels of "perceived stress," while a similar number had anxiety sym...

Older adults who regularly consume a group of antioxidants called flavonols may have a decreased risk of developing Alzheimer's disease, a new study suggests.

The compounds exist in many fruits and vegetables, with the richest sources including green vegetables like kale, spinach and broccoli, apples and tea.

The researchers found that of over 900 older adults they followed ...

A single dose of the psychedelic ingredient in "magic mushrooms" may bring long-lasting relief to cancer patients who suffer anxiety and depression, a new, small study suggests.

Researchers found that of 15 patients who'd received a one-time treatment with psilocybin, most were still showing "clinically significant" improvements in anxiety and depression four years later.

Th...

A gene mutation implicated in the risk for Alzheimer's disease might also impair memory in soccer players who head the ball a lot, a new study suggests.

The finding could have implications for young athletes in contact sports where the head can take hits during play.

Among soccer players who headed the ball the most, those with the gene mutation called the apolipoprotein E ...

When it comes to parts of your brain, bigger isn't necessarily better.

Experts long believed that a bigger hippocampus meant better memory. But new research finds that the size of this seahorse-shaped structure deep in the brain doesn't always predict learning and memory abilities.

Researchers looked at more than 330 older adults in Germany and found that a larger hippocampu...

After a hemorrhagic stroke, often called a "bleeding" stroke, young black and Hispanic people are less likely than white people to be disabled or die within the following three months, a new study finds.

Hemorrhagic strokes occur when a blood vessel ruptures, causing bleeding in the brain. This type of stroke is less common than ones caused by blood clots, but harder to treat and mor...

Kertisha Brabson's mom rushed to the hospital after being told her adult daughter was acting out of her mind.

"She was talking out of her head, dancing like she was at a concert," recalls Kertease Williams. "She was trying to get out of the room. They had to have a nurse in her room around the clock because she would try to leave."

Neither woman could know it, but this incid...

Dementia patients may develop distinct speech and reading problems depending on their native language, a new study finds.

The study included 20 English-speaking and 18 Italian-speaking patients with primary progressive aphasia (PPA), a neurodegenerative disorder that affects language areas in the brain. It is often associated with dementia.

The patients had a type of PPA cha...

Shallower-than-normal brain waves may play a role in serious sleep problems in children with autism, a new study suggests.

Previous research has shown that between 40% and 80% of children with autism have sleep issues, such as trouble falling asleep or waking frequently during the night and rising early. These problems can be significant challenges for the children and their f...

Hearing that your unborn baby has congenital heart disease can be traumatic, but now new research suggests that if you experience stress, anxiety or depression afterward it could affect your baby's brain development.

Congenital heart disease (structural problems with the heart) is the one of the most common birth defects.

"We were alarmed by the high percentage of pregnant w...

Severe deprivation in childhood can lead to a smaller-than-normal brain, lower IQ and attention deficits in early adulthood, a new study suggests.

Researchers analyzed MRI brain scans of 67 young adults, ages 23 to 28, who were institutionalized as children in Romania during the Communist regime. They had spent between 3 and 41 months in institutions, where they were often malnourishe...

Poor sleep has been linked to the development of dementia and Alzheimer's disease, and now a new study suggests a possible reason why.

A small group of young, healthy men deprived of just one night of sleep had higher blood levels of tau protein than when they had a full and uninterrupted night of rest, researchers reported in a study published online Jan. 8 in Neurology.
