Show your baby your love, and you'll get a kinder, gentler adult child as your reward, a new study suggests.

More than 20 years ago, researchers in Israel began studying the impact on newborns of time spent in physical contact with their mothers.

The investigators followed these infants, born in the mid- to late-1990s, for two decades.

Now, their latest results -- based on n...

School-age children with autism may be faring better than commonly thought, with most "doing well" in at least some aspects of development, a new study suggests.

The study, of 272 children with autism spectrum disorder (ASD), found that nearly 80% were doing well in at least one of five developmental areas by age 10. Nearly one-quarter were doing well in four of those areas.

The res...

Long-term organ damage appears to be common in hospitalized COVID-19 patients after they've recovered and been discharged, British researchers report.

One U.S. expert who read over the report said she's seen the same in her practice.

"This study proves that the damage done is not just to the lungs, but can affect the heart, the brain and the kidneys, as well," said Dr. Mangala Naras...

COVID-19 can harm multiple organs in the body, including the brain. Now, a new study says some hospitalized COVID-19 patients have non-convulsive seizures that may increase their risk of death.

"Seizures are a very common complication of severe critical illness. Most of these seizures are not obvious: Unlike seizures that make a person fall down and shake, or convulse, seizures in critica...

Brain activity increases when you start to learn a new language, but slows down as you become more proficient, a new, small study finds.

"In the first few months, you can quantitatively measure language-skill improvement by tracking brain activations," study co-author Kuniyoshi Sakai, a neuroscientist at the University of Tokyo, said in a school news release.

The study included 15 n...

Middle-aged folks who feel persistently lonely appear to have a nearly doubled risk of developing dementia or Alzheimer's disease, a new study reports.

If you take steps to counter your loneliness, however, you might actually reduce your dementia risk, the researchers found.

Dementia risk rose 91% in those who reported feelings of loneliness that persisted across two separate health...

When people die some cells in their brains go on for hours, even getting more active and growing to gargantuan proportions, new research shows.

Awareness of this activity, spurred on by "zombie genes," could affect research into diseases that affect the brain.

For the study, researchers analyzed gene expression using fresh brain tissue collected during routine surgery and found that...

The brain may play a role in so-called broken heart syndrome, a new study suggests.

Formally known as Takotsubo syndrome (TTS), it's a temporary -- but potentially deadly -- heart condition brought on by stressful situations and emotions.

In this study, published March 25 in the European Heart Journal, researchers wanted to find out if increased stress-associated metabolic ...

Regular aerobic exercise increases blood flow to the brain, which may help slow mental decline in older adults, a new, small study suggests.

Researchers from University of Texas Southwestern Medical Center looked at 70 men and women diagnosed with mild cognitive impairment (MCI). This means there are slight changes to the brain that affect memory, decision-making or reasoning skills. In m...

It's not unusual for a fictional character to ring such a chord that their story shapes your life.

Think of educators inspired by Robin Williams' character in "Dead Poets Society," lawyers drawn to the profession by Perry Mason or Atticus Finch, or health professionals motivated by the doctors on "ER" or "Grey's Anatomy."

Now researchers think they've figured out why fiction can so ...

People really do vary in how fast they age, and the divergence starts in young adulthood, a new study suggests.

The researchers found that by the tender age of 45, people with a faster pace of "biological aging" were more likely to feel, function and look far older than they actually were. And that relative sprint toward old age began in their 20s.

The findings, the study authors sa...

For someone suffering a severe stroke, every 10 minutes that goes by before treatment starts in the emergency room may cost eight weeks of a healthy life, Canadian researchers report.

In fact, delays in the hospital may have worse consequences for recovery than delays in getting to the hospital, they noted.

"Our study confirmed that any delay in delivering appropriate stroke treatme...

It's already being taken by millions to help ward off heart issues, and now preliminary research hints that daily low-dose aspirin might also cut your odds of contracting COVID-19.

As the Israeli research team noted, aspirin is an anti-inflammatory and previous studies have shown that it may help the immune system combat some viral infections. According to the researchers, aspirin was wid...

About 7 out of 10 Alzheimer's patients wound up free of the brain plaques that are a hallmark of the disease after treatment with a potentially breakthrough experimental drug, clinical trial results show.

The drug, donanemab, also significantly slowed the patients' brain decline, according to findings published March 13 in the New England Journal of Medicine.

Donanemab diss...

Many people dread the switch to daylight saving time. When you're losing an hour of sleep, it can be hard to actually feel like springing forward.

Dr. Rachel Ziegler, a sleep medicine physician from the Mayo Clinic Health System in Fairmont, Minn., offers some tips for easing into the time change before it happens on March 14.

Ziegler recommends getting to bed 15 minutes early now, ...

Your eyes may be a window into the health of your brain, a new study indicates.

Researchers found that older adults with the eye disease retinopathy were at increased risk of having a stroke, as well as possible symptoms of dementia. And on average, they died sooner than people their age without the eye condition.

Retinopathy refers to a disease the retina, the light-sensing tissue ...

Sustaining just one head injury may up your chances of developing dementia decades later by 25%, and this risk increases with each subsequent head injury, new research suggests.

"Head injury is not the only risk factor for dementia as high blood pressure and diabetes, among others, also contribute significantly to dementia risk, but head injury is one risk factor for dementia that is modi...

A new type of surgery offers amputees better control of muscles that remain after surgery, and of their prosthetic limbs, its inventors say.

The standard surgical approach to amputation has changed little since the American Civil War, according to developers of the new approach. In their small study, the new procedure also helped curb pain and sensations like the troubling "phantom limb" ...

Concussions can increase the long-term risk of a wide range of sleep disorders, a new study indicates.

Researchers looked at more than 98,700 U.S. veterans diagnosed with a traumatic brain injury (TBI) and the same number of veterans with no history of TBI. The brain injuries ranged from mild TBI (concussion) to severe.

None of the participants had sleep disorders at the start of th...

Doctors are testing a decades-old surgical technique as a new way to treat certain stroke patients. And the preliminary results look promising, they say.

At issue are strokes caused by intracranial atherosclerosis, where blood vessels within the brain become hardened and narrowed.

Strokes occur when the blood supply to the brain is disrupted, depriving tissue of oxygen and nutrients...

The position played in sports like football and hockey isn't associated with risk of a concussion-linked brain disease later in life, a new study suggests.

The number of years played doesn't affect risk of the neurodegenerative disease -- chronic traumatic encephalopathy (CTE) -- either, researchers found.

CTE has been linked with repeated blows to the head. Symptoms include behavio...

Helping your brain stay sharp with age may be as simple as changing up the food on your plate at dinnertime, a new study suggests.

The study focused on the healthy "Mediterranean" diet, a regimen reliant on olive oil, beans, nuts, fruits, vegetables and whole grains, with chicken and fish largely replacing red meat. Dairy products and eggs are only used in "low to moderate amounts," accor...

Researchers may have uncovered a key reason some people remain sharp as a tack into their 80s and 90s: Their brains resist the buildup of certain proteins that mark Alzheimer's disease.

The study focused on what scientists have dubbed "super agers" -- a select group of older folks who have the memory performance of people decades younger.

Compared with older people who had average b...

It's been nearly a year since David Speal, 38, first fell ill with COVID-19, but a racing heartbeat remains a regular reminder of his brush with the new coronavirus.

Even the littlest thing -- not eating at the right time, not drinking enough water, too much exercise, a stressful encounter -- can send Speal's heartbeat soaring as high as 150 beats per minute.

"My autonomic nervous s...

The link between heart-lung fitness and brain health may begin at an early age, new research shows.

The study revealed that 4- to 6-year-olds who could walk farther during a timed test also scored higher on tests of thinking abilities and other measures of brain function.

Most studies of the link between brain health and heart-lung ("cardiorespiratory") fitness have focused on older...

Many patients with mild to moderate COVID-19 could become "long haulers," suffering symptoms months after they clear their non-life-threatening infection, new research shows.

About 33% of COVID-19 patients who were never sick enough to require hospitalization continue to complain months later of symptoms like fatigue, loss of smell or taste and "brain fog," University of Washington (UW) r...

White matter damage in the brains of adults with frontotemporal dementia is even greater than that seen in Alzheimer's disease patients, a new study shows.

Frontotemporal dementia often affects people younger than 65, mainly causing personality and behavior changes and problems with language, rather than memory. The researchers assessed areas of brain damage called white matter hyperinten...

If you've ever had a "lucid dream" -- one in which you're aware you're dreaming -- new research just might jolt you awake.

Not only is it possible during these vivid dreams to perceive questions, but to answer them, too -- at least sometimes.

That's the tantalizing takeaway from four independent studies that used different methods to communicate with sleeping volunteers, including s...

Older adults who get little sleep each night may be at heightened risk of dementia or earlier death, a new study suggests.

Researchers found that among 2,600 older Americans, those who were deemed "short sleepers" -- catching no more than five hours of sleep at night -- were more likely to develop dementia or die over the next five years.

Their risks were double that of older people...

One of the least understood effects of COVID-19 infection is "brain fog," a kind of mental confusion that can take hold among seriously ill patients, sometimes lingering long after recovery.

Now, a new study has spotted a possible neurological clue in the form of highly unusual cell clusters in the brains of people who had COVID-19.

"What we're talking about is a situation where pat...

"Prediabetes" -- where blood sugar levels are high but not yet tipped over into full-blown diabetes -- may pose a threat to brain health, new British research suggests.

"As an observational study, it cannot prove higher blood sugar levels cause worsening brain health. However, we believe there is a potential connection that needs to be investigated further," said study lead author Victori...

Older men whose blood pressure rises at night may be at increased risk for Alzheimer's disease, a new study suggests.

Blood pressure changes over 24 hours. It typically goes up during the day and dips at nighttime. But some people have an opposite pattern, which is called reverse dipping.

"The night is a critical period for brain health. For example, in animals, it has previously be...

Living in a noisy neighborhood with less green space negatively affects teens' sleep, which may lead to poorer memory and thinking skills, according to a pair of studies.

In a study on residential environment, researchers found that as noise levels steadily increased, so too did the time needed for teens to fall asleep. They also didn't sleep as long as kids in quieter, greener neighborho...

Stroke survivor Ken Allsford focused intensely on how he wanted to bend his elbow.

And then the robot exoskeleton attached to his left arm obeyed his unspoken command, moving his crippled limb.

"It was a combination of exciting and trepidation, because sometimes nothing would happen," Allsford, 61, of Katy, Texas, recalled. "But when you actually see it move without actually making ...

Medical science has come a long way since the days of "bikini medicine," when the only time doctors managed a woman's health differently than a man's was when treating the parts of her body found under a bikini.

Over the past few decades, researchers have uncovered countless ways in which women's and men's bodies react differently to the same diseases. And just as it's now widely recogniz...

Why does one person take a lot of risks and another proceed with more caution?

Researchers came closer to that answer with a new study that shows risk-taking behavior may be related to characteristics in the brain.

The study found there is no one risk area in the brain. Instead, there are many regions where anatomy is altered in people who take risks. Yet there is a connection bet...

Enlarged spaces in the brain that fill with fluid around small blood vessels may be a harbinger of impending dementia, a new Australian study suggests.

Typically, these so-called perivascular spaces help clear waste and toxins from the brain and might be linked with changes in the aging brain, researchers say.

"Dilated perivascular spaces, which are a common MRI finding, especi...

Think your dog is smart? New research suggests one way to find out.

Most dogs can't learn words without extensive training, but a few with exceptional abilities learn words without any formal training, researchers report. They learn words simply by playing with their owners.

The team of Hungarian researchers investigated how quickly two of these talented pooches could learn new word...

Too much screen time can make your toddler more distractible, British researchers warn.

The use of smartphones and tablets by babies and toddlers has soared in recent years.

"The first few years of life are critical for children to learn how to control their attention and ignore distraction, early skills that are known to be important for later academic achievement," said lead autho...

While researchers continue to try to find the key that unlocks the cause of Parkinson's disease, new research suggests that what a person eats could make a difference.

Researchers in Canada found a strong correlation between eating either a Mediterranean diet or the MIND diet (which combines elements of the Mediterranean diet and a diet known as Dietary Approaches to Stop Hypertension), a...

TUESDAY, Jan. 26, 2021 (HealthDay News) - - "You snooze, you lose" may not be true when it comes to your brain: A new study finds that napping in the afternoon may actually boost mental agility.

The study couldn't prove cause and effect, but a midday nap was associated with a rise in "locational awareness," verbal fluency and working memory, the Chinese researchers reported Jan. 25 in the...

Researchers have found a way to track what your mind is doing when thoughts begin to wander.

Using electroencephalograms (EEG) to measure brain activity while more than two dozen study participants did mundane attention tasks, the researchers identified brain signals associated with a daydreaming mind.

They found that the participants had increased alpha brain waves in the prefronta...

Noninvasive electrical stimulation of the brain, fine-tuned to specific "circuitry" gone awry, might help ease obsessive-compulsive behaviors, an early study hints.

Researchers found that the brain stimulation, delivered over five days, reduced obsessive-compulsive tendencies for three months, though in people who did not have full-blown obsessive-compulsive disorder (OCD).

It's too...

A study that examined how people walked through doorways provides new insight into anorexia's effect on a person's body image.

It's long been known that people with anorexia overestimate their body size, but this study examined unconscious body awareness -- formally called "body schema." It's the innate ability a person has to orient themselves in a room and stop from bumping into objects...

A rare brain disease that causes loss of language skills doesn't lead to memory loss, a new study finds.

The condition is called primary progressive aphasia and about 40% of people who have it have underlying Alzheimer's disease, according to researchers. Their study was published online Jan. 13 in the journal Neurology.

"While we knew that the memories of people with prima...

New research offers a novel explanation for the long-term brain problems many COVID-19 patients experience.

Many coronavirus patients report headaches and "brain fog" for weeks or months after they recover from respiratory symptoms. It's been believed that these lingering neurological issues are the result of nerve cell damage, but the new study suggests that the virus may instead be stri...

Brain drain: Arguing with others puts a lot more strain on your brain than agreeing with them, a new study finds.

"Our entire brain is a social processing network," said senior author Joy Hirsch, professor of psychiatry, comparative medicine and neuroscience at Yale University. "However, it just takes a lot more brain real estate to disagree than to agree."

The researchers, from Ya...

Moderate-to-vigorous physical activity in middle age and beyond might help keep your brain healthy, a new study suggests.

"Our study suggests that getting at least an hour and 15 minutes of moderate-to-vigorous-intensity physical activity a week or more during midlife may be important throughout your lifetime for promoting brain health and preserving the actual structure of your brain," s...

A new study supports the theory that people who suffer a spinal cord injury may also have accelerated brain aging that affects how fast they process information.

Those "cognitive deficits" are similar to those in older adults, according to research from the nonprofit Kessler Foundation in New Jersey.

Individuals with chronic spinal cord injury (SCI) have an increased risk for cognit...

Despite training that teaches police officers to use neck restraints, there is no medical justification for the tactic, three neurologists write in JAMA Neurology.

The killing of George Floyd, who died in May 2020 after an arresting police officer pressed a knee to his neck for more than eight minutes, helped spark a nationwide conversation about racial injustice.

While Fl...
