For people who've suffered through a bout of COVID-19, their misery is too often not over. New research shows that a wide variety of "long-haul" symptoms are common, and the risk rises along with the severity of their case of COVID-19.

In what may be the largest such study to date, "the findings show that beyond the first 30 days of illness, substantial burden of health loss -- spanning ...

Waking up briefly throughout the night may do more than leave you feeling grumpy and tired in the morning.

Disrupted sleep may actually increase your odds of dying early from heart disease or any other cause, and women seem to be harder hit by these effects than men.

"The data underscores all the more reasons why we need to be screening people about whether or not they feel refreshe...

Black and Hispanic survivors of a bleeding stroke are more likely than white survivors to have changes in small blood vessels in the brain that increase the risk of another bleeding stroke, researchers say.

'Bleeding' strokes, also called hemorrhagic stroke, comprise about 13% of all strokes. They occur when an artery in the brain leaks or ruptures.

"While Black and Hispanic bleedin...

Autism appears to develop differently in girls and boys, so the findings of research conducted mainly with boys might not apply to girls, a new study suggests.

Autism spectrum disorder is four times more common in boys, which may help explain why there's far less research about autism in girls.

"This new study provides us with a roadmap for understanding how to better match current ...

As if the headaches and stuffy nose aren't bad enough, chronic sinus trouble often leaves patients foggy-headed and depressed. Now, new research suggests one possible reason why: Sinusitis may trigger changes in brain activity.

"Chronic sinusitis is incredibly common," said study lead author Dr. Aria Jafari. Upwards of 11% of all Americans are affected, added Jafari, an assistant profess...

An emerging technology could zap your post-op pain away -- little or no opioids needed.

A team led by Dr. Brian Ilfeld, of the University of California, ...

Men with certain sleep problems, like sleep walking, may be at a higher risk of developing Parkinson's disease, a new study suggests.

Among nearly 26,000 men, researchers found those who sleepwalked or had rapid eye movement sleep behavior disorder (RBD) had a four times or higher risk of developing Parkinson's disease compared to those who didn't.

"Presence of parasomnia, such as s...

In very rare cases, children infected with the new coronavirus can develop a severe illness known as multisystem inflammatory syndrome (MIS-C). Now, research finds that these young patients often develop neurologic symptoms along with the respiratory issues they might face.

These neurologic symptoms were present in half of children who were hospitalized with MIS-C, U.K. researchers say.

A combination of hearing and vision loss is tied to an increased risk of mental decline and dementia, but having just one of those impairments isn't connected with a higher risk, a new South Korean study finds.

It's not clear why a diminishing of both senses, but not just one, would raise dementia risks, but the study's leader had a theory that's tied to the importance of socializing in ...

Doctors are seeing such cases around the world: About a third of COVID-19 patients go on to develop "long-haul" neurological or psychiatric conditions months after being infected, new research shows.

So, you had COVID-19 a few months back and you still can't smell that first steaming cup of coffee in the morning. Is there anything you can do to hasten the return of that vital sense?

Experts say there is, including "physical therapy" for your nose.

"In most cases, smell loss is temporary, but it can take months or even years to recover," said researcher Dr. Tran Locke. She's an a...

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...

You've had a stroke and arrive at a hospital, but the stroke specialist is off-duty. Never fear: Telemedicine may help save your life.

Especially during the COVID-19 crisis, so-called 'telestroke' services -- where health workers use video to consult with a stroke specialist who could be miles away -- is helping to lead to better patient outcomes, new research shows.

"Our findings p...

Spinal cord injuries can be devastating to the more than 17,000 Americans who suffer them each year. But many patients may have new reason for hope: Early research suggests infusions of stem cells could help them regain lost sensation and movement.

These improvements may occur within days or weeks of receiving the stem cell therapy, and can last at least six months, according to the small...

"Early to bed, early to rise" may be good advice for your career. New research finds that, compared to night owls, folks with earlier bedtimes perform better at work and are less plagued by disabilities that lead to early retirement.

Overall, "night owls" were twice as likely as "early birds" to underperform at work, the new study found. Folks who stayed up late also ran a heightened risk...

A steady sleep routine may do more than keep you well-rested: New research suggests that the more swings in your slumber schedule, the worse your mood and depression symptoms are likely to be.

Researchers from Michigan Medicine followed the sleep patterns of interns in their first year of residency after medical school. That irregular sleep schedule can increase a person's risk of depress...

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...
