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 str...
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."
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...
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.
Blood vessel damage and inflammation in the brains of deceased COVID-19 patients suggest the damage is not caused by the virus, but the body's immune response to it.
Researchers from the U.S. National Institutes of Health (NIH) consistently found signs of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after getting COVID-19.
As COVID-19 continues to spread and people face more isolation than usual, researchers are noting the impact of loneliness on the brain.
A new study from McGill University in Montreal found a tell-tale signature in the brains of lonely people. Specifically, they discovered variations in the volume of different brain regions and how those regions communicate across brain networks.
Some older folks are still sharp as tacks and dementia-free well into their 80s and beyond. Now German researchers have uncovered a possible reason why: Their genes may help them fend off protein build-up in the brain.
The finding is based on a study of brain images of 94 participants, all aged 80 or older. They were characterized by the amount of tau protein tangles and beta-amyloid pro...
Researchers say a multiple sclerosis drug meant to slow physical disability also shows promise in improving mental acuity in people who are living with secondary progressive MS, an advanced form of the disease.
The new study found that people taking the drug, called siponimod, for one to two years showed improvements in "cognitive processing speed" compared to those who took a placebo.
There's growing evidence that children with dyslexia may have heightened social and emotional intelligence.
Along with showing that dyslexia may be much more complex than poor reading skills, new study findings add to previous research indicating that dyslexia is often linked with hidden interpersonal strengths.
"There are anecdotes that some kids with dyslexia have greater so...
Children with tough-to-treat epilepsy now have another choice to help them live a life free of seizures, a new study suggests.
MRI-guided laser interstitial thermal therapy, a minimally invasive procedure for kids who have drug-resistant epilepsy, is successful in more than half of all cases and has a short recovery time, researchers report.
Targeted microwaves were the likely cause of mysterious illnesses that afflicted staff and their families at U.S. embassies in Cuba and China, according to a U.S. National Academies of Sciences, Engineering, and Medicine report.
Symptoms included ear pain, intense head pressure or vibration, dizziness, visual problems, thinking difficulties and the perception of loud noise.
Special training may help COVID-19 patients regain their sense of smell after suffering parosmia, a new British study suggests.
Parosmia is a condition where people have strange and often unpleasant smell distortions. Instead of smelling a lemon, for example, you may smell rotting cabbage, or chocolate may smell like gasoline. Parosmia has been linked to COVID-19 and other viruses and hea...
Delirium is often the first symptom of COVID-19 to appear in older people, a new study finds.
They may have confusion with an altered level of consciousness, disorientation, inattention and other mental disturbances, but none of the other typical signs of the coronavirus infection, such as fever and cough, researchers say.
"COVID can operate through multiple ways to affect the ...
Older adults with memory problems may progress to Alzheimer's more quickly if they are also suffering from anxiety symptoms, a preliminary study suggests.
It's common for people with Alzheimer's disease to have mood symptoms, including anxiety and depression. And some research has suggested those symptoms can, in older people, act as early indicators of the dementia process.
Imagine standing at your bathroom sink, and then you suddenly find yourself in bed but you don't remember how you got there. Then you discover hours have passed, yet you have no memory of what happened during that time.
That frightening scenario happened to Amy Losak, 64, twice, once in October 2016, and then again in September 2020.
Losak, a health care public relations professiona...
Women who work outside the home may end up with a sharper memory later in life, a new study suggests.
Researchers found that among nearly 6,200 U.S. women aged 55 and older, those who'd worked for pay in young adulthood and middle-age were less prone to memory decline, versus those who'd stayed out of the labor force.
The link was seen whether women were married or single, or had ch...
Autism may involve nerves that control touch, pain and other sensations as well as the brain, a new study suggests.
"More than 70% of people with autism have differences in their sensory perception," said researcher Dr. Sung-Tsang Hsieh, an attending neurologist at National Taiwan University Hospital in Taipei. "For some people, even a light touch can feel unbearable while others...
Learning to play a musical instrument helps fine-tune kids' brains, researchers say.
In a new study, 40 children (aged 10 to 13) performed memory and attention tasks while their brain activity was monitored with functional MRI. This type of imaging scan detects small changes in blood flow within the brain.
Twenty of the children played an instrument, had completed at least t...
A common type 2 diabetes drug called metformin may have an unexpected, but positive, side effect: New research suggests that people taking the drug appear to have significantly slower declines in thinking and memory as they age.
"Our six-year study of older Australians with type 2 diabetes has uncovered a link between metformin use and slower cognitive [mental] decline and lower deme...
For the very young, sleep builds and strengthens the brain, but it quickly switches to maintenance and repair before a child turns 3, new research shows.
Before about the age of 2½, the brain grows rapidly. And during REM (rapid eye movement) sleep a baby's brain builds and strengthens synapses, which connect neurons to each other so they can communicate.
A group of widely used medications might speed up older adults' mental decline -- especially if they are at increased risk of dementia, a new study hints.
The medications in question are called anticholinergics, and they are used to treat a diverse range of conditions -- from allergies, motion sickness and overactive bladder to high blood pressure, depression and Parkinson's disease.<...
A new brain scan study shows why the "one day at a time" approach works for recovering alcoholics.
"For people with AUD [alcohol use disorder], the brain takes a long time to normalize, and each day is going to be a struggle," explained senior study author Rajita Sinha, a professor of psychiatry and neuroscience at Yale University's Child Study Center. "For these people, it really is ...
Most strokes strike when an artery in the brain suddenly becomes blocked, but new research shows a rarer cause of strokes is becoming more common.
It's called cerebral venous thrombosis (CVT), and it happens when a vein in the brain is clogged. While CVT is estimated to cause less than 1% of all strokes, scientists discovered it is now more prevalent and affecting a different demo...
Even if they appear unresponsive, dying people may still be able to hear.
That's the takeaway from a Canadian analysis of hospice patients in Vancouver.
Researchers compared electroencephalography (EEG) data -- a measure of electrical activity in the brain -- collected when patients were conscious and when they became unresponsive at the end of life. Those patients were comp...
People who eat healthfully may be less likely to develop a constellation of symptoms that can precede Parkinson's disease, a large new study suggests.
Researchers found that people who closely adhered to a Mediterranean-style diet were about one-third less likely to develop at least three "prodromal" features suggestive of Parkinson's disease, compared to those who stuck with meat and...
