A team from the University of California, Los Angeles and Harvard University pai...
Having higher blood sugar can lead to quicker loss of brain power after a stroke, a new study suggests.
High blood pressure and cholesterol were not associated with a similar mental loss, even in those at higher genetic risk for dementia.
“Having a stroke increases a person’s risk of dementia up to 50-fold, but we lack a comprehensive treatment approach that could reduce this ri...
Regular exercise has a long list of health benefits, and a new study suggests another one could be added: a lower risk of Parkinson's disease.
The study, of nearly 99,000 French women, found that those who were most physically active day to day were 25% less likely to develop Parkinson's ov...
When parents talk to their toddlers, they are not only teaching them words, but may be shaping their developing brains, too, a new study suggests.
Researchers found that toddlers whose parents spent a lot of time talking to them day to day showed a particular brain characteristic: a greater concentration of myelin in language-related parts of the brain.
Myelin is a protective layer ...
MONDAY, May 15, 2023 -- Researchers have discovered a genetic mutation that should actively protect people from Alzheimer's, thanks to a man belonging to a Colombian family known to be susceptible to the degenerative brain disease.
Based on his family's genetics, this unnamed patient should have started showing signs of Alzheimer's in his 40s.
“They start getting impaired at age 4...
Lightbulb inventor Thomas Edison believed a little shuteye could boost his creativity. Contemporary scientists think the iconic innovator was on to something.
But timing is key, they say.
“We found a strong effect of ‘sleep onset' on creativity,” said study author Kathleen Esfahany, an unde...
Poor sleep brought on by sleep apnea may ultimately undermine the brain health of older men and women, new research suggests.
The concern stems from a new brain scan investigation that involved 140 sleep apnea patients.
“Sleep apnea is a medical condition in which patients ... stop breathing during sleep, which can affect their sleep quality by causing multiple arousals and droppi...
Researchers have isolated for the first time a free-floating form of amyloid beta that appears to be a key driver of Alzheimer's disease.
Further, they argue that a newly approved Alzheimer's drug — lecanemab (Leqembi) — directly targets these small, complex chains of amyloid beta (A-beta) called fibrils. The U.S. Food and Drug Administration approved lecanemab in January.
The A...
For the first time, doctors have successfully performed fetal brain surgery to treat a rare blood vessel abnormality that can be fatal to newborns.
Experts said the accomplishment, for a condition known as a vein of Galen malformation (VOGM), is "exciting." But they also cautioned that this is one case, and more research is needed to know whether the prenatal brain procedure is a good str...
In trying to untangle the mysteries of long COVID, researchers have found anxiety and depression may play a role for some of those with the lingering condition.
In the study from researchers at University of California, Los Angeles (UCLA), patients who perceived that they had thinking difficulties during COVID infection were also more likely to have lingering physical symptoms than those...
Getting good sleep is an important part of wellness for many reasons, but new research suggests deep sleep may even guard against memory loss linked to Alzheimer's.
While disrupted sleep has been linked with accumulating beta-amyloid plaques in the brain faster, scientists found that superior amounts of deep, slow-wave sleep can be protective against memory decline in those with a high bu...
In U.S. states that provide financial assistance for low-income families, the difference is evident in children's brains, researchers report.
Their study found disparities in brain structure between children from high-income households compared to low-income households. However, the disparity was more than a third lower in states offering greater cash assistance to low-income families, c...
Near-death experiences — seeing a bright light, floating outside your body, watching your life flash past, communicating with lost loved ones — could well be part of a dying brain's final fight-or-flight response, a new report suggests.
Electroencephalogram (EEG) readings of dying intensive care unit patients found that some experienced a surge of brain activity in regions associated ...
A mind-reading device seems like science fiction, but researchers say they're firmly on the path to building one.

Scientists report that brain scans of long COVID patients show abnormal activity in areas related to memory.
The scan results validate the concerns of these patients, who feel like they're experiencing fatigue, trouble concentrating and memory issues, even though their scores on thinking tests don't show it.
“We were able to show that even though they were able to do the task -- t...
An extended-release version of a Parkinson's disease drug could provide more stable relief for patients with the movement disorder, new clinical trial data show.
The new formulation of levodopa, called IPX203, extended the duration of patients' “on time" — the amount of time the medication is working and symptoms are lessened, researchers reported this week at the American Academy of...
A significant number of patients take far longer to recover from a concussion than expected, and they may not be getting the care they need, according to a new study.
Researchers from the United Kingdom who studied concussion patients found that almost half had changes in how regions of the brain communicate with each other. This may cause long-term symptoms, including fatigue, and impair...
Maintaining tight control of your blood pressure could help your brain, potentially reducing your risk of stroke, a new study says.

This isn't to sa...
Comedian Richard Lewis is the latest celebrity to reveal that he has been diagnosed with the central nervous system disorder Parkinson's disease.
Lewis, 75, said in a
Reading is fundamental, but it's also a complex skill. Now, a new study sheds more light on how the brain makes sense of the written word.
Researchers found that two key brain "networks" work in tandem to help people read sentences -- so folks not only grasp the meanings of individual words but also process the bigger picture of what's being said.
Because reading is such an essentia...
Researchers studying how tiny plastic particles can breach the protective blood-brain barrier report they have found that answer, thanks to mice and computer modeling.
"With the help of computer models, we discovered that a certain surface structure [biomolecular
corona] was crucial in enabling plastic particles to pass into the brain," said study co-author
Growing numbers of people have MRI brain scans to find out what's causing their headaches, see if they have a concussion or for another reason, when a doctor may spot the tell-tale lesions of multiple sclerosis (MS).
Called radiologically isolated syndrome, this occurs in people who have no MS symptoms but whose scans show abnormalities that are similar to those seen with MS. For doctors,...
Scientists say their new study has overturned settled science, finding a new cause for a metabolic disease that causes neurological damage and sometimes death in Native American children.
The good news is that this may lead to better treatment for the condition.
While people with the inherited condition Glutaric Aciduria Type I (GA-1) had been believed to be affected by toxic subs...
For people with epilepsy, living in lower-income neighborhoods is associated with worse mental functioning, new research suggests.
For the study, the researchers looked at the memory, thinking ability and mental health of people with epilepsy, and found differences based on where they lived. Brain-health issues were more common among those from disadvantaged areas with fewer educational a...
While mild cases make up the majority of autism diagnoses, "profound" autism affects about 27% of American children with the developmental disability, the U.S. Centers for Disease Control and Prevention reported Wednesday.
This is the first time the CDC has broken down that definition statistically.
Children with profound autism are nonverbal, minimally verbal or have an IQ of ...
For people with the abnormal heartbeat atrial fibrillation, a procedure called catheter ablation may do more than return the heart to its normal rhythm. It may also ward off mental decline and dementia linked to A-fib, a new study says.
Researchers found that people who receive catheter ablation in addition to medical management for A-fib may be almost 40% less likely to develop cognitive...
A teenager's brain power appears to have little bearing on whether they will become overweight or obese as adults.
British researchers found that, on average, sharper teens weighed only slightly less in adulthood than siblings who scored lower on tests of thinking skills, according to a new study published April 13 in the journal PLOS Medicine.
The difference amounted to ju...
Sleep apnea is a very disruptive breathing disorder that's believed to rob millions of Americans of sound, restful sleep.
Now, a small, new study suggests the disorder may also prompt a decline in brain health among middle-aged men who have no other significant health issues.
That decline can manifest as significant memory loss, less impulse control, impaired spatial reasoning, and...
It's highly unlikely, but COVID-19 can be transmitted from mother to baby through the placenta, causing injury to the developing fetus' brain, a new study finds.
Researchers shared two unusual cases among hundreds of pregnant and delivering mothers they saw who were infected with COVID.
In both cases, the infants tested negative for COVID at birth, but had significantly elevated vi...
Sleep problems — from snoring to sleeping too much or too little — may be associated with elevated stroke risk, researchers say.
Snorting during sleep, having poor quality of sleep and sleep apnea may also be linked with greater risk of stroke, according to study findings published online April 5 in the journal Neurology.
“Not only do our results suggest that individu...
Your body's internal clock appears to play a big part in the time of day when severe headaches happen.
Migraines and cluster headaches have different characteristics and treatments, but experts have long noted that they share key features: Both are neurological diseases in their own right, rather than symptoms of another underlying condition. And because neither can be easily identified ...
It's long been thought that working out helps a person stay sharp, but a new review argues there's little solid scientific evidence for the mental benefits of physical exercise.
Individual clinical trial results have tended to support the idea that regular exercise helps maintain brain health.
But a combined review of 109 trials involving more than 11,000 healthy folks found evidenc...
Boys born to women who had COVID-19 during pregnancy may be at risk for developmental delays, a new study suggests.
Delays in speech and motor function were the most commonly diagnosed conditions in these children at 12 months. They were seen in boys but not in girls, the study authors said.

Teenagers with the nighttime breathing disorder sleep apnea may have brains that look a little different from their peers', a new study suggests.
Researchers found that among nearly 100 teens who underwent brain scans, those with obstructive sleep apnea (OSA) tended to have thinner tissue at the brain's surface, and some signs of inflammation in a brain area key to memory and learning.
A new study hones in on what part of your brain controls walking.
Researchers discovered that two main regions of the cortex were activated as people moved in various ways through an environment. But the occipital place area (OPA) didn't activate during crawling, while the second region, the retrosplenial complex (RSC), did.
RSC supports map-based navigation, according to the resear...
Exercise can help improve movement-related symptoms for people who have Parkinson's disease, a new review finds.
And any type of structured exercise is better than none, researchers added. The findings were published recently in the Cochrane Reviews.
Problems walking and talking or thinking at the same time might be a warning sign of impending dementia, a new study suggests.
Being unable to juggle two tasks simultaneously has been recognized as a sign of mental (or "cognitive") decline after age 65, but this research shows that the ability actually starts to fall off in middle-age. The finding could spur calls for earlier screening, r...
Do you ever wonder why you typically feel hungry when it's time for dinner?
Researchers say that's not just a habit, but a physiological drive, with the human body able to predict the timing of regular meals.
“We often get hungry around the same time every day, but the extent to which our biology can anticipate mealtimes is unknown. It is possible that metabolic rhythms align to m...
The list of symptoms that can strike long COVID sufferers has just gotten a little longer, and a little more mysterious: Researchers are reporting a case of "face blindness" related to the syndrome.
The condition, known medically as prosopagnosia, causes a very specific impairment: trouble discerning one face from another. Even the once-familiar face of a loved one might as well be a stra...
