Giving fewer needle sticks to premature newborns in the intensive care unit may improve growth of a key brain area, a new study suggests.

The thalamus relays sensory data from the body to the rest of the brain, where it registers as pain, touch or temperature.

For the study, researchers compared 86 premature infants who had a catheter placed in their central veins and cen...

One thing most people can agree on, even in these divided times, is the importance of voting. And 19-year-old Aboubakar Konate from New York City is no exception.

Despite a brain hemorrhage that left him partially paralyzed in March 2018, Konate plans to make his voice heard this November by casting his very first vote.

"Even when I was a little kid, I would think, 'I have...

Older adults who get together with friends, volunteer or go to classes have healthier brains, which could help them ward off dementia, according to a new study.

Researchers who used brain imaging to examine brain areas involved in mental decline found that greater social engagement made a difference in brain health.

Being socially engaged -- even moderately -- with at least one ...

An experimental drug combination lengthens survival for patients with amyotrophic lateral sclerosis (ALS), new research shows.

A previous clinical trial found that the two-drug combo -- called AMX0035 -- slowed progression of the neurodegenerative disease over six months.

The new clinical trial of 137 patients with the disease, also known as Lou Gehrig's disease, found that ...

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...

As President Donald Trump battles the coronavirus, researchers reveal concerning new findings: Neurological symptoms occur in 8 of 10 hospitalized COVID-19 patients.

These symptoms include muscle pain, headaches, dizziness, encephalopathy and "brain fog."

"Encephalopathy, which is characterized by altered mental function ranging from mild confusion to coma, is the most sever...

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.

After that, sl...

Everyone needs sleep, but too little or too much of it might contribute to declines in thinking, a new study suggests.

Too little sleep was defined as four or fewer hours a night, while too much was deemed 10 or more hours a night. The ideal amount? Seven hours a night.

"Cognitive function should be monitored in individuals with insufficient or excessive sleep," said study ...

A few minutes of moderate- to high-intensity aerobic activity -- like running or biking -- can boost young adults' memory and concentration for up to two hours, a new research review shows.

That's the takeaway from 13 studies published between 2009 and 2019. All looked at the short-term impact of bicycling, walking and/or running on the mental health of 18- to 35-year-olds.

...

Post-traumatic stress disorder (PTSD)may significantly increase the risk of dementia later in life, according to a new study.

The researchers found that people with a history of PTSD were up to two times more likely to develop dementia than those who never had PTSD.

"Our study provides important new evidence of how traumatic experiences can impact brain health, and how the l...

Smokers have a significantly raised risk of dying from a bleeding stroke, a new study warns.

For the study, researchers analyzed data from over 16,000 same-sex twin pairs in Finland. The twins were born before 1958 and followed for about 42 years (between 1976 and 2018).

During the follow-up, there were 120 deaths from subarachnoid hemorrhage (SAH). This is a type of bleedin...

A genetic variant in some people may be associated with mental decline that can't be explained by deposits of two proteins linked with Alzheimer's disease, researchers say.

They said their findings could lead to new treatments for Alzheimer's.

The two proteins are amyloid β and tau. Amyloid forms into plaques and tau forms into tangles. Both are found in the brains of A...

Adults process language on one side of the brain, but kids use both hemispheres, a new study suggests.

The finding might explain why children recover more easily from brain injuries than adults, the study authors added.

"This is very good news for young children who experience a neural injury," said researcher Elissa Newport. She's a neurology professor at Georgetown Univer...

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 ...

On the final night of the 2020 Democratic National Convention, the world heard from an improbable source -- a 13-year-old named Brayden Harrington.

Brayden was invited to speak because he has a frustrating and misunderstood condition that millions of Americans share, including Democratic presidential hopeful Joe Biden.

"We stutter," he explained in a video recorded for the...

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...

It may be possible to protect Parkinson's patients' brains from further damage by turning off a "master regulator" gene, researchers report.

"One of the biggest challenges in treating Parkinson's, other than the lack of therapies that impede disease progression, is that the disease has already laid waste to significant portions of the brain by the time it is diagnosed," said researche...

Feeling woozy when you stand up may be a sign of an increased risk of developing dementia, a new study suggests.

Doctors call this feeling "orthostatic hypotension," and it occurs when there's a sudden drop in blood pressure as you stand, explained a team of researchers from the University of California, San Francisco (UCSF).

The researchers found a connection between orth...

Obesity during pregnancy may hinder fetal brain development, a new study suggests.

Development of brain areas involved in decision-making and behavior may be affected as early as the second trimester, New York University researchers said.

"Our findings affirm that...

A new study confirms what your parents always told you: Getting an education opens the door to career opportunities and higher salaries. But it may also benefit your well-being in old age.

"The total amount of formal education that people receive is related to their average levels of cognitive [mental] functioning throughout adulthood," said researcher Elliot Tucker-Drob, from the Un...

Aging baby boomers may not be as mentally sharp as their parents were, a new study suggests -- raising questions about what the pattern could mean for future dementia rates.

Looking at two decades' worth of data on U.S. adults, the study found generational differences in tests of cognitive function. That refers to essential mental abilities such as remembering, reasoning and problem-s...

A new injection drug can prevent multiple sclerosis flare-ups better than an existing medication, a clinical trial has found.

The drug, called ofatumumab, beat a standard MS medication in reducing patients' symptom relapses. It also slowed down the progression of their disability over six months.

The researchers said the findings, published Aug. 6 in the New England Journ...

Among people who have the gene that carries a heightened risk for early-onset Alzheimer's disease, a new study suggests that more education might slow the development of beta-amyloid plaques in the brain.

About 1% to 6% of people with Alzheimer's disease have genes that put them at risk for early development of the disease, which can start in their 30s to 50s, the researcher...

Need fresh motivation to lose some weight? New research suggests that young adults who are overweight or obese face a higher risk for dementia in their golden years.

For the study, the researchers looked at just over 5,100 older adults who were involved in two long-term studies. The investigators found that women who were overweight between 20 and 49 years of age had nearly twice the ...

All the parents who force their children to play an instrument because it has been touted as a way to boost overall intelligence, take note.

The need is urgent: Alzheimer's is the most common fo...

Regular eye checks are crucial for people with early-stage glaucoma, a new study shows.

Glaucoma is a condition in which the optic nerve that connects the eye to the brain becomes damaged. It develops slowly and affects peripheral vision first. Untreated glaucoma leads to permanent vision loss.

Glaucoma makes it harder to see contrast -- the differences between shades of lig...

Dirty air is the curse of urban living, and studies have shown that breathing it in harms the brains of men and women alike.

But a new study suggests that diet can help reverse the damage: Older women who regularly ate fish rich in omega-3 fatty acids seemed to better withstand the neurological effects of smog.

"Omega-3 fatty acids have been shown to fight inflammation and m...

The older people get, the less likely they are to share memories, researchers say.

And when they do reminisce, older folks don't offer as much detail as younger adults do, new study findings show.

Over four days, University of Arizona researchers used a smartphone app to record random bits of conversations as 102 mentally healthy 65- to 90-year-olds went about their daily li...

Intense breathing problems may be the most widely reported feature of COVID-19, but new research warns that coronavirus can also take aim at the brain.

Infection can trigger serious nerve damage, stroke, inflammation and even wild bouts of delirium.

In fact, a bizarre array of delusions plagued nearly a quarter of the 43 British COVID patients whose cases are detailed in a n...

A simple blood test may predict the severity of a concussion as accurately as an invasive spinal tap, researchers report.

They focused on a biomarker called neurofilament light chain. This nerve protein can be detected in the blood and cerebrospinal fluid when nerve cells are injured or die, according to the study.

"When your brain is injured, neurofilament light chain leve...

It's a virus some might not even remember, but babies born to mothers infected with Zika who appeared normal at birth still experienced neurological or developmental problems, new research suggests.

A hallmark of infection with the mosquito-borne Zika virus in pregnant women is delivering a baby with an abnormally small head -- a condition called microcephaly. But as children exposed ...

Data from a five-year clinical trial is adding to growing evidence that deep brain stimulation (DBS) can slow the ravages of Parkinson's disease.

Researchers at Vanderbilt University Medical Center in Nashville, Tenn., said that the therapy appears to curb any worsening of tremor and other symptoms, as well as lessening a patient's need for medications.

"Parkinson's is relen...

The progression of Alzheimer's disease may accelerate as iron deposits build up in the brain, a new study finds, hinting at a possible role for the mineral in mental decline.

Using MRI scans of 200 older adults with and without Alzheimer's, researchers found that those with the disease generally had higher iron levels in various parts of the brain. And 17 months later, Alzheimer's pat...

Love a glass of wine with dinner? There's good news for you from a study that finds "moderate" alcohol consumption -- a glass or two per day -- might actually preserve your memory and thinking skills.

This held true for both men and women, the researchers said.

There was one caveat, however: The study of nearly 20,000 Americans tracked for an average of nine years found tha...

Women have more Alzheimer's disease-related changes in the brain than men, and this may be linked to hormonal disruptions at menopause, researchers say.

"About two-thirds of people living with Alzheimer's are women, and the general thinking has been it's because women tend to live longer," said study author Lisa Mosconi of Weill Cornell Medicine in New York City.

"Our findin...

Patients with severe COVID-19 may be at risk for a variety of brain complications -- from stroke to psychosis, new research suggests.
