Taking good care of your teeth -- brushing, flossing, regular dental checkups -- is, of course, important for good health. Now researchers say it's also vital for brain health.
While it was already clear that poor dental health could increase stroke and heart disease risk, a new study funds that adults who are genetically prone to have cavities, dentures and missing teeth are also more li...
American adults who have epilepsy and are Black or Hispanic are less likely than white adults to be prescribed the latest medications, according to new research.
“While finding the right medication is often a trial-and-error process that is based on the individual, studies have shown that use of newer medications improves outcomes, and some newer medications have fewer side effects,” ...
Six minutes of high-intensity exercise might prolong the lifespan of a healthy brain, perhaps delaying the start of Alzheimer's and Parkinson’s diseases, a new, small study suggests.
Researchers found that short but intense cycling increased the production of a protein called brain-derived neurotrophic factor (BDNF), which is essential for brain formation, learning and memory. It's tho...
Social media's impact on young people is a hot topic, with most kids and teens wanting to do whatever their friends are doing and parents worrying about setting limits.
A new study examines whether frequent checking of social media sites (Facebook, Instagram and Snapchat) is associated with changes in functional brain development in these early adolescents, about age 12.
Those seemingly random kicks or wiggles a newborn baby makes have a purpose.
With each movement, the baby is developing its sensorimotor system, which it will later use to perform sequential movements. The sensorimotor system lets a person control muscles, movement and coordination.
Researchers studying these “spontaneous” newborn movements and comparing them to babies a few mon...
One of the hallmarks of a COVID-19 infection has been a lost sense of smell after the infection ends.
In a new study, researchers blame an ongoing immune assault on the olfactory nerve cells — cells found at the top of the nasal cavity — and a decline in the number of those cells. The study was led by a team at Duke Health in Durham, N.C.
Researchers are studying whether deep brain stimulation could help people with Alzheimer's hold on to their memory longer, and now a new finding may help refine the approach.
Deep brain stimulation (DBS) is an established treatment for several medical conditions, including epilepsy, Parkinson's disease and obsessive-compulsive disorder. It involves implanting electrodes in certain areas o...
Having short, painful headaches for many days or even weeks in a row may signal that you're more likely to have other medical woes, researchers say.
These "cluster headaches" are extremely painful and can last from 15 minutes to three hours at a time. And people who have them may be more than three times more likely to have other medical conditions, such as heart disease or mental disorde...
Stiff-person syndrome: Superstar singer Celine Dion announced Thursday that she is living with this rare neurological condition and has canceled and postponed tour dates to deal with her health issues.
"Recently, I've been diagnosed with a very rare neurological disorder called the stiff-person syndrome, which affects something like one in a million people," Dion, 54, said on
Chips, pizza, cookies: Delicious, but a diet full of ultra-processed foods like these may contribute to brain deterioration, researchers report.
Ultra-processed foods have lots of added and unhealthy ingredients, such as sugar, salt, fat, artificial colors and preservatives. Examples include frozen meals, soft drinks, hot dogs and cold cuts, fast food, packaged cookies, cakes and sal...
Two people have now died from brain hemorrhages that may be linked to an experimental Alzheimer's drug, calling into question the medication's safety.
A 65-year-old woman with early-stage Alzheimer's recently died from a massive brain bleed that some researchers link to lecanemab, an antibody drug designed to bind to and remove amyloid-beta from the brain, according to a report published ...
Kids who are overweight or obese often struggle with school work, and now new research provides clues on how excess weight may harm the developing brain.
“The main takeaway is to raise awareness about brain health consequences of obesity besides physical health consequences, especially since obesity rates are very high and continue to rise,” said study author
Eating more berries and drinking tea may help slow mental decline as you age, new research suggests.
In a study of more than 900 adults, researchers found that foods like these -- containing antioxidant flavonols -- delivered brain benefits to older adults. Flavonols are found in fruits like berries, green leafy vegetables, tea and wine.
A common characteristic of autism is a reluctance to make eye contact with others, and researchers now think they know where in the brain this comes from.
Brain scans show that folks with autism spectrum disorder (ASD) had significantly less activity in their dorsal parietal cortex during eye-to-eye contact, compared to people without ASD, researchers report.
People have long talked about having near-death experiences in which they felt they were looking down on themselves while others tried to save them.
Now researchers have documented some of those experiences. In a new study, investigators found that about 20% of patients recalled lucid experiences of death that occurred while they were seemingly unconscious and dying.
It's time for time to fall back an hour, but fortunately that change is more in line with humans' circadian rhythm than springing forward.
This provides an opportunity for people to “fix” their circadian rhythm, that 24-hour body clock that regulates hormone release and temperature, said an expert from Baylor College of Medicine who offered some tips.
Older adults looking to slow down memory loss might find some help in a classic brain-teaser: the crossword puzzle.
That's the suggestion of a small study that followed older adults with mild cognitive impairment — problems with memory and thinking that may progress to dementia over time. Researchers found that those randomly assigned to do crossword puzzles for 18 months showed a small...
