Patients in the earliest stages of multiple sclerosis might develop certain symptoms that offer an early clue to the degenerative nerve disease, researchers report.
Depression, constipation, urinary tract infections and sexual problems are all more likely in MS patients five years before their official diagnosis, compared with people who never develop MS, researchers found.
Those c...
New research challenges a long-held notion that human newborns enter the world with brains that are significantly less developed than those of other primates.
Babies are born extremely helpless and with poor muscle control, and human brains grow much larger and more complex than other species following birth, investigators said.
Because of those observations, it’s long been b...
People with epilepsy suffer quicker declines in thinking than people without the brain disorder, particularly if they also have risk factors like high blood pressure or diabetes, a new study finds.
The difference was significant: Over the course of the 14-year study, those with epilepsy experienced a 65% to 70% faster decline in memory and thinking skills.
On top of that, having ris...
Gina Arata had a bright future, wrapping up college and preparing for law school, when a 2001 car wreck left her with lasting brain damage.
After her recovery, Arata wound up taking a job sorting mail, but struggled even in that.
“I couldn’t remember anything,” said Arata, who lives in Modesto with her parents. “My left foot dropped, so I’d trip over things all the time. I...
Doing some squats during commercial breaks or between YouTube videos can help couch potatoes keep their minds sharp, a new study suggests.

TUESDAY, Nov. 21, 2023 (HealthDay News) — A year after suffering a concussion, teens, especially boys, are more likely than their peers to think about, plan and even attempt suicide, new research finds.
With more concussions, the risk grows.
Teen boys who reported two or more concussions in the past year were two times more likely to report a suicide attempt than those who h...
Shrinkage of one of the brain's key memory centers appears to herald thinking declines, a new study finds.
The region in question is the hippocampus, a two-sided structure located roughly above each ear and embedded deep within the brain's temporal lobe. It's long been known to play a crucial role in the storage and transference of short- and long-term memory.
The new research was ...
An experimental device that isolates blood flow to the brain has the potential to revolutionize brain research.
The device redirects the brain’s blood supply through a pump that maintains or adjusts a range of variables necessary to maintain the organ, including blood pressure, temperature, oxygenation and nutrients, researchers report.
When tested on a pig brain, the device maint...
A seizure doesn’t always look like what you see in the movies, but a new survey finds most Americans don't know what the more subtle signs of seizures are.
“Anything that interrupts your brain’s circuit can cause seizures, from tumors, infections and strokes to high or low blood sugar, or glucose levels, to inherited genetic features. And different types of seizures can present with...
The ancient art of tai chi, plus a modern twist, may help older adults reverse mild declines in brain power, a new clinical trial reveals.
Researchers found that tai chi classes helped older adults improve their subtle problems with cognition (memory and thinking skills). It also helped them with a fundamental multitasking skill: walking while your attention is elsewhere.
But ...
You might be talking to a real person while on Zoom, but it's just not the same to your brain as a face-to-face conversation.
New research using sophisticated imaging tools found that the brain activity of people engaged in conversation looks dif...
Millions of older Americans may be unaware they have memory and thinking impairments -- mostly because their doctors aren't diagnosing them, new research suggests.
After analyzing Medicare data covering 40 million older Americans, researchers found that only a small percentage of expected cases of mild cognitive impairment (MCI) were actually diagnosed. The upshot was that more t...
A variety of risks can make it more likely that someone develops Alzheimer's disease or other dementias.
Now you can add neighborhood environment to that list. A new study finds low income levels and a lack of green spaces are among the factors that can harm brain health.

Alzheimer's robs its victims of their memories and there is no cure, but there are things you can do to prevent Alzheimer's disease.
With Alzheimer's, two types of brain proteins, called tau tangles and beta-amyloid plaques, grow out of control. According to Harvard Health, these proteins destroy brain cells and cause
Astronauts spending six months or longer in space should stretch their time between trips to three years, warns new research on the impact of space travel on the brain.
To study this, researchers examined the brain scans of 30 astronauts, looking at scans that depicted their brains both before and after their missions.
The research team included missions that were two weeks long, si...

Each year, about 140 kids in the United States are diagnosed with a craniopharyngioma, a typically non-cancerous brain tumor that develops near the pituitary gland at the base of the brain.
Doctors treat craniopharyngiomas with surgery to remove the entire tumor or a less aggressive surgery followed by radiation to kill any remaining cells.
Now, 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...

Black patients with brain tumors may be less likely to have surgery recommended to them than white patients are, according to a large U.S. study.
The research, which looked at two national databases, found that on average, Black patients were less likely to have surgery recommended for any of four types of brain tumor. That included three considered benign (non-cancerous) and one that is ...
Older adults who harbor more vitamin D in their brains may stay mentally sharper, a new study suggests.
Researchers found that when older adults had higher levels of vitamin D in their brain tissue, they tended to perform better on standard tests of memory and thinking. They were also less likely to have dementia or milder cognitive impairments.
Experts stressed that
Researchers have found a way to safely deliver a steady supply of chemotherapy directly to brain tumors -- in what they hope will be an important advance for patients with currently incurable cancers.
The treatment involves an implantable pump system that supplies a steady drip of chemo straight to the brain tumor. Researchers have tested it in five patients who had recurrent glioblastoma...
Regular aerobic exercise improves blood flow to the brain, which should help keep seniors sharper as they age, a new trial has revealed.
At least a half-hour of power walking or jogging four to five times a week promoted better blood flow in and out of the brain among a small group of older adults, said study co-author

Professional fighters take a lot of knocks to the head, but a new study suggests they may find themselves thinking more clearly again after they retire.
Many studies have pointed to the perils of repeated blows to the head in sports like boxing and football.
Though the risk appears small, a new review suggests that, in rare instances, monkeypox may trigger serious neurological complications, including seizures and brain inflammation.
The finding is based on a look at 19 studies conducted in the United States, the United Kingdom and across Africa.
