There May Be a Better Way to Treat Hematoma Brain Bleeds

After a hit to the head or a fall, people, especially seniors, can develop a dangerous pooling of blood and fluid between the brain's surface and it's protective covering, the dura.

These "subdural hematomas" typically require surgery to fix, but a new study suggests a better approach, one that makes sure repeat surgeries aren't required.

That's important, because “even after...

Living in Space Won't Permanently Harm Astronauts' Thinking Skills

For astronauts who spend months at a time working on the International Space Station (ISS), there's good news.

While their bodies and brains are affected by radiation, altered gravity, challenging working situations and sleep loss on these missions, a study of 25 astronauts found no evidence that those conditions damage their thinking skills over the long haul.

"Living and working i...

What’s more, the earlier preterm a baby is born, the worse his or her future prospects a...

Scientists Track Brain Function as Folks Watch Movies

A person’s brain performs an intricate juggling act while watching a movie, a new study demonstrates.

Scans showed that 24 different brain networks and regions engage from scene-to-scene, based on hard it is to follow the movie or what’s currently on the screen, researchers reported.

The brain’s “executive control” networks -- regions related to plannin...

Too Many Meds: 'Polypharmacy' Can Really Harm Alzheimer's Patients

Alzheimer’s disease patients prescribed fistfuls of daily drugs are at greater risk of harm, a new study warns.

Patients with Alzheimer’s prescribed five or more daily medications suffer from more symptoms, falls and hospitalizations, and t...

No Evidence Adults With Autism Are More Vulnerable to Criminals, Study Finds

Are people with autism less able to "read" the nefarious intent of criminals, leaving them more vulnerable to scams or coercion into criminal activity?

It's been a common notion among trial lawyers, the Australian researchers behind a new report say, but it's not grounded in any real evidence.

"This perspective may not hold up under scrutiny and we found that, in general, autistic a...

Costs for MS, Parkinson's and Alzheimer's Meds Keep Rising

A person battling multiple sclerosis spent an average of $750 in out-of-pocket fees on medicines in 2012, but by 2021 that same patient spent $2,378 annually, a new report finds.

    Can Cannabis Change Your Brain? Maybe, Maybe Not

    People who regularly use marijuana experience changes in their brain structure and function, but it’s not clear that cannabis is the cause, a new study finds.

    Researchers found specific differences in the brains of people who’d ever used weed, particularly in areas densely packed with cannabinoid receptors. However, genetic analysis couldn’t pin down any specific associa...

    People's Brains Now Process Texts Almost as Quickly as Pictures

    Texts deliver rapid-fire messages, but a new study indicates human brains can keep up with the barrage.

    The brain can detect the basic linguistic structure of a brief sentence in roughly 150 milliseconds -- about the speed of a blink of an eye, researchers report.

    “Our experiments reveal that the brain’s language comprehension system may be able to perceive language simi...

    What Works Best to Ease MS-Linked Fatigue? New Study Finds Out

    Medication and behavioral therapy are both effective in combatting fatigue caused by multiple sclerosis (MS), either separately or together, a new study finds.

    Specifically, breakers appear to run the risk of “headspin hole” or “breakdance bulg...

    Injected 'Nanodiscs' Could Bring Brain Stimulation Therapy Without Implants

    Microscopic magnetic nanodiscs could provide a much less invasive means of providing deep brain stimulation, a new study says.

    The tiny discs – about 250 nanometers across, or 1/500 the width of a human hair – would be injected directly into specific regions of a person’s brain, researchers say.

    From there, researchers said, the discs could be activated by applying...

    Could Lithium Supplements Ease the Brain Fog of Long COVID?

    A small dose of the nutritional supplement lithium asparate may not ease the fatigue and brain fog of Long COVID, a small, new trial involving 52 patients has found.

    Still, it's possible that a larger dose of the mood-enhancing supplement might work, researchers said.

    Importantly, the supplement contains much

    Some Diabetes Meds Could Lower Odds for Dementia, Parkinson's

    A specific class of diabetes drug appears to lower people’s risk for dementia and Parkinson’s disease, a new study shows.

    Sodium-glucose cotransporter-2 (SGLT2) inhibitors, also known as gliflozins, lower blood sugar by prompting the kidneys to filter sugar out of the bloodstream and excrete it in urine, researchers said.

    But these drugs might also protect brain health, ...

    Breathing Could Bring Microplastics Into the Human Brain, Study Shows

    For the first time, scientists have detected microscopic microplastics lodged in the human brain.

    Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected within their brain's smell centers, the olfactory bulb.

    The particles were likely breathed in over a lifetime, since tiny floating microplastics are ubiquitous in the air.

    Study Debunks Theory Linking Autism to Changes in Brain's Amygdala

    A new brain imaging study has concluded that autism likely isn’t caused by faulty connections to the amygdala.

    A prevailing hypothesis of autism spectrum disorder has held that people with the condition have poorer neural connections in certain brain regions, including the amygdala.

    However, researchers found no evidence that people with autism had amygdala connections that di...

    Depression Might Sometimes Be Early Sign of Alzheimer's Disease

    In some people, new-onset depression may stem from the same buildup of toxic plaques in the brain that have long been linked to Alzheimer's disease, according to a new study.
