Big surges in new autism diagnoses among young adults, as well a rise in diagnoses for girls and young women, have driven a near-tripling of U.S. autism cases in just over a decade, researchers report.

Data on over 12 million patients enrolled in major U.S. health care systems found that between 2011 and 2022 the number of people diagnosed with autism climbed by 175%, according to a study...

Find it hard to take time to exercise during your busy workweek?

No problem, a new study says -- one or two “weekend warrior” workouts are just as likely to help you maintain your brain health.

People who regularly exercise, whether solely on the weekend or thro...

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...

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...

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

MS patients felt significantly less fatigue after they were prescribed modafinil (Provigil), a drug that promotes wakefulness and is used to treat sleepiness, researchers repor...

Certain gut microbes might be linked to a person’s risk of developing Parkinson’s disease, a new study suggests.

People prescribed multiple courses of penicillin antibiotics have a modestly lower risk of developing Parkinson’s, researchers found.

Those antibiotics ...

Add Alzheimer’s disease to the list of conditions that might benefit from the revolutionary diabetes drug Ozempic, a new study says.

People with type 2 diabetes taking semaglutide appeared to have a significantly lower risk of developing Alzheimer’s compared to patients taking seven other diabetes drugs, researchers reported...

Maybe you've seen a cartoon character shake their head back and forth following a sharp blow -- clearing away whatever stars or birds are circling their noggins.

Turns out, that same move might help coaches and physical trainers identify a concussi...

Alzheimer’s disease might damage the brain in two distinct phases, a new study suggests.

An early phase that occurs slowly and silently appears to lay the groundwork for a second, more widely destructive phase of Alzheimer’s, according to s...

A simple tweak in available vial sizes of the breakthrough Alzheimer’s drug Leqembi could save Medicare hundreds of millions of dollars each year, a new analysis claims.

About 6% of Leqembi (lecane...

Bilingual people have more active and flexible brains, a new study has discovered.

Brain scans revealed that folks who speak two languages have increased connectivity between their brain regions, researchers reported Oct. 10 in the journal Communications Biology.

This connectivity is strongest in people who le...

This year, breakdancing joined the ranks of Olympic-caliber sports, with Japan’s B-girl Ami Yuasa and Canada’s B-boy Phil Wizard taking home the gold.

Now doctors warn breakdancing shares something else with other major sports – the risk of serious overuse injury.

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

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...

Damage to the brainstem could be behind the physical and psychological effects of Long COVID, a new study suggests.

Brain scans of 30 Long COVID patients found they had damage to the region of the brainstem associated with breathlessness, fatigue and anxiety, researchers reported Oct. 7 in the journa...

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
