The discovery of a gene variant that rids the brain of toxic plaques linked to Alzheimer's might lead to new treatments for the disease, researchers report.

The variant arises naturally in people who don't seem to get Alzheimer's disease despite having another gene, called APOEe4, that strongly prom...

Desks that require folks to stand or move as they work also might help them produce better results on the job, a new study suggests.

People's brains became sharper when working at a desk that made them stand, step or walk rather than sit, results show.

Reasoning scores in particular improved when at an active workstation, researchers said.

“It is feasible to blend movement w...

As their aging brains shrink, older dogs can suffer the same memory and thinking problems as many older humans do.

But dogs are just like humans in another way -- playtime and social activities can help preserve their brain function, a new study finds.

Exercising, socializing, playing with toys and playing with other dogs helped a small group of beagles maintain their brains, resear...

For folks who have battled alcohol dependency for years, any treatment that could curb or block alcohol cravings would be a huge advance.

Now, research in mice is giving a glimmer of hope that just such a therapy might be possible.

A compound -- so far dubbed LY2444296 -- appears to block a key brain cell receptor called the kappa opioid receptor (KOP), a team at the Scripps Researc...

Out of a host of possible risk factors for dementia, three really stood out in a new analysis: Diabetes, air pollution and alcohol.

British and American researchers used brain scans to focus on a neurological network they labeled a "weak spot" in the brain. This network is known to be vulnerable to the effects of aging, as well as

  • In a new study, yoga appears to have bolstered the brain health of older women who had risk factors for Alzheimer's disease.

    The study can't prove that the ancient practice will slow or prevent the onset of Alzheimer's, but it did seem to reverse some forms of neurological decline, researchers said.

    “That is what yoga is good for -- to reduce stress, to improve brain health, subje...

    Pesticides and herbicides used in farming appear to increase people's risk of Parkinson's disease, a new, preliminary study finds.

    People exposed to pesticides and herbicides are 25% to 36% more likely to develop Parkinson's, according to a study to be presented at the American Academy of Neurology's upcoming annual meeting in April.

    The Parkinson's risk was specifically higher in t...

    Preventing noise-related hearing loss from a loud concert, a banging jackhammer or a rifle blast could be as simple as managing levels of zinc within the inner ear, a new study reports.

    Such hearing loss stems from cellular damage associated with an excess of free-floating zinc in the inner ear, researchers say.

    Lab mouse experiments showed drugs that soak up the excess zinc can hel...

    Could drugs that give a boost to men's sexual performance help them stave off Alzheimer's disease?

    That's the main finding from a study suggesting that erectile dysfunction meds like Cialis, Levitra and Viagra might lower the odds for the memory-robbing illness.

    The study wasn't designed to prove cause-and-effect, cautioned British researchers at University College London.

    No one's brain is as sharp at 60 as it was at 20.

    However, new research supports the notion that folk's brains can make subtle adjustments with age to compensate for that decline.

    A team of British researchers has found more evidence that as the mind ages, it sometimes recruits help from certain brain regions to make up for deficits elsewhere.

    This does not happen for everyone...

    Scientists say they've created the first 3D-printed brain tissue where neurons network and "talk" to each other.

    The breakthrough could be an advance for studying neurological processes in the lab, say a team from the University of Wisconsin-Madison.

    “This could be a hugely powerful model to help us understand how brain cells and parts of the brain communicate in humans,” said s...

    New research suggests healthy lifestyles can help stave off dementia, perhaps by building a resilient 'cognitive reserve' in the aging brain.

    The study was based on the brain autopsies on 586 people who lived to an average of almost 91. Researchers compared each person's lifestyle and end-of-life mental skills to their neurological signs of dementia, such as brain protein plaques or chang...

    'Young folk don't write in cursive anymore' is a common complaint of older folks in this keyboard-obsessed age.

    Now, new research suggests that kids who ignore handwriting are, in fact, missing out: By the time they reach college, their brain "connectivity" may be weaker than folks who write regularly.

    In a study of 36 university students, "we show that when writing by hand, brain c...

    Strange visual disturbances occur early in about 10% of Alzheimer's cases, and when this happens it almost always signals the impending arrival of the disease, a new study finds.

    The condition is called posterior cortical atrophy (PCA). It involves a sudden difficulty in performing vision-related tasks -- for example writing, judging whether an object is moving or stationary, or easily pi...

    There's information emerging on how the common Epstein-Barr virus (EBV) might be crucial to triggering multiple sclerosis (MS).

    The virus, which also causes "mono" (mononucleosis) and other illnesses, has gained prominence in recent years as a potential cause of MS. Over 95% of people are thought to carry EBV, although for most people it remains dormant.

    Now, a team of Texan researc...

    Exposing babies and toddlers to TV and other digital media could be linked to a heightened risk for dysfunction in what's known as "sensory processing," a new study warns.

    For example, kids might try to avoid the feel of certain clothing, the taste of ...

    How much a person believes in the strength of a drug might influence how powerfully that drug influences brain activity, a new study has found.
