'Rogue' Protein Spread Key to Alzheimer's

Discovery casts light on tangles found in brains of disease sufferers

(Newser) - A protein linked to Alzheimer’s can run amok in the brain, affecting healthy tissue, scientists have found. All nerve cells contain the tau protein, but a “rogue form” can lead to protein clumps in cells, called neurofibrillary tangles, that are believed to play a major role in Alzheimer’... More »

'Walk and Die' Syndrome Likely Killed Richardson

Head injury from ski fall caused delayed bleeding in the brain

(Newser) - The head injury Natasha Richardson sustained in a skiing accident produced what doctors call "walk and die" syndrome, a UCLA neurologist tells the Los Angeles Times.

Left-Handed Men Earn More: Study

Southpaws struggle in school but surpass righties at work

(Newser) - Left-handed men earn an average of 5% more than right-handed men, two British and Irish studies have discovered. The studies found that southpaw males tended to do worse in school—possibly because of trouble adapting to a right-handed world—but were more successful as adults. Female lefties, however, did worse... More »

Scientists Wipe Mouse Memories

Treatment selectively erased memories of electric shocks

(Newser) - Scientists have succeeded in blanking selected memories from the brains of mice, Reuters reports. After brain protein levels were manipulated, the mice lost the memory of an electric shock but didn't forget anything else. The researchers said it was doubtful that it would be possible—or desirable—to do the... More »

Brain Pacemakers May Revolutionize Treatment

(Newser) - The precise application of electricity to certain areas of the brain—the same principles a pacemaker uses for the heart—is showing promise for people with an array of illnesses such as Parkinson's, severe depression, epilepsy, and Alzheimer's, the Chicago Tribune reports. The treatment, called deep brain stimulation, remains in... More »

Archery's Terrifying Secret

Experts can't even say the name of biggest fear: target panic

(Newser) - The greatest fear of elite archers is something called "target panic"—an affliction that keeps some from releasing their bow, and causes others to shoot wildly as soon as the bull's-eye comes into sight. Many archers won't even say the words, although the condition has at some time... More »

'Pre-Dementia' on the Rise

Mild impairment strikes nearly a million elderly a year, especially men

(Newser) - Almost a million Americans each year develop a mild form of memory loss that is often a precursor to Alzheimer's, according to new research. Mild Cognitive Impairment—more serious than normal "senior moments"—was found to be more common in men, the Los Angeles Times reports. Doctors warn... More »

Hands-Free Phones Still Dangerous Driver Overload

Scientists say any kind of phone use makes for risky driving

(Newser) - California motorists are now banned from using cell phones, but scientists say the move won't make the freeways any safer, reports the Los Angeles Times. Research shows that it is the lack of attention rather than occupied hands that impacts safety, and that drivers chatting on phones with both hands... More »

Depression Linked to Alzheimer's

Those prone to the blues may also be prone to dementia

(Newser) - Nearly 50% of Alzheimer's patients also suffer from depression, and new studies suggest the depression came first, WebMD reports. Researchers found that elderly people with a history of depression were much more likely to develop dementia. The findings give greater urgency to early treatment for depression, experts warn.

Study Links Sex and Gambling

Financial risk-taking lights up brain's pleasure center

(Newser) - Taking risks with money lights up the same parts of the brain as sexual arousal, a "neuroeconomics" study has found. Men shown sexy pictures gambled more daringly than those shown scary pictures—spiders and snakes—or neutral pictures, reports the AP. The study of 15 heterosexual Stanford students focused... More »

Heal Me, Amadeus!

Docs credit "Mozart effect" with improving epilepsy

(Newser) - A British patient's epilepsy showed remarkable improvement after he started listening to 45 minutes of Mozart daily, the Independent reports.

Why Girls Are Better at Language

Study finds brain wiring gives girls the edge

(Newser) - Study after study has found that girls have better language skills than boys, and scientists now think they've found a biological reason why, Scientific American reports.

Mind-Reading Edges Closer to Reality

New computer can determine what you're looking at

(Newser) - Mind-reading has taken a step toward possibility with a new computer that can decode brain activity to determine what a person is looking at with up to 90% accuracy, the Independent reports.

Chronic Pain Rewires the Brain

Researchers find suffering constant pain can cause permanent changes

(Newser) - Researchers studying the brains of people suffering from chronic pain have found that  an area of their cortex is permanently active when it should sometimes deactivate, Reuters reports.

Scientists Find Eternal Sunshine Spot in Your Mind

Study: Brain section thinks happy thoughts

(Newser) - If you think the glass is half empty, you’re a pessimist—but if you think it’s half full, you have strong activity in your rostral anterior cingulate cortex. That’s the section of the brain, located right behind the eyes, that controls optimism, according to a new study... More »

Education Staves Off Alzheimer's

But seems to speed progress of disease once it sets in

(Newser) - Higher levels of education help delay the onset of Alzheimer's, but once the disease takes hold, mental decline is faster among those with more schooling, researchers have found. Each year of  education is linked to a 2.5 month delay in accelerated memory loss, according to the study in Neurology.... More »
