'Smart catheters' for the major problem of catheter-related infections (8/25/2012)

A new "smart catheter" that senses the start of an infection, and automatically releases an anti-bacterial substance, is being developed to combat the problem of catheter-related blood and urinary tract infections, scientists reported here today at the 244th National Meeting & Exposition of the American Chemical Society. ...> Full Article


Secrets of 'SuperAger' brains (8/24/2012)

Scientists for the first time have identified an elite group of elderly people age 80 and older whose memories are as sharp as people 20 to 30 years younger than them. And on 3-D MRI scans, the "SuperAgers"' brains appear as young -- and one brain region was even bigger -- than the brains of the middle-aged participants. The SuperAger's cortex was astoundingly vital and resembled the cortex of people ages 50 to 65. ...> Full Article


Scientists report promising new direction for cognitive rehabilitation in the elderly (8/23/2012)

Research has found that declines in temporal information processing, the rate at which auditory information is processed, underlies the progressive loss of function across multiple cognitive systems in the elderly, including new learning, memory, perception, attention, thinking, motor control, problem solving, and concept formation. In a new study, scientists have found that elderly subjects who underwent temporal training improved not only the rate at which they processed auditory information, but also in other cognitive areas. ...> Full Article


Red wine compound could help seniors walk away from mobility problems (8/21/2012)

In a stride toward better health in later life, scientists reported today that resveratrol, the so-called "miracle molecule" found in red wine, might help improve mobility and prevent life-threatening falls among older people. The finding, believed to be the first of its kind, was presented today to some 14,000 scientists and others gathered at the 244th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society. ...> Full Article


Why are elderly duped? Researchers explain why (8/18/2012)

Why are elderly duped? Researchers explain whyResearchers at the University of Iowa have pinpointed for the first time the area in the human brain where doubt arises. The finding helps explain why older people, as well as others with damage to a specific brain region, are more prone to fall victim to deception and scams. Results published in the journal Frontiers in Neuroscience. ...> Full Article


Researchers identify cellular basis for how anti-aging cosmetics work (8/16/2012)

A team of investigators from UC Davis and Peking University have discovered a mechanism that may explain how alpha hydroxyl acids (AHAs) -- the key ingredient in cosmetic chemical peels and wrinkle-reducing creams -- work to enhance skin appearance. An understanding of the underlying process may lead to better cosmetic formulations as well as have medical applications. ...> Full Article


Let's talk: The nature of the health care surrogate-clinician relationship (8/12/2012)

Let's talk: The nature of the health care surrogate-clinician relationshipA new study from the Regenstrief Institute and Indiana University School of Medicine examines the relationship between family members who make decisions for hospitalized older adults with impaired cognition and the doctors, nurses and other clinicians who care for these patients. ...> Full Article


Why do older adults display more positive emotion? It might have to do with what they’re looking at (8/11/2012)

Research has shown that older adults display more positive emotions and are quicker to regulate out of negative emotional states than younger adults. Given the declines in cognitive functioning and physical health that tend to come with age, we might expect that age would be associated with worse moods, not better ones. So what explains older adults' positive mood regulation? A new article in Current Directions in Psychological Science suggests one possible explanation: Positive looking. ...> Full Article


Memory improves for older adults using computerized brain fitness program (8/7/2012)

UCLA researchers found that older adults who regularly used a brain fitness program played on a computer demonstrated significantly improved memory and language skills. ...> Full Article


Alzheimer's cognitive decline slows in advanced age (8/6/2012)

The greatest risk factor for Alzheimer's disease (AD) is advancing age. By age 85, the likelihood of developing the dreaded neurological disorder is roughly 50 percent. But researchers at the University of California, San Diego School of Medicine say AD hits hardest among the "younger elderly" ? people in their 60s and 70s ? who show faster rates of brain tissue loss and cognitive decline than AD patients 80 years and older. ...> Full Article

Protein-based coating could help rehabilitate long-term brain function (8/2/2012)

Tel Aviv University has developed a bioactive coating which not only "camouflages" electrodes in the brain tissue but also suppresses the brain's immune response. With this method, researchers hope to turn the short-term effects of deep brain stimulation into a long-term solution. ...> Full Article


Concussions and head impacts may accelerate brain aging (8/1/2012)

Concussions and even lesser head impacts may speed up the brain's natural aging process by causing signaling pathways in the brain to break down more quickly than they would in someone who has never suffered a brain injury or concussion. ...> Full Article
