New clues as to why some older people may be losing their memory (12/31/2011)

New research links 'silent strokes,' or small spots of dead brain cells, found in about one out of four older adults to memory loss in the elderly. The study is published in the Jan. 3, 2012, print issue of Neurology, the medical journal of the American Academy of Neurology. ...> Full Article


Women should still be concerned about hormone replacement therapy, say McMaster researchers (12/23/2011)

This study comes at a time when more women are again asking for this medication to control hot flashes and other symptoms of menopause. ...> Full Article


Eating less keeps the brain young (12/22/2011)

Overeating may cause brain aging while eating less turns on a molecule that helps the brain stay young. A team of Italian researchers at the Catholic University of Sacred Heart in Rome have discovered that this molecule, called CREB1, is triggered by "caloric restriction" in the brain of mice. They found that CREB1 activates many genes linked to longevity and to the proper functioning of the brain. ...> Full Article


Brain function - A new way to measure the burden of aging across nations (12/21/2011)

Cognitive function may be a better indicator of the impact of aging on an economy than age-distribution, with chronological age imposing less of a social and economic burden if the population is "functionally" younger, according to a study published today in the Proceedings of the National Academy of Sciences. ...> Full Article


Knee pain common complaint in middle-aged and mature women (12/20/2011)

New research shows 63 percent of women age 50 and older reported persistent, incident, or intermittent knee pain during a 12-year study period. Predictors for persistent pain included higher body mass index, previous knee injury, and radiographic osteoarthritis. Details of this longitudinal study are available in Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology. ...> Full Article


Outwit the Grim Reaper by walking faster (12/17/2011)

'Tis the season to be wary of elder financial abuse (12/16/2011)

'Tis the season to be wary of elder financial abuseSeniors should be advised that, along with seasonal elevations of joy and good cheer, the risk of falling victim to elder financial abuse is also increasing, researchers report. ...> Full Article


Research could help people with declining sense of smell (12/9/2011)

Research could help people with declining sense of smellCells in the nose ? smell sensors, primarily ? are constantly replaced as old ones die off. Olfactory stem cells are the source for these new cells, but how do they determine when to form mature cells? UC Berkeley neuroscientist John Ngai and colleague Russell Fletcher have found a genetic trigger ? a transcription factor ? that acts as a brake on differentiation. Removing it makes stem cells change into mature olfactory cells at the expense of self-renewal. ...> Full Article


New research aims to shed light on how aging affects immunity (12/2/2011)

Efforts to understand the effect of aging on the immune system received a boost today as the Biotechnology and Biological Sciences Research Council announced investment in a new 3.6 million research project. ...> Full Article


A study looks at the nature of change in our aging, changing brains (12/1/2011)

As we get older, our cognitive abilities change, improving when we're younger and declining as we age. Scientists posit a hierarchical structure within which these abilities are organized. There's the "lowest" level -- measured by specific tests, such as story memory or word memory; the second level, which groups various skills involved in a category of cognitive ability, such as memory, perceptual speed, or reasoning; and finally, the "general," or G, factor, a sort of statistical aggregate of all the thinking abilities. ...> Full Article
