A major cause of age-related memory loss identified (8/31/2013)

A major cause of age-related memory loss identifiedA team of Columbia University Medical Center researchers, led by Nobel laureate Eric R. Kandel, MD, has found that deficiency of a protein called RbAp48 in the hippocampus is a significant contributor to age-related memory loss and that this form of memory loss is reversible. The study, conducted in postmortem human brain cells and in mice, also offers the strongest causal evidence that age-related memory loss and Alzheimer's disease are distinct conditions. ...> Full Article


Better management of free time ensures happier retirement (8/24/2013)

Retirees should be masters of their own destiny, and actively manage and plan their free time to ensure a happy and fulfilling retirement. This is the advice from a study published in Springer's journal Applied Research in Quality of Life. The study found that the effective management of free time has a far greater impact on a retiree's quality of life than the amount of time the person actually has available for leisure activities. ...> Full Article

Researchers report a critical role for the complement system in early macular degeneration (8/18/2013)

Mass. Eye and Ear Ocular Genomics Institute researchers report the unexpected finding that in mice genetically engineered to have an inherited form of macular degeneration, turning off the animals' complement system, a part of the immune system, prevented the disease. ...> Full Article


Virtual adviser helps older Latino adults get more exercise, Stanford researcher says (8/17/2013)

Solutions for improving first aid in cardiorespiratory arrests (8/16/2013)

Solutions for improving first aid in cardiorespiratory arrestsAn algorithm capable of diagnosing heart rhythm with just 3 seconds' worth of signal, and the demonstration that it is possible to come up with the diagnosis without stopping cardiac massage, constitute the types of solutions and proposals being developed by researchers in the Signal and Communications Group of the Faculty of Engineering in Bilbao. ...> Full Article


Your eyes may hold clues to stroke risk (8/15/2013)

Photographing the retina may help detect which high blood pressure patients are more likely to have a stroke. Retinal imaging may be an inexpensive and non-invasive way to assess risk. ...> Full Article


From Einstein to Oprah: Famous faces may help spot early dementia (8/14/2013)

A new study suggests that simple tests that measure the ability to recognize and name famous people such as Albert Einstein, Bill Gates or Oprah Winfrey may help doctors identify early dementia in those 40 to 65 years of age. The research appears in the Aug. 13, 2013, print issue of Neurology, the medical journal of the American Academy of Neurology. ...> Full Article


Dementia risk tied to blood sugar level, even with no diabetes (8/11/2013)

Dementia risk tied to blood sugar level, even with no diabetesDiabetes is a risk factor for dementia. But now a joint Group Health?University of Washington study in the New England Journal of Medicine has found that higher blood sugar levels are associated with higher dementia risk, even among people who do not have diabetes. The higher the blood sugar level, averaged over five years, the higher the risk for developing dementia, in this report about more than 2,000 Group Health patients. ...> Full Article


Cognitive decline with age is normal, routine -- but not inevitable (8/10/2013)

Research on biochemical processes is making it clear that cognitive decline with age is a natural part of life, and scientists are tracking the problem down to highly specific components of the brain. Virtually everyone loses memory-making and cognitive abilities as they age. But of considerable interest is that it may not have to be that way. ...> Full Article


Driving simulation and cognitive models reveal differences between novice and experienced drivers (8/9/2013)

Driving simulation and cognitive models reveal differences between novice and experienced driversDriving experience is a critical human factor of driving safety. A recent study examined the differences between novice and experienced drivers using a driving simulator and modeled the differences using computational cognitive models. The method and results provide support and cognitive bases for developing intelligent driver training and driving assistance systems. This study has been published on CHINESE SCIENCE BULLETIN recently. ...> Full Article


Necrostatin-1 counteracts aluminum's neurotoxic effects (8/8/2013)

Investigators have linked aluminum accumulation in the brain as a possible contributing factor to neurodegenerative disorders such as Alzheimer's disease. A new study published in Restorative Neurology and Neuroscience sheds light on the mechanism underlying aluminum-induced neuronal cell death and identifies necrostatin-1 as a substance which counteracts several of aluminum's neurotoxic effects. ...> Full Article


Not only bone density, but also quality of bone predicts fracture risk (8/7/2013)

Not only bone density, but also quality of bone predicts fracture riskIn a study carried out at the University of Eastern Finland, bone histomorphometry and infrared spectroscopy revealed abnormal bone properties in children with vertebral fractures and in children after solid organ transplantation. Bone compositional changes in children with vertebral fractures and after different types of organ transplantation have not been reported previously. ...> Full Article

Requiring some patients to get mental health treatment saves money (8/4/2013)

Mandating outpatient treatment for certain people with severe mental illness, while controversial, results in substantial cost savings by cutting hospitalizations and increasing outpatient care, according to a financial analysis led by researchers at Duke Medicine. ...> Full Article


Severe low blood sugar occurs often in patients with Type 2 diabetes (8/3/2013)

Patients with diabetes who take certain types of medications to lower their blood sugar sometimes experience severe low blood sugar levels, whether or not their diabetes is poorly or well controlled, according to a new study by Kaiser Permanente and Yale University School of Medicine. The finding, published in the current online issue of Diabetes Care, challenges the conventional wisdom that hypoglycemia is primarily a problem among diabetic patients with well-controlled diabetes (who have low average blood sugar levels). ...> Full Article


A smart way of using testosterone to prevent muscle wasting (8/2/2013)

New Australian research suggests that a small dose of testosterone directed solely to the liver stimulates protein synthesis, likely preventing muscle loss and wasting, and potentially promoting muscle growth. The researchers believe they have developed a safe and effective treatment for men and women, that could prevent the muscle wasting associated with many chronic diseases and with aging. ...> Full Article
