Sleep quality and duration improve cognition in aging populations (6/18/2014)

Sleep quality and duration improve cognition in aging populationsMaybe turning to sleep gadgets -- wristbands, sound therapy and sleep-monitoring smartphone apps -- is a good idea. A new University of Oregon-led study of middle-aged or older people who get six to nine hours of sleep a night think better than those sleeping fewer or more hours. ...> Full Article


UTMB to participate in $30 million national study to prevent falls in older people (6/17/2014)

Each year, 1 out of 3 adults 65 and older will fall, sustaining injuries that can lead to a precipitous decline in health, loss of independence, even death. Seeking new ways to address the personal and public health burden of these falls, the University of Texas Medical Branch at Galveston is participating, along with nine other clinical health system sites across the country, in a clinical trial to test individually tailored interventions for preventing fall-related injuries. ...> Full Article


6,000 steps a day keeps knee OA limitations away (6/15/2014)

6,000 steps a day keeps knee OA limitations awayA new study shows that walking reduces risk of functional limitation associated with knee osteoarthritis. In fact, the study funded in part by grants from the National Institutes of Health and published in the American College of Rheumatology journal, Arthritis Care & Research, suggests that walking 6,000 or more steps per day may protect those with or at risk of knee of OA from developing mobility issues, such as difficulty getting up from a chair and climbing stairs. ...> Full Article


Football for untrained 70-year-old men (6/14/2014)

Research carried out by the Copenhagen Centre for Team Sport and Health in Denmark shows that untrained elderly men get markedly fitter and healthier as a result of playing soccer. After only four months of twice-weekly one-hour training sessions, the men achieved marked improvements in maximum oxygen uptake, muscle function and bone mineralization. ...> Full Article

Exploring a legal and ethical gray area for people with dementia (6/12/2014)

Many of the legal and ethical options for refusing unwanted interventions are not available to people with dementia because they lack decision-making capacity. But one way for these people to ensure that they do not live for years with severe dementia is to use an advance directive to instruct caregivers to stop giving them food and water by mouth. This is an ethical and legal gray area explored in commentaries and a case study in the Hastings Center Report. ...> Full Article


A new diagnostic tool for dementia diseases (6/11/2014)

A new diagnostic tool helps clinicians to differentiate between Alzheimer's disease, frontotemporal dementia and mild cognitive impairment. Presented in the doctoral thesis of MD Miguel Ángel Muñoz Ruiz at the University of Eastern Finland, the new method consists of a Disease State Index combining data from multiple sources, and of a Disease State Fingerprint showing the findings in a visual format. ...> Full Article


New health services needed for rise in 100-year-olds (6/10/2014)

Over 35,000 people lived to 100 years or more in England over the last ten years, with a large proportion subsequently dying from frailty exacerbated by pneumonia, according to a new study by King's College London. With the number of centenarians set to grow, end-of-life care needs to be tailored to the increasing frailty in this age group, warn the King's palliative care researchers. ...> Full Article

Negative social interactions increase hypertension risk in older adults (6/5/2014)

Keeping your friends close and your enemies closer may not be the best advice if you are 50 or older. New research from Carnegie Mellon University's Rodlescia Sneed and Sheldon Cohen shows that unpleasant or demanding interpersonal encounters increase hypertension risk among older adults. Published in the American Psychological Association's Health Psychology Journal, the study provides some of the first concrete evidence that negative social interactions not only influence psychological well-being but also physical health -- in this case, blood pressure levels. ...> Full Article


Can Tai Chi slow the aging process? (6/4/2014)

Evaluating the potential life-lengthening effect of Tai Chi, a traditional Chinese exercise, researchers conducted a year-long study comparing rejuvenating and anti-aging effects among three groups of young volunteers engaged in Tai Chi, brisk walking, or no exercise. The group performing Tai Chi saw a rise in their CD34+ cells, important to a number of the body's functions and structures. Researchers speculate that Tai Chi may have boosted vasodilation and increased blood flow for that group. ...> Full Article
