Healthy Lifestyle May Buffer Against Stress-Related Cell Aging

A new study from UC San Francisco is the first to show that while the impact of life’s stressors accumulate overtime and accelerate cellular aging, these negative effects may be reduced by maintaining a healthy diet, exercising and sleeping well.

Slow Walking Speed and Memory Complaints Can Predict Dementia

A study involving nearly 27,000 older adults on five continents found that nearly 1 in 10 met criteria for pre-dementia based on a simple test that measures how fast people walk and whether they have cognitive complaints. People who tested positive for pre-dementia were twice as likely as others to develop dementia within 12 years. The study, led by scientists at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center, was published online on July 16, 2014 in Neurology®, the medical journal of the American Academy of Neurology.

Age-Related Macular Degeneration—Optometry and Vision Science Presents Research Update

Original_00006324-201408000-00001_F21_1.jpg

Recent years have seen major strides in basic science and clinical research on age-related macular degeneration (AMD)—the leading cause of vision loss in older adults. The August issue of Optometry and Vision Science, official journal of the American Academy of Optometry, is a theme issue devoted to advances and challenges in AMD research. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Strategy Proposed for Preventing Diseases of Aging

Researchers at Washington University School of Medicine in St. Louis and elsewhere argue that medicine focuses too much on fighting diseases individually instead of concentrating on interventions that prevent multiple chronic diseases and extend healthy lifespan. They call for moving forward with strategies that have been shown to delay aging in animals. In addition to promoting a healthy diet and regular exercise, these strategies include manipulating molecular pathways that slow aging and promote healthy longevity.

Life Expectancy Gains Threatened as More Older Americans Suffer From Multiple Medical Conditions

With nearly four in five older Americans living with multiple chronic medical conditions, a new study by researchers at Johns Hopkins Bloomberg School of Public Health finds that the more ailments you have after retirement age, the shorter your life expectancy. The analysis, one of the first to examine the burden of multiple chronic conditions on life expectancy among the elderly, may help explain why increases in life expectancy among older Americans are slowing.

Scripps Florida Scientists Identify Gene That Plays a Surprising Role in Combating Aging

Scientists from The Scripps Research Institute have found in animal models that a single gene plays a surprising role in aging, a discovery that could lead to the possibility of using therapeutics, even commonly used ones, to manipulate the aging process itself.

Millions of Informal Caregivers at Risk for Chronic Pain, Injury Trying to Help Disabled Family Members

According to a recent report from AARP’s Public Policy Institute, unpaid, informal caregivers provide almost half a trillion dollars’ worth of support to individuals with disabilities each year. These caregivers - usually family members - often perform physically-demanding tasks with little or no training, which can result in muscle strains and chronic pain. With very little data on the physical impact of informal caregiving, new research is identifying which tasks caregivers say are the most physically demanding and where they experience the most body pain. Researchers are using the information to develop interventions to help keep caregivers and their loved ones safe and healthy.

National Health Org Says Tremors, Shuffling and Confusion May Not Be Parkinson’s but LBD

Lewy Body Dementia Association (LBDA) highlights the importance of an accurate Lewy body dementia diagnosis, which may have life-saving implications. Affecting more than 1.3 million Americans, Lewy body dementia (LBD) is the most misdiagnosed form of dementia and, following Alzheimer’s disease, is the second most common cause of progressive dementia. LBD is associated with abnormal protein deposits in the brain, called Lewy bodies, that affect thinking, movement, behavior and mood. It’s difficult to diagnose LBD, because its early symptoms resemble those found in Alzheimer’s and Parkinson’s disease.

How Aging Can Intensify Damage of Spinal Cord Injury

In the complex environment of a spinal cord injury, researchers have found that immune cells in the central nervous system of elderly mice fail to activate an important signaling pathway, dramatically lowering chances for repair after injury.
