In a study of nearly 3,000 people, Einstein researchers have found that those who live 95 years or more are able to stave off age-related disease, with serious sickness compressed into only a few years late in life.
A European study led by Umeå University Professor Lars Nyberg, has shown that the dopamine D2 receptor is linked to the long-term episodic memory, which function often reduces with age and due to dementia. This new insight can contribute to the understanding of why some but not others are affected by memory impairment. The results have been published in the journal PNAS.
UT Southwestern Medical Center cell biologists have identified a new method for determining the length of telomeres, the endcaps of chromosomes, which can influence cancer progression and aging.
New research from the University of British Columbia shows a higher risk of mortality during extreme heat events in neighbourhoods that tend to get hotter and where people tend to be poorer.
The immune system in the elderly is dysfunctional and infections are more prevalent, more severe, and harder to defeat. Drinking alcohol has a variety of damaging effects on the immune system and organs – like the gut, liver and lung – which can be worsened by pre-existing conditions as well as consumption of prescription and over-the-counter medications that aged individuals often take. This presentation addresses how alcohol affects the elderly more dramatically, and also suppresses their ability to battle infections, like pneumonia, much more severely than it does younger individuals.
Researchers have developed an index to better predict which women may experience faster bone loss across the menopause transition, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
Older adults experience deficits in inhibition, which can affect how quickly they process information visually, according to a new study involving the University of Arizona.
The 39th annual Research Society on Alcoholism Scientific Meeting will take place June 25-29 in New Orleans, Louisiana. RSA 2016 provides a meeting place for scientists and clinicians from across the country, and around the world, to interact. The meeting also gives members and non-members the chance to present their latest findings in alcohol research through abstract and symposia submissions.
ROCHESTER, Minn. — The incidence of Parkinson’s disease and parkinsonism increased significantly in 30 years from 1976 to 2005, Mayo Clinic researchers reported today in a study in JAMA Neurology. This trend was noted in particular for men age 70 and older. According to the researchers, this is the first study to suggest such an increasing trend.
Exercise may have some surprising benefits for seniors who experience rapid muscle loss and muscle injury and loss as they age. Researchers at McMaster University have found that physical activity can help retain, even repair and regenerate damaged muscle in the elderly.
The findings challenge what is generally seen as an inevitable fact of life: that muscle atrophy and damage cannot be completely repaired in old age and in some cases lost altogether.
As young people reach adulthood, their preferences for sweet foods typically decline. But a Washington University School of Medicine research team, led by M. Yanina Pepino, PhD, and Tamara Hershey, PhD, has found that for people with obesity, the drop-off may not be as steep, and the brain’s reward system may be operating differently.
Women live longer than men. This simple statement holds a tantalizing riddle that Steven Austad, Ph.D., and Kathleen Fischer, Ph.D., of the University of Alabama at Birmingham explore in a perspective piece published in Cell Metabolism on June 14.
Researchers at Mayo Clinic have developed an accurate way to measure a circulating factor, called GDF11, to better understand its potential impact on the aging process. They found that GDF11 levels do not decline with chronological age, but are associated with signs of advanced biological age, including chronic disease, frailty and greater operative risk in older adults with cardiovascular disease. Results appear today in Cell Metabolism.
Researchers at Mayo Clinic have identified the enzyme, called CD38, that is responsible for the decrease in nicotinamide adenine dinucleotide (NAD) during aging, a process that is associated with age-related metabolic decline. Results demonstrated an increase in the presence of CD38 with aging in both mice and humans. The results appear today in Cell Metabolism.
Although brains—even adult brains—are far more malleable than we used to think, they are eventually subject to age-related illnesses, like dementia, and loss of cognitive function. Someday, though, we may actually be able to replace brain cells and restore memory.
Siobhan Malany, Ph.D., director of Translational Biology at Sanford Burnham Prebys Medical Discovery Institute at Lake Nona (SBP) and founder of the Institute’s first spin-off company, Micro-gRx, Inc., has been awarded $435,000 to study atrophy in muscle cells in microgravity on the International Space Station (ISS).
Young people are less likely to be ageist when their friends have friendships with older adults, research led by psychologists at the University of Kent has shown.
Dr. John Hatle, a professor in the Department of Biology at the University of North Florida, was awarded a grant for more than $430,000 by the National Institutes of Health to continue his research studying how a reduced diet can slow aging and extend lifespan in simple animals.
Wolters Kluwer, a leading global provider of information and point of care solutions for the healthcare industry, is pleased to announce a new publishing partnership with the open access journal, Healthy Aging Research.
Research has found that hearing loss has wide-ranging impacts not only on older people's ability to communicate, but also on their ability to move about and participate in different hobbies and activities. This has been revealed in studies funded by the Academy of Finland whose results have been published in international scientific journals.
Developing and evaluating motion-capture technology to help older adults “age in place” has been the focus of researchers at the University of Missouri for more than a decade. Previous research has utilized video game technology and various web-cameras to detect health changes in Tiger Place residents. Now, two new studies demonstrate how monitoring walking speed using radar and heart health by utilizing bed sensors help maintain older adults’ health and warn of impeding issues.
Visual blurring—like that produced by bifocals or multifocal lenses—may cause errors in foot position when walking. And that could contribute to the risk of tripping and falling in older adults, suggests a study in the June issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.
A dietary supplement containing a blend of thirty vitamins and minerals—all natural ingredients widely available in health food stores—has shown remarkable anti-aging properties that can prevent and even reverse massive brain cell loss, according to new research from McMaster University.
It’s a mixture scientists believe could someday slow the progress of catastrophic neurological diseases such as Alzheimer’s, ALS and Parkinson’s.
Brian Balin, PhD, has studied the link between infection and Alzheimer's disease for more than 20 years and offers his thoughts on this growing area of research.
While the evidence behind this age-related weakening of the circadian rhythm has been established in medical literature, the mechanisms behind it, and the connectivity structure of the neurons, have remained elusive. To better understand these neuronal and hormonal mechanisms and help develop potential treatments, researchers have conducted experimental analyses of the SCN’s connections, with the goal of determining its degree of heterogeneity. They discuss their work in this week’s CHAOS.
Social and economic disadvantages play a significant role in why blacks face a much higher risk than whites of developing cognitive impairment later in life, indicates a national study led by a Michigan State University (MSU) sociologist.

Researchers found that individuals who maintain an active jogging habit into their senior years are spending nearly the same amount of metabolic energy as a 20-year-old.
The visible impacts of depression and stress that can be seen in a person's face -- and contribute to shorter lives -- can also be found in alterations in genetic activity, according to newly published research from the Indiana University School of Medicine and the Scripps Research Institute.
In a paper published in the current Journal of Alzheimer’s Disease, researchers at University of California San Diego School of Medicine and Veterans Affairs San Diego Healthcare System say existing screening tools for mild cognitive impairment (MCI) result in a false-negative error rate of more than 7 percent. These persons are misclassified as not having MCI based on standard screening instruments but actually do have MCI when more extensive testing is conducted.
UCLA neuroscientists have identified in mice how the brain links different memories over time. The findings suggest a possible intervention for people suffering from age-related memory problems.
Why We Get Tired When We Stay Up Too Late, Pain and Anxiety Drug Linked to Birth Defects, Old Drug Could Fight Brain Cancer and more in the Neuroscience and Neurology News Source
Intensive therapies to reduce high blood pressure can cut the risk of heart disease in older adults without increasing the risk for falls, according to doctors at Wake Forest Baptist Medical Center.
A new study from Uppsala University shows that compared to non-shift workers, shift workers needed more time to complete a test that is frequently used by physicians to screen for cognitive impairment. However, those who had quit shift work more than five years ago completed the test just as quick as the non-shift workers. The findings are published in the journal Neurobiology of Aging.
Being fit may reduce the decline in lung function that occurs as we grow older, according to research presented at the ATS 2016 International Conference.
Research from the University of Kentucky College of Health Sciences was able to demonstrate a positive correlation between fitness and blood flow to areas of the brain where the hallmark tangles and plaques of Alzheimer’s disease pathology are usually first detected, indicating a possibility that regular exercise could stave off AD symptoms.
Chronological age itself plays almost no role in accounting for differences in older people’s health and well-being, according to a new, large-scale study by a multidisciplinary team of researchers at the University of Chicago.
Tricuspid regurgitation (TR) occurs when the heart’s tricuspid valve leaks, allowing blood to flow back from the right ventricle to the right atrium. TR can be secondary to disorders of left-sided heart valves (mitral or aortic). At the 96th AATS Annual Meeting, investigators present the results of a long-term study of patients who underwent mitral valve (MV) repair. They found that although newly developed TR after MV repair was rare, the risk could increase in older patients with atrial fibrillation and impaired heart function.
Nearly 30 years of data collected on painted turtles in the Mississippi River near Clinton, Iowa, show that females suffer a steep dip in fertility before the end of their lives, a finding that flies in the face of what scientists have believed about turtles and aging.
