Older adult’s perceived cognitive decline may be related to changes in brain functional connectivity

Jessica Damoiseaux, Ph.D., an associate professor with the Institute of Gerontology at Wayne State University, recently published the results of a three-year study of cognitive changes in older adults. The team followed 69 primarily African American females, ages 50 to 85, who complained that their cognitive ability was worsening though clinical assessments showed no impairments.

Brain study may lead to new treatments for neuro-immune conditions

The immune system is the brain's best frenemy. It protects the brain from infection and helps injured tissues heal, but it also causes autoimmune diseases and creates inflammation that drives neurodegeneration. Two new studies in mice suggest that the double-edged nature of the relationship between the immune system and the brain may come down to

Caring for an aging nation

Health care for the nation's seniors looms large as the baby-boom generation ages into retirement. President Joe Biden tacitly acknowledged those needs in March with his proposal to spend $400 billion over the next eight years to improve access to in-home and community-based care. The swelling population of seniors will far outpace growth in other

Study: Specific diet, lifestyle interventions may reverse epigenetic aging in healthy adult males

Aging published "Potential reversal of epigenetic age using a diet and lifestyle intervention: a pilot randomized clinical trial" which reported on a randomized controlled clinical trial conducted among 43 healthy adult males between the ages of 50-72. The 8-week treatment program included diet, sleep, exercise and relaxation guidance, and supplemental probiotics and phytonutrients. Genome-wide DNA

Chaperone protein imbalance promotes toxic tau buildup in the aging brain

Chaperone protein imbalance can play a significant role in initiating toxic accumulation of tau in the aging brain—an early step in the development of Alzheimer’s disease and related neurodegenerative disorders known as tauopathies, a new preclinical study by University of South Florida Health (USF Health) neuroscientists suggests. In humans, misfolding of the protein tau leads

The Science Behind Face Yoga

"The Cheek Lifter" and "The Happy Cheek Sculpter” may sound like phrases out of an ‘80s exercise video, and they definitely sound like they apply to your non-facial cheeks. But according to dermatologists and facialists, these facial exercises — also known as face yoga — may help the face appear more taut and sculpted. Back

Genetic background may affect adaptions to aging

How we adapt to aging late in life may be genetically influenced, according to a study led by a psychologist at the University of California, Riverside. The research, published in Aging Cell, has implications for how epigenetic factors relate to aging. Epigenesis is a process in which chemicals attached to DNA control its activity. Epigenetic

Does aging make our brains less efficient?

We are an aging population. Demographic projections predict the largest population growth will be in the oldest age group—one study predicted a doubling of people age 65 and over between 2012 and 2050. Understanding aging and prolonging healthy years is thus becoming increasingly important. For Michele Diaz, Ph.D., of Pennsylvania State University, understanding aging is

Frailty is a medical condition, not an inevitable result of aging

Frailty is not simply an adjective associated with old age, it is a medical condition all on its own. And it has significant medical, social and economic implications. A landmark study published today (August 2) in the Journal of the American Medical Association (JAMA) Network Open, led by researchers at Monash University in Australia, explored

Fasting boosts metabolism and fights aging

Studies have shown that intermittent fasting can help certain people lose weight. Although researchers are still debating exactly how effective fasting can be for weight loss, new research hints at other benefits. In rats, for instance, studies show that fasting can increase lifespan. Although exciting, evidence of this in humans has yet to be seen.

Enzyme that breaks down amino acids may promote aging

Permanently arrested cell growth is known as “cellular senescence”, and the accumulation of senescent cells may be one cause of aging in our bodies. Japanese researchers have discovered that a certain enzyme in our bodies promotes cellular senescence by producing reactive oxygen species. Drugs that target this enzyme could potentially suppress this process, and inhibit
