UC San Diego researchers find stem cells use a surprising system for discarding misfolded proteins. This unique pathway could be the key to maintaining long-term health and preventing age-related blood and immune disorders.
Patients with a family history of age-related macular degeneration (AMD), the leading cause of permanent vision loss in those older than 60, should visit an ophthalmologist by age 55 to be screened for signs of the disease, advises an expert at UT Southwestern Medical Center.
University of Delaware associate professor Matthew Cohen offers 11 signs and symptoms that might suggest a health condition, such as dementia, that affects thinking. Cohen is associate director of the Delaware Center for Cognitive Aging Research.
Cancer and its treatment can accelerate the rate of aging because they both destabilize and damage biological systems in the body.
Staphylococcus aureus, Clostridioides difficile, Candida auris, Drug-resistant Shigella. These bacteria not only have difficult names to pronounce, but they are also difficult to fight off. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. Antimicrobial resistance is an urgent global public health threat.
Walking is a complex task that is most commonly performed while completing other tasks like talking, reading signs, or making decisions.
A new study led by researchers at York University has found a link between shift work and frailty among middle-aged and older workers in Canada, especially for women on rotating shifts.
Physical exercise can help to improve the severity of movement-related symptoms and the quality of life in people with Parkinson’s Disease. Findings from the first Cochrane review of the available evidence found that any type of structured exercise is better than none.
It's sleep awareness week, according to the National Sleep Foundation. It’s important to understand how sleep deprivation can impact your health. Most people recognize that if they don’t get enough sleep, their mood and memory will suffer the next day.
It started with a hunt for lab space and ended with a collaboration born out of what the researchers call a “cosmic coincidence.”
The risk of death rises among older adults with Alzheimer's or other dementias in the months following exposure to a hurricane, a new University of Michigan study shows.
After three years of pandemic living, loneliness, isolation and lack of social contact have finally started to decline among older adults, a new poll shows.
The review did not find any compelling evidence for other measures to reduce falls, such as making sure older people have the correct prescription glasses, special footwear, or education on avoiding falls.
University of Virginia scientists have identified a promising approach to delay aging by detoxifying the body of glycerol and glyceraldehyde, harmful by-products of fat that naturally accumulate over time.
Keck Medicine of USC has launched a clinical trial to study the effect of a novel hormone replacement therapy on postmenopausal cardiovascular disease and cognitive decline.
Scientists from the Trinity Biomedical Sciences Institute (TBSI) have shed new light on ageing processes in the brain. By linking the increased presence of specialised immune cells to conditions such as Alzheimer’s disease and traumatic brain injury for the first time, they have unearthed a possible new target for therapies aimed at treating age-related neurological diseases.
A new study by the University of Missouri and Oklahoma State University found that even when gyms were closed and there were other COVID-19 restrictions limiting face-to-face meetings, older adults who completed the Stay Strong, Stay Healthy exercise program — created at MU in 2005 — continued to maintain long-term exercise habits independently, which resulted in improved lifestyle changes and an increase in both physical energy and self-confidence.
Scientific evidence shows how the cognitive decline in Alzheimer’s disease (AD) is caused by the buildup of amyloid beta proteins, which promote synaptic malfunction.
Because females 65 and older have an increased rate of falls and facial fractures, researchers compared the risk of skull fracture secondary to head trauma in geriatric female and male patients. Results showed that males had a significantly increased incidence of skull fracture secondary to head trauma, due mostly to falls. This outcome was unexpected, as previous research has indicated females are more susceptible to facial fractures. This trend also was seen across race/ethnicity, though results were only statistically significant for whites.
Adding to the growing body of evidence on sleep disturbances and cognitive impairment, new research finds significant links between three measures of sleep disturbance and the risk for developing dementia over a 10-year period.
