Scientists have long known that getting enough sleep is important for brain health. Poor sleep has been linked to problems with memory, concentration, and mood. Over the past several years, researchers have also discovered that sleep may play an important role in the development of Alzheimer’s disease, the most common form of dementia. Now, a […] The post How Sleep and AQP4 Gene Variants May Shap…

For many older adults, glucosamine is a familiar name. The supplement is widely advertised as a way to support joint health and ease pain from arthritis. Because it is sold without a prescription and has been used by millions of people for years, many consumers view it as a safe and natural product. However, new […] The post Common Arthritis Supplement Linked to Faster Alzheimer’s Development app…

A new Review reveals how aging can push the immune system into a paradoxical state, weaker against threats yet more prone to attacking the body’s own tissues.

Researchers have identified a gene that appears to balance a powerful evolutionary trade-off, boosting growth and reproductive success early in life while carrying hidden costs later on. The biological processes that help build a healthy young body may also sow the seeds of aging and cancer. Researchers have now identified a gene that appears to [...]

We propose a roadmap to guide research and innovation integrating replacement and next-generation damage-removal therapeutics to modulate the ageing process in the whole body, restore biological function, and extend healthy lifespan.

A study of long-lived families has identified rare genetic variants that may help people stay healthier for much longer as they age. One standout mutation appears to temper inflammation, potentially delaying disease and extending years of healthy living.

Many people notice changes in their bodies as they get older. They may find it harder to climb stairs, stand up from a chair, walk long distances, or carry shopping bags. Loss of strength is one of the most common problems that comes with aging. For many years, scientists and doctors believed that older adults […] The post What Causes Muscle Weakness in Older People? appeared first on Knowridge S…

A long-term Yale study is challenging one of the biggest myths about aging. Nearly half of adults over 65 improved physically, mentally, or both over time, despite the common belief that aging means constant decline. Researchers found that people with more positive attitudes about getting older were significantly more likely to show these gains.

When older adults undergo surgery, doctors often focus on complications such as infections, bleeding, or heart problems. Yet one of the most common complications affects the brain. Known as postoperative delirium, this condition can cause sudden confusion, disorientation, memory difficulties, and changes in behavior. Many families assume that delirium is temporary. In some cases, symptoms […] The…

Growing older often brings aches and pains, especially in the knees, hips, and other joints that carry the body’s weight. For many people, these problems are caused by osteoarthritis, a disease that slowly destroys cartilage. Cartilage acts like a natural cushion inside joints, allowing bones to move smoothly without friction. When cartilage breaks down, joints […] The post New Anti-Aging Discove…

Can dietary improvements restore mental performance after periods of unhealthy eating?

For many older adults, leaving the hospital is only the beginning of recovery. A serious illness, surgery, or injury can have lasting effects on the body. Even a short hospital stay can lead to weakness and loss of muscle. Older adults may suddenly find that activities they once did easily have become difficult. Walking to […] The post A New Way to Help Frail Older People Regain Independence appe…

Source: Google News - Health If you're taking an omega-3 fish oil supplement to prevent Alzheimer's disease and dementia, take note: A new study has found these supplements do not improve memory, cognition, or brain cell loss. The study was a randomized, double-blind, placebo-controlled clinical trial—the gold standard of science—published in The Lancet journal ebioMedicine. What does work? Exerc…

Abstract Purpose To investigate body composition as a predictive biomarker of cancer-related death in patients with non-metastatic colon cancer (CRC). Materials and methods Patients with CRC (stages II–III) treated with upfront surgery, with availability of baseline CT, clinico-histological and survival data were retrospectively enrolled. Patients with stage IV or CT unavailability were excluded.…

The aim of this retrospective study was to identify if malnutrition in older adults was linked to poor outcomes. A total of 327 inpatients aged ≥65 years who were referred for geriatric consultation were evaluated. At baseline, 56.8% received no nutritional support. After geriatric evaluation, 53% were started on oral nutrition supplements (ONS). In-hospital mortality was 14.1%. ONS use was assoc…

Background: After cardiac valve replacement surgery, there is a pronounced inflammatory response and heightened metabolic rate. The adequacy of nutrition may affect immune modulation, recovery parameters, and quality of life (QOL), but there is a paucity of combined prospective data. Objective: To assess the effect of postoperative nutritional status on inflammation, recovery, and QOL in patients…

Introduction: Cachexia is a complex syndrome marked by progressive loss of muscle and fat, leading to functional decline and reduced Quality of Life (QoL). The impact of cachexia in Head and Neck Cancer (HNC) remains an underexplored area. They are particularly vulnerable because of swallowing difficulties and early weight loss, which predispose them to cachexia even at diagnosis. Since conventio…
