A meta-analysis finds that vision impairment and blindness are tied to an increased risk of mortality, prompting the need to address global eye health disparities.

Researchers have developed a method based on artificial intelligence that rapidly identifies currently available medications that may treat Alzheimer's disease. The method also reveals potential new treatment targets for the disease.

Scientists have developed a method that can determine an organism's biological age with unprecedented precision. Researchers expect new insights into how the environment, nutrition, and therapies influence the aging process.

Researchers have identified a new drug that could prevent AD by modulating, rather than inhibiting, a key enzyme involved in forming amyloid plaques.

Researchers describe a new vaccination strategy that they think could re-program the body to fight off the bacteria that cause urinary tract infections.

A research team has discovered two new genes potentially involved in Alzheimer's disease. They identified them by exploring which genes were turned on and off in the hippocampus of people who suffered from the disease.

A DNA-damaging bacterial toxin called colibactin is produced in patients with urinary tract infections (UTIs), according to a new study.

Research shows that Soldiers exposed to shockwaves from military explosives are at a higher risk for developing Alzheimer's disease -- even those that don't have traumatic brain injuries from those blasts. A new study identifies how those blasts affect the brain.

Research suggests that light-intensity physical activity, including shopping or a casual walk, may protect against mobility disability in older women.

A new study suggests that a hormone known to prevent weight gain and normalize metabolism can also help maintain healthy muscles in mice. The findings present new possibilities for treating muscle-wasting conditions associated with age, obesity or cancer, according to scientists.

A unique brain protein measured in the blood could be used to diagnose Alzheimer's disease decades before symptoms develop, according to new Edith Cowan University (ECU) research.

The gut microbiome is an integral component of the body, but its importance in the human aging process is unclear. Researchers have identified distinct signatures in the gut microbiome that are associated with either healthy or unhealthy aging trajectories, which in turn predict survival in a population of older individuals.

New research on tiny capillaries and cells called pericytes details how blood moves through over 400 miles of total vasculature in the human brain.

A new pair of studies make the case that early-life mental health problems can lead to physical diseases and advanced aging in adulthood. But because mental health conditions can appear early in life, the researchers say that investment in prompt mental health care could be used to prevent later diseases and reduce healthcare costs.

Scientists found that five genes may play a critical role in determining whether a person will suffer from Lewy body dementia, a devastating disorder that riddles the brain with clumps of abnormal protein deposits called Lewy bodies. The results also supported the disorder's ties to Parkinson's and Alzheimer diseases.

Researchers are studying how different patterns in the way older adults walk could more accurately diagnose different types of dementia and identify Alzheimer's disease.

Researchers have identified the role a critical enzyme plays in skeletal aging and bone loss, putting them one step closer to understanding the complex biological mechanisms that lead to osteoporosis, the bone disease that afflicts some 200 million people worldwide. Findings could hold an important key to developing more effective treatments for osteoporosis and improving the lives of an aging population.

Researchers have developed and validated, SymTrak-8, a short questionnaire to help patients report symptoms and assist healthcare providers in assessing the severity of symptoms, and in monitoring and adjusting treatment accordingly.

Researchers have developed a machine-learning approach to identify drugs that could be repurposed to fight COVID-19. The advance could boost clinical trial efforts, and it could be adapted to a broader range of diseases.

Researchers analyzed data from the UK Biobank of 500,000 people aged 58 years on average, and found that people with higher than normal blood sugar levels were 42% more likely to experience cognitive decline over an average of four years, and were 54% more likely to develop vascular dementia over an average of eight years (although absolute rates of both cognitive decline and dementia were low).
