Aging

A study has looked at six key healthy lifestyle factors that can significantly reduce memory loss in old age, finding adults engaging in between four and six healthy behaviors could significantly reduce their risk of developing dementia.

Researchers studying healthy centenarians have homed in on a gene mutation that plays a crucial role in maintaining cardiovascular health in old age. Across a series of experiments the researchers demonstrated how gene therapy could rejuvenate aging hearts.

New research has found HRT can be linked with better brain health and cognition among women with a genetic risk of developing Alzheimer's. The findings build on research trying to understand why women are more likely to develop Alzheimer's compared to men.

Harvard scientists have investigated why we age, and how we could stop it. In tests in mice, the team showed that epigenetic “software glitches” drive the symptoms of aging – and a system reboot can reverse them, potentially extending lifespan.

Just six minutes of intense aerobic exercise a day could be one of the most effective ways to keep you brain healthy into old age. New research has found brief bursts of exercise increase levels of a brain protein known to optimize cognitive health.

New research shows early retirement can be linked to an acceleration of age-related cognitive decline. Looking at data from a pension program in China, the findings suggest increased social activity may mitigate the cognitive costs of early retirement.

A fascinating study from researchers at the National Institutes of Health suggests people who don't drink enough fluids could be at greater risk of chronic disease and are more likely to die at a younger age.

A study looking at post-mortem brain tissue samples has found severe COVID-19 is associated with molecular signs of brain aging. The researchers warn potential long-term neurological problems could emerge in the years following the pandemic.

The failure of another massive Phase 3 trial testing an anti-amyloid dementia treatment marks a new twist in the ongoing rollercoaster of research looking for drugs to reduce build-up of the protein commonly thought to be the key cause of Alzheimer's.

Researchers have discovered a unique fat molecule in the brain may have anti-inflammatory effects. Animal studies found levels of the molecule decline with age and their absence could contribute to inflammation associated with neurodegeneration.

New results from a clinical trial lasting over a year have shown playing crossword puzzles may be more effective at slowing age-related cognitive decline than modern video games specifically developed to improve memory.

New research on aging in roundworms has thrown up some intriguing results, with scientists at Nanyang Technological University (NTU), Singapore finding they could increase the animals lifespan by feeding them a high-sugar diet.
