- Higher dementia risk in women with prolonged fertility September 17, 2020Women with a longer reproductive period had an elevated risk for dementia in old age, compared with those who were fertile for a shorter period, a population-based study.
- Older people with early, asymptomatic Alzheimer's at risk of falls September 15, 2020Older people without cognitive problems who experience a fall may have undetected neurodegeneration in their brains that puts them at high risk of developing Alzheimer's dementia, according to a new study.
- Risk gene for Alzheimer's has early effects on the brain September 15, 2020A genetic predisposition to late-onset Alzheimer's disease affects how the brains of young adults cope with certain memory tasks. Researchers find are based on studies with magnetic resonance imaging in individuals at the age of about 20 years. The scientists suspect that the observed effects could be related to very early disease processes.
- Telomere length varies across human tissue types September 10, 2020A new study answers the question of whether or not blood cell telomere length is a suitable proxy for telomere length in other tissues by examining over 20 human tissue types, finding variations and correlations between different tissue types.
- Concussion discovery reveals dire, unknown effect of even mild brain injuries September 10, 2020Even mild concussions cause severe and long-lasting impairments in the brain's ability to clean itself, and this may seed it for Alzheimer's, dementia and other neurodegenerative problems.
- Gestational diabetes may accelerate child's biological age September 10, 2020Children born to mothers who had diabetes during pregnancy may age faster biologically and be at an increased risk for obesity and high blood pressure, according to researchers.
- Scientists decipher role of a stress response gene September 9, 2020A team of scientists is shedding new light on the gene regulatory pathways activated by cortisol, a hormone secreted in response to stress. Their research helps explain why exposure to chronic stress early in life shortens lifespan and contribute to age-related chronic diseases later in life -- long after the source of stress has been […]
- Lumpy proteins stiffen blood vessels of the brain September 9, 2020Deposits of a protein called 'Medin', which manifest in virtually all older adults, reduce the elasticity of blood vessels during aging and hence may be a risk factor for vascular dementia.
- Muscle aging: Stronger for longer September 9, 2020With life expectancy increasing, age-related diseases are also on the rise, including sarcopenia, the loss of muscle mass due to aging. Researchers have demonstrated that a well-known drug can delay the progression of age-related muscle weakness.
- Older women with type 2 diabetes have different patterns of blood use in their brains September 8, 2020A researcher is reporting that the brains of older women with Type 2 diabetes do not use as much oxygenated blood as those who don't have the disease. The research is the first to point to changes in blood use in the brain as the primary reason for diabetes-related deficits in motor function.
