Aging-related changes in a class of immune cell known as group 2 innate lymphoid cells (ILC2s) could allow doctors to combat the effects of aging on the brain, researchers at Albany Medical College in New York have found. Their study suggests that targeting these cells might reduce age-related cognitive decline and combat aging-associated neurodegenerative disease… Read more

Having a larger hippocampus doesn’t always reliably predict learning and memory abilities in older adults, research suggests. It’s normal for the hippocampus — a curved, seahorse-shaped structure embedded deep in the brain — to shrink as we age, but it’s much more pronounced in people with mild cognitive impairment or Alzheimer’s disease. Scientists long believed… Read more

Racism may result in tolls related to premature biological aging among African Americans, indicates a study led by Auburn University. African Americans who reported more racial discrimination over a 10-year period showed signs of faster aging at the cellular level during the same time frame. “One of the factors that can lead to more rapid… Read more

Not getting enough water is enough to make you feel sluggish and give you a headache, but a new study[1] suggests for older women, too little hydration may also relate to cognitive performance. Researchers investigated whether hydration levels and water intake among older adults related to their scores on several tests designed to measure cognitive… Read more
