Listening to Music After 70 May Cut Dementia Risk by Nearly 40%

Older adults who regularly listen to or play music may significantly lower their risk of dementia, according to a study of more than 10,800 people over age 70. Those who always listened to music showed a 39% lower risk of developing dementia and better memory performance, while those who played instruments had a 35% lower risk.

Gene Editing Reverses Age-Related Memory Loss

Researchers have identified molecular mechanisms behind age-related memory decline — and shown they can be reversed. Two studies revealed that correcting specific molecular processes in the hippocampus and amygdala, and reactivating a silenced memory-supporting gene called IGF2, improved memory in older rats.

Poor Oral Health Linked to Brain Damage Markers

A new study finds that older adults with gum disease are more likely to show signs of white matter damage in the brain — a change tied to memory decline, balance issues, and higher stroke risk. MRI scans revealed that participants with gum disease had significantly more white matter hyperintensities than those without, even after accounting for age and other health factors.

Older Adults See Ambiguous Faces as Happier

A new study reveals that older adults are more likely than younger people to interpret ambiguous facial expressions as happy rather than angry. Using brain imaging, researchers found that this positivity bias is linked to increased activity in the locus coeruleus — the brain’s tiny “blue spot” that regulates alertness and stress — and its connection to the dorsolateral prefrontal cortex.

Brain’s Shape Could Reveal the Earliest Signs of Alzheimer’s

A groundbreaking study reveals that aging alters not just the size but the shape of the human brain, reshaping regions in ways linked to memory and reasoning decline. Researchers found that as people age, the lower and front areas of the brain expand outward, while the upper and back regions compress inward.

Head Injuries in Adults Linked to Dementia

A large-scale Canadian study has found that older adults who sustain traumatic brain injuries (TBI) face a significantly higher risk of developing dementia, needing home care, or being admitted to long-term care. Researchers found that TBIs, most commonly caused by falls, increase dementia risk by up to 69% in the first five years following injury.

How the Brain’s GPS System Falters With Age

Spatial memory — the ability to recall “where” — is one of the first cognitive skills to decline in aging and a hallmark of dementia. Researchers found that in older mice, grid cells in the medial entorhinal cortex, which act like the brain’s GPS, became unstable and less precise.

Dietary RNA Molecules May Hold the Key to Slowing Cellular Aging

Living longer doesn’t always mean living healthier, and researchers are exploring how diet can extend healthspan. A study in worms shows that specific dietary RNA molecules protect cells from harmful protein build-up, a major driver of aging and age-related disease.

Lifelong Social Bonds Can Slow Biological Aging at the Cellular Level

A new study shows that lifelong social advantages—from early parental warmth to adult friendships and community support—can slow biological aging. Researchers analyzed over 2,100 participants and found that those with stronger, more consistent social connections had younger biological ages according to epigenetic clocks GrimAge and DunedinPACE.

Lifestyle Changes Show Power to Prevent Alzheimer’s

A growing body of research underscores that Alzheimer’s and cognitive decline are not inevitable parts of aging. Lifestyle interventions targeting exercise, diet, social engagement, and cognitive stimulation have been shown in large clinical trials to improve brain function and slow decline.

Attention and Focus Abilities Peak Between Ages 27 and 36

Researchers analyzed 139 neuroimaging studies spanning ages 5 to 85 to map the brain’s activity in cognitive control. They found an inverted U-shaped lifespan trajectory, with brain activity rising through adolescence, peaking between ages 27 and 36, and then gradually declining.

The Midlife “Unhappiness Hump” Has Vanished, But at a Cost

A new large-scale study finds that the long-observed “unhappiness hump,” where mental distress peaked in midlife, has disappeared. Instead, younger people now report the highest levels of anxiety, depression, and stress, with ill-being declining across the lifespan.
