          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.

          New AI Tool Reveals Genetic Link Between Memory Cells and Alzheimer’s

          A new computational tool developed by researchers has uncovered genetic evidence directly linking Alzheimer’s disease to the loss of memory-making neurons, helping to resolve a decades-long mystery in dementia research. The algorithm, called seismic, matches genetic data to individual cell types, outperforming previous methods and highlighting how specific brain cells—not just immune cells—are implicated in Alzheimer’s.

          Where You Live Could Shape Your Brain and Dementia Risk

          New research shows that neighborhood conditions — from pollution and housing to economic opportunity — may directly affect brain health and dementia risk. Analyzing brain scans and biomarkers from 679 adults, scientists found that people living in areas with higher social and environmental disadvantages showed signs of reduced brain thickness, altered blood flow, and white matter changes.

          Lifelong Social Bonds Keep the Aging Brain Sharp and Flexible

          Rats that lived in social groups throughout their lives retained youthful memory and mental flexibility well into old age, according to new research. Even with equal physical stimulation, only socially connected rats performed as well as younger ones on complex memory tests, while isolated rats showed significant decline.

          Calcium Supplements Do Not Raise Dementia Risk

          A long-term study of more than 1,400 older women found no evidence that calcium supplements increase dementia risk, easing previous concerns about their safety. Conducted over 14.5 years, the research compared women taking calcium monotherapy to those given a placebo and found no difference in cognitive outcomes.

          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.

          CBD Calms the Inflamed Alzheimer’s Brain

          A new study reveals that cannabidiol (CBD) can significantly reduce neuroinflammation associated with Alzheimer’s disease. In experiments using an Alzheimer’s mouse model, researchers found that inhaled CBD lowered the activity of key genes driving inflammation and decreased harmful proinflammatory molecules in the brain.

          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.

          Sleep Disorders Predict Parkinson’s or Dementia Years Ahead

          Two landmark international studies show that brain biomarkers can predict whether people with REM sleep behaviour disorder (iRBD) will develop Parkinson’s disease or dementia with Lewy bodies (DLB). MRI scans revealed that reduced glymphatic system function signals higher risk for Parkinson’s, while increased free water in the basal nucleus of Meynert predicts progression to DLB.

          A large international study shows that the accumulation of social hardships across life—known as the social exposome—has lasting effects on the brain. Adverse exposures, including low education, food insecurity, and limited healthcare, were linked to cognitive decline, mental health issues, and altered brain structure and function.

          Artificial Sweeteners Tied to Faster Cognitive Decline

          A large study of nearly 13,000 adults found that consuming high levels of certain artificial sweeteners is linked to faster declines in memory and thinking over eight years. The effect was particularly strong in people with diabetes and those under 60. Some sweeteners, like aspartame and saccharin, were strongly associated with decline, while tagatose was not.
