Lithium Fails to Slow Cognitive Decline in Alzheimer’s

A new meta-analysis of six randomized controlled trials shows that lithium supplementation does not significantly slow cognitive decline in people with mild cognitive impairment or Alzheimer’s disease. While preclinical evidence suggests lithium supports resilience against amyloid and tau pathology, these benefits failed to translate to clinical outcomes using traditional lithium salts.

Low Income, Vision Loss, and Isolation Drive Dementia Risk

A new study reveals that people with lower incomes and those from historically underrepresented racial and ethnic groups carry a higher burden of modifiable dementia risk factors. Vision loss and social isolation were among the most significant contributors for those living below the poverty line, suggesting that better access to healthcare and community support could have major protective effects.

Speaking Multiple Languages May Slow Down Biological Aging

A large-scale study of more than 86,000 Europeans found that speaking multiple languages may help slow biological and cognitive aging. Using artificial intelligence to assess “biobehavioral age gaps,” researchers discovered that multilingual individuals were over twice as likely to show signs of healthy aging compared to monolinguals.

Stress Undermines Brain Circulation, Increases Dementia Risk

Researchers found that a rare class of neurons—type-one nNOS neurons—plays a central role in regulating brain blood flow and coordinating neural activity in mice. Removing these stress-vulnerable cells caused major drops in vessel oscillations and widespread reductions in electrical signaling, suggesting a crucial link between neuron loss, blood-flow decline, and brain-function impairment.

Your Neighborhood Could Influence Your Risk of Dementia

Researchers found that living in a socioeconomically deprived neighborhood can harm brain health as early as midlife. People from these areas showed more signs of small-vessel brain damage, slower thinking skills, and poorer control of lifestyle factors such as blood pressure, obesity, and sleep.

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.
