Dementia

A new study spanning 14 years suggests that optimism could be a powerful tool for healthy aging. Researchers found that older adults with a more positive outlook on life have a 15% lower risk of developing dementia.

A new study explores the complex link between high-fat diets and Alzheimer's risk. Researchers found dietary fat is associated with faster brain atrophy in healthy older adults, but a slower rate of decline in those with mild cognitive impairment.

Anxious and easily stressed individuals face an elevated risk of developing dementia. New research suggests a biological reason behind this link: highly neurotic people tend to have fewer protective omega-3 fatty acids running through their bloodstream.

Severe infections can trigger widespread inflammation that damages the aging brain. Now, a wave of large-scale studies suggests that routine adult vaccinations could act as a protective shield, lowering the risk of dementia and Alzheimer's disease.

Scientists have discovered that an experimental copper drug can unclog the brain's natural waste removal pumps. In a recent study, the treatment successfully cleared toxic Alzheimer's proteins and significantly improved spatial memory in mice.

A new study suggests that older adults who receive the recombinant shingles vaccine have a significantly lower risk of developing dementia. The findings point to a surprising brain-health benefit for a routine immunization.

As cannabis use grows among older adults, so do concerns about memory loss. However, a new study found that prior or occasional cannabis use is not associated with faster cognitive decline or a higher risk of dementia.

As we age, our ability to temporarily hold and process information tends to decline. However, a recent study of over 30,000 adults suggests that having more physical tissue in six specific brain regions predicts better working memory.

A small pilot study indicates that older adults with Alzheimer’s disease can safely take daily doses of creatine to boost brain energy levels. Patients taking the inexpensive supplement also experienced improvements in problem-solving and working memory tests.

A small clinical trial found that older adults who consumed bread enriched with a specific strain of maitake mushroom showed improved memory scores. The cognitive boost appears linked to the activation of immune-regulating natural killer cells.

New research reveals that chronic alcohol consumption rewires a key decision-making brain circuit in opposite ways, depending on whether the brain is burdened by Alzheimer's-related amyloid plaques or tau tangles.

A botanical extract derived from American ginseng can boost the brain's cellular waste disposal system, protecting synapses from age-related damage. In a recent rat study, the supplement successfully reversed cognitive decline and improved learning and memory.

Researchers used advanced computer models to show how 6PPD-quinone, a common pollutant from wearing tires, binds to proteins in the brain. The findings provide evidence that everyday traffic pollution might play a role in Alzheimer’s disease.

A shifting gut microbiome in aging mice creates localized inflammation that numbs the vagus nerve. Without regular sensory signals from the body, the brain struggles to encode new memories, revealing a surprising peripheral pathway for age-related cognitive decline.

While massive public awareness campaigns reach millions, they rarely inspire real lifestyle changes. A new review reveals that personalized, community-driven educational programs are far more effective at helping people adopt habits that reduce their dementia risk.
