Alzheimer's Disease

By genetically enhancing a specific protein in mice, scientists successfully reduced the toxic tau tangles associated with Alzheimer’s disease. The study offers new insights into how the brain defends itself against severe neurodegenerative damage.

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 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.

Scientists have discovered an important link between sleep, genetics, and Alzheimer’s disease. New findings suggest that getting poor sleep can accelerate brain shrinkage and memory loss in older adults carrying specific genetic variants.

A high-fat diet and early pesticide exposure affect learning and memory in radically different ways depending on an animal's biological sex and genetic makeup. The findings suggest dietary advice for brain health should be tailored to individual profiles.

Glucosamine is a popular arthritis remedy, but it may be dangerous for those with early memory loss. New research indicates this sugar molecule disrupts brain chemistry, accelerating both Alzheimer's disease progression and mortality rates.

Many patients with Alzheimer’s disease lose their sense of smell before experiencing memory loss. New research reveals how poor communication between specific brain regions causes this sensory decline, offering insights that could lead to earlier diagnostic tests.
