Dementia

A study of dolphins stranded in Florida suggests that repeated exposure to algal toxins may trigger brain changes associated with Alzheimer’s disease.

Researchers have identified a link between higher abdominal fat and lower cognitive scores in postmenopausal women, suggesting a new tie between metabolic and brain health.

An individual's genetic tendency for elevated levels of a key protein in the blood signal a heightened risk for developing Alzheimer's disease, according to new research.

A strong sense of purpose is linked to a lower risk of developing cognitive impairment. This protective effect was present even in individuals with a high genetic risk for dementia.

A new study offers a surprising look at the link between physical activity and the proteins that build up in the brains of people with Alzheimer's disease.

New research suggests feline dementia mirrors human dementia in several key ways.

Women are more often diagnosed with Alzheimer’s disease, but why? New research challenges a common assumption about brain aging, pointing scientists toward other potential explanations for this well-known disparity.

A novel treatment for Alzheimer's doesn't attack brain plaques directly. Instead, it repairs a critical protective barrier, leading to remarkable recovery in animal models and offering a new direction for future therapies.

A massive study found that while education is linked to better memory and larger brains, it does not slow the rate of cognitive decline. The advantage is a lifelong head start, not a shield against the aging process.

For adults over 70, musical activities may help protect against dementia. New research indicates that frequent music listeners and instrument players had up to a 39 percent lower risk of developing the condition over the study period.

A new study of over 27,000 adults reveals a direct link between poor sleep and accelerated brain aging. Researchers found those with unhealthy sleep habits had brains that appeared structurally older on MRI scans than their chronological age.

A new study reveals a powerful link between a person's neighborhood and their biological risk for dementia. Researchers found that social and environmental hardships correspond with physical changes in brain structure and blood flow.

New research published in Nature Communications provides evidence that aging changes the brain’s shape in predictable ways. These geometric shifts may influence memory and thinking, offering potential clues into the early structural signs of cognitive decline and dementia risk.

Inhaled CBD reduced inflammation and improved cognition in mice with Alzheimer’s, according to a study in eNeuro, pointing to a promising immune-based approach for treating the disease beyond traditional amyloid-focused therapies.

The air we breathe may be seeding our brains with toxic proteins. A landmark study reveals a direct link between fine particulate pollution and the harmful protein buildup seen in Lewy body dementia, a common neurodegenerative disease.
