Alzheimer's Disease

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.

While many people with early signs of Alzheimer's disease remain mentally sharp for years, others experience rapid memory loss. Scientists have discovered distinct patterns of decline, which could change how future treatments are tested and developed.

A single snapshot of brain volume forecasts future memory decline better than tracking brain shrinkage over time. This approach highlights the brain's structural reserve, offering a practical tool to identify those at highest risk for developing clinical dementia.

Scientists discovered how some people maintain sharp minds despite having Alzheimer's-related brain damage. A recent study identifies a specific genetic signature and introduces a mouse model that recreates this protective state to guide future treatments.

By measuring how well healthy adults track their movements in virtual reality, scientists can estimate future thinning in specific brain regions. This approach could provide a simple, early warning system for neurodegenerative diseases.

Why do dementia and depression look so similar in older adults? New research maps the brain's chemistry to show how the two conditions share serotonin disruptions but diverge sharply in how they alter or destroy brain cells.

A new study suggests that participating in a mix of physical, social, and mental activities during middle age is linked to better cognitive performance, even for people with a high genetic risk for Alzheimer's disease.

A new study reveals that people born with genetic traits favoring physical strength experience less cognitive decline as they age. This underlying biological connection occurs independently of individual exercise habits or traditional markers of Alzheimer’s disease.

A lifetime of reading, playing games, and learning can lower your risk of Alzheimer's disease by 38 percent. According to a recent Neurology study, this lifelong mental enrichment builds a protective buffer against age-related cognitive decline.

New research published in The Journal of Nutrition shows a link between eating eggs and brain health. Scientists found that older adults who consume eggs moderately experience a noticeably lower risk of Alzheimer's disease.

A newly developed mathematical index allows standard MRI scans to detect hidden Alzheimer’s risks years before symptoms emerge, tracking the subtle impacts of genes and cardiovascular health on the brain to predict future memory decline.

New research shows that untreated sleep-disordered breathing alters the brain physically. These disruptions may make the brain more vulnerable to Alzheimer’s disease, fundamentally changing how toxic proteins build up across different stages of cognitive decline.

A recent study using advanced cell mapping shows that lithium chloride changes the activity of multiple enzymes linked to Alzheimer’s disease. These findings could help researchers design safer, more effective treatments for cognitive decline and dementia.

Standard cognitive tests can be flawed by cultural and educational biases. Researchers argue that monitoring a patient's ability to perform daily routines offers a more practical, culturally adaptable early warning system for dementia.
