Alzheimer's Disease

A new study reveals that two different inflammatory proteins in the blood signal separate types of brain damage. Both distinct pathways ultimately converge to fuel Alzheimer's-related tau tangles, brain shrinkage, and memory decline in older adults.

Professions requiring constant spatial navigation physically reshape the hippocampus, the brain region Alzheimer’s attacks first. By routinely building mental maps, individuals may develop a cognitive reserve that delays the onset of severe memory loss.

New research reveals that physical social isolation harms the aging brain independently of subjective feelings of loneliness. Simulated public health interventions show that reconnecting isolated older adults can directly protect against cognitive decline.

A 12-week program requiring older adults to read out loud, write by hand, and solve basic math problems for 30 minutes a day resulted in measurable improvements on cognitive tests.

People with Down syndrome face an elevated risk of developing Alzheimer's disease. A recent study indicates that simple blood tests can accurately detect early brain changes, paving the way for easier diagnosis and inclusive clinical trials.

A recent review in Molecular and Cellular Neuroscience suggests that popular weight-loss and diabetes drugs might help clear brain proteins associated with Alzheimer's disease. While animal studies show promise, human data remains limited.

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.
