Distinct tau chemical signatures redefine diagnosis across neurodegenerative diseases

Tau protein aggregation is a shared feature in over 20 neurodegenerative diseases (collectively referred to as "tauopathies"). New research led by Boston Children's Hospital challenges the current "one-size-fits-all" approach to diagnosing and treating these tauopathies.

Research uncovers why certain brain cells are more resilient to tau protein buildup

New research by UCLA Health and UC San Francisco has uncovered why certain brain cells are more resilient than others to the buildup of a toxic protein that is a hallmark of Alzheimer's disease and related dementias, potentially leading to new targets for therapies or treatments.

Study uncovers how the brain's 'memory replay' process is impaired in Alzheimer's disease

Memory dysfunction in Alzheimer's disease may be linked to impairment in how the brain replays our recent experiences while we are resting, according to a new study in mice by University College London (UCL) scientists.

Smartwatch app to track social interactions of stroke survivors may help maximize recovery

A smartwatch app designed to measure social interactions of hospitalized stroke survivors may enable new treatments to preserve or enhance cognition, social engagement and quality of life after a stroke, according to a preliminary study to be presented at the American Stroke Association's International Stroke Conference 2026.
