Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

Alzheimer’s Disease | Definition, Causes, Diagnosis & Treatment

Alzheimer’s Disease (AD) is the most common form of dementia worldwide (60-70% of all dementia cases) and is a progressive neurodegenerative disorder.

Better heart health slows brain aging and lowers dementia risk, study finds

A JAMA Network Open study finds that better cardiovascular health (CVH) in older adults is linked to lower levels of neurodegenerative biomarkers, particularly neurofilament light chain (NfL). These benefits are consistent across races and especially impactful for individuals carrying Alzheimer's-related genetic risks.
