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.

High-dose flu shots inked to lower Alzheimer's dementia risk in older adults

A large US claims-based study found that adults aged 65 and older who received a high-dose flu vaccine had a lower observed risk of Alzheimer dementia than those who received a standard-dose vaccine, with the association lasting up to 25 months in per-protocol analyses and 28 months in intention-to-treat analyses. The signal appeared stronger and more sustained in women, though the authors stress that the findings are observational and need confirmation in longer prospective studies.
