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.

Shingles and RSV vaccines with AS01 adjuvant reduce dementia risk

Researchers found that older adults who received AS01-adjuvanted shingles or RSV vaccines had a significantly lower risk of developing dementia within 18 months compared to flu vaccine recipients. The protective effect is likely linked to the AS01 adjuvant itself, highlighting new avenues for dementia prevention.

How 50,000 years of ancestry shaped India’s unique disease patterns

Scientists sequenced the genomes of 2,762 individuals across India, revealing the country’s unique ancestral makeup and a wealth of previously undocumented disease-related gene variants. The study highlights how ancient migrations, founder effects, and endogamy have shaped both diversity and disease risk in India.
