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.

GLP-1 Receptor Agonists in Alzheimer’s Disease: Emerging Off-Label Neuroprotective Potential

GLP-1 receptor agonists show strong preclinical neuroprotective potential in Alzheimer’s disease through effects on insulin signaling, neuroinflammation, amyloid, tau, and brain metabolism. Human evidence remains mixed, with observational studies suggesting lower dementia risk but randomized trials yet to demonstrate a clinically meaningful disease-modifying benefit.

Latest Alzheimer's & Dementia News and Research

New dementia risk tool designed for the countries that need it most

An international team led by Northumbria University has developed and validated a simple five-factor risk score to identify older people at elevated risk of dementia in low- and middle-income countries (LMICs) - where around 60% of the world's dementia cases now occur.

Study identifies molecular links between menopause and brain aging

Researchers at UC Santa Barbara, UC San Francisco and international collaborators are uncovering the cascade of molecular events that happen when women undergo menopause, a time of life marked by endocrine changes and symptoms like hot flashes, brain fog and sleep disturbances.

Long-term study supports cardiovascular safety of contemporary hormone replacement therapy

Contemporary hormone replacement therapy (HRT) was not associated with an increased risk for heart attack, stroke, blood clots or death among women ages 45 to 59, according to a large, long-term study of over 52,000 women in Israel.

Scientists may have underestimated how much genes contribute to Alzheimer's risk

A large multi-ancestry genetic analysis identified 127 genomic loci associated with Alzheimer's disease, including 48 previously unreported loci, and implicated microglial and neuronal gene-expression patterns in disease susceptibility. The researchers estimated that common genetic variants account for 16% of Alzheimer's disease liability in European-ancestry populations, substantially higher than previous estimates, while demonstrating improved polygenic risk prediction that remained less reliable in non-European populations.

Multivitamins boost key vitamin levels, but do they improve your health?

A scoping review of 157 clinical trial reports found that multivitamins consistently improved circulating levels of folate, vitamin B6, and vitamin B12, while other nutritional and clinical effects varied by formulation, population, and baseline nutritional status. Selected prenatal and cognitive outcomes improved in some trials, but evidence for cardiovascular disease prevention was largely negative, and the review could not establish the overall certainty of clinical benefits.

Limited app use adds a twist to a nurse-led dementia risk trial

A cluster-randomized trial involving 403 Australian adults aged 45–65 found that a 12-month nurse-led behavioral intervention supported by a mobile app modestly improved estimated dementia risk scores compared with brief counseling and usual care. The study found no significant improvements in cognitive performance or other secondary outcomes, leaving its long-term effects on dementia prevention uncertain.
