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.

Good sleep protects brain health in people with cardiometabolic disease

People with type 2 diabetes, heart disease or stroke who sleep well have better cognitive function and greater brain volume than people with the same conditions who sleep poorly, according to a new study from Karolinska Institutet.

Genetic family mapping uncovers hidden links across ALS and FTD

Researchers at the Macquarie University Brain Institute and Clinic have helped accelerate the search for disease-causing genes by building new genetic 'families'.

Memory problems may matter more than slower thinking for dementia risk in frail adults

In a study of 7,023 adults in England, researchers identified three cognitive frailty profiles with different patterns of memory, executive function, and processing speed impairment. Over approximately 10 years, profiles involving memory impairment were associated with higher odds of subsequent dementia, while socioeconomic, educational, and psychosocial factors showed different associations across the three groups.

Heart disease and depression may affect brain aging in an unexpected way

A longitudinal study of 5,423 adults in England found that cardiovascular disease was associated with faster cognitive decline, with the strongest association observed among participants with consistently low depressive symptoms. Those with persistent moderate or high depressive symptoms generally experienced poorer cognitive performance and faster overall deterioration, despite showing a weaker additional association between cardiovascular disease and cognitive decline.

Private equity hospice buyouts drive up Medicare spending

A study of for-profit hospices acquired by private equity firms found that Medicare spending rose by 5.9 percent per hospice stay after acquisition, compared with similar for-profit hospices that weren't acquired.

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.
