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.

Gut microbial catalog reveals systemic inflammation drivers in spinal injury

Scientists exploring the links between a spinal cord injury, inflammation and immune function have turned their attention to a genome-level analysis of the gut microbial community, with early study results offering hints at potential new approaches to aid healing.

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.

Plasma proteins offer clues to biological aging and mortality risk

A new study published in Geromedicine has identified 17 plasma proteins associated with all-cause mortality in older adults and found that several of these proteins also track with measures of biological aging across multiple organ systems.
