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.

Managing misfolded proteins to prevent Parkinson’s disease

The protein alpha-synuclein is abundant in healthy brains and plays an important role in enabling communication between nerve cells. However, under certain conditions, misfolded alpha-synuclein proteins can accumulate into toxic clumps inside neurons

Social media and AI chatbots face gaps in supporting vulnerable users

Two new studies highlight how communication gaps can complicate efforts to protect vulnerable users of technologies such as social media and AI chatbots. Researchers will present the work at the 29th ACM Conference on Computer-Supported Cooperative Work and Social Computing (CSCW 2026), held October 1–14 in Salt Lake City.

Swedish study links lower midlife cognitive scores to future strokes

Adults in their 60s who scored lower on tests of overall thinking ability, memory and how quickly they processed information were more likely to have a stroke years later, according to new research conducted in Sweden, published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.

What older adults do on screens may matter more than total screen time

Across 8,996 older adults in four cohorts, television viewing was associated with poorer global cognition, while computer use was associated with better cognitive performance, with the strongest positive associations at low-to-moderate levels of use. Mendelian randomization supported these opposing patterns and linked genetically predicted television viewing time to lower left insula volume, which accounted for an estimated 14.8% of its association with poorer cognitive performance.

Could the Mediterranean diet protect the brain through the gut?

A narrative review finds that the Mediterranean diet may support brain health through gut microbiome, immune, metabolic, and barrier-related pathways, but direct human evidence that microbiome remodeling mediates neuroprotection remains limited. The proposed mechanisms involve microbial metabolites, reduced inflammatory signaling, stronger intestinal and blood-brain barrier function, and possible effects on processes linked to Alzheimer’s and Parkinson’s diseases.
