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.

UCSF launches global study tracking real-world psychedelic experiences

Most psychedelic experiences don't happen in research labs. To better understand their effects, UC San Francisco scientists are going where the experiences are and launching a global study to track what psychedelics do to people's brains, bodies and well-being.

$32 million grant extends landmark Alzheimer's research through 2031

When Leonard Berg, MD, then a neurologist at Washington University School of Medicine in St. Louis, noticed memory problems among his older patients in the 1970s, he refused to dismiss the problems as part of "normal aging" or senility but instead set out to understand what was happening in their brains.

Scientists scanned people's brains before and after 45 days of yoga. Here's what changed

In a randomized controlled trial involving 139 healthy adults, 45 days of a standardized yoga program improved mood, self-reported sleep quality, and selected short-term memory measures compared with a waitlist control group. Brain scans from 43 participants also revealed changes in functional connectivity across networks involved in movement, attention, language, and cognitive processing, although the long-term significance remains uncertain

Could eating more mushrooms help protect your brain as you age?

A review of existing research suggests that ergothioneine, a natural antioxidant found primarily in mushrooms, may protect brain cells against oxidative stress, inflammation, and damage associated with Alzheimer's and Parkinson's diseases. Although laboratory and animal studies show promising neuroprotective effects, human evidence remains limited, and larger clinical trials are needed to determine whether supplementation can prevent or slow neurodegeneration.
