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.

Chemists develop blueprint for designing powerful fluorescent materials for better disease detection

Chemists at the University of Bath have discovered how tiny molecular changes can transform the color and brightness of fluorescent probes based on the blue molecule azulene, paving the way for more powerful imaging tools for detecting diseases such as Alzheimer's, Parkinson’s and cancer.

People who walk more each day tend to score better on several brain tests

Researchers analyzed 14 years of physical activity and blood pressure records from 3,093 US adults and found that higher daily step counts were associated with better performance on tests of attention, cognitive control, and reward-related decision-making. Higher systolic blood pressure was associated with poorer delay-discounting performance, but accounted for only 4.8% of its association with physical activity, while the single cognitive assessment prevented conclusions about causation or cognitive decline.

Nature-based activities may offer lasting relief from loneliness

About one in three Americans and one in six people worldwide feel lonely on a regular basis, a troubling reality that has prompted some public health officials to declare an "epidemic of loneliness."

$5.8 million study explores gut-brain inflammation in people with HIV

Oregon Health & Science University researchers have secured a $5.8 million, five-year federal award to investigate whether damage to the gastrointestinal tract contributes to neuroinflammation in people living with HIV - raising the potential for new treatments to preserve brain function in people with HIV and older adults.

Women with polyendocrine metabolic ovarian syndrome more likely to have Alzheimer's and dementia

Alzheimer's disease and dementia may be more common in women with polyendocrine metabolic ovarian syndrome (PMOS), formerly known as polycystic ovary syndrome (PCOS), according to a review of existing evidence published in the Journal of the Endocrine Society.

Scientists pinpoint key hotspot driving tau propagation in dementia

Diseases such as Alzheimer's and frontotemporal dementia are considered neurodegenerative tauopathies, in which tau proteins in the brain misfold and lead to cognitive decline.

Buck Institute and Georgetown lead effort mapping harmful protein changes before disease begins

A research "super team" co-led by theBuck Institute for Research on Aging and Georgetown University has received an award of up to $51.7 million from the Advanced Research Projects Agency for Health (ARPA-H) to predict how disease-causing proteins misfold before irreversible damage occurs and use those predictions to develop novel diagnostics and treatments.

16-year study links worsening vision to higher dementia risk

Researchers followed 15,576 older adults in Hong Kong for up to 16 years and linked moderate to severe visual impairment to higher dementia risk, with rapid visual decline strengthening the association at poorer levels of vision. They estimated that severe impairment corresponded to 2.1 fewer dementia-free years over the study period, but could not establish that correcting vision prevents dementia.

A study links a blood protein to memory and brain changes in Down syndrome

Researchers studying 88 adults with Down syndrome and 43 controls estimated that serum β-synuclein increased approximately two decades before expected Alzheimer’s symptoms, preceding changes in other blood biomarkers. Higher levels correlated with poorer memory and brain changes, but the cross-sectional study could not distinguish whether the earliest increase reflected Alzheimer’s-related synaptic dysfunction, trisomy 21-related neurobiology, or both.
