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.

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.

Better blood pressure control could prevent over 518,000 annual deaths worldwide

Effective management of high blood pressure could prevent more than 518,000 annual deaths from cardiovascular disease around the world, according to preliminary research presented at the American Heart Association's Hypertension Scientific Sessions 2026.

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.

Routine blood test may offer clues to future dementia risk

A common blood test already carried out during routine health checks may contain clues about a person's long-term risk of dementia, according to research being presented at the ECNP Congress in Munich and recently published in the Journal of Alzheimer's Disease.

Sutter Health care model safely expands local Alzheimer's treatment

A multidisciplinary care model developed across Sutter Health helped general neurologists address a practical challenge facing health systems nationwide: how to safely offer newer Alzheimer's disease treatments in community settings to more patients.

Adults with ADHD face higher risk of developing dementia later in life

A new study led by University of Pittsburgh School of Medicine researchers finds that adults with attention-deficit/hyperactivity disorder (ADHD) face a significantly higher risk of developing dementia or mild cognitive impairment later in life.

Dementia status influences end-of-life care decisions despite advance directives

People were about 19 percentage points less likely to recommend life-sustaining treatment for a seriously ill patient with dementia than for a patient without dementia, even when an advance directive requested life-sustaining care, according to new research from the University of Colorado Anschutz.
