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.

Alzheimer’s Disease | Definition, Causes, Diagnosis & Treatment

Alzheimer’s Disease (AD) is the most common form of dementia worldwide (60-70% of all dementia cases) and is a progressive neurodegenerative disorder.

New blood protein biomarkers estimate timing of ALS symptoms

Months to several years before amyotrophic lateral sclerosis (ALS) symptoms arise, levels of certain blood proteins may dramatically shift.

AI mental health chatbots feel empathetic, but safety evidence still lags

Immune dysregulation may contribute to depression, schizophrenia, bipolar disorder, and anxiety through chronic inflammation, altered neuroimmune signaling, genetic susceptibility, and stress-related epigenetic changes. Evidence also suggests that biologically defined patient subgroups may benefit from more precise, immune-informed approaches to diagnosis and treatment.

YouTube’s health content rewards attention-grabbing videos over reliable medical information

Researchers analyzed 3,958 Korean-language medical YouTube videos and found that clickbait-heavy content attracted more views, likes, and comments. Higher-quality videos from medical professionals and public institutions often received less attention, highlighting a visibility gap in online health information.

Time-restricted eating may help lower dementia risk in older women

Results from a small clinical trial suggest it may be possible to reduce your risk of dementia by eating during fewer hours of the day.

Persistent financial hardship accelerates age-related cognitive decline

Persistent financial hardship accelerates age-related cognitive decline, according to a new study led by University College London (UCL) researchers.

Endotrophin may reveal metabolic risks linked to changing body fat

Researchers have identified a biological marker that rises and falls as body fat changes, offering new insight into how weight gain and weight loss may influence metabolic health.

Longer activity bouts link to lower future dementia and mental health risks

A UK Biobank analysis of 66,483 adults found that longer daily moderate-to-vigorous activity bouts and less fragmented activity were associated with lower subsequent risks of inpatient diagnoses of dementia, depression, and anxiety, independent of total activity time. In neuroimaging data from 13,108 participants, these activity patterns were also associated with more favorable brain measures, although the observational analyses cannot establish cause and effect.

Researchers link genome folding to gene activity and brain tissue organization in Alzheimer's

Researchers from Carnegie Mellon University's School of Computer Science, the University of Pittsburgh School of Medicine and the University of Washington shed new light on Alzheimer's disease that could point to new directions for treatment.

SuperAgers retain exceptional memory through mechanisms beyond genetics

Many people assume that some memory decline is an inevitable consequence of getting older. But a select group of older adults, known as SuperAgers, reach their 80s and 90s while retaining memory performance as good as or better than people in their 50s and 60s.

Frequent TV watching links to higher white matter lesion volume

ARIC researchers linked self-reported TV watching and occupational sitting in midlife with brain MRI measures obtained roughly 24 years later in 1,712 adults without dementia. Frequent TV watching was associated with greater white matter hyperintensity volume and lower volumes in several brain regions, while sitting at work was associated with lower white matter hyperintensity volume and larger selected cortical volumes.

UWM neuroscientist explores how estrogens regulate memory and brain function

Karyn Frick likes to think big. In college, she spent the summer after her junior year studying the neurobiology of memory in a lab at Johns Hopkins University. For hours at a time, Frick would watch rats scurry through mazes, entranced by their behavior.

Low-dose lithium may protect brain networks in early Alzheimer’s disease

This perspective examines whether restoring physiological lithium levels could help protect cognition in early Alzheimer’s disease. It proposes that lithium may support cholinergic signaling and brain connectivity, but emphasizes that rigorous, safety-monitored clinical trials are needed.

Dementia addiction and psychiatric disorders show distinct patterns of accelerated brain aging

People with dementia, mild cognitive impairment, alcohol addiction, or psychiatric disorders such as schizophrenia show increased brain aging, each in specific patterns within the brain, according to a study published July 21st in the open access journal PLOS Medicine by Shile Qi from the Nanjing University of Aeronautics and Astronautics, China, and colleagues.

Thymus hormone identified as key player in reversing age-related inflammation

Chronic, low-grade inflammation in the body-a phenomenon known as "inflammaging" because it increases with age-has been linked to many of today's leading causes of illness and death, including cancer, heart disease, metabolic conditions and neurodegenerative diseases.

Tau buildup in progressive supranuclear palsy alters brain networks linked to thinking and behavior

Researchers at Japan's National Institutes for Quantum Science and Technology (QST) have found that tau buildup in progressive supranuclear palsy (PSP) may affect brain networks involved in thinking and behavior.

SORLA protein may protect the brain from toxic tau tangles

Alzheimer's disease and many other forms of neurodegeneration share a common culprit. In these diseases, tau proteins that normally stabilize neuronal microtubule filaments within our nervous system networks instead form noxious knots and gradually disrupt the circuits they would otherwise preserve.
