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.

Tai chi improves memory and sleep in older adults with type 2 diabetes

A 12-week randomized trial found that remotely delivered Tai Chi significantly enhanced cognitive performance and sleep quality in older adults with Type 2 Diabetes. These gains surpassed those from supervised fitness walking or usual care, without increasing adverse events.

Repetitive head impacts trigger early brain changes in young athletes

Research supported by the National Institutes of Health (NIH) shows that repeated head impacts from contact sports can cause early and lasting changes in the brains of young- to middle-aged athletes.

High fat diet impairs memory formation through autophagy dysfunction

Modern lifestyles and dietary changes have significantly increased the consumption of high-fat foods, contributing to a steep rise in the prevalence of obesity, diabetes, and metabolic disorders.

Watching more than 4 hours of TV daily raises the risk of cognitive decline

This study finds a link between long TV viewing and cognitive impairment, stressing the importance of addressing sedentary lifestyles for dementia prevention.

Two-step blood and scan strategy delivers near-perfect accuracy for early Alzheimer's signs

Plasma p-tau217 testing can help detect preclinical Alzheimer disease in cognitively unimpaired adults. Using it as a first-line screen followed by positron emission tomography or cerebrospinal fluid testing boosts accuracy, reduces false positives, and streamlines recruitment.

AI breakthrough offers a new way to predict and visualize disease processes

To solve a problem, we have to see it clearly. Whether it's an infection by a novel virus or memory-stealing plaques forming in the brains of Alzheimer's patients, visualizing disease processes in the body is the first step toward alleviating human suffering. It's also often the most difficult and costly.

Age influences amyloid positivity in Parkinson's disease without dementia

A new research paper was published in Volume 17, Issue 8 of Aging-US on August 6, 2025, titled "Age-related trends in amyloid positivity in Parkinson's disease without dementia."

Lifestyle changes show promise in preventing cognitive decline and Alzheimer’s disease

An estimated 7.2 million Americans over age 65 currently live with Alzheimer's disease (AD). That number is expected to nearly double to 13.8 million by 2060.

Study uncovers how the brain flexibly switches communication routes

When we recall something familiar or explore a new situation, the brain does not always use the same communication routes.

Boosting PI31 to restore synaptic function and prevent neurodegeneration

One fundamental feature of neurodegenerative diseases is a breakdown in communication. Even before brain cells die, the delicate machinery that keeps neurons in touch-by clearing away protein waste at the synapses-starts to fail.

Researchers develop a digital cognitive test for diagnosing Alzheimer's disease

Researchers at Lund University in Sweden have developed a digital cognitive test for diagnosing Alzheimer's disease that is intended for use in primary care.

Researchers reveal why global gains against chronic diseases are stalling

Researchers analysed mortality data from 185 countries and found that while global non-communicable disease (NCD) deaths before age 80 declined from 2010 to 2019, progress slowed compared to 2001–2010. Gains were mainly from drops in heart disease and stroke, but rising burdens from diabetes, cancers, and neuropsychiatric conditions stalled momentum.

Novel vitamin K analogs show promise for reversing neurodegenerative diseases

Neurodegenerative diseases like Alzheimer's, Parkinson's, and Huntington's disease are characterized by the progressive loss of neurons.

Caregiver personas offer insights for improving dementia medication management

Understanding the strategies and unmet needs of caregivers managing medications for people with Alzheimer's disease or related dementias may improve the lives of both caregivers and patients.

Under Trump, FDA seeks to abandon expert reviews of new drugs

FDA leaders under President Donald Trump are moving to abandon a decades-old policy of asking outside experts to review drug applications, a move critics say would shield the agency's decisions from public scrutiny.

UCL launches landmark trial of Alzheimer’s blood test

A major UCL-led clinical trial, aiming to transform the diagnosis of Alzheimer's disease through a simple blood test, is now welcoming its first participants who will be recruited via memory clinics across the UK.

Object recognition shapes spatial awareness in the brain

We take our understanding of where we are for granted, until we lose it. When we get lost in nature or a new city, our eyes and brains kick into gear, seeking familiar objects that tell us where we are.

BU professor wins RF1 $3.2M grant for age-related neuropathology research

Tara Moore, PhD, professor of anatomy & neurobiology at Boston University Chobanian & Avedisian School of Medicine, has been awarded a five-year, RF1 $3.2M grant from the NIH's National Institute of Aging for her project "Extracellular vesicle treatment and age-related neuropathology in non-human primates."

Compact bNIRS technology could become a diagnostic toolkit for dementia

Early and accurate diagnosis of dementia remains a major challenge. Standard approaches such as MRI and PET scans can provide valuable information about brain structure and function, but they are expensive, not always accessible, and often too expensive for repeated use.

SLIT2 protein levels in the eye and blood linked to cognitive function

Neurocognitive impairments are classified by pathological changes with potential for destruction of neural tissue. One change known to occur in neurodegenerative disorders is an accumulation of proteins causing pathological damage.
