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.

Gut microbiome changes improve memory in early cognitive decline

Research shows that modifying the gut microbiome can enhance cognitive performance and mitigate dementia risk, highlighting the gut-brain connection.

The brain encodes time and space through common neural sequences

If you develop Alzheimer's disease, you not only lose your sense of time, but you also lose your sense of place. Could time and place be two sides of the same coin?

New research challenges traditional models of language processing

Multiple regions of the brain engage in fast-moving conversations to understand language, UTHealth Houston researchers have discovered, dispelling a prior school of thought that only one region of the brain was responsible for language processing.

Large study links more siblings to better bereavement coping

Having more brothers and sisters may make it easier to cope with the death of a parent, in midlife, particularly when it's the mother who dies, suggests research published online in the Journal of Epidemiology & Community Health.

Blood test may detect cognitive decline years before symptoms

A blood test could help identify people at higher risk of cognitive decline years before a traditional diagnosis is possible – according to University of East Anglia research.

Polygenic embryo testing raises ethical concerns beyond disease prevention

For more than four decades, in vitro fertilization (IVF) has helped families have children. Scientists estimate that more than 10 million people worldwide have been born through IVF and related assisted reproductive technologies, according to the International Committee for Monitoring Assisted Reproductive Technologies.

What happens when more of your exercise is vigorous instead of moderate?

In a large UK Biobank analysis, a higher proportion of vigorous physical activity relative to total activity volume was associated with lower risks of eight major chronic diseases and all-cause mortality, even after accounting for overall activity volume. Device-based data suggested that activity intensity generally offered greater preventive potential than total volume alone across most outcomes.

Novel compound clears harmful protein, protects neurons in frontotemporal dementia models

New research from Washington University School of Medicine in St. Louis adds to growing evidence that helping brain cells break down and eliminate their own cellular waste is a promising treatment strategy for a variety of neurodegenerative diseases.

Mirror image proteins offer new way to disable Alzheimer's disease

Understanding how proteins interact with their own mirror images enabled a Kobe University research team to design a small mirror protein that disables a causal factor of Alzheimer's disease, amyloid-beta.

Study links atrial fibrillation to poorer brain clearance and cognitive decline

Researchers found that people with atrial fibrillation had lower MRI-based glymphatic activity and poorer cognitive performance than healthy controls, with the greatest impairment seen in non-paroxysmal AF. In patients who underwent catheter ablation, glymphatic activity improved after sinus rhythm was restored, suggesting a possible link between heart rhythm, brain waste clearance, and cognition.

Short bursts of vigorous activity can lower risk of major diseases

People who get just a few minutes of vigorous activity daily are less likely to develop eight major diseases, including arthritis, heart disease and dementia, according to research published in the European Heart Journal today (Monday).

APOE4 alters brain immunity and cognition differently in females and males

APOE4 drove sex-specific changes in meningeal immunity, lymphatic drainage, brain lipids, neuroinflammation, and cognition in mouse models, with females showing greater inflammatory and cognitive vulnerability. Suppressing innate immunity improved some cognitive outcomes in female E4/E4 mice but worsened them in male E4/E4 mice, underscoring the need for sex-tailored approaches.

Investigational drug lowers angiotensinogen but shows unclear blood pressure benefits

The investigational drug tonlamarsen—which is designed to lower blood pressure by reducing the production of angiotensinogen, a protein that turns into the hormone that regulates blood pressure—caused a significant and sustained drop in angiotensinogen but its impact on blood pressure was less clear, according to a study presented at the American College of Cardiology's Annual Scientific Session.

Heart structure changes in midlife linked to long-term disease risk

Higher left atrial end-systolic dimension (LASD), an increased measurement of the left upper chamber of the heart, and left ventricular mass (LVM), a clinical measurement of the weight of the heart's left ventricular myocardium, are well-established indicators of cardiovascular damage that are associated with a higher risk of cardiovascular disease (CVD) in the short-term (less than 10 years).

Mount Sinai team wins million dollar prize for the development of Biomni-AD

A team led by Dr. Kuan-lin Huang, PhD, has been named a winner of the $1 million Alzheimer's Insights AI Prize, the Alzheimer's Disease Data Initiative (AD Data Initiative) announced on March 20. Dr. Huang is an Associate Professor of Genetics and Genomic Sciences at the Icahn School of Medicine at Mount Sinai.

Stroke may trigger younger brain patterns in unaffected regions

In a new study published in The Lancet Digital Health, scientists at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) have discovered that the brains of people who experience severe physical impairment after a stroke may reorganize themselves in unexpected ways, showing signs of "younger" brain structure in undamaged regions as they adapt to injury.
