Alzheimer's Disease News and Research

Alzheimer's disease (AD) is an irreversible, progressive brain disease that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks of daily living. In most people with AD, symptoms first appear after age 60. AD is the most common cause of dementia among older people, but it is not a normal part of aging. Dementia refers to a decline in cognitive function that interferes with daily life and activities. AD starts in a region of the brain that affects recent memory, then gradually spreads to other parts of the brain. Although treatment can slow the progression of AD and help manage its symptoms in some people, currently there is no cure for this devastating disease.

Collaborative initiative seeks to uncover ways to reduce Alzheimer’s and dementia risk

The Triangulation of Innovative Methods to End Alzheimer's Disease project will use large, diverse datasets to examine whether interventions targeting alcohol use, depression, vision or hearing impairments, or social isolation can protect people from Alzheimer's disease and related dementias.

Two genetic variants linked to Alzheimer's trigger microglial inflammation in females

Weill Cornell Medicine investigators have found that two genetic variants that confer high risk of Alzheimer's disease (AD) together trigger a harmful inflammatory response in the brain's immune cells, particularly in females, in a preclinical model.

Falls linked to increased risk of dementia in older adults

In a retrospective study of Medicare claims data, researchers found dementia was more frequently diagnosed within one year of a fall compared to other types of injuries.

Study explores whether certain brain proteins may play a role in Alzheimer's development

With a four-year, $3.3 million grant from the National Institutes of Health (NIH), researchers from Case Western Reserve University will study whether certain brain proteins may play a role in the development of Alzheimer's disease.

New insights into astrocytes offer hope for Alzheimer's treatment

A research team led by Dr. Hoon Ryu from the Korea Institute of Science and Technology (KIST, President Sang-Rok Oh) Brain Disease Research Group, in collaboration with Director Justin C. Lee of the Institute for Basic Science (IBS, President Do-Young Noh) and Professor Junghee Lee from Boston University Chobanian & Avedisian School of Medicine, has uncovered a new mechanism involving astrocytes for treating Alzheimer's disease (AD) and proposed a novel therapeutic target.

Phytoene increases lifespan, reduces oxidative stress and amyloid toxicity

Research indicates phytoene from microalgae protects against oxidative stress and beta-amyloid toxicity, suggesting its potential in promoting healthy aging.

Carotenoid phytoene shows potential in slowing Alzheimer’s plaque formation and increasing lifespan

Researchers from the Colour and Food Quality group at the Faculty of Pharmacy (University of Seville), in collaboration with Dr. Marina Ezcurra's group at the University of Kent (UK), have shown that the carotenoid phytoene increases the lifespan of the nematode Caenorhabditis elegans and can slow the onset of paralysis associated with the formation of amyloid plaques in a model of Alzheimer's disease.

Centenarians' stem cells unlock secrets to healthy aging

Individuals who display exceptional longevity provide evidence that humans can live longer, healthier lives.

Concerns raised over safety and effectiveness of donanemab for Alzheimer’s treatment

The safety and effectiveness of donanemab - an Alzheimer's drug recently approved by the US Food & Drug Administration (FDA) - is called into question in an investigation published by The BMJ today.

Increasing daily consumption of flavonoid-rich foods may lower dementia risk

Research shows that flavonoid-rich diets, including tea and red wine, are associated with a lower risk of dementia in genetically susceptible individuals.

Calcium channel blockers show potential to restore cerebral blood flow in Alzheimer's disease

Targeting calcium channels in pericytes may improve blood flow in Alzheimer's disease, addressing early vascular dysfunction linked to cognitive deficits.

Blood microRNAs can predict conversion from mild cognitive impairment to dementia due to Alzheimer’s disease

This study identifies serum miRNA signatures as promising biomarkers for Alzheimer's, enhancing prediction of MCI conversion to AD with clinical relevance.

Amyloid-β and tau disrupt brain activity, driving early cognitive decline in Alzheimer’s risk

Researchers discover how amyloid-β and tau pathologies interact to drive early neurophysiological changes and cognitive decline in older adults at risk of Alzheimer’s disease.

Plasma pTau181 predicts Alzheimer’s progression in real-world memory clinic patients

Researchers confirm plasma pTau181 is a strong predictor for Alzheimer's in patients with mild cognitive impairment, offering a less invasive diagnostic tool for early intervention.

New biomarkers offer hope for early detection and prevention of Alzheimer's

The failure to diagnose Alzheimer's disease, the most common form of dementia in the elderly, at an early stage of molecular pathology is considered a major reason why treatments fail in clinical trials. Previous research to molecularly diagnose Alzheimer's disease yielded "A/T/N" central biomarkers based on the measurements of proteins, β-amyloid ("A") and tau ("T"), and "N" encompassing neurodegeneration. A/T/N can be measured in brain tissue, by in vivo brain imaging techniques, and by analysis of cerebrospinal fluid and plasma.

Leptin variations may influence brain health and dementia development

New research is more closely linking obesity to dementia. Higher levels of leptin, a hormone that helps maintain normal body weight, is associated with better signal-transmitting brain white matter in middle-aged adults, according to a study by The University of Texas Health Science Center at San Antonio (UT Health San Antonio).

Study helps explain why having ApoE4 increases risk of neurodegeneration

A new study helps explain why having ApoE4—the gene variant most closely linked to Alzheimer's disease—increases the risk of neurodegeneration and white matter damage.

Study links diabetes drugs to lower risk of dementia and Parkinson's disease

A class of drugs for diabetes may be associated with a lower risk of dementia and Parkinson's disease, according to a study published in the September 18, 2024, online issue of Neurology, the medical journal of the American Academy of Neurology.

Understanding brain activity shifts in Alzheimer’s disease

Amyloid-beta and tau proteins have long been associated with Alzheimer's disease. The pathological buildup of these proteins leads to cognitive decline in people with the disease.
