Alzheimer's Disease News and Research

RSS

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.

Single biomarker in the blood can accurately indicate underlying neurodegeneration

Levels of a protein called neurofilament light chain (NfL) in the blood can identify those who might have neurodegenerative diseases such as Down's syndrome dementia, motor neuron disease (ALS) and frontotemporal dementia, when clinical symptoms are not definitive.

New study on genotype-phenotype associations sheds light on human complex traits, diseases

A new study analyzing the association between an individual's genetics (genotype) and their observable characteristics resulting from the interaction of genetics and the environment (phenotype), contributes new knowledge to the understanding of human complex traits and diseases.

Study shows why “the brain's memory center” is vulnerable to damage, degeneration

In a world first, scientists from the University of Sussex have recorded blood oxygen levels in the hippocampus and provided experimental proof for why the area, commonly referred to as 'the brain's memory center', is vulnerable to damage and degeneration, a precursor to Alzheimer's disease.

Researchers suggest new strategies for finding drugs that neutralize key enzymes

Scientists from the UK's University of Bath explore racemases - an important type of enzyme that is linked to certain cancers and other life-threatening diseases while also being critical to cell function - in a paper published in the prestigious journal Chemical Society Reviews. The scientists also propose new strategies for finding drugs that neutralize these enzymes.

Researchers devise a small-molecule cocktail to protect stem cells from stress

Researchers at the National Institutes of Health (NIH) have devised a four-part small-molecule cocktail that can protect stem cells called induced pluripotent stem cells (iPSCs) from stress and maintain normal stem cell structure and function.

Chaperone protein imbalance initiates toxic accumulation of tau in the aging brain

Chaperone protein imbalance can play a significant role in initiating toxic accumulation of tau in the aging brain - an early step in the development of Alzheimer's disease and related neurodegenerative disorders known as tauopathies, a new preclinical study by University of South Florida Health (USF Health) neuroscientists suggests.

Study shows how tau aggregates promote Alzheimer’s disease

If looked deep into the brain of a patient with Alzheimer’s disease or those suffering from the most types of dementia or the concussion-associated syndrome, called chronic traumatic encephalopathy (CTE), there would be hairball-like tangles of a protein known as tau—a common suspected culprit.

Researchers identify overlapping genetic locations that shape face and the brain

An interdisciplinary team led by KU Leuven and Stanford has identified 76 overlapping genetic locations that shape both our face and our brain.

Processed meat consumption associated with increased risk of dementia

Scientists from the University of Leeds's Nutritional Epidemiology Group used data from 500,000 people, discovering that consuming a 25g serving of processed meat a day, the equivalent to one rasher of bacon, is associated with a 44% increased risk of developing the disease.

New high-throughput system for testing drug candidates to treat neurodegenerative diseases

On the basis of a license agreement with the German Center for Neurodegenerative Diseases (DZNE) and the Leibniz Institute of Polymer Research Dresden (IPF), the Dresden-based start-up "Neuron-D GmbH" is developing a high-throughput system for testing drug candidates to treat neurodegenerative diseases.

Comprehensive mutation map helps better understand the biological processes underlying Alzheimer's

A study published in the journal eLife made all the possible mutations in the amyloid beta peptide and tested how they influence its aggregation into plaques, a pathological hallmark of Alzheimer's disease.

First-in-human clinical trial to test safety, efficacy of gene therapy for Alzheimer's disease

Researchers at University of California San Diego School of Medicine have launched a first-in-human Phase I clinical trial to assess the safety and efficacy of a gene therapy to deliver a key protein into the brains of persons with Alzheimer's disease (AD) or Mild Cognitive Impairment (MCI), a condition that often precedes full-blown dementia.

Antioxidant in green tea may lead to new anti-cancer drugs

Green tea contains an antioxidant that may boost the concentrations of p53, called the “guardian of the genome,” for its potential to kill cancerous cells.

$1.8 million NIH grant supports research on extracellular vesicles

Scientists have known for decades that our cells constantly shed tiny pieces known as extracellular vesicles (EVs), but until relatively recently they believed that this process was merely a way for cells to rid themselves of material that was no longer needed.

Study provides a causal link between the Alzheimer's risk gene and COVID-19

A City of Hope-led research team found that the same gene that increases the risk for Alzheimer's disease, ApoE4, can increase the susceptibility to and severity of COVID-19.
