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.

“Cognitive clock” emerges as a new way to measure brain health

Researchers have developed a novel method to monitor the brain health of patients to improve the early diagnosis and treatment of certain diseases.

Study provides new knowledge about molecular mechanisms underlying human 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 reveals potential mechanism for how traumatic brain injury leads to neurodegenerative diseases

Scientists have revealed a potential mechanism for how traumatic brain injury leads to neurodegenerative diseases, according to a study in fruit flies, and rat and human brain tissue, published today in eLife.

Healthier lifestyle associated with lower risk of cognitive impairment for oldest adults

A new analysis of adults aged 80 years and older shows that a healthier lifestyle is associated with a lower risk of cognitive impairment, and that this link does not depend on whether a person carries a particular form of the gene APOE.

UTokyo researchers study worms to understand the neuroplasticity of learning

As anyone who has ever procrastinated knows, remembering that you need to do something and acting on that knowledge are two different things. To understand how learning changes nerve cells and leads to different behaviors, researchers studied the much simpler nervous system of worms.

Weaker association between brain activity and cerebrospinal fluid flow increases the likelihood of Alzheimer's disease

New imaging research shows that brain activity during sleep was less connected with cerebrospinal fluid flow in patients with Alzheimer's disease.

Study uncovers new mechanism of Alzheimer's that disorganizes blood vessels around amyloid plaques

Researchers at the Biomedicine Institute of Seville have discovered a new mechanism of Alzheimer's disease that disorganizes the blood vessels around amyloid plaques, one of the characteristic features of the disease.

Blood oxygen levels may explain why memory loss is an early symptom of Alzheimer's disease

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.

Poor sleep increases risk of long-term cognitive decline in Hispanics/Latinos

Poor sleep impacts the risk of long-term cognitive decline in Hispanic/Latino middle aged and older adults differently than it does in non-Hispanic adults, according to research led by University of Miami Miller School of Medicine neurology faculty and the largest long-term study of U.S. Hispanic/Latinos to date.

Researchers identify structure of agent that causes Alzheimer's and Parkinson's diseases

Alzheimer's disease - also called dementia - where memory and cognitive functions gradually decline due to deformation and death of neurons, and Parkinson's disease that causes tremors in hands and arms impeding normal movement are major neurodegenerative diseases.

Researchers to conduct Phase 1 gene therapy trial to treat Alzheimer's disease

The National Institute on Aging (NIA), part of the National Institutes of Health, has awarded a $5 million grant to researchers at University of California San Diego School of Medicine to conduct a first-in-human Phase 1 clinical trial of a gene therapy for treating Alzheimer's disease (AD) or Mild Cognitive Impairment (MCI), a condition that often precedes full-blown dementia.

Scientists propose new strategies to find drugs that neutralize critical enzymes

Scientists from the University of Bath explore racemases and propose strategies for finding drugs that target these important enzymes.

Newly identified small molecule can be used to rejuvenate the brain, counteract memory loss

Alzheimer's disease is the main cause of dementia and current therapeutic strategies cannot prevent, slow down or cure the pathology.

New technology makes it easier to diagnose neurodegenerative diseases

A new combination of optical coherence tomography (OCT), adaptive optics and deep neural networks should enable better diagnosis and monitoring for neuron-damaging eye and brain diseases like glaucoma.

Combination of easily accessible tests can enable early, reliable diagnosis of Alzheimer's disease

Researchers at Lund University in Sweden have developed an algorithm that combines data from a simple blood test and brief memory tests, to predict with great accuracy who will develop Alzheimer's disease in the future.

New insights into white matter changes may offer novel targets for prevention, therapies

ince 2008, researchers at Boston University School of Medicine (BUSM) and VA Boston Healthcare System have studied Chronic Traumatic Encephalopathy (CTE), a progressive brain disease associated with repetitive head impacts that has been diagnosed after death in the brains of American football players and other contact sport athletes as well as members of the armed services.

Researchers investigate link between the liver’s immune system composition and NASH pathology

Our livers work hard to perform an entire range of activities: helping us digest food, maintaining body temperature and serving as an important checkpoint of the immune system for everything that we eat.

Could saffron be an effective supplement for helping manage COVID-19?

A new study, published in the journal Cell Press, explores the potential use of saffron (Crocus sativus L.) as a drug supplement for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19).
