Alternative model of Alzheimer's emphasizes different set of mechanisms that lead to neurodegeneration

In the context of recent debate over the FDA's approval of aducanumab, it's refreshing to learn about a model of Alzheimer's neurodegeneration that doesn't start with the pathogenic proteins amyloid or Tau.

Researchers study what happens in brain cells affected by Alzheimer's disease

Studies on tissue from patients and mini-brains made from stem cells shed light on the disease.

USC study suggests new treatment target for Alzheimer's disease in people with APOE4 gene

Like amyloid plaque, the genetic variant APOE4 has long been associated with Alzheimer's disease, but still little is known about the role the gene plays in the disease process.

Researchers use gene therapy to prevent learning, memory loss in Alzheimer's mouse model

Researchers at University of California San Diego School of Medicine, with colleagues elsewhere, have used gene therapy to prevent learning and memory loss in a mouse model of Alzheimer's disease (AD), a key step toward eventually testing the approach in humans with the neurodegenerative disease.

Nutritional supplement may reduce risk of fatal strokes in patients with rare genetic disorder

Researchers from Children's Hospital of Philadelphia (CHOP) have discovered that a widely used nutritional supplement may significantly reduce the risk of fatal strokes caused by a rare genetic disorder.

CBD ameliorates cognitive function in experimental model of familial Alzheimer's

A two-week course of high doses of CBD helps restore the function of two proteins key to reducing the accumulation of beta-amyloid plaque, a hallmark of Alzheimer's disease, and improves cognition in an experimental model of early onset familial Alzheimer's, investigators report.

New drug could prevent Alzheimer's by modulating key enzyme involved in amyloid plaque formation

Amyloid plaques are pathological hallmarks of Alzheimer's disease (AD) -- clumps of misfolded proteins that accumulate in the brain, disrupting and killing neurons and resulting in the progressive cognitive impairment that is characteristic of the widespread neurological disorder.

Researchers identify antibody that removes amyloid plaques without the risk of brain bleeds

As people age, a normal brain protein known as amyloid beta often starts to collect into harmful amyloid plaques in the brain. Such plaques can be the first step on the path to Alzheimer's dementia.

Study: Cognitive SuperAgers resist protein tangles that lead to Alzheimer’s disease

A new Northwestern Medicine study showed cognitive SuperAgers have resistance to the development of fibrous tangles in a brain region related to memory and which are known to be markers of Alzheimer's disease.

UQ researchers discover how the brain 'tangles' in Alzheimer's disease and dementia

University of Queensland researchers have discovered a new 'seeding' process in brain cells that could be a cause of dementia and Alzheimer's disease.

Genetic differences play a vital role in early diagnosis of Alzheimer's disease

The two clinically used methods for detecting amyloid pathology in Alzheimer's disease do not give unambiguous results, with the risk of incorrect or delayed care interventions.

Research can bring new possibilities for earlier diagnosis, preventive treatment of dementia

Researchers at Karolinska Institutet in Sweden have studied the incidence and regional distribution of Alzheimer's disease biomarkers in the brains of people with Down's syndrome.

MU researcher develops procedures for defining the preclinical stages of Alzheimer's disease

Both of Andrew Kiselica's grandfathers developed dementia when he was in graduate school. As Kiselica was going through neuropsychology training in graduate school, he saw his mother's father become unable to walk or speak due to severe dementia.

Study shows how amyloid fibrils in Alzheimer's dissociate with infrared laser irradiation

The agglomeration of proteins into structures called amyloid plaques is a common feature of many neurodegenerative diseases, including Alzheimer's.

New method can detect small amounts of protein fragment linked to Alzheimer's disease

Researchers at Washington University School of Medicine in St. Louis have developed a technique to detect minute amounts of a protein fragment linked to Alzheimer's disease in the blood.

Simple blood test may be a great advance for people with and at risk for Alzheimer's

A simple blood test for Alzheimer's would be a great advance for individuals with -; and at risk for -; the disease, families, doctors and researchers.

Salmonella biofilm protein can cause autoimmune responses, arthritis in animals

Scientists from the Vaccine and Infectious Disease Organization-International Vaccine Centre at the University of Saskatchewan and Temple University have demonstrated that a Salmonella biofilm protein can cause autoimmune responses and arthritis in animals.
