Tissue model reveals role of blood-brain barrier in Alzheimer’s

Beta-amyloid plaques, the protein aggregates that form in the brains of Alzheimer's patients, disrupt many brain functions and can kill neurons. They can also damage the blood-brain barrier -- the normally tight border that prevents harmful molecules in the bloodstream... Continue Reading →

An alternate theory for what causes Alzheimer’s disease

Alzheimer's disease, the most common cause of dementia among the elderly, is characterized by plaques and tangles in the brain, with most efforts at finding a cure focused on these abnormal structures. But a University of California, Riverside, research team... Continue Reading →

The ‘Big Bang’ of Alzheimer’s Scientists ID genesis of disease, focus efforts on deadly shape-shifting tau protein

Scientists have discovered a “Big Bang” of Alzheimer’s disease – the precise point at which a healthy protein becomes toxic but has not yet formed deadly tangles in the brain. A study from UT Southwestern’s O’Donnell Brain Institute provides novel... Continue Reading →

How exercise may protect against Alzheimer’s

Athletes know a vigorous workout can release a flood of endorphins: "feel-good" hormones that boost mood. Now there's evidence that exercise produces another hormone that may improve memory and protect against Alzheimer's disease, according to a study co-led by Ottavio... Continue Reading →

Simple drug combination creates new neurons from neighboring cells

 simple drug cocktail that converts cells neighboring damaged neurons into functional new neurons could potentially be used to treat stroke, Alzheimer's disease, and brain injuries. A team of researchers at Penn State identified a set of four, or even three,... Continue Reading →

Research links Tau aggregates, cell death in Alzheimer’s

New evidence suggests a mechanism by which progressive accumulation of Tau protein in brain cells may lead to Alzheimer’s disease. Scientists studied more than 600 human brains and fruit fly models of Alzheimer’s disease and found the first evidence of... Continue Reading →

Memory processes depend on protein ‘off-switch’ – could lead to new Alzheimer’s treatments

Memory, learning and cognitive flexibility depend on a protein ‘off-switch’ in the brain, according to a breakthrough discovery made by an international research collaboration co-led by the University of Warwick.  This new knowledge could enable us to better understand and combat neurological...

Gene Discovered Associated With Tau Pathology

Investigators at Rush University Medical Center and the Brigham and Women’s Hospital in Boston reported the discovery of a new gene that is associated with susceptibility to a common form of brain pathology called Tau that accumulates in several different... Continue Reading →

Head injuries can alter hundreds of genes and lead to serious brain diseases, UCLA biologists report

Head injuries can harm hundreds of genes in the brain in a way that increases people’s risk for a wide range of neurological and psychiatric disorders, UCLA life scientists report. The researchers identified for the first time master genes that... Continue Reading →
