Neuron-Nourishing Cells Appear to Retaliate in Alzheimer's
May 22, 2012 — When brain cells start oozing too much of the amyloid protein that is the hallmark of Alzheimer's disease, the astrocytes that normally nourish and protect them deliver a suicide package instead, ... > full story -
Possible Role of Autoantibodies in Alzheimer’s
May 22, 2012 — Research demonstrates how dying or damaged brain cells give rise to autoantibodies in blood that can be reliable biomarkers for early AD diagnosis. Key mechanism mirrors process common to autoimmune ... > full story -
Pathological Aging Brains Contain the Same Amyloid Plaques as Alzheimer’s Disease
May 21, 2012 — Pathological aging (PA) is used to describe the brains of people which have Alzheimer’s disease (AD)-like pathology but where the person showed no signs of cognitive impairment whilst they were ... > full story -
New Clues on How ApoE4 Affects Alzheimer's Risk
May 16, 2012 — Common variants of the ApoE gene are strongly associated with the risk of developing late-onset Alzheimer's disease, but the gene's role in the disease has been unclear. Now, researchers have found ... > full story -
Alzheimer's Gene Causes Brain's Blood Vessels to Leak Toxins and Die
May 16, 2012 — ApoE4, a well-known genetic risk factor for Alzheimer's disease triggers a cascade of signaling that ultimately results in leaky blood vessels in the brain, allowing toxic substances to pour into ... > full story -
New Understanding of Alzheimer's Trigger
May 2, 2012 — A highly toxic beta-amyloid – a protein that exists in the brains of Alzheimer's disease victims – has been found to greatly increase the toxicity of other more common and less toxic ... > full story -
Eating Fish, Chicken, Nuts May Lower Risk of Alzheimer's Disease
May 2, 2012 — A new study suggests that eating foods that contain omega-3 fatty acids, such as fish, chicken, salad dressing and nuts, may be associated with lower blood levels of a protein related to Alzheimer's ... > full story -
Molecule Blocks Pathway Leading to Alzheimer's Disease
April 30, 2012 — Researchers have found novel compounds that disrupt the formation of amyloid, the clumps of protein in the brains of people with Alzheimer's disease believed to be important in causing the disease's ... > full story -
Prions in the Brain Eliminated by Homing Molecules
April 24, 2012 — Toxic prions in the brain can be detected with self-illuminating polymers. The originators, at Linköping University in Sweden, has now shown that the same molecules can also render the prions ... > full story -
