by CHeBA Credit: CC0 Public Domain Latest research from UNSW Sydney’s Center for Healthy Brain Aging (CHeBA) has uncovered new insight into the underlying mechanisms of Alzheimer’s disease. The findings, published in Translational Psychiatry, examined differences between the plasma lipidome of people with Alzheimer’s disease and ‘healthy’ individuals of the same age from CHeBA’s Sydney Memory and Aging...
TRINITY COLLEGE DUBLIN New research into Alzheimer’s disease (AD) suggests that secondary infections and new inflammatory events amplify the brain’s immune response and affect memory in mice and in humans – even when these secondary events occur outside the brain. Scientists believe that key brain cells (astrocytes and microglia) are already in an active state...

Dental and orthopedic implants are widely used around the world. Common causes for implant failure are the immune response against oral bacteria and titanium particles shed by the implant. These and other phenomena can generate an inflammatory response, activating the osteoclasts (bone resorbing cells), and ultimately leading to osteolysis (destruction of bone tissue) around the...
by Robin Marks, University of California, San Francisco Credit: CC0 Public Domain While it has been said that the eyes are a window to the soul, a new study shows they could be a means for understanding diseases of the brain. According to new research by scientists at the UCSF Weill Institute for Neurosciences, retinal scans can detect...

by Jenesse Miller, University of Southern California The image displays a TBI-affected brain’s white matter connectivity as inferred using diffusion tensor imaging and streamline tractography. The brain surface is rendered as a translucent layer to provide anatomical context for the streamline display. White matter connections and the brain surface are displayed using different colors across for...
LUND UNIVERSITY Alzheimer’s disease is characterized by the abnormal accumulation and spread of the tau protein in the brain. An international study can now show how tau spreads according to four distinct patterns that lead to different symptoms with different prognoses of the affected individuals. The study was published in Nature Medicine. “In contrast to how...

CREDIT: ALBERT EINSTEIN COLLEGE OF MEDICINE April 22, 2021–(BRONX, NY)–Researchers at Albert Einstein College of Medicine have designed an experimental drug that reversed key symptoms of Alzheimer’s disease in mice. The drug works by reinvigorating a cellular cleaning mechanism that gets rid of unwanted proteins by digesting...
