CREDIT: DR TAL LAVIV The researchers believe that low-arousal states such as sleep and anesthesia expose failures in a mechanism that regulates stability of brain activity in the early, pre-symptomatic stage of Alzheimer’s disease. This discovery paves the way to early...
It all started with genetic data. A gene here, a gene there. Eventually the story became clearer: If scientists are to one day find a cure for Alzheimer’s disease, they should look to the immune system. Over the past couple decades, researchers have identified numerous genes involved in various immune system functions that may also...

E1 and E2 indicate electrodes on the frontal and parietal cortex, respectively, while reference electrode (R) was placed on cerebellum. G and A correspond to the electrodes for animal grounding and the anchoring screw, respectively. Red dots denote the location of implants...
GIST (GWANGJU INSTITUTE OF SCIENCE AND TECHNOLOGY) IMAGE: ULTRASOUND STIMULATION AS AN EFFECTIVE THERAPY FOR ALZHEIMER’S DISEASE CREDIT: GWANGJU INSTITUTE OF SCIENCE AND TECHNOLOGY With the increase in average life expectancy in many parts of the world, certain age-related diseases have become more common. Alzheimer’s disease (AD), unfortunately, is one of them, being extremely prevalent...

by Case Western Reserve University PET scan of a human brain with Alzheimer’s disease. Credit: public domain An international team led by Case Western Reserve University’s School of Medicine has made a significant breakthrough in understanding why Alzheimer’s disease progresses so rapidly in some people that they die within three years. The researchers found a...
by Molly Chiu, Baylor College of Medicine Credit: Baylor College of Medicine The brain has a natural protective mechanism against Alzheimer’s disease, and researchers at Baylor College of Medicine, Texas Children’s Hospital, and collaborating institutions have discovered that gene variants associated with risk of developing the disease disturb the protective mechanism in ways that can...
