A new study tried to redefine the causes of Alzheimer's disease (AD), arguing that it is likely triggered by the failure of a system that clears wastes from the brain and begins decades before memories fade.
A probe invented at Rice University that lights up when it binds to a misfolded amyloid beta peptide — the kind suspected of causing Alzheimer's disease — has identified a specific binding site on the protein that could facilitate better drugs to treat the disease.
Researchers led by Arizona State University (ASU) and the Translational Genomics Research Institute (TGen) have identified altered expression of a gene called ANK1, which only recently has been associated with memory robbing Alzheimer's disease, in specific cells in the brain.
Deaths from Alzheimer's disease rose by 55 percent over the last 15 years, US federal researchers reported on Thursday. It's probably due to a mix of factors — an aging population, better diagnosis, and more willingness by doctors to put Alzheimer's down as a cause of death, observed the team at the Centers for Disease Control and Prevention.
