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.
Researchers who examined human brains confirmed that people who eat more seafood have more mercury in their brains. But, they found no link between higher brain levels of that neurotoxin and the kind of brain damage that is typical of Alzheimer's disease and dementia.
