The Colombian clan that helps better understand Alzheimer's
Scientists say they've found a network of genes and their subsequent mutations that either speed up or delay the onset of Alzheimer's disease. The finding results from a study carried out within a Colombian extended family of 5,000 people descended from one Spaniard. Lead researcher Dr Maurice Arcos-Burgos from the Australian National University in Canberra says that some of the people contracted the disease in their 30s, other developed it in their 70s. The scientist told Newsday how the mutating genes work.
