Scientists from University of California, Irvine, have found a new genetic risk factor for Alzheimer’s disease. In a study of 381 people, those with Alzheimer’s were nearly twice as likely as people without the disease to have a certain form of a gene,TOMM40 (which stands for “translocase of outer mitochondrial membrane 40”). Although the study, released today by the journal PLoS One, can’t be used for treatment any time soon, with luck a better understanding of Alzheimer’s will eventually lead to a cure.
