New York, Nov. 6, 2007 – People who have a mother with Alzheimer’s disease appear to be at higher risk for getting the disease than those individuals whose fathers are afflicted, according to a new study by NYU School of Medicine researchers. The study is published in this week’s online edition of the Proceedings of the National Academy of Sciences. It is the first to compare brain metabolism among cognitively normal people who have a father, a mother, or no relatives with Alzheimer’s disease, and to show that only individuals with an affected mother have reduced brain metabolism in the same brain regions as Alzheimer’s patients.
