In the big picture, he said, "the practical, day-to-day utility of this study is small. We just don't know enough yet."
He agrees with Larson that people should not take the drugs purely to prevent Alzheimer's disease, especially since the medications pose risks of gastrointestinal ulcers, bleeding and kidney disease. "The big issue right now is we don't know how to balance the potential benefits against the known risks," Vlad said.
