Please Explain: Alzheimer's Disease and New Alzheimer's Research

Dr. Jerome Groopman, Professor of Medicine at Harvard Medical School, Chief of Experimental Medicine at Beth Israel Deaconess Medical Center, and staff writer for The New Yorker, explains new approaches to Alzheimer's research for this week's Please Explain.

In his latest article, "Before Night Falls," in the June 24 issue of The New Yorker, he looks at the potential of new studies.
