Did anyone catch The Today Show this morning? Katie Couric interviewed someone identified as "Dr. Yaakov Stern from Columbia University College of Physicians and Surgeons" who spoke rather intelligently about the current state of research and treatment of Alzheimer's Disease. He even discussed pharmacotherapy a bit. I was under the impression that he was a neurologist, but after looking him up, found out that he's a clinical neuropsychologist.

I didn't catch the show, but the name sounds really familiar. He may have done some other shows on alzheimer's that I caught.
