In spite of what must be a hectic schedule, the physician took time to indicate what kinds of information will be gathered in order to ascertain where we proceed in future. I felt that even if the diagnosis is dire, at least I can rest assured that everything that can be done will be accomplished through the staff and my efforts.

In all my nearly 81 years, I believe I can factually state that Dr. S. is as brilliant a doctor as anyone I have ever seen for any medical problem. His knowledge of the broad subject of demential and all it implies that he imparted to me has given me at least 10 more years of fruitful and productive life, something I thought I had lost before coming to this clinic. This is a gift not often received by patients from their physicians. The "Thinking" publication, which I understand Dr. S. had a hand in, was informative on so many levels that I appreciated being given the opportunity to learn so much about Cleveland Clinic Lou Ruvo Brain Health Center.
