A 63-year-old man is brought to the office by his partner for evaluation of impaired memory. About three-months ago, the patient started frequently misplacing objects and having difficulty performing his responsibilities as an accountant. His symptoms worsened two weeks ago, when he developed difficulty walking and frequently tripped over himself. The patient still enjoys playing poker with his friends weekly, but he has found it increasingly difficult to remain competitive. Past medical history is significant for type II diabetes mellitus and hypertension, for which he takes daily medications. His last HbA1c from one month ago was 9.6%.
