Review Question - QID 210618

A 62-year-old man is brought to his primary care physician by his wife because she is concerned that he has become more confused over the past month. Specifically, he has been having difficulty finding words and recently started forgetting the names of their friends. She became particularly worried when he got lost in their neighborhood during a morning walk. Finally, he has had several episodes of incontinence and has tripped over objects because he "does not lift his feet off the ground" while walking. He has a history of hypertension and diabetes but has otherwise been healthy. His family history is significant for many family members with early onset dementia. Which of the following treatments would most likely be effective for this patient?
