A 68-year-old man is evaluated for memory difficulty that, according to his wife, began insidiously 3 or 4 years earlier. He has difficulty remembering recent events. For example, he forgets appointments and recent conversations and forgot that a close relative had recently died. He is no longer able to manage his own checkbook or operate his car without getting lost. Medical history is otherwise unremarkable. Physical examination findings, including vital signs, are normal. Mental status examination shows prominent memory loss and difficulty drawing a complex figure. Laboratory studies show that a complete blood count and routine chemistries are normal. An MRI of the brain shows only mild cerebral atrophy. Which of the following is the most likely diagnosis?
(A) Alzheimer dementia
(B) Creutzfeldt-Jakob disease
(C) Dementia with Lewy bodies
(D) Frontotemporal dementia
