Review Question - QID 109626

A 67-year-old woman is brought to the emergency room by her son for unusual behavior. She moved into her son’s house 3 years ago after her husband passed away. The son reports that when he returned home from work earlier in the day, he found his mother minimally responsive. She regained consciousness soon after his arrival and did not recall the event. The son also reports that for the past 2 years, his mother has occasionally had trouble remembering where she has placed items around the house. She still goes shopping on her own and cooks regularly. Her past medical history is notable for major depressive disorder, diabetes mellitus, and hypertension. She takes clomipramine, glyburide, lisinopril, and hydrochlorothiazide. She recently saw her primary care provider who adjusted some of her medication dosages. Her temperature is 99°F (37.2°C), blood pressure is 135/75 mmHg, pulse is 80/min, and respirations are 18/min. On examination, she is easily distractible with disorganized speech. She does not recognize her son and thinks that her intravenous line is a rope. She says she feels fine and would like to go home. Brain imaging would likely reveal which of the following?
