Your patient is a 77-year-old woman who has been more socially withdrawn lately and told her daughter she had not been feeling well. Her daughter has noticed a stepwise decline. While shopping for groceries with her daughter she became separated from daughter in the aisles. She became confused and angry when store employees and others tried to assist her. Her current medications are Hydrochlorothiazide, Lisinopril and Atorvastatin.
What is your differential diagnosis based on the information you now have?
What other questions would you like to ask her now? (Questions can be asked of patient first, and then of reliable historian separately.)
How would you treat this patient and discuss why you give each medication or therapy you give.
