Differential Diagnoses with rationale

Question

C.W. is a tall, thin 78 y.o. African American male brought into the office by his son who states that the patient is restless, angry, and has been unable to sleep for the last week. The son indicates that he is very concerned about his father because he lives alone. Also, he is concerned about the “strange” symptoms that his father has presented with recently.

Background:

C.W. presents as restless, hyperverbal, obnoxious and angry. He expresses himself by periodic yelling. He is unkempt and smells strongly of urine, alcohol and body odor. He has an unsteady gait and sways while standing. As you converse with the son, you determine that C.W. was medically separated from military service due to mental health issues after 2 years of active duty that ended in 1947. He has been married and divorced three times over the years. He typically seeks no acute or preventative medical care. He was treated by a psychiatrist previously, but he did not like taking the prescribed medications so he stopped taking them and did not keep any further psychiatric appointments.
