A 62-Year-Old Woman Arrives at the Office for a Routine

A 62-year-old woman arrives at the office for a routine exam. Her spouse perished in a bicycle accident that she observed five months ago. She has a low appetite, which has resulted in a weight reduction of 3.17 kg (7 lb) , and she usually wakes up two hours before her alarm clock goes off. "My spouse always took care of the bills so I wouldn't have to worry," the patient says of having to manage the home finances. She no longer cycles, a habit she enjoyed with her husband, but she still volunteers at a children's hospital. There are no nightmares or suicidal thoughts in the patient. During the meeting, she sheds a few tears but grins while recalling a trip she spent with her spouse. Which of the following is the best explanation for this patient's condition?

A) Dependent personality disorder
B) Major depressive disorder
C) Normal grief
D) Persistent complex bereavement disorder
E) Persistent depressive disorder
F) Post-traumatic stress disorder
