Problem: Use DSM-5 to give 3 differential diagnoses. Then explain them from 1st to last. A 50-year-old man undergoing psychotherapy is grappling with feelings of depression linked to his wife's lupus, which has strained their communication and hindered his ability to connect with her, resulting in anger and frustration. He is particularly worried about her interactions, especially concerning her friend's mother's cancer diagnosis, as he perceives that she has difficulty with focus and memory. Since his retirement in 2021, he has experienced a significant change in his daily routine, which, although not the main cause of his depression, contributes to his occasional low mood. Additionally, he expresses concern for his daughter, a single mother with an autistic son, feeling helpless when he is distant during crises. His sleep is irregular, averaging around four hours per night, leaving him feeling unrefreshed, which he attributes to a history of demanding work. He is motivated to enhance his sleep quality.
