This case study examines the mental state of a Chinese migrant working as a medico in Australia, who is experiencing symptoms of depression and anxiety. The analysis utilizes the Mental State Examination (MSE) and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) to identify potential diagnoses and contributing factors. The MSE reveals signs of depression, including depressed mood, loss of interest, and suicidal ideation. The DSM-V criteria for major depressive disorder are met, and the possibility of postpartum depression in males is explored. The case study also examines the role of stress and vulnerability factors in the patient's mental health, including cultural adjustment difficulties, work-related stress, and the impact of becoming a father. The analysis highlights the importance of addressing these factors in the patient's recovery plan.
