Which of the following medical professionals primarily specializes in the diagnosis and treatment of mental health conditions?

The choice of psychiatrist is correct because this medical professional is specifically trained to diagnose and treat mental health conditions. Psychiatrists hold medical degrees and are qualified to prescribe medications as well as provide psychotherapy. They have a deep understanding of the complexities of mental health issues, ranging from anxiety and depression to more severe conditions such as schizophrenia or bipolar disorder.

In contrast, the other professions mentioned focus on entirely different areas of healthcare. Podiatrists specialize in the treatment of foot and ankle disorders, dermatologists concentrate on skin-related conditions, and cardiologists are experts in heart-related health issues. Each of these specialties requires different training and focuses on specific physical health aspects rather than mental health, which underscores the distinction of psychiatry in addressing mental health conditions.
