A thorough psychiatric assessment relies on integrating medical and mental health information from the start. Medical issues can masquerade as, or worsen, psychiatric symptoms, and they can influence treatment choices and safety. So the best approach combines a physical examination with targeted laboratory tests and a structured psychological evaluation. The physical exam and labs help uncover conditions like thyroid disorders, infections, metabolic problems, or substance use that could be driving or complicating mood, behavior, or cognition. Thyroid dysfunction, for example, can produce depressive or anxious symptoms, while screening for alcohol or drugs reveals substances that can mimic psychiatric illness or interact with medications. The psychological evaluation is essential to assess current mental status, mood, thought content, risk of harm to self or others, and psychosocial factors that influence diagnosis and care. Together, this integrated assessment ensures an accurate picture, guides safe and effective treatment, and helps distinguish primary psychiatric disorders from medical mimics. Relying on only a psychological evaluation misses medical contributors; using medical history alone omits current status and mental symptoms; and skipping medical assessment altogether risks missing treatable medical causes.
