A local psychiatrist is a physician who is specially trained in diagnosing and treating mental disorders. The main difference between a local psychiatrist and a psychologist is that a local  psychiatrist can prescribe medication in addition to using psychotherapy and other techniques to treat patients. Whether you’re managing a chronic condition such as cancer or arthritis, looking for a diagnosis for bipolar disorder or struggling with anxiety, a local psychiatrist can help. Because there is a connection between your nutrition and mental health, a local psychiatrist can work with your local nutritionist or registered dietitian to create the ideal treatment plan for you.
