Medical professionals who specialize in neuropsychiatry work to help patients who have mental illnesses that can be directly attributed to neurological disorders or problems. This field has grown in recent years as it has become clearer that many mental illnesses are the result of physical problems of the brain. It is a more specialized field than their neurology or psychiatry, and therefore, patients must seek out this specific type of care if their mental illness is related to a brain disorder.

Optometry is a medical profession that deals with the eyes and eye health. Optometrists can look at patients’ eyes to address abnormalities or irregularities as well as diagnose diseases of the eye. These doctors may also refer patients to surgeons who can correct eye problems. While optometrists do also focus on helping people find corrective lenses that can improve their vision, their focus extends far beyond glasses and contacts to include overall eye health, including management of eye diseases.

Psychiatrists are doctors who specialize in treating mental, addictive, and emotional disorders. They order diagnostic tests, prescribe medications, and use psychotherapy to help patients and their family members deal with these disorders and diseases. They often work with other doctors and specialists to help come up with the best treatment option for their patients.
