"Psychiatry is the branch of medicine devoted to the diagnosis, prevention, study, and treatment of mental disorders. These include various abnormalities that are affective, behavioural, cognitive, and perceptual.
Initial psychiatric assessment of a person typically begins with a case history and mental status examination. Physical examinations and psychological tests may be conducted. On occasion, neuroimaging or other neurophysiological techniques are used. Mental disorders are often diagnosed in accordance with criteria listed in diagnostic manuals such as the widely used Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association, and the International Classification of Diseases (ICD), edited and used by the World Health Organization. The fifth edition of the DSM (DSM-5) was published in 2013, and its development was expected to be of significant interest to many medical fields.
The combined treatment of psychiatric medication and psychotherapy has become the most common mode of psychiatric treatment in current practice, but contemporary practice also includes a wide variety of other modalities, e.g., assertive community treatment, community reinforcement, and supported employment.
Treatment may be delivered on an inpatient or outpatient basis, depending on the severity of functional impairment or on other aspects of the disorder in question. Research and treatment within psychiatry as a whole are conducted on an interdisciplinary basis, e.g., with epidemiologists, mental health counselors, nurses, psychologists, public health specialists, radiologists, and/or social workers."
