Psychiatry
branch of medicine devoted to the study, diagnosis, treatment, and prevention of mental disorders
Psychiatry is the medical specialty devoted to the diagnosis, treatment, and prevention of deleterious mental conditions. These include matters related to cognition, perceptions, mood, emotion, and behavior.
Initial psychiatric assessment begins with taking a case history and conducting a mental status examination. Laboratory tests, physical examinations, and psychological assessments may also be used. On occasion, neuroimaging or neurophysiological studies are performed.
Disorders
Mental disorders are diagnosed in accordance with diagnostic manuals such as the International Classification of Diseases (ICD), edited by the World Health Organization (WHO), and the Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association (APA). The fifth edition of the DSM (DSM-5) was published in May 2013. However, its release coincided with a statement by then-NIMH (National Institute of Mental Health) director Thomas Insel noting that the manual lacks validity compared to other medical specialties due to the absence of objective laboratory measures (biomarkers) for diagnosis.
Treatment may include psychotropics (psychiatric medicines), psychotherapy, substance-abuse treatment, and other modalities such as interventional approaches, 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 risk to the individual or community.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Psychiatry”, the useful work is to connect “branch of medicine devoted to the study, diagnosis, treatment, and prevention of mental disorders” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 8, 2026. The linked authority identifier is Q7867. The Library of Congress control number is sh85108381. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2013.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
