Psychiatry is the medical specialty devoted to the diagnosis, prevention, and treatment of mental disorders. These include various maladaptations related to mood, behaviour, cognition, and perceptions. See glossary of psychiatry.
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 clinical concepts listed in diagnostic manuals such as the International Classification of Diseases (ICD), edited and used by the World Health Organization (WHO) and the widely used 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 2013 which re-organized the larger categories of various diseases and expanded upon the previous edition to include information/insights that are consistent with current research.
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. An inpatient may be treated in a psychiatric hospital. Research and treatment within psychiatry as a whole are conducted on an interdisciplinary basis with other professionals, such as epidemiologists, nurses, or psychologists.
(sometimes colloquially "benzo
"; often abbreviated "BZD
") is a psychoactive drug
whose core chemical structure is the fusion of a benzene
ring and a diazepine
ring. The first such drug, chlordiazepoxide
(Librium), was discovered accidentally
by Leo Sternbach
in 1955, and made available in 1960 by Hoffmann–La Roche
, which has also marketed the benzodiazepine diazepam
(Valium) since 1963.
Benzodiazepines enhance the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABAA receptor, resulting in sedative, hypnotic (sleep-inducing), anxiolytic (anti-anxiety), anticonvulsant, and muscle relaxant properties; also seen in the applied pharmacology of high doses of many shorter-acting benzodiazepines are amnesic-dissociative actions. These properties make benzodiazepines useful in treating anxiety, insomnia, agitation, seizures, muscle spasms, alcohol withdrawal and as a premedication for medical or dental procedures. Benzodiazepines are categorized as either short-, intermediate-, or long-acting. Short- and intermediate-acting benzodiazepines are preferred for the treatment of insomnia; longer-acting benzodiazepines are recommended for the treatment of anxiety. (Full article...)

(January 4, 1746 [O.S.
December 24, 1745] – April 19, 1813) was a Founding Father of the United States
. Rush lived in the state of Pennsylvania
and was a physician, writer, educator
, humanitarian, as well as the founder of Dickinson College
in Carlisle, Pennsylvania
Rush signed the Declaration of Independence and attended the Continental Congress. He served as Surgeon General in the Continental army, and was blamed for criticising George Washington. Later in life, Rush became a professor of chemistry, medical theory, and clinical practice at the University of Pennsylvania.
As a leading physician, Rush had a major impact on the emerging medical profession. As an Enlightenment intellectual, he was committed to organizing all medical knowledge around explanatory theories, rather than rely on empirical methods. Rush argued that illness was the result of imbalances in the body's physical system and was caused by malfunctions in the brain. His approach prepared the way for later medical research, but Rush himself undertook none of it. He promoted public health by advocating clean environment and stressing the importance of personal and military hygiene. His study of mental disorder made him one of the founders of American psychiatry. (Full article...)
