Psychiatry is the medical specialty devoted to the diagnosis, prevention, and treatment of deleterious mental conditions. These include various matters related to mood, behaviour, cognition, perceptions, and emotions.

Initial psychiatric assessment of a person begins with creating a case history and conducting a mental status examination. Physical examinations, psychological tests, and laboratory tests may be conducted. On occasion, neuroimaging or other neurophysiological studies are performed. 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), published in May 2013, reorganized the categories of disorders and added newer information and insights consistent with current research.

Treatment may include psychotropics (psychiatric medicines) and psychotherapy, and also other modalities such as assertive community treatment, community reinforcement, substance-abuse treatment, 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. Research within psychiatry is conducted on an interdisciplinary basis with other professionals, such as epidemiologists, nurses, social workers, occupational therapists, and clinical psychologists.

Core structure of the benzodiazepines
A benzodiazepine /ˌbɛnzdˈæzɪpn/ (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...)

Selected biography

Alfred W. Adler (February 7, 1870 – May 28, 1937) was an Austrian medical doctor, psychotherapist, and founder of the school of individual psychology. His emphasis on the importance of feelings of inferiority—the inferiority complex—is recognized as isolating an element which plays a key role in personality development. Alfred Adler considered human beings as an individual whole, therefore he called his psychology "Individual Psychology" (Orgler 1976). Adler was the first to emphasize the importance of the social element in the re-adjustment process of the individual and who carried psychiatry into the community.

In collaboration with Sigmund Freud and a small group of Freud's colleagues, Adler was among the co-founders of the psychoanalytic movement and a core member of the Vienna Psychoanalytic Society: indeed, to Freud he was "the only personality there". He was the first major figure to break away from psychoanalysis to form an independent school of psychotherapy and personality theory, which he called individual psychology because he believed a human to be an indivisible whole, an individuum. He also imagined a person to be connected or associated with the surrounding world. (Full article...)
