The Psychiatry Portal

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.

A benzodiazepine /ˌbɛnzoʊdaɪˈæzɪpiːn/ (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 GABA_A 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

Thomas Stephen Szasz (/ˈsɑːs/ SAHSS; April 15, 1920 – September 8, 2012) was a psychiatrist and academic, a Fellow of the American Psychiatric Association, a member of the American Psychoanalytic Association, a professor of psychiatry at the State University of New York, and starting in 1990, he was professor emeritus of psychiatry at the State University of New York Upstate Medical University in Syracuse. He was well known as a social critic of the moral and scientific foundations of psychiatry, of what he saw as social control aims of medicine in modern society, and scientism. His books The Myth of Mental Illness (1961) and The Manufacture of Madness (1970) set out some of the arguments he is most associated with.

Szasz argued that mental illnesses are not real in the sense that cancers are real. Except for a few identifiable brain diseases, such as Alzheimer's disease, there are “neither biological or chemical tests nor biopsy or necropsy findings for verifying or falsifying DSM diagnoses", i.e. there are no objective methods for detecting the presence or absence of mental illness.(Full article...)
