Shock Therapy (psychiatry)
Shock therapy describes a set of techniques used in psychiatry to treat depressive disorder or other illnesses, by inducing seizures or other extreme brain states. It was started in the 1930s. Shock therapy covers multiple forms. The only form in current clinical practice is electroconvulsive therapy. Other forms, no longer in use, include: *Insulin shock therapy, introduced by Manfred Sakel in 1933 for the treatment of schizophrenia. This resulted in a coma state for a short amount of time. *Convulsive therapy, using pentylenetetrazol or other agents to induce seizures. The first use was with cardiazol by von Meduna of Budapest; the belief at the time was there was "some kind of biological antagonism between schizophrenia and epilepsy". *Deep sleep therapy. Shock therapy has fallen away in use in lieu of other forms of treatment.

Electroconvulsive Therapy
Electroconvulsive therapy (ECT) is a psychiatry, psychiatric treatment where a generalized seizure (without muscular convulsions) is electrically induced to manage refractory mental disorders.Rudorfer, MV, Henry, ME, Sackeim, HA (2003)"Electroconvulsive therapy". In A Tasman, J Kay, JA Lieberman (eds) ''Psychiatry, Second Edition''. Chichester: John Wiley & Sons Ltd, 1865–1901. Typically, 70 to 120 volts are applied externally to the patient's head, resulting in approximately 800 amperes, milliamperes of direct current passing between the electrodes, for a duration of 100 milliseconds to 6 seconds, either from temple to temple (bilateral ECT) or from front to back of one side of the head (unilateral ECT). However, only about 1% of the electrical current crosses the bony skull into the brain because skull Electrical impedance, impedance is about 100 times higher than skin Electrical impedance, impedance. The ECT procedure was first conducted in 1938 by Italian psychiatrist Ugo C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insulin Shock Therapy
Insulin shock therapy or insulin coma therapy was a form of psychiatric treatment in which patients were repeatedly injected with large doses of insulin in order to produce daily comas over several weeks.Neustatter WL (1948) ''Modern psychiatry in practice.'' London: 224. It was introduced in 1927 by Austrian-American psychiatrist Manfred Sakel and used extensively in the 1940s and 1950s, mainly for schizophrenia, before falling out of favour and being replaced by neuroleptic drugs in the 1960s. It was one of a number of physical treatments introduced into psychiatry in the first four decades of the 20th century. These included the convulsive therapies ( cardiazol/metrazol therapy and electroconvulsive therapy), deep sleep therapy, and psychosurgery. Insulin coma therapy and the convulsive therapies are collectively known as the shock therapies. Origins In 1927, Sakel, who had recently qualified as a medical doctor in Vienna and was working in a psychiatric clinic in Berlin, b ...

Manfred Sakel
Manfred Joshua Sakel (June 6, 1900 – December 2, 1957) was an Austrian-Jewish (later Austrian-American) neurophysiologist and psychiatrist, credited with developing insulin shock therapy in 1927. Biography Sakel was born on June 6, 1900, in Nadvirna (Nadwórna), in the former Austria-Hungary Empire (now Ukraine), which was part of Poland between the world wars. Sakel studied Medicine at the University of Vienna from 1919 to 1925, specializing in neurology and neuropsychiatry. From 1927 until 1933 Sakel worked in hospitals in Berlin. In 1933 he became a researcher at the University of Vienna's Neuropsychiatric Clinic. In 1936, after receiving an invitation from Frederick Parsons, the state commissioner of mental hygiene, he chose to emigrate from Austria to the United States of America. In the USA, he became an attending physician and researcher at the Harlem Valley State Hospital. Dr. Sakel was the developer of insulin shock therapy from 1927 while a young doctor in Vienna, sta ...

Schizophrenia
Schizophrenia is a mental disorder characterized by continuous or relapsing episodes of psychosis. Major symptoms include hallucinations (typically hearing voices), delusions, and disorganized thinking. Other symptoms include social withdrawal, decreased emotional expression, and apathy. Symptoms typically develop gradually, begin during young adulthood, and in many cases never become resolved. There is no objective diagnostic test; diagnosis is based on observed behavior, a history that includes the person's reported experiences, and reports of others familiar with the person. To be diagnosed with schizophrenia, symptoms and functional impairment need to be present for six months (DSM-5) or one month (ICD-11). Many people with schizophrenia have other mental disorders, especially substance use disorders, depressive disorders, anxiety disorders, and obsessive–compulsive disorder. About 0.3% to 0.7% of people are diagnosed with schizophrenia during their lifetime. In 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pentylenetetrazol
Pentylenetetrazol, also known as pentylenetetrazole, leptazol, metrazol, pentetrazol (INN), pentamethylenetetrazol, Corazol, Cardiazol, Deumacard, or PTZ, is a drug formerly used as a circulatory and respiratory stimulant. High doses cause convulsions, as discovered by Hungarian-American neurologist and psychiatrist Ladislas J. Meduna in 1934. It has been used in convulsive therapy, and was found to be effective—primarily for depression—but side effects such as uncontrolled seizures were difficult to avoid. In 1939, pentylenetetrazol was replaced by electroconvulsive therapy, which is easier to administer, as the preferred method for inducing seizures in England's mental hospitals. In the US, its approval by the Food and Drug Administration was revoked in 1982. It is used in Italy as a cardio-respiratory stimulant in combination with codeine in a cough suppressant drug. Mechanism The mechanism of pentylenetetrazol is not well understood, and it may have multiple mechanisms o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deep Sleep Therapy
Deep sleep therapy (DST), also called prolonged sleep treatment or continuous narcosis, is a discredited form of ostensibly psychiatric treatment in which drugs are used to keep patients unconscious for a period of days or weeks. The controversial practice led to the death of 25 patients in Chelmsford Private Hospital in New South Wales from the early 1960s to late 1970s. History Induction of sleep for psychiatric purposes was first tried by Scottish psychiatrist Neil Macleod at the turn of the 20th century. He used sodium bromide to induce sleep in a few psychiatric patients, one of whom died. His method was adopted by some other physicians but soon abandoned, perhaps because it was considered too toxic or reckless. In 1915, Giuseppe Epifanio tried barbiturate-induced sleep therapy in a psychiatric clinic in Italy, but his reports made little impact. Electronarcosis was also developed and used for various psychiatric disorders, involving current passed through the brain to induc ...

History Of Psychiatry
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...
