Robert Galbraith Heath
Robert Galbraith Heath (May 9, 1915 – September 21, 1999) was an American psychiatrist. He followed the theory of biological psychiatry that organic defects were the sole source of mental illness, and that consequently mental problems were treatable by physical means. He published 425 papers and three books. One of his first papers is dated 1946. He was profiled as a "famous American psychiatrist" in 1983 by ''Psychiatric Annals''. Heath founded the Department of Psychiatry and Neurology at Tulane University, New Orleans, in 1949 and remained its chairman until 1980. He performed many experiments there involving electrical stimulation of the brain via surgically implanted electrodes. He placed deep brain stimulation (DBS) electrodes into the brains of more than 54 patients. Indeed, he has been cited as the first, or one of the first, researcher(s) to have placed electrodes deep into the brains of living human patients. It has been suggested that this work was financed in part b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychiatry
Psychiatry is the specialty (medicine), 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 Medical history, case history and mental status examination. Physical examinations and Psychological testing, psychological tests may be conducted. On occasion, neuroimaging or other Neurophysiology, 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 May 2013 which re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Septal Nuclei
The septal area (medial olfactory area), consisting of the lateral septum and medial septum, is an area in the lower, posterior part of the medial surface of the frontal lobe, and refers to the nearby septum pellucidum. The septal nuclei are located in this area. The septal nuclei are composed of medium-size neurons which are classified into dorsal, ventral, medial, and caudal groups. The septal nuclei receive reciprocal connections from the olfactory bulb, hippocampus, amygdala, hypothalamus, midbrain, habenula, cingulate gyrus, and thalamus. The septal nuclei are essential in generating the theta rhythm of the hippocampus. The septal area (medial olfactory area) has no relation to the sense of smell, but it is considered a pleasure zone in animals. The septal nuclei play a role in reward and reinforcement along with the nucleus accumbens. In the 1950s, Olds & Milner showed that rats with electrodes implanted in this area will self-stimulate repeatedly (i.e., press a bar to re ...

DSM-II
The ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM; latest edition: DSM-5-TR, published in March 2022) is a publication by the American Psychiatric Association (APA) for the classification of mental disorders using a common language and standard criteria and is the main book for the diagnosis and treatment of mental disorders in the United States and is considered one of the "Bibles" of psychiatry along with the ICD, CCMD and the Psychodynamic Diagnostic Manual. It is usedmainly in the United Statesby researchers, psychiatric drug regulation agencies, health insurance companies, pharmaceutical companies, the legal system, and policymakers. Mental health professionals use the manual to determine and help communicate a patient's diagnosis after an evaluation. Hospitals, clinics, and insurance companies in the United States may require a DSM diagnosis for all patients with mental disorders. Health-care researchers use the DSM to categorize patients for research ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paroxysmal Attack
Paroxysmal attacks or paroxysms (from Greek παροξυσμός) are a sudden recurrence or intensification of symptoms, such as a spasm or seizure. These short, frequent symptoms can be observed in various clinical conditions. They are usually associated with multiple sclerosis or pertussis, but they may also be observed in other disease, disorders such as encephalitis, head Physical trauma, trauma, stroke, asthma, trigeminal neuralgia, breath-holding spells, epilepsy, malaria, tabes dorsalis, and Behçet's disease, paroxysmal nocturnal hemoglobinuria (PNH). It has also been noted as a symptom of gratification disorder in children. The word wikt:paroxysm, paroxysm means "sudden attack, outburst", and comes from the Greek language, Greek παροξυσμός (''paroxusmos''), "irritation, exasperation".

Taraxein
Taraxein is a possibly nonexistent protein isolated from the blood of patients with schizophrenia, claimed by Robert Galbraith Heath to produce schizophrenia-like symptoms when injected into healthy subjects.Heath RG, Mårtens S, Leach BE, Cohen M, Angel C (1957): Effect on behavior in humans with the administration of taraxein. Am J Psychiatry, 114: 14–24. Despite initial interest, attempts at confirmation failed. The results are today commonly assumed to be due to self-deception.Alan Baumeistera, The Search for an Endogenous Schizogen: The Strange Case of Taraxein, Journal of the History of the Neurosciences: Basic and Clinical Perspectives Volume 20, Issue 2, 2011 p. 106-102 The name is derived from the Greek word τάραξις (taraxis), meaning disordered or confused mind. Taraxein was discovered during the investigation of the hypothesis that catecholamine metabolism is altered in schizophrenia. A blue substance was found in extracts from people with schizophrenia but not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brain Abscess
Brain abscess (or cerebral abscess) is an abscess caused by inflammation and collection of infected material, coming from local (ear infection, dental abscess, infection of paranasal sinuses, infection of the mastoid air cells of the temporal bone, epidural abscess) or remote ( lung, heart, kidney etc.) infectious sources, within the brain tissue. The infection may also be introduced through a skull fracture following a head trauma or surgical procedures. Brain abscess is usually associated with congenital heart disease in young children. It may occur at any age but is most frequent in the third decade of life. Signs and symptoms Fever, headache, and neurological problems, while classic, only occur in 20% of people with brain abscess. The famous triad of fever, headache and focal neurologic findings are highly suggestive of brain abscess. These symptoms are caused by a combination of increased intracranial pressure due to a space-occupying lesion (headache, vomiting, confusion ...

Seizures
An epileptic seizure, informally known as a seizure, is a period of symptoms due to abnormally excessive or synchronous neuronal activity in the brain. Outward effects vary from uncontrolled shaking movements involving much of the body with loss of consciousness ( tonic-clonic seizure), to shaking movements involving only part of the body with variable levels of consciousness ( focal seizure), to a subtle momentary loss of awareness ( absence seizure). Most of the time these episodes last less than two minutes and it takes some time to return to normal. Loss of bladder control may occur. Seizures may be provoked and unprovoked. Provoked seizures are due to a temporary event such as low blood sugar, alcohol withdrawal, abusing alcohol together with prescription medication, low blood sodium, fever, brain infection, or concussion. Unprovoked seizures occur without a known or fixable cause such that ongoing seizures are likely. Unprovoked seizures may be exacerbated by stress ...

Founded on May 11, 1751, by Benjamin Franklin and Dr. Thomas Bond, Pennsylvania Hospital is one of the earliest established public hospitals in the United States. It is also home to America's first surgical amphitheatre and its first medical library. The hospital's main building, dating to 1756, is a National Historic Landmark. History Pennsylvania Hospital was originally conceived in 1751 by Dr. Thomas Bond as an institution "for the reception and cure of the sick poor...free of charge. It was funded by "matching grant" to donations of the people of Philadelphia by a Bill which the House passed unanimously on 7 February 1750.
