Karl Ludwig Kahlbaum
Karl Ludwig Kahlbaum (28 December 1828 – 15 April 1899) was a German psychiatrist. Life and career In 1855 he received his medical doctorate at Berlin, and subsequently worked as a physician at the mental asylum in Wehlau. For a period he was also a lecturer at the University of Königsberg (1863–66), and from 1867 was director of the mental hospital at Görlitz. He would remain at Görlitz for the remainder of his life. As a psychiatrist, Kahlbaum realized that attempting to group mental disorders based on similarities of outward symptoms was futile, and in his work tried to develop a classification system that grouped mental diseases according to their course and outcome. He is remembered for research done at Görlitz with his associate Ewald Hecker (1843–1909) involving studies of young psychotic patients. In their analyses of mental disorders, Kahlbaum and Hecker introduced a classification system that used descriptive terms such as dysthymia, cyclothymia, catatonia, ...

Drezdenko
Drezdenko (; german: Driesen) is a town in western Poland, in Lubusz Voivodeship, in Strzelce-Drezdenko County. As of December 2021, the town has a population of 9,804. History The area was a site of a border fort of the medieval Polish state. During the reign of Bolesław III Wrymouth it was raised to the rank of a castellany. During the period of feudal fragmentation of Poland it was initially part of the Duchy of Greater Poland and then subject of fighting between the Duchy and the Margraviate of Brandenburg, which took control of it after 1296. It was sold by the Brandenburgians to the Monastic Order of the Teutonic Knights in 1317, under the authority of the knights Burkhard and Heinrich von der Osten. However, in 1365 it became part of the Kingdom of Poland, during the rule of King Casimir III the Great, to be lost again to the Teutonic Knights in 1408. The town was neglected by the Teutonic Knights, the castle burned down, and parts of the town walls collapsed. In 1455, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraphrenia
Paraphrenia is a mental disorder characterized by an organized system of paranoid delusions with or without hallucinations (the positive symptoms of schizophrenia) and without deterioration of intellect or personality (its negative symptom).Almeida, O.

American Psychiatric Association
The American Psychiatric Association (APA) is the main professional organization of psychiatrists and trainee psychiatrists in the United States, and the largest psychiatric organization in the world. It has more than 37,000 members are involved in psychiatric practice, research, and academia representing a diverse population of patients in more than 100 countries. The association publishes various journals and pamphlets, as well as the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM). The DSM codifies psychiatric conditions and is used mostly in the United States as a guide for diagnosing mental disorders. The organization has its headquarters in Washington, DC.

Stereotypy
A stereotypy (, or ) is a repetitive or ritualistic movement, posture, or utterance. Stereotypies may be simple movements such as body rocking, or complex, such as self-caressing, crossing and uncrossing of legs, and marching in place. They are found especially in people with autism spectrum disorders and visually impaired children, and are also found in intellectual disabilities, tardive dyskinesia and stereotypic movement disorder, yet may also be encountered in neurotypical individuals as well. Studies have shown stereotypies associated with some types of schizophrenia. Frontotemporal dementia is also a common neurological cause of repetitive behaviors and stereotypies. Several causes have been hypothesized for stereotypy, and several treatment options are available. Stereotypy is sometimes called ''stimming'' in autism, under the hypothesis that it self-stimulates one or more senses. Among people with frontotemporal lobar degeneration, more than half (60%) had stereotypies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catalepsy
Catalepsy (from Ancient Greek , , "seizing, grasping") is a nervous condition characterized by muscular rigidity and fixity of posture regardless of external stimuli, as well as decreased sensitivity to pain. Signs and symptoms Symptoms include a rigid body, rigid limbs, limbs staying in same position when moved (waxy flexibility), no response, loss of muscle control, and slowing down of bodily functions, such as breathing. Causes Catalepsy is a symptom of certain nervous disorders or conditions such as Parkinson's disease and epilepsy. It is also a characteristic symptom of cocaine withdrawal, as well as one of the features of catatonia. It can be caused by schizophrenia treatment with anti-psychotics, such as haloperidol, and by the anesthetic ketamine. Protein kinase A has been suggested as a mediator of cataleptic behavior. Unsuggested waxy catalepsy, sometimes accompanied by spontaneous anesthesia, is seen as an indicator of hypnotic trance. Suggested or induced rigi ...

Adolf Meyer (psychiatrist)
Adolf Meyer (September 13, 1866 – March 17, 1950) was a Swiss-born psychiatrist who rose to prominence as the first psychiatrist-in-chief of the Johns Hopkins Hospital (1910-1941). He was president of the American Psychiatric Association in 1927–28 and was one of the most influential figures in psychiatry in the first half of the twentieth century. His focus on collecting detailed case histories on patients was one of the most prominent of his contributions. He oversaw the building and development of the Henry Phipps Psychiatric Clinic at Johns Hopkins Hospital, opened in April 1913, making sure it was suitable for scientific research, training and treatment. Meyer's work at the Phipps Clinic is possibly the most significant aspect of his career. Meyer's main theoretical contribution was his idea of ergasiology (a term he derived from the Greek for "working" and "doing") to describe a psychobiology. This brought together all the biological, social and psychological facto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dementia Praecox
Dementia praecox (meaning a "premature dementia" or "precocious madness") is a disused psychiatric diagnosis that originally designated a chronic, deteriorating psychotic disorder characterized by rapid cognitive disintegration, usually beginning in the late teens or early adulthood. Over the years, the term ''dementia praecox'' was gradually replaced by ''schizophrenia'', which remains in current diagnostic use. The term ''dementia praecox'' was first used in 1891 by Arnold Pick (1851–1924), a professor of psychiatry at Charles University in Prague. In a brief clinical report, he described a person with a psychotic disorder resembling "hebephrenia" (schizophrenia). German psychiatrist Emil Kraepelin (1856–1926) popularised the term ''dementia praecox'' in his first detailed textbook descriptions of a condition that eventually became a different disease concept later relabeled as ''schizophrenia''. Kraepelin reduced the complex psychiatric taxonomies of the nineteenth centur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emil Kraepelin
Emil Wilhelm Georg Magnus Kraepelin (; ; 15 February 1856 – 7 October 1926) was a German psychiatrist. H. J. Eysenck's ''Encyclopedia of Psychology'' identifies him as the founder of modern scientific psychiatry, psychopharmacology and psychiatric genetics. Kraepelin believed the chief origin of psychiatric disease to be biological and genetic malfunction. His theories dominated psychiatry at the start of the 20th century and, despite the later psychodynamic influence of Sigmund Freud and his disciples, enjoyed a revival at century's end. While he proclaimed his own high clinical standards of gathering information "by means of expert analysis of individual cases", he also drew on reported observations of officials not trained in psychiatry. His textbooks do not contain detailed case histories of individuals but mosaic-like compilations of typical statements and behaviors from patients with a specific diagnosis. He has been described as "a scientific manager" and "a politi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychosis
Psychosis is a condition of the mind that results in difficulties determining what is real and what is not real. Symptoms may include delusions and hallucinations, among other features. Additional symptoms are incoherent speech and behavior that is inappropriate for a given situation. There may also be sleep problems, social withdrawal, lack of motivation, and difficulties carrying out daily activities. Psychosis can have serious adverse outcomes. As with many psychiatric phenomena, psychosis has several different causes. These include mental illness, such as schizophrenia or schizoaffective disorder, bipolar disorder, sensory deprivation and in rare cases, major depression (psychotic depression). Other causes include: trauma, sleep deprivation, some medical conditions, certain medications, and drugs such as cannabis, hallucinogens, and stimulants. One type, known as postpartum psychosis, can occur after giving birth. The neurotransmitter dopamine is believed to p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
