Hebephrenia
Disorganized schizophrenia, or hebephrenia, was a subtype of schizophrenia prior to 2013. Subtypes of schizophrenia were no longer recognized as separate conditions in the '' DSM 5'', published in 2013. The disorder is no longer listed in the 11th revision of the International Classification of Diseases (ICD-11). Disorganized schizophrenia was classified within ICD-10 the existing classification, in practice, until January 1, 2022, as a mental and behavioural disorder, because the classification was thought to be an extreme expression of the ''disorganization syndrome'' that has been hypothesized to be one aspect of a three-factor model of symptoms in schizophrenia, the other factors being ''reality distortion'' (involving delusions and hallucinations) and ''psychomotor poverty'' (lack of speech, lack of spontaneous movement and various aspects of blunting of emotion). Presentation The condition is also known as hebephrenia, named after the Greek term for "adolescence" – '' ... [...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] |
Ewald Hecker
Ewald Hecker (20 October 1843, Halle – 11 January 1909, Wiesbaden) was a German psychiatrist who was an important figure in the early days of modern psychiatry. He is known for research done with his mentor, psychiatrist Karl Ludwig Kahlbaum (1828-1899). In the early 1870s Kahlbaum and Hecker did a series of studies on young psychotic patients at Kahlbaum's clinic in Görlitz, Prussia. Together they provided clinical analyses of the mentally ill, and arranged their disorders into specific, descriptive categories. It was during this period that Hecker developed the concepts of hebephrenia and cyclothymia. He described hebephrenia as a disorder that begins in adolescence with erratic behaviour followed by a rapid decline of all mental functions, and cyclothymia as a cyclical mood disorder. The pioneering research of Kahlbaum and Hecker proposed the existence of more than one discrete psychiatric disorder, which contrasted with the concept of "unitary psychosis" that maintai ...

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] |
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] |
Prognosis
Prognosis (Greek: πρόγνωσις "fore-knowing, foreseeing") is a medical term for predicting the likely or expected development of a disease, including whether the signs and symptoms will improve or worsen (and how quickly) or remain stable over time; expectations of quality of life, such as the ability to carry out daily activities; the potential for complications and associated health issues; and the likelihood of survival (including life expectancy). A prognosis is made on the basis of the normal course of the diagnosed disease, the individual's physical and mental condition, the available treatments, and additional factors. A complete prognosis includes the expected duration, function, and description of the course of the disease, such as progressive decline, intermittent crisis, or sudden, unpredictable crisis. When applied to large statistical populations, prognostic estimates can be very accurate: for example the statement "45% of patients with severe septic shock w ...

Avolition
Avolition, as a symptom of various forms of psychopathology, is the decrease in the ability to initiate and persist in self-directed purposeful activities. Such activities that appear to be neglected usually include routine activities, including hobbies, going to work and/or school, and most notably, engaging in social activities. A person experiencing avolition may stay at home for long periods of time, rather than seeking out work or peer relations. Psychopathology People with avolition often want to complete certain tasks but lack the ability to initiate behaviours necessary to complete them. Avolition is most commonly seen as a symptom of some other disorder, but might be considered a primary clinical disturbance of itself (or as a coexisting second disorder) related to disorders of diminished motivation. In 2006, avolition was identified as a negative symptom of schizophrenia by the National Institute of Mental Health (NIMH), and has been observed in patients with bipolar d ...

Anhedonia
Anhedonia is a diverse array of deficits in hedonic function, including reduced motivation or ability to experience pleasure. While earlier definitions emphasized the inability to experience pleasure, anhedonia is currently used by researchers to refer to reduced motivation, reduced anticipatory pleasure (wanting), reduced consummatory pleasure (liking), and deficits in reinforcement learning. In the ''Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition'' (DSM-5), anhedonia is a component of depressive disorders, substance-related disorders, psychotic disorders, and personality disorders, where it is defined by either a reduced ability to experience pleasure, or a diminished interest in engaging in pleasurable activities. While the ''International Statistical Classification of Diseases and Related Health Problems, Tenth Revision'' (ICD-10) does not explicitly mention anhedonia, the depressive symptom analogous to anhedonia as described in the DSM-5 is a loss of i ...

Hypochondriasis
Hypochondriasis or hypochondria is a condition in which a person is excessively and unduly worried about having a serious illness. An old concept, the meaning of hypochondria has repeatedly changed. It has been claimed that this debilitating condition results from an inaccurate perception of the condition of body or mind despite the absence of an actual medical diagnosis. An individual with hypochondriasis is known as a hypochondriac. Hypochondriacs become unduly alarmed about any physical or psychological symptoms they detect, no matter how minor the symptom may be, and are convinced that they have, or are about to be diagnosed with, a serious illness. Often, hypochondria persists even after a physician has evaluated a person and reassured them that their concerns about symptoms do not have an underlying medical basis or, if there is a medical illness, their concerns are far in excess of what is appropriate for the level of disease. It is also referred to hypochondriaism which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formal Thought Disorder
A thought disorder (TD) is any disturbance in cognition that adversely affects language and thought content, and thereby communication. A variety of thought disorders were said to be characteristic of people with schizophrenia. A content-thought disorder is typically characterized by the experience of multiple delusional fragments. The term ''thought disorder'' is often used to refer to a formal thought disorder. A formal thought disorder (FTD) is a disruption of the form or structure of thought. Formal thought disorder, also known as disorganized thinking, results in disorganized speech and is recognized as a major feature of schizophrenia and other psychosis, psychoses. FTD is also associated with conditions including mood disorders, dementia, mania, and neurological diseases. Disorganized speech leads to an inference of disorganized thoughts. Types of thought disorders include Derailment (thought disorder), derailment, pressured speech, poverty of speech, tangentiality, verbi ...

Delusion
A delusion is a false fixed belief that is not amenable to change in light of conflicting evidence. As a pathology, it is distinct from a belief based on false or incomplete information, confabulation, dogma, illusion, hallucination, or some other misleading effects of perception, as individuals with those beliefs ''are'' able to change or readjust their beliefs upon reviewing the evidence. However: "The distinction between a delusion and a strongly held idea is sometimes difficult to make and depends in part on the degree of conviction with which the belief is held despite clear or reasonable contradictory evidence regarding its veracity." Delusions have been found to occur in the context of many pathological states (both general physical and mental) and are of particular diagnostic importance in psychosis, psychotic disorders including schizophrenia, paraphrenia, Mania, manic episodes of bipolar disorder, and psychotic depression. Types Delusions are categorized into four d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catatonia
Catatonia is a complex neuropsychiatric behavioral syndrome that is characterized by abnormal movements, immobility, abnormal behaviors, and withdrawal. The onset of catatonia can be acute or subtle and symptoms can wax, wane, or change during episodes. There are several subtypes of catatonia: akinetic catatonia, excited catatonia, malignant catatonia, delirious mania, and self-injurious behaviors in autism. Although catatonia has historically been related to schizophrenia (catatonic schizophrenia), catatonia is most often seen in mood disorders. It is now known that catatonic symptoms are nonspecific and may be observed in other mental, neurological, and medical conditions. Catatonia is not a stand-alone diagnosis (although some experts disagree), and the term is used to describe a feature of the underlying disorder. Recognizing and treating catatonia is very important as failure to do so can lead to poor outcomes and can be potentially fatal. Treatment with benzodiazepines o ...

Psychiatrist
A psychiatrist is a physician who specializes in psychiatry, the branch of medicine devoted to the diagnosis, prevention, study, and treatment of mental disorders. Psychiatrists are physicians and evaluate patients to determine whether their symptoms are the result of a physical illness, a combination of physical and mental ailments or strictly mental issues. Sometimes a psychiatrist works within a multi-disciplinary team, which may comprise Clinical psychology, clinical psychologists, Social work, social workers, Occupational therapist, occupational therapists, and Nursing, nursing staff. Psychiatrists have broad training in a Biopsychosocial model, biopsychosocial approach to the assessment and management of mental illness. As part of the clinical assessment process, psychiatrists may employ a mental status examination; a physical examination; brain imaging such as a computerized tomography, magnetic resonance imaging, or positron emission tomography scan; and blood testing.
