Spectrum Disorder
A spectrum disorder is a Disease#Disorder, disorder that includes a range of linked conditions, sometimes also extending to include singular symptoms and trait theory, traits. The different elements of a spectrum either have a similar appearance or are thought to be caused by the same underlying mechanism. In either case, a spectrum approach is taken because there appears to be "not a unitary disorder but rather a syndrome composed of subgroups". The spectrum may represent a range of severity, comprising relatively "severe" mental disorders through to relatively "mild and nonclinical Cognitive deficit, deficits". The term "spectrum disorder" is heavily used in psychiatry and psychology, but has also seen adoption in other areas of medicine, for example hypermobility spectrum disorder and neuromyelitis optica spectrum disorder. In some cases, a spectrum approach joins conditions that were previously considered separately. A notable example of this trend is the autism spectrum, where ...

Neuromyelitis Optica Spectrum Disorder
Neuromyelitis optica spectrum disorders (NMOSD) are a spectrum of autoimmune diseases characterized by acute inflammation of the optic nerve (optic neuritis, ON) and the spinal cord (myelitis).Banerjee S, Butcher R.

Available from: https://www.ncbi.nlm.nih.gov/books/NBK571350/ Episodes of ON and myelitis can be simultaneous or successive. A relapsing disease course is common, especially in untreated patients. * Neuromyelitis optica (NMO) is a particular disease within the NMOSD spectrum. It is characterised by optic neuritis and longitudinally extensive myelitis. In more than 80% of NMO cases, the cause is immunoglobulin G Autoantibody, autoantibodies to aquaporin 4 (anti-AQP4 diseases, anti-AQP4), the most abundant Aquaporin, water channel protein in the central nervous system. * Less common diseases with other manifestati ...

Disease
A disease is a particular abnormal condition that adversely affects the structure or function (biology), function of all or part of an organism and is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergy, allergies, and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, Abnormality (behavior), dysfunction, distress (medicine), distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injury in humans, injuries, disability, disabilities, Disorder (medicine) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychiatry
Psychiatry is the medical specialty devoted to the diagnosis, treatment, and prevention of deleterious mental disorder, mental conditions. These include matters related to cognition, perceptions, Mood (psychology), mood, emotion, and behavior. Initial psychiatric assessment of a person begins with creating a Medical history, case history and conducting a mental status examination. Laboratory tests, physical examinations, and psychological tests may be conducted. On occasion, neuroimaging or 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) was published in May 2013. Treatment may include psychotropics (psychiatric medicines), psychotherapy, su ...

DSM-III
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. It is an internationally accepted manual on the diagnosis and treatment of mental disorders, though it may be used in conjunction with other documents. Other commonly used principal guides of psychiatry include the International Classification of Diseases (ICD), Chinese Classification of Mental Disorders (CCMD), and the '' Psychodynamic Diagnostic Manual''. However, not all providers rely on the DSM-5 as a guide, since the ICD's mental disorder diagnoses are used around the world, and scientific studies often measure changes in symptom scale scores rather than changes in DSM-5 criteria to determine the real-world effects of mental health interventions.

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 political ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Schizothymic
Schizothymia is a temperament related to schizophrenia in a way analogous to cyclothymia's relationship with bipolar disorder. Schizothymia was proposed by German psychiatrist Ernst Kretschmer in the early 20th-century when examining body types of schizophrenic patients. Schizothymia is defined by reduced affect display, a high degree of introversion, limited social cognition, and withdrawing from social relations generally. Nevertheless, individuals with such personality traits may achieve relatively affable social relations and a measure of affectivity situationally. As a kind of temperament, schizothymic personality traits are thought to be innate rather than the result of socialization or a lack thereof (Nature versus Nurture).

Schizophrenic
Schizophrenia () is a mental disorder characterized variously by hallucinations (typically, Auditory hallucination#Schizophrenia, hearing voices), delusions, thought disorder, disorganized thinking and behavior, and Reduced affect display, flat or inappropriate affect. Symptoms Prodrome, develop gradually and typically begin during young adulthood and rarely resolve. There is no objective diagnostic test; diagnosis is based on observed behavior, a psychiatric history that includes the person's reported experiences, and reports of others familiar with the person. For a diagnosis of schizophrenia, the described symptoms need to have been present for at least six months (according to the DSM-5) or one month (according to the ICD-11). Many people with schizophrenia have other mental disorders, especially mood disorder, mood, anxiety disorder, anxiety, and substance use disorders, substance use disorders, as well as obsessive–compulsive disorder (OCD).

Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of optical instruments, instruments that use or Photodetector, detect it. Optics usually describes the behaviour of visible light, visible, ultraviolet, and infrared light. Light is a type of electromagnetic radiation, and other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the Classical electromagnetism, classical electromagnetic description of light, however complete electromagnetic descriptions of light are often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of Ray (optics), rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
