Hebephrenia
Disorganized schizophrenia, or hebephrenia, is an obsolete term for a subtype of schizophrenia. It is no longer recognized as a separate condition, following the publication of the ''Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition'' (''DSM-5'') in 2013, which dropped the concept of subtypes of schizophrenia, and global adoption of the eleventh revision of the ''International Classification of Diseases'' (''ICD-11'') in 2022. It was originally proposed by the German psychiatrist Ewald Hecker in the 1870s. Disorganized schizophrenia was classified up to ''ICD-10'' 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 a ...

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 the term ''schizophrenia'', which initially had a meaning that included what is today considered the autism spectrum. The term ''dementia praecox'' was first used by German psychiatrist Heinrich Schüle in 1880. It was also used in 1891 by Arnold Pick (1851–1924), a professor of psychiatry at Karl-Ferdinands-Universität, Charles University in Prague. In a brief clinical report, he described a person with a psychotic disorder resembling "hebephrenia" (an adolescent-onset psychotic condition). German psychiatrist Emil Kraepelin (1856–1926) popularised the term ''dementia praecox'' in his first detailed textbook descriptions ...

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 ...

Paranoid Schizophrenia
Schizophrenia () is a mental disorder characterized variously by hallucinations (typically, hearing voices), delusions, disorganized thinking and behavior, and flat or inappropriate affect. Symptoms 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, anxiety, and substance use disorders, as well as obsessive–compulsive disorder (OCD). About 0.3% to 0.7% of people are diagnosed with schizophrenia during their lifetime. In 2017, there were an estimated 1.1 million new cases and in 2022 a total ...

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] |

ICD-10
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. Work on ICD-10 began in 1983, was endorsed by the Forty-third World Health Assembly in 1990, and came into effect in member states on January 1, 1993. ICD-10 was replaced by ICD-11 on January 1, 2022. While WHO manages and publishes the base version of the ICD, several member states have modified it to better suit their needs. In the base classification, the code set allows for more than 14,000 different codes and permits the tracking of many new diagnoses compared to the preceding ICD-9. Through the use of optional sub-classifications, ICD-10 allows for specificity regarding the cause, manifestation, location, severity, and type of injury or disease. The adapted versions may differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Affect (psychology)
Affect, in psychology, is the underlying experience of feeling, emotion, attachment theory, attachment, or Mood (psychology), mood. It encompasses a wide range of emotional states and can be positive (e.g., happiness, joy, excitement) or negative (e.g., sadness, anger, fear, disgust). Affect is a fundamental aspect of human experience and plays a central role in many psychological theories and studies. It can be understood as a combination of three components: emotion, mood (enduring, less intense emotional states that are not necessarily tied to a specific event), and affectivity (an individual's overall disposition or temperament, which can be characterized as having a generally positive or negative affect). In psychology, the term ''affect'' is often used interchangeably with several related terms and concepts, though each term may have slightly different nuances. These terms encompass: emotion, feeling, mood, emotional state, sentiment, affective state, emotional response, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DSM 5
The ''Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition'' (DSM-5), is the 2013 update to the ''Diagnostic and Statistical Manual of Mental Disorders'', the taxonomic and diagnostic tool published by the American Psychiatric Association (APA). In 2022, a revised version (DSM-5-TR) was published. In the United States, the DSM serves as the principal authority for psychiatric diagnoses. Treatment recommendations, as well as payment by health care providers, are often determined by DSM classifications, so the appearance of a new version has practical importance. However, some providers instead rely on the International Statistical Classification of Diseases and Related Health Problems (ICD), 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. The DSM-5 is the only DSM to use an Arabic numeral instead of a Roman numeral in its title, as well a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communication Deviance
Communication deviance (CD) occurs when a speaker fails to effectively communicate and convey meaning to their listeners with confusing speech patterns or illogical patterns. These disturbances can range from vague linguistic references, contradictory statements to more encompassing non-verbal problems at the level of turn-taking. The term was originally introduced by Lyman Wynne and Margaret Singer in 1963 to describe a communication style found among parents who had children with schizophrenia. According to Wynne, people are able to focus their attention and identify meaning from external stimuli beginning with their interactions, particularly with their parents, during their early years of life. In family communication, deviance is present in the way members acknowledge or affirm one another as well as in task performance. A recent meta-analysis reported that communication deviance is highly prevalent in parents of patients diagnosed with schizophrenia and adoption studies ha ...

Catatonia
Catatonia is a complex syndrome most commonly seen in people with underlying mood disorders, such as major depressive disorder, or psychotic disorders, such as schizophrenia. People with catatonia exhibit abnormal movement and behaviors, which vary from person to person and may fluctuate in intensity within a single episode. People with catatonia appear withdrawn, meaning that they do not interact with the outside world and have difficulty processing information. They may be nearly motionless for days on end or perform repetitive purposeless movements. People may exhibit very different sets of behaviors and still be diagnosed with catatonia. Treatment with benzodiazepines or ECT are most effective and lead to remission of symptoms in most cases. There are different subtypes of catatonia, which represent groups of symptoms that commonly occur together. These include stuporous/akinetic catatonia, excited catatonia, malignant catatonia, and periodic catatonia. Catatonia has h ...

Avolition
Avolition or amotivation, 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 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. It is a disorder of diminished motivation. Psychopathology People with avolition often want to complete certain tasks but lack the ability to initiate behaviors 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 (NI ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
