Pervasive Developmental Disorder
The diagnostic category pervasive developmental disorders (PDD), as opposed to specific developmental disorders (SDD), is a group of disorders characterized by delays in the development of multiple basic functions including socialization and communication. The pervasive developmental disorders include autism, Asperger syndrome, pervasive developmental disorder not otherwise specified (PDD-NOS, i.e., all autism spectrum disorders SD, childhood disintegrative disorder (CDD), overactive disorder associated with mental retardation and stereotyped movements, and Rett syndrome. The first four of these disorders are commonly called the autism spectrum disorders; the last disorder is much rarer, and is sometimes placed in the autism spectrum and sometimes not. The terminology PDD and ASD is often used interchangeably and varies depending on location. The two have overlapping definitions but are defined differently by the Diagnostic and Statistical Manual of Mental Disorders, 5t ...

Psychiatry
Psychiatry is the 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 case history and mental status examination. Physical examinations and psychological tests may be conducted. On occasion, neuroimaging or other 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-organized the larger categories of various diseases and expanded up ...

DSM-V
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 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. The DSM-5 is the only DSM to use an Arabic numeral instead of a Roman numeral in its title, as well as the only living document version of a DSM. The DSM-5 is not a major revision of the DSM-IV-TR but there are significant differences. Changes in the DSM-5 include the reconceptualization of Asperger syndrome from a distinct disorder to an autism spectrum disorder; the elimination of subtypes of schizophrenia; the deletion of the "bereavement exclusion" for ...

Special Education
Special education (known as special-needs education, aided education, exceptional education, alternative provision, exceptional student education, special ed., SDC, or SPED) is the practice of educating students in a way that accommodates their individual differences, disabilities, and special needs. This involves the individually planned and systematically monitored arrangement of teaching procedures, adapted equipment and materials, and accessible settings. These interventions are designed to help individuals with special needs achieve a higher level of personal self-sufficiency and success in school and in their community, which may not be available if the student were only given access to a typical classroom education. Special education aims to provide accommodated education for disabled students such as learning disabilities, learning difficulties (such as dyslexia), communication disorders, emotional and behavioral disorders, physical disabilities (such as oste ...

Multisystem Developmental Disorder
Multisystem developmental disorder (MSDD) is a term used by Stanley Greenspan to describe children under age 3 who exhibit signs of impaired communication as in autism, but with strong emotional attachments atypical of autism. It is described in the DC:0-3R manual as an optional diagnosis for children under two years of age. Other uses of the term The term ''multisystem developmental disorder'' has also been used to describe various developmental disorders. These include: *Alagille syndrome, an autosomal dominant disorder with a wide range of features and manifestations. Its five most significant features are chronic cholestasis, a condition where bile cannot flow from the liver to the duodenum, occurring in 95% of cases; heart abnormalities (over 90%); butterfly vertebrae; posterior embryotoxon and a distinctive face (prominent forehead, deep-set eyes, and a pointed chin). * Rubinstein-Taybi syndrome, a syndrome characterized by broad thumbs, facial abnormalities, and big toes al ...

Multiple Complex Developmental Disorder
Multiple complex developmental disorder (MCDD) is a research category, proposed to involve several neurological and psychological symptoms where at least some symptoms are first noticed during early childhood and persist throughout life. It was originally suggested to be a subtype of autistic spectrum disorders (PDD) with co-morbid schizophrenia or another psychotic disorder; however, there is some controversy that not everyone with MCDD meets criteria for both PDD and psychosis. The term ''multiplex developmental disorder'' was coined by Donald J. Cohen in 1986. Diagnostic criteria The current diagnostic criteria for MCDD are a matter of debate due to it not being in the DSM-V or ICD-10. Various websites contain various diagnostic criteria. At least three of the following categories should be present. Co-occurring clusters of symptoms must also not be better explained by being symptoms of another disorder such as experiencing mood swings due to autism, cognitive difficultie ...

Infantile Neuroaxonal Dystrophy
Infantile neuroaxonal dystrophy is a rare pervasive developmental disorder that primarily affects the nervous system. Individuals with infantile neuroaxonal dystrophy typically do not have any symptoms at birth, but between the ages of about 6 and 18 months they begin to experience delays in acquiring new motor and intellectual skills, such as crawling or beginning to speak. Eventually they lose previously acquired skills. Cause This condition is inherited in an autosomal recessive pattern, which means two copies of the gene (''PLA2G6'') in each cell are altered. Most often, the parents of an individual with an autosomal recessive disorder each carry one copy of the altered gene but do not show signs and symptoms of the disorder. Pathophysiology Mutations in the ''PLA2G6'' gene have been identified in most individuals with infantile neuroaxonal dystrophy. The ''PLA2G6'' gene provides instructions for making an enzyme called an A2 phospholipase. This enzyme family is involved i ...

Diagnostic And Statistical Manual
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 pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Childhood Disintegrative Disorder
Childhood disintegrative disorder (CDD), also known as Heller's syndrome and disintegrative psychosis, is a rare condition characterized by late onset of developmental delays—or severe and sudden reversals—in language, social function, and motor skills. Researchers have not been successful in finding a cause for the disorder. CDD has some similarity to autism and is sometimes considered a low-functioning form of it. In May 2013, CDD, along with other sub-types of PDD ( Asperger's syndrome, autism, and PDD-NOS), was fused into a single diagnostic term called "autism spectrum disorder" under the new DSM-5 manual. CDD was originally described by Austrian educator Theodor Heller (1869–1938) in 1908, 35 years before Leo Kanner and Hans Asperger described autism. Heller had previously used the name ''dementia infantilis'' for the syndrome. An apparent period of fairly normal development is often noted before a regression in skills or a series of regressions in skills. The ag ...

Pervasive Developmental Disorder Not Otherwise Specified
A pervasive developmental disorder not otherwise specified (Including atypical autism) (PDD-NOS) is one of four disorders which were collapsed into the diagnosis of autism spectrum disorder in the DSM-5 and also was one of the five disorders classified as a pervasive developmental disorder (PDD) in the DSM-IV. According to the DSM-4, PDD-NOS is a diagnosis that is used for "severe or pervasive impairment in the development of reciprocal social interaction and/or verbal and nonverbal communication skills, or when stereotyped behavior, interests, and/or activities are present, but the criteria are not met for a specific PDD" or for several other disorders. PDD-NOS includes atypical autism, because the criteria for autistic disorder are not met, for instance because of late age of onset, atypical symptomatology, or subthreshold symptomatology, or all of these. Even though PDD-NOS is considered milder than typical autism, this is not always true. While some characteristics may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Childhood Intervention
Early childhood intervention (ECI) is a support and educational system for very young children (aged birth to six years) who have been victims of, or who are at high risk for child abuse and/or neglect as well as children who have developmental delays or disabilities. Some states and regions have chosen to focus these services on children with developmental disabilities or delays, but Early Childhood Intervention is not limited to children with these disabilities. The mission of early childhood intervention is to assure that families who have at-risk children in this age range receive resources and supports that assist them in maximizing their child's physical, cognitive, and social/emotional development while respecting the diversity of families and communities. Definition Early intervention is a system of coordinated services that promotes the child's age-appropriate growth and development and supports families during the critical early years. In the United States, some early i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
