Asperger syndrome (AS), also known as Asperger's syndrome, is a neurodevelopmental condition characterized by significant difficulties in social interaction and nonverbal communication combined with restricted and repetitive patterns of behavior and interests. The syndrome has been merged with other conditions into autism spectrum disorder (ASD) and is no longer considered a stand-alone diagnosis. It was considered to differ from other diagnoses that were merged into ASD by relatively unimpaired spoken language and intelligence.
Pervasive developmental disorder not otherwise specified (PDD-NOS) is a historic psychiatric diagnosis first defined in 1980 that has since been incorporated into autism spectrum disorder in the DSM-5 (2013).
Autism spectrum disorders (ASD) are neurodevelopmental disorders that begin in early childhood, persist throughout adulthood, and affect three crucial areas of development: communication, social interaction and restricted patterns of behavior. There are many conditions comorbid to autism spectrum disorders such as attention-deficit hyperactivity disorder and epilepsy.
High-functioning autism (HFA) was historically an autism classification where a person exhibits no intellectual disability, but may exhibit deficits in communication, emotion recognition and expression, and social interaction.
Nonverbal learning disability (NVLD) is proposed category of neurodevelopmental disorder characterized by core deficits in visual-spatial processing and a significant discrepancy between verbal and nonverbal intelligence. A review of papers found that proposed diagnostic criteria were inconsistent. Proposed additional diagnostic criteria include intact verbal intelligence, and deficits in the following: visuoconstruction abilities, speech prosody, fine-motor coordination, mathematical reasoning, visuospatial memory and social skills. NVLD is not recognised by the DSM-5 and is not clinically distinct from learning disorder.
The autism-spectrum quotient (AQ) is a questionnaire published in 2001 by Simon Baron-Cohen and his colleagues at the Autism Research Centre in Cambridge, UK. Consisting of fifty questions, it aims to investigate whether adults of average intelligence have symptoms of autism spectrum conditions. More recently, versions of the AQ for children and adolescents have also been published.
Child and adolescent psychiatry is a branch of psychiatry that focuses on the diagnosis, treatment, and prevention of mental disorders in children, adolescents, and their families. It investigates the biopsychosocial factors that influence the development and course of psychiatric disorders and treatment responses to various interventions. Child and adolescent psychiatrists primarily use psychotherapy and/or medication to treat mental disorders in the pediatric population.
Pathological demand avoidance (PDA) or extreme demand avoidance (EDA) is a proposed disorder and sub-type of autism spectrum disorder, defined by characteristics such as a greater than typical refusal to comply with requests or expectations and extreme efforts to avoid the social demand. Any expectation, even familiar, routine activities for highly desired activities, such as getting ready to leave home to visit a playground, can trigger avoidant behavior, and if the demand cannot be avoided, a panic attack or a meltdown may ensue.
Classic autism, also known as childhood autism, autistic disorder, (early) infantile autism, infantile psychosis, Kanner's autism,Kanner's syndrome, or (formerly) just autism, is a neurodevelopmental condition first described by Leo Kanner in 1943. It is characterized by atypical and impaired development in social interaction and communication as well as restricted, repetitive behaviors, activities, and interests. These symptoms first appear in early childhood and persist throughout life.
Several factors complicate the diagnosis of Asperger syndrome (AS), an autism spectrum disorder (ASD). Like other ASD forms, Asperger syndrome is characterized by impairment in social interaction accompanied by restricted and repetitive interests and behavior; it differs from the other ASDs by having no general delay in language or cognitive development. Problems in diagnosis include disagreement among diagnostic criteria, the controversy over the distinction between AS and other ASD forms or even whether AS exists as a separate syndrome, and over- and under-diagnosis for non-technical reasons. As with other ASD forms, early diagnosis is important, and differential diagnosis must consider several other conditions.
Childhood schizophrenia is similar in characteristics of schizophrenia that develops at a later age, but has an onset before the age of 13 years, and is more difficult to diagnose. Schizophrenia is characterized by positive symptoms that can include hallucinations, delusions, and disorganized speech; negative symptoms, such as blunted affect and avolition and apathy, and a number of cognitive impairments. Differential diagnosis is problematic since several other neurodevelopmental disorders, including autism spectrum disorder, language disorder, and attention deficit hyperactivity disorder, also have signs and symptoms similar to childhood-onset schizophrenia.
In psychiatry, stilted speech or pedantic speech is communication characterized by situationally inappropriate formality. This formality can be expressed both through abnormal prosody as well as speech content that is "inappropriately pompous, legalistic, philosophical, or quaint". Often, such speech can act as evidence for autism spectrum disorder (ASD) or a thought disorder, a common symptom in schizophrenia or schizoid personality disorder.
The Childhood Autism Spectrum Test, abbreviated as CAST and formerly titled the Childhood Asperger Syndrome Test, is a tool to screen for autism spectrum disorder in children aged 4–11 years, in a non-clinical setting. It is also called the Social and Communication Development Questionnaire.
Fred Robert Volkmar is a psychiatrist, psychologist, and the Irving B. Harris Professor of Child Psychiatry, Pediatrics, and Psychology at the Yale School of Medicine. From 2006 to 2014, he was the director of the Yale Child Study Center and the head of child psychiatry at Yale New Haven Hospital. Prior to these appointments, he was the director of the Autism Program at the Yale Child Study Center since 1983.
The history of autism spans over a century, autism has been subject to varying treatments, being pathologized or being viewed as a beneficial part of human neurodiversity. The understanding of autism has been shaped by cultural, scientific, and societal factors throughout history, and its perception and treatment change over time as scientific understanding of autism develops.
The Child Mania Rating Scales (CMRS) is a 21-item diagnostic screening measure designed to identify symptoms of mania in children and adolescents aged 9–17 using diagnostic criteria from the DSM-IV, developed by Pavuluri and colleagues. There is also a 10-item short form. The measure assesses the child's mood and behavior symptoms, asking parents or teachers to rate how often the symptoms have caused a problem for the youth in the past month. Clinical studies have found the CMRS to be reliable and valid when completed by parents in the assessment of children's bipolar symptoms. The CMRS also can differentiate cases of pediatric bipolar disorder from those with ADHD or no disorder, as well as delineating bipolar subtypes. A meta-analysis comparing the different rating scales available found that the CMRS was one of the best performing scales in terms of telling cases with bipolar disorder apart from other clinical diagnoses. The CMRS has also been found to provide a reliable and valid assessment of symptoms longitudinally over the course of treatment. The combination of showing good reliability and validity across multiple samples and clinical settings, along with being free and brief to score, make the CMRS a promising tool, especially since most other checklists available for youths do not assess manic symptoms.
The General Behavior Inventory (GBI) is a 73-question psychological self-report assessment tool designed by Richard Depue and colleagues to identify the presence and severity of manic and depressive moods in adults, as well as to assess for cyclothymia. It is one of the most widely used psychometric tests for measuring the severity of bipolar disorder and the fluctuation of symptoms over time. The GBI is intended to be administered for adult populations; however, it has been adapted into versions that allow for juvenile populations, as well as a short version that allows for it to be used as a screening test.
Sex and gender differences in autism exist regarding prevalence, presentation, and diagnosis.
Edward Ross Ritvo was an American psychiatrist known for his research on genetic components of autism. He was a professor emeritus of UCLA's Neuropsychiatric Institute.
