Childhood Disintegrative Disorder
Childhood disintegrative disorder (CDD), also known as Heller syndrome and disintegrative psychosis, is a rare condition characterized by late onset of developmental delays—or severe and sudden reversals—in language (receptive and expressive), social engagement, bowel and bladder, play and motor skills. Researchers have not been successful in finding a cause for the disorder. CDD has some similarities to autism and is sometimes considered a low-functioning form of it. In May 2013, CDD was one of several sub-types of pervasive developmental disorder (PDD)—including Asperger's syndrome, classic autism, and pervasive developmental disorder not otherwise specified—that was subsumed into a single diagnostic term called "autism spectrum disorder" in the 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 infantil ... [...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 ...

Low-functioning Autism
Classic autism—also known as childhood autism, autistic disorder, or Kanner's syndrome—is a formerly diagnosed neurodevelopmental disorder first described by Leo Kanner in 1943. It is characterized by atypical and impaired development in social interaction and communication as well as restricted and repetitive behaviors, activities, and interests. These symptoms first appear in early childhood and persist throughout life. Classic autism was last recognized as a diagnosis in the DSM-IV and ICD-10, and has been superseded by autism-spectrum disorder in the DSM-5 (2013) and ICD-11 (2022). Globally, classic autism was estimated to affect 24.8 million people . Autism is likely caused by a combination of genetic and environmental factors, with genetic factors thought to heavily predominate. Certain proposed environmental causes of autism have been met with controversy, such as the vaccine hypothesis that, although disproved, has negatively impacted vaccination rates among c ...

Speech Perception
Speech perception is the process by which the sounds of language are heard, interpreted, and understood. The study of speech perception is closely linked to the fields of phonology and phonetics in linguistics and cognitive psychology and perception in psychology. Research in speech perception seeks to understand how human listeners recognize speech sounds and use this information to understand spoken language. Speech perception research has applications in building Speech recognition, computer systems that can recognize speech, in improving speech recognition for hearing- and language-impaired listeners, and in foreign-language teaching. The process of perceiving speech begins at the level of the sound signal and the process of audition. (For a complete description of the process of audition see Hearing (sense), Hearing.) After processing the initial auditory signal, speech sounds are further processed to extract acoustic cues and phonetic information. This speech information can ...

Listening
Listening is the act of attention, paying attention to sounds. It includes listening to the sounds of Natural environment, nature, listening to music, and perhaps most importantly, Interpersonal communication, interpersonal listening, i.e. listening to other human beings. When listening to another person, one Hearing, hears what they are Speech, saying and tries to understand what it means. Interpersonal listening involves complex affective, Cognition, cognitive, and behavioral processes. Affective processes include the motivation to listen to others; cognitive processes include Attention, attending to, understanding, receiving, and interpreting content and relational messages; and behavioral processes include responding to others with verbal and Nonverbal communication, nonverbal feedback. Interpersonal listening is a skill for Problem solving, resolving problems. Poor interpersonal listening can lead to misinterpretations, thus causing conflict or dispute. Poor listening can b ...

Speech Production
Speech production is the process by which thoughts are translated into speech. This includes the selection of words, the organization of relevant Grammar, grammatical forms, and then the articulation of the resulting sounds by the motor system using the vocal apparatus. Speech production can be spontaneous such as when a person creates the words of a conversation, reactive such as when they name a picture or reading (process), read aloud a writing, written word, or imitative, such as in speech repetition. Speech production is not the same as language production since language can also be produced manually by sign language, signs. In ordinary fluent conversation people pronounce roughly four syllables, ten or twelve phonemes and two to three words out of their vocabulary (that can contain 10 to 100 thousand words) each second. Errors in speech production are relatively rare occurring at a rate of about once in every 900 words in spontaneous speech. Words that are Frequency list, com ...

Hallucination
A hallucination is a perception in the absence of an external stimulus that has the compelling sense of reality. They are distinguishable from several related phenomena, such as dreaming ( REM sleep), which does not involve wakefulness; pseudohallucination, which does not mimic real perception, and is accurately perceived as unreal; illusion, which involves distorted or misinterpreted real perception; and mental imagery, which does not mimic real perception, and is under voluntary control. Hallucinations also differ from " delusional perceptions", in which a correctly sensed and interpreted stimulus (i.e., a real perception) is given some additional significance. Hallucinations can occur in any sensory modality— visual, auditory, olfactory, gustatory, tactile, proprioceptive, equilibrioceptive, nociceptive, thermoceptive and chronoceptive. Hallucinations are referred to as multimodal if multiple sensory modalities occur. A mild form of hallucination is known as ...

Prodrome
In medicine, a prodrome is an early sign or symptom (or set of signs and symptoms, referred to as prodromal symptoms) that often indicates the onset of a disease before more diagnostically specific signs and symptoms develop. More specifically, it refers to the period between the first recognition of a disease's symptom until it reaches its more severe form. It is derived from the Greek word ''prodromos'', meaning "running before". Prodromes may be non-specific symptoms or, in a few instances, may clearly indicate a particular disease, such as the prodromal migraine aura. For example, fever, malaise, headache and lack of appetite frequently occur in the prodrome of many infective disorders. A prodrome can be the early precursor to an episode of a chronic neurological disorder such as a migraine headache or an epileptic seizure, where prodrome symptoms may include euphoria or other changes in mood, insomnia, abdominal sensations, disorientation, aphasia, or photosensitivity.

Hans Asperger
Johann Friedrich Karl Asperger (, ; 18 February 1906 – 21 October 1980) was an Austrian physician. Noted for his early studies on atypical neurology, specifically in children, he is the namesake of the former autism spectrum disorder Asperger syndrome. He wrote more than 300 publications on psychological disorders that posthumously acquired international renown in the 1980s. His diagnosis of autism, which he termed "autistic psychopathy", garnered controversy. Further controversy arose in the late 2010s over allegations that Asperger referred children to the Am Spiegelgrund clinic, Am Spiegelgrund children's clinic in Vienna during the Nazi Germany, Nazi period. The clinic was responsible for murdering hundreds of disabled children deemed to be "Life unworthy of life, unworthy of life" as part of the Nazi Germany, Third Reich's Child euthanasia in Nazi Germany, child euthanasia programs, although the extent of Asperger's knowledge of this fact and his intentions in referring p ...

Leo Kanner
Leo Kanner (; born Chaskel Leib Kanner; June 13, 1894 – April 3, 1981) was an Austrian-American psychiatrist, physician, and social activist best known for his work related to infantile autism. Before working at the Henry Phipps Psychiatric Clinic at the Johns Hopkins Hospital, Kanner practiced as a physician in Germany and South Dakota. In 1943, Kanner published his landmark paper ''Autistic Disturbances of Affective Contact'', describing 11 children who displayed "a powerful desire for aloneness" and "an obsessive insistence on persistent sameness." He named their condition "early infantile autism". Kanner was in charge of developing the first child psychiatry clinic in the United States and later served as the ''Chief of Child Psychiatry'' at the Johns Hopkins Hospital. He is one of the co-founders of The Children's Guild, a nonprofit organization serving children, families and child-serving organizations throughout Maryland and Washington, D.C., and dedicated to "Transform ...

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

Autism Spectrum Disorder
Autism, also known as autism spectrum disorder (ASD), is a neurodevelopmental disorder characterized by differences or difficulties in social communication and interaction, a preference for predictability and routine, sensory processing differences, Special interest (autism), focused interests, and repetitive behaviors, which may include stimming. Formal Diagnosis of autism, diagnosis requires significant challenges in multiple domains of life, with characteristics that are atypical or more pronounced than expected for one's age and sociocultural context.(World Health Organization: International Classification of Diseases version 11 (ICD-11)): https://icd.who.int/browse/2024-01/mms/en#437815624 Motor coordination difficulties are common but not required for diagnosis.

Pervasive Developmental Disorder Not Otherwise Specified
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). According to the earlier DSM-IV, PDD-NOS referred to "mild or severe pervasive deficits 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 was one of four disorders 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. The ICD-10 equivalents also became part of its definition of autism spectrum disorder, as of the ICD-11. PDD-NOS included atypical autism, a diagnosis defined in the ICD-10 for the case that the criteria for ''autistic disorde ...
