Tic
A tic is a sudden, repetitive, nonrhythmic motor movement or vocalization involving discrete muscle groups.American Psychiatric Association (2000)DSM-IV-TR: Tourette's Disorder.''Diagnostic and Statistical Manual of Mental Disorders'', 4th ed., text revision (DSM-IV-TR), . Available at BehaveNet.com Retrieved on August 10, 2009. Tics can be invisible to the observer, such as abdominal tensing or toe crunching. Common motor and phonic tics are, respectively, eye blinking and throat clearing. Tics must be distinguished from movements of disorders such as chorea, dystonia and myoclonus; the compulsions of obsessive–compulsive disorder (OCD) and seizure activity; and movements exhibited in stereotypic movement disorder or among autistic people (also known as stimming). Classification Tics are classified as either motor or phonic, and simple or complex. Motor or phonic Motor tics are movement-based tics affecting discrete muscle groups. Phonic tics are involuntary sounds prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourette Syndrome
Tourette syndrome or Tourette's syndrome (abbreviated as TS or Tourette's) is a common neurodevelopmental disorder that begins in childhood or adolescence. It is characterized by multiple movement (motor) tics and at least one vocal (phonic) tic. Common tics are blinking, coughing, throat clearing, sniffing, and facial movements. These are typically preceded by an unwanted urge or sensation in the affected muscles known as a premonitory urge, can sometimes be suppressed temporarily, and characteristically change in location, strength, and frequency. Tourette's is at the more severe end of a spectrum of tic disorders. The tics often go unnoticed by casual observers. Tourette's was once regarded as a rare and bizarre syndrome and has popularly been associated with coprolalia (the utterance of obscene words or socially inappropriate and derogatory remarks). It is no longer considered rare; about 1% of school-age children and adolescents are estimated to have Tourette's, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Management Of Tourette Syndrome
Tourette syndrome (abbreviated as Tourette's or TS) is an inherited neurodevelopmental disorder that begins in childhood or adolescence, characterized by the presence of motor and phonic tics. The management of Tourette syndrome has the goal of managing symptoms to achieve optimum functioning, rather than eliminating symptoms; not all persons with Tourette's require treatment, and there is no cure or universally effective medication. Explanation and reassurance alone are often sufficient treatment; education is an important part of any treatment plan. Tourette syndrome patients may exhibit symptoms of other comorbid conditions along with their motor and phonic tics. Associated conditions include attention-deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), learning disabilities and sleep disorders. Patients who have ADHD along with Tourette's may also have problems with disruptive behaviors, overall functioning, and cognitive function. Co-occurring OCD can a ...

Obsessive–compulsive Disorder
Obsessive–compulsive disorder (OCD) is a mental and behavioral disorder in which an individual has intrusive thoughts and/or feels the need to perform certain routines repeatedly to the extent where it induces distress or impairs general function. As indicated by the disorder's name, the primary symptoms of OCD are obsessions and compulsions. Obsessions are persistent unwanted thoughts, mental images, or urges that generate feelings of anxiety, disgust, or discomfort. Common obsessions include fear of contamination, obsession with symmetry, and intrusive thoughts about religion, sex, and harm. Compulsions are repeated actions or routines that occur in response to obsessions. Common compulsions include excessive hand washing, cleaning, counting, ordering, hoarding, neutralizing, seeking assurance, and checking things. Washing is in response to the fear of contamination. Ordering is the preference for tasks to be completed a specific way (e.g., organizing clothes a specific w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coprolalia
Coprolalia () is involuntary swearing or the involuntary utterance of obscene words or socially inappropriate and derogatory remarks. Coprolalia comes from the Greek (''kópros''), meaning "dung, feces", and (''laliā́'') "speech", from (''laleîn'') "to talk". Coprolalia is an occasional characteristic of tic disorders, in particular Tourette syndrome, although it is not required for a diagnosis of Tourette's and only about 10% of Tourette's patients exhibit coprolalia. It is not unique to tic disorders; it is also a rare symptom of other neurological disorders. Coprolalia is one type of coprophenomenon. Other coprophenomena include the related symptoms of copropraxia, involuntary actions such as performing obscene or forbidden gestures, and coprographia, making obscene writings or drawings. Characteristics Coprolalia encompasses words and phrases that are culturally taboo or generally unsuitable for acceptable social use, when used out of context. The term is not used to de ...

Movement Disorder
Movement disorder refers to any clinical syndrome with either an excess of movement or a paucity of voluntary and involuntary movements, unrelated to weakness or spasticity. Movement disorders are synonymous with basal ganglia or extrapyramidal diseases. Movement disorders are conventionally divided into two major categories- ''hyperkinetic'' and ''hypokinetic''. Hyperkinetic movement disorders refer to dyskinesia, or excessive, often repetitive, involuntary movements that intrude upon the normal flow of motor activity. Hypokinetic movement disorders refer to akinesia (lack of movement), hypokinesia (reduced amplitude of movements), bradykinesia (slow movement), and rigidity. In primary movement disorders, the abnormal movement is the primary manifestation of the disorder. In secondary movement disorders, the abnormal movement is a manifestation of another systemic or neurological disorder.

Chorea (disease)
Chorea (or choreia, occasionally) is an abnormal involuntary movement disorder, one of a group of neurological disorders called dyskinesias. The term ''chorea'' is derived from the grc, χορεία ("dance"; see choreia), as the quick movements of the feet or hands are comparable to dancing. The term hemichorea refers to chorea of one side of the body, such as chorea of one arm but not both (analogous to hemiballismus). Presentation Chorea is characterized by brief, semi-directed, irregular movements that are not repetitive or rhythmic, but appear to flow from one muscle to the next. These 'dance-like' movements of chorea often occur with athetosis, which adds twisting and writhing movements. Walking may become difficult, and include odd postures and leg movements. Unlike ataxia, which affects the quality of voluntary movements, or Parkinsonism, which is a hindrance of voluntary movements, the movements of chorea and ballism occur on their own, without conscious effort. Thus, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Klazomania
Klazomania (from the Greek κλάζω ("klazo")—to scream) refers to compulsive shouting; it has features resembling the complex tics such as echolalia, palilalia and coprolalia seen in tic disorders, but has been seen in people with encephalitis lethargica, alcohol use disorder, and carbon monoxide poisoning. It was first reported by L. Benedek in 1925 in a patient with postencephalitic parkinsonism. Little is known about the condition, and few cases have been reported. Classification Klazomania shares some features with vocal tics seen in tic disorders including Tourette syndrome (TS). Klazomania was described in a 2006 journal review as a cause of tics differentiated from TS (tourettism), attributed to infectious processes (encephalitis) rather than TS. A 1996 case report on one patient by Bates ''et al'' suggested klazomania was a vocal tic. Signs and symptoms Klazomania is similar to other complex tics including echolalia, palilalia and coprolalia. It is defined as com ...

Stereotypic Movement Disorder
Stereotypic movement disorder (SMD) is a motor disorder with onset in childhood involving restrictive and/or repetitive, nonfunctional motor behavior (e.g., hand waving or head banging), that markedly interferes with normal activities or results in bodily injury. To be classified as SMD, the behavior in question must not be due to the direct effects of a substance, autism, or another medical condition. The cause of this disorder is not known. Signs and symptoms Common repetitive movements of SMD include head banging, arm waving, hand shaking, rocking and rhythmic movements, self-biting, self-hitting, and skin-picking; other stereotypies are thumb-sucking, dermatophagia, nail biting, trichotillomania, bruxism and abnormal running or skipping. Cause The cause of stereotypic movement disorder is unknown. Diagnosis Stereotyped movements are common in infants and young children; if the child is not distressed by movements and daily activities are not impaired, diagnosis is not warr ...

Premonitory Urge
A premonitory urge is a sensory phenomenon associated with Tourette syndrome and other tic disorders. Premonitory urges are "uncomfortable feelings or sensations preceding tics that usually are relieved by particularmovement". "Individuals with tics may have either a generalized or a localized sensation of tension that is relieved by movement, hat isthe tic." Sensory phenomena in tic disorders include bodily sensations, mental urges, and a sense of inner tension, feelings of incompleteness, and a need for things to be "just right". Bodily sensations include focal or generalized body sensations (usually tactile, muscular-skeletal/visceral, or both); mental sensations include urge only, energy release (mental energy that builds up and needs to be discharged), incompleteness, and just-right perceptions. Published descriptions of the tics of Tourette's identify sensory phenomena as the core symptom of Tourette syndrome, even though they are not included in the diagnostic criteria. ...

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 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 ...

An Anthropologist On Mars
''An Anthropologist on Mars: Seven Paradoxical Tales'' is a 1995 book by neurologist Oliver Sacks consisting of seven medical case histories of individuals with neurological conditions such as autism and Tourette syndrome. ''An Anthropologist on Mars'' follows up on many of the themes Sacks explored in his 1985 book, '' The Man Who Mistook His Wife for a Hat'', but here the essays are significantly longer and Sacks has more of an opportunity to discuss each subject with more depth and to explore historical case studies of patients with similar symptoms. In addition, Sacks studies his patients outside the hospital, often traveling considerable distances to interact with his subjects in their own environments. Sacks concludes that "defects, disorders, nddiseases... can play a paradoxical role, by bringing out latent powers, developments, evolutions, forms of life that might never be seen, or even be imaginable, in their absence" (p. ''xvi''). Essays *"The Case of the Colorblind Pai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudonym
A pseudonym (; ) or alias () is a fictitious name that a person or group assumes for a particular purpose, which differs from their original or true name (orthonym). This also differs from a new name that entirely or legally replaces an individual's own. Many pseudonym holders use pseudonyms because they wish to remain anonymous, but anonymity is difficult to achieve and often fraught with legal issues. Scope Pseudonyms include stage names, user names, ring names, pen names, aliases, superhero or villain identities and code names, gamer identifications, and regnal names of emperors, popes, and other monarchs. In some cases, it may also include nicknames. Historically, they have sometimes taken the form of anagrams, Graecisms, and Latinisations. Pseudonyms should not be confused with new names that replace old ones and become the individual's full-time name. Pseudonyms are "part-time" names, used only in certain contexts – to provide a more clear-cut separation between o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
