Knowledge, education and understanding are uppermost in management plans for tic disorders, [6] and psychoeducation is the first step. [14] [15] A child's parents are typically the first to notice their tics; [16] they may feel worried, imagine that they are somehow responsible, or feel burdened by misinformation about Tourette's. [14]
Tic disorders are defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM) based on type (motor or phonic) and duration of tics (sudden, rapid, nonrhythmic movements). [1] Tic disorders are defined similarly by the World Health Organization ( ICD-10 codes).
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.
A. Either one or multiple motor and/or vocal tics, for example, motor or vocal noises that are rapid, repeated, sudden, and nonrhythmic. B. The tics happen multiple times over the course of the day, almost every day for at least 4 weeks, but do not occur continually for any longer than 1 year. C. Symptoms are present before the age of 18. D.
Specific treatment options for reliving motor and phonic tics (coprolalia) in Gilles de la Tourette syndrome include but are not limited to Botulinum toxin injections, antipsychotics or behavioral therapy depending on the individual's severity of symptoms.
Controlled trials have demonstrated that HRT is an acceptable, tolerable, effective and durable treatment for tics; [1] HRT reduces the severity of vocal tics, and results in enduring improvement of tics when compared with supportive therapy. [7] HRT has been shown to be more effective than supportive therapy and, in some studies, medication. [8]
Motor tics are movement-based tics affecting discrete muscle groups. [4]Phonic tics are involuntary sounds produced by moving air through the nose, mouth, or throat. They may be alternately referred to as verbal tics or vocal tics, but most diagnosticians prefer the term phonic tics to reflect the notion that the vocal cords are not involved in all tics that produce sound.
Palilalia is defined as the repetition of the speaker's words or phrases, often for a varying number of repeats. Repeated units are generally whole sections of words and are larger than a syllable, with words being repeated the most often, followed by phrases, and then syllables or sounds.
