Utilizando bibliografía que data del siglo XIX y complementándola con la literatura más actual sobre el tema, se pretende abarcar los principales aspectos de este síndrome, a fin de que obtener un conocimiento profundo sobre el mismo. Para ello se revisan desde los primeros casos expuestos por Gilles de la Tourette y Freud, hasta los tratamientos psicofarmacológicos actuales para los tics. Así mismo, se hace un énfasis en la neuropatogénesis del síndrome de Gilles de la Tourette y sus implicaciones en las funciones superiores de quien lo padece. Introducción En las últimas décadas, el estudio de las funciones cerebrales ha recibido mucha atención por parte de la comunidad científica, con la intención de desarrollar métodos de diagnóstico y tratamiento de afecciones del sistema nervioso. El síndrome de Gilles de la Tourette (ST) es uno de estos padecimientos, no obstante su baja incidencia, puede ser incapacitante para quien lo padece. Debido a su alta comorbilidad con otros trastornos como el trastorno obsesivo compulsivo y el trastorno por déficit de atención; el diagnóstico diferencial del ST representa un reto para el especialista por lo que éste requiere de un conocimiento profundo acerca del mismo. Este trabajo tiene como objetivos contribuir a una mejor comprensión de este síndrome para que sea más fácilmente reconocido en forma diferencial por quienes lo evalúan y para orientar al profesional de la salud sobre posibles formas de abordaje del mismo. Para lograr estos objetivos, se hace una revisión bibliográfica exhaustiva, iniciando desde los antecedentes históricos del estudio de este padecimiento, hasta los últimos tratamientos propuestos. 1. Antecedentes Históricos Areteo de Capadocia, un médico griego del siglo I D.C., describió varios casos de personas que emitían ladridos, maldiciones y blasfemias involuntarias, además de extraños movimientos (Sacks, 1997). ). Sin embargo, no sería sino hasta finales del siglo XIX que se describiría y aceptaría al ST como una entidad clínica separada de otros padecimientos. Gilles de la Tourette, compañero de Freud y alumno de Charcot, presentó en 1885 un artículo con una nueva tipología de diagnóstico, un síndrome denominado „Maladie des Tics de Gilles de la

The key feature is tics – involuntary and uncontrollable sounds and movements. It is a complex condition and covers an extraordinarily wide spectrum. People may have a very mild form of Tourette Syndrome (TS). They and those close to them may not even be aware that they have TS. At the other end of the scale, medical symptoms are extreme and the social, educational and economic effects are serious. These are the examples that generate media interest.

    Tourette Syndrome affects up to one in 2,500 people. It is a genetic disorder. Either parent can pass on a vulnerability to develop Tourette Syndrome. 70% of female carriers show symptoms but 99% of male carriers show symptoms. In 10-15% of Tourette Syndrome patients there is no genetic cause. Treatment is by drugs. Up to 80% benefit from haloperidol and other drugs are available. ADHD children who also have Tourette Syndrome should avoid stimulant medication.

  • Relaxation Therapy As a Treatment for Tics in Patients with Tourette Syndrome: a Systematic Literature Review
    Neurological Sciences https://doi.org/10.1007/s10072-019-04207-5 REVIEW ARTICLE Relaxation therapy as a treatment for tics in patients with Tourette syndrome: a systematic literature review Florence Tilling1 & Andrea E. Cavanna1,2,3 Received: 8 October 2019 /Accepted: 17 December 2019 # The Author(s) 2019 Abstract Background Tourette syndrome (TS) is a neurodevelopmental condition characterized by the presence of multiple motor and phonic tics, often associated with co-morbid behavioural problems. Tics can be modulated by environmental factors and are characteristically exacerbated by psychological stress, among other factors. This observation has led to the development of specific behavioural treatment strategies, including relaxation therapy. Objective This review aimed to assess the efficacy of relaxation therapy to control or reduce tic symptoms in patients with TS. Methods We conducted a systematic literature review of original studies on the major scientific databases, including Medline, EMBASE, and PsycInfo, according to the standards outlined in the Preferred Reporting Items for Systematic Reviews and Meta- Analyses (PRISMA) guidelines. Outcomes measures included both tic severity and tic frequency. Results Our literature search identified three controlled trials, with a total number of 40 participants (range: 6–18 participants). In all three studies, relaxation therapy decreased the severity and/or the frequency of tic symptoms. However, the only trial comparing relaxation therapy to two other behavioural techniques found relaxation therapy to be the least effective intervention, as it reduced the number of tics by 32% compared to 44% with self-monitoring and 55% with habit reversal. Discussion The results of this systematic literature review provide initial evidence for the use of relaxation therapy as a behav- ioural treatment intervention for tics in patients with TS.
