  • Tourette's Syndrome
    Tourette’s Syndrome CHRISTOPHER KENNEY, MD; SHENG-HAN KUO, MD; and JOOHI JIMENEZ-SHAHED, MD Baylor College of Medicine, Houston, Texas Tourette’s syndrome is a movement disorder most commonly seen in school-age children. The incidence peaks around preadolescence with one half of cases resolving in early adult- hood. Tourette’s syndrome is the most common cause of tics, which are involuntary or semi- voluntary, sudden, brief, intermittent, repetitive movements (motor tics) or sounds (phonic tics). It is often associated with psychiatric comorbidities, mainly attention-deficit/hyperac- tivity disorder and obsessive-compulsive disorder. Given its diverse presentation, Tourette’s syndrome can mimic many hyperkinetic disorders, making the diagnosis challenging at times. The etiology of this syndrome is thought to be related to basal ganglia dysfunction. Treatment can be behavioral, pharmacologic, or surgical, and is dictated by the most incapacitating symp- toms. Alpha2-adrenergic agonists are the first line of pharmacologic therapy, but dopamine- receptor–blocking drugs are required for multiple, complex tics. Dopamine-receptor–blocking drugs are associated with potential side effects including sedation, weight gain, acute dystonic reactions, and tardive dyskinesia. Appropriate diagnosis and treatment can substantially improve quality of life and psychosocial functioning in affected children. (Am Fam Physician. 2008;77(5):651-658, 659-660.

  • 1 Tourette Syndrome Is a Neurodevelopmental Disorder That
    Tourette Syndrome is a neurodevelopmental disorder that is complex and often misunderstood. This presentation will provide you with an introduction to Tourette Syndrome (TS) and to conditions that frequently occur with TS, such as Obsessive- Compulsive Disorder, Attention Deficit Hyperactivity Disorder, Executive Dysfunction, and other learning disabilities. This presentation is intended for school-based professionals who may be working with students who have TS. The Association recommends that school psychologists, nurses, special education directors, and other training staff use this as a tool to educate their faculty and staff. 1 This slide is included as a reminder of how critically important teachers’ responses are to all children. We all have days that are more difficult to get through than others, but it is so important to always recognize the power teachers hold regarding a student’s academic education, as well as his or her social abilities and self-worth. The teacher is a role model for the entire class. His or her actions will often have a bigger impact than words. Demonstrating a positive attitude verbally as well as non-verbally is critically important. We are hopeful that providing information regarding this complex and highly misunderstood disorder will assist you in recognizing symptoms and providing positive supports for children with TS. 2 The office of the Tourette Association of America is located in Bayside, New York. The Association was founded in 1972 and it is the only national, voluntary, non-profit membership organization dedicated to identifying the cause, finding the cure and controlling the effects of TS. 3 Tourette Syndrome is a hereditary, neurodevelopmental disorder that is often first recognized in childhood, usually between the ages of 6 and 10.

Aamir Jalal Al Mosawi, Senior Advisor Doctor, Baghdad Medical City , Head, Iraq Headquarter of Copernicus Scientists International Panel, Baghdad, Iraq. Submitted: 12 Oct 2020; Accepted: 15 Nov 2020; Published: 26 Nov 2020 Abstract Background: Gilles de la Tourette syndrome is a neuro-psychiatric condition associated with rather bizarre manifestations and generally affects children with normal intelligence. The condition has the potential to make an intelligent child a victim of the disorder, and unfavorably affects his/her school performance and lead to social rejection and isolation. Awareness by the community, educators, and also medical practitioners is useful and help in avoiding the loss of such children who have the potential to be a talented person. The aim of this paper is to present a case and to provide a brief account on the early documentation of syndrome in the literature. Patients and Methods: The case of a ten-year old boy with Gilles de la Tourette syndrome is described and the relevant literatures were reviewed to outline the early documentation of the disorder in the literature. Results: A.Y was first seen at the pediatric psychiatric clinic of the Children Teaching Hospital of Baghdad Medical City at the age of ten years because they were saying at school that the boy is crazy because of his abnormal behaviors.

The aim of the paper was to assess the incidence and clinical associations of CTPh in GTS, and to establish if CTPh belong to the tic spectrum. We performed a prospective, one-registration study on a cohort of 227 consecutive patients with GTS. CTPh were diagnosed during the interview and defined as brief, sudden, involuntary thoughts that had corresponding complex vocal tics. CTPh occurred at some point in the lives of 34 (15.0%) patients. The median age at onset of CTPh was 14.5 years (IQR: 10.5–17.5). CTPh were found more frequently in adults, with the most frequent onset in adolescence (44.1%). Four mental phenomena resembling tics were recognized: echolalia (n = 17), coprolalia (n = 16), palilalia (n = 13) and repeating of words in the mind (n = 7).

  • Neurobehavioural Correlates of Abnormal Repetitive Behaviour
    Behavioural Neurology, 1991,4, 113-119 Neurobehavioural Correlates of Abnormal Repetitive Behaviour R. A. FORD Springfield Hospital Glenbumie Road, London SW17, UK Correspondence to: Warlingham Park Hospital, Warlingham, Surrey CR3 9YR, UK Conditions in which echolalia and echopraxia occur are reviewed, followed by an attempt to elicit possible mechanisms of these phenomena. A brief description of stereotypical and perseverative behaviour and obsessional phenomena is given. It is suggested that abnormal repetitive behaviour may occur partly as a result of central dopaminergic dysfunction. Introduction Repetition of the motor activities or language of another person is usually under voluntary control; if it becomes an involuntary process it may be indicative of an underlying disease process. Echophenomena is a term which encompasses echolalia and echopraxia. Echolalia is the repetition of another individual's speech, and does not usually serve a communicative purpose. Echopraxia is the repetition of another individual's motor activities, and is usually non-goal-directed. Echolalia is found in conditions in which there is an abnormality or immaturity of communicative processes, such as in acquired deafness, during normal childhood speech development, transcor­ tical aphasias and childhood autism. Echolalia and echopraxia are fre­ quently found together in conditions such as catatonia, Gilles de la Tourette syndrome and the hyperekplexias. Other phenomena characterized by an excessive tendency to repetition are mannerisms, stereotyped behaviour and perseveration. Stereotyped behaviour has been defined as repetitive, non­ goal-directed actions which are carried out in a uniform way. If the particular behaviour is thought to be goal-directed, it is classified as a mannerism (Fish, 1974), although the distinction between the two is an artificial one.

  • Secondary Tics and Tourettism Tiques Secundários E Touretismo
    11 ORIGINAL ARTICLE Secondary tics and tourettism Tiques secundários e touretismo Nicte I Mejia,1 Joseph Jankovic1 Original version accepted in English Abstract Motor and phonic tics are most frequently due to Tourette syndrome, but there are many other causes of tics. We analyzed data on 155 patients with tics and co-existent disorders (101M/54F; mean age 40.5 ± 20.2 years). Fourteen (9.0%) patients had tics associated with an insult to the basal ganglia, such as head trauma (N = 4, 2.5%), stroke (N = 2, 1.2%), encephalitis (N = 3, 1.9%) and other causes. In addition, certain drugs, toxins, and post-infectious causes were associated with tics. Rarely, peripheral injury can cause movement disorders, including tics (N = 1, 0.6%). Pervasive developmental disorders, including Asperger’s syndrome (N = 13, 8.3%), mental retardation (N = 4, 2.5%), autism (N = 3, 1.9%), and Savant’s syndrome (N = 1, 0.6%), also may be associated with tics, as noted in 21 of the 155 patients (13.5%). Genetic and chromosomal disorders, such as Down’s syndrome 5 (3.2%), neuroacanthocytosis (N = 2, 1.2%), and Huntington’s disease (N = 1, 0.6%), were associated with tics in 16 patients (10.3%). We have also examined the co-existence of tics and other movement disorders such as dystonia (N = 31, 20.0%) and essential tremor (N = 17, 10.9%). Sixteen (10.3%) patients presented psychogenic tics, and one (0.6%) psychogenic tics and dystonia; conversely, Tourette syndrome preceded the onset of psychogenic dystonia (N = 1, 0.6%), and psychogenic tremor (N = 1, 0.6%) in two patients.
