The aims of this descriptive study were to examine the prevalence and associations of coprophenomena (involuntary expression of socially unacceptable words or gestures) in individuals with Tourette syndrome. Participant data were obtained from the Tourette Syndrome International Database Consortium. A specialized data collection form was completed for each of a subset of 597 consecutive new patients with Tourette syndrome from 15 sites in seven countries. Coprolalia occurred at some point in the lifetime of 19.3% of males and 14.6% of females, and copropraxia in 5.9% of males and 4.9% of females. Coprolalia was three times as frequent as copropraxia, with a mean onset of each at about 11 years, 5 years after the onset of tics. In 11% of those with coprolalia and 12% of those with copropraxia these coprophenomena were one of the initial symptoms of Tourette syndrome. The onsets of tics, coprophenomena, smelling of non-food objects, and spitting were strongly intercorrelated. Early onset of coprophenomena was not associated with its longer persistence. The most robust associations of coprophenomena were with the number of non-tic repetitive behaviors, spitting, and inappropriate sexual behavior. Although coprophenomena are a frequently feared possibility in the course of Tourette syndrome, their emergence occurs in only about one in five referred patients. Because the course and actual impact of coprophenomena are variable, additional prospective research is needed to provide better counseling and prognostic information.

    • "Coprolalia, the involuntary expression of socially inappropriate utterances, is seen in just 19% of males and 14% of females with TS (Freeman et al., 2009). Environmental and emotional factors such as anxiety can worsen tic frequency (Conelea and Woods, 2008); therefore, schools can potentially play an important role in reducing the negative impact of TS on educational and psychosocial adjustment by attending to these factors.

    ABSTRACT: Tourette syndrome is a neurological condition involving involuntary movements and sounds (tics) and is thought to affect as many as 1% of school-aged children. Some young people with Tourette syndrome experience educational difficulties and social difficulties. Current clinical guidelines suggest educators can play an important role in maximising learning potential and reducing the negative impact of this condition on students' social adjustment. Secondary school staff (N = 63) with responsibilities for special educational needs or disabilities completed a survey about support strategies for students with Tourette syndrome. Participants were first asked to suggest potentially helpful strategies and then rated how easily 17 recommended strategies could be implemented in school. The survey participants suggested a range of support strategies that were categorised as (1) promoting knowledge and understanding in school, (2) helping the student to cope with his/her tics, (3) supporting the student's learning and (4) providing social and emotional support. All the recommended support strategies were rated as being easy to implement (or already in place) by the majority of respondents (e.g., increasing staff awareness and regular communication with home). The strategies that were identified as being least easy to implement were those requiring extra staff input (support from teaching assistants and individual/small group working). Additional challenges to providing support were also identified by the participants (e.g., getting input from outside agencies).

    • "Vocalizations such as words or short phrases (e.g., " oh boy " , " you bet " ) can also occur. Although often believed to be prototypic of TS, coprolalia, or bouts of uncontrolled cursing, affects only an estimated 18.5% of patients (Freeman et al., 2009). Many individuals with TS experience premonitory urges associated with tics, with some difficulty in urge recognition among youth under 10 years of age (Woods et al., 2005). "

    ABSTRACT: Cluster analytic methods have examined the symptom presentation of chronic tic disorders (CTDs), with limited agreement across studies. The present study investigated patterns, clinical correlates, and treatment outcome of tic symptoms. 239 youth and adults with CTDs completed a battery of assessments at baseline to determine diagnoses, tic severity, and clinical characteristics. Participants were randomly assigned to receive either a comprehensive behavioral intervention for tics (CBIT) or psychoeducation and supportive therapy (PST). A cluster analysis was conducted on the baseline Yale Global Tic Severity Scale (YGTSS) symptom checklist to identify the constellations of tic symptoms. Four tic clusters were identified: Impulse Control and Complex Phonic Tics; Complex Motor Tics; Simple Head Motor/Vocal Tics; and Primarily Simple Motor Tics. Frequencies of tic symptoms showed few differences across youth and adults. Tic clusters had small associations with clinical characteristics and showed no associations to the presence of coexisting psychiatric conditions. Cluster membership scores did not predict treatment response to CBIT or tic severity reductions. Tic symptoms distinctly cluster with little difference across youth and adults, or coexisting conditions. This study, which is the first to examine tic clusters and response to treatment, suggested that tic symptom profiles respond equally well to CBIT. Clinical identifiers: NCT00218777; NCT00231985.

    • "The rates of coprolalia (10.6%) and copropraxia (6.4%) among women in our sample were comparable to previously reported data (14.6% and 4.9%, respectively [56]). Income breakdown for women in our sample was as follows: 12% reported earning greater than $75 000, 13% reported earning $50 000-75 000, 18% reported earning $30 000-49 000, 14% reported earning $20 000-29 000, 15% reported earning 10 000-19 000 and 28% reported earning less than $10 000.

    ABSTRACT: There are little data concerning clinical characteristics of women with Tourette disorder and chronic tic disorders in the extant literature and what is available mostly focuses on treatment-seeking individuals. The present research was conducted to provide a phenomenological characterization of tic disorders among 185 adult women with tic disorders. In addition to providing a descriptive overview of specific tic symptoms, tic severity, self-reported history of other psychiatric conditions, and impairment/lifestyle impact due to tics, this study compares 185 women and 275 men between 18 and 79 years old with tic disorders (who completed an identical battery of measures) based on demographic, social/economic status indicators, psychiatric variables (comorbidity, family psychiatric history, symptom presentation), adaptive functioning/quality of life, and impairment variables among a nonclinical adult sample. Finally, this research examines the relationship between tic severity and impairment indicators among women with tics. Sixty-eight percent of women in our sample reported severe motor tics and 40% reported severe phonic tics. Our exploratory data suggest that a sizeable number of adult women with persistent tics are suffering from psychiatric comorbidity and psychosocial consequences such as underachievement and social distress. Tic severity in women may be associated with lifestyle interference as well as with symptoms of depression and anxiety, and such symptoms may be more common among women with tics than in men with tics.
