Tourettes Syndrome
The document discusses tic disorders, including transient tic disorder and Tourette syndrome, outlining their characteristics, prevalence, and diagnostic criteria. It emphasizes the relationship between tics and ADHD, noting that many youths have tics that usually do not require medical intervention and that ADHD medications can often be used safely without increasing tics. Treatment options for tic disorders are provided, including non-pharmacological approaches and the appropriate use of medication for managing symptoms.

Tourette Syndrome disorder named after Georges Gilles de la Tourette • Tourette syndrome is a common neuropsychiatric disorder characterized by the presence of fluctuating motor and phonic tics. • The typical age of onset is 5 7 years but age of first diagnosis is often > 10 years The typical age of onset is 5‐7 years but age of first diagnosis is often > 10 years • Boys are more commonly affected than girls • The majority of children improve by their late teens or early adulthood • Affected individuals are at increased risk for comorbid conditions, such as: obsessive‐compulsive disorder, attention deficit hyperactivity disorder, school problems (learning disability), depression, and anxiety. bl (l i di bilit ) d i d i t • The prevalence of Tourette is estimated to be between one and ten per 1000 children and adolescents • Differential diagnosis included many different movement disorders

- 9. Treatment of Tics • Transient tic disorder: education, reassurance; monitoring – NO MEDICATIONS • Medications for Tourette or chronic tics include: alpha adrenergic agonists anti agonists, anti‐ dopaminergics (eg. fluphenazine, haloperidol, pimozide and risperidone). Severe or treatment non‐responsive Tourette may be helped with deep brain stimulation or TMS. • Habit reversal therapy is a validated non‐pharmacological option: especially in mild cases: see ‐ http://onlinelibrary.wiley.com/doi/10.1002/9780470713518.app4/pdf • Atomoxetine may be useful for youth with ADHD and tics, although there are case reports of children d l i tics after i i i i treatment with A f hild developing i f initiating i h Atomoxetine. i • Presence of tics is not a contraindication for the use of ADHD medications • Specialty treatment for Tourette is suggested: a stepped approach is often used
- 10. The relationship between tics and ADHD p • The use of psychostimulant medication to treat ADHD can be associated with py the onset of tics – causal linkage unclear • No significant increase in tics when psychostimulants are used in patients with tics compared with controls • Youth with Tourette Syndrome have higher prevalence of ADHD, high variability in reports: 35% to 90% variability in reports: 35% to 90% • ADHD in youth with Tourette Syndrome may make impact of both disorders more severe • Psychostimulants are equally effective in improving ADHD symptoms whether the disorder is associated with tics or not
- 11. Conclusions Practical Conclusions Practical • Many young people have tics – they most often do not need medical intervention: education and watchful waiting if not Tourette Syndrome • Youth with ADHD may have more tics than youth without ADHD. Tics are not a contraindication to the use of ADHD medications (psychostimulants or atomoxetine) • Referral if: 1) diagnostic uncertainty (is it chronic tic disorder or Tourette Syndrome); 2) tics become significantly worse when ADHD medications are prescribed but medications are very helpful in significantl orse hen ADHD medications are prescribed b t medications are er helpf l in control of ADHD symptoms; 3) tics appear whenever any ADHD medication is prescribed; 4) patient has Tourette Syndrome with comorbidities. y A practical clinical tool to monitor motor and vocal tics in children: Yale Global Tic Severity Scale (YGTSS) http://dcf.psychiatry.ufl.edu/files/2011/06/TIC-YGTSS-Clinician.pdf
