DISCLOSURES
I have the following financial relationships with the manufacturers of commercial products and/or providers of commercial services:Ecopipam Pharmaceuticals, EryDel Pharmaceuticals, and Neurocrine Pharmaceuticals -
Research Grant
(Please note: Clinical trial site investigator);
Elsevier – Royalties for books
I have been site investigator for a Phase 2 study of a new medication for Tourette Syndrome, which I will not discuss.
I do not intend to discuss an unapproved/investigative use of a commercial products (drugs, devices) related to these relationships.

often have co-occurring ADHD, OCD, and other developmental or psychiatric symptoms
3. Recognize common areas of impairment in TS in home, school, and social domains
4. Apply individualized treatment strategies for impairing symptoms in children with tics/ Tourette Syndrome

1. Educate parents and kids about impairment and outcomes in tic disorders.
2. When tics are impairing, offer opportunities for behavioral/non-medical interventions.
3. Consider tics but also comorbidities in treatment decisions.
As a result of attending this lecture at the 2017 Practical Pediatrics CME course, I encourage you to make the following change in your practice

Tics
• Patterned, discrete, countable (usually)
• Repetitive but Non-rhythmic
• Increase with stress• Decrease with focused
activity
• Semi-voluntary: “I have to do it”
• Semi-suppressible• Sensory Urge• Onset usually after age 3• Upper body > lower body

Key Distinguishing Features of tics versus stereotypies
Feature TICS STEREOTYPIES
Age of onset Usually after age 3 years Usually before age 3 years
Evolution over time
Over weeks to months, waxing, waning, migrating location. Peak age 9-14 years.
Remain relatively unchanged from onset, last for years; may persist into adulthood but frequency diminishes in adolescence in non-autistic kids.
Exacerbating factors or situations
Stress, excitement, relaxation after a busy period
Occur in certain emotional states: happiness –excitement, boredom, anxiety, sensory overloaded/socially overwhelmed

Clinical Criteria for diagnosis of Tourette Syndrome
• 2 or more motor tics, 1 or more phonic tics• Duration > 1 year• Anatomic location, number, frequency,
complexity, severity changes over time• Onset before age 21• Not iatrogenic or a symptom of another
Diagnosis• Prevalence is 3-6 per 1000

WHAT TO DO WHEN TICS BEGIN ON STIMULANTS?
•If the tics are very mild and the stimulants are clearly beneficial, stay on the stimulants and wait it out
•Try reducing the dose (I rarely exceed 1 mg/kg/day)
•Stop stimulant, try an alternative medication for a while (clonidine, guanfacine)
![Page 34: TICS AND TOURETTE SYNDROME - The American … · 1. Distinguish between tics and complex motor stereotypies 2. Recognize that children with tics and Tourette Syndrome often have co-occurring](https://reader031.fdocuments.in/reader031/viewer/2022011805/5bb833b409d3f2cd2f8bd6c1/html5/thumbnails/34.jpg)
FIRST-LINE TREATMENT OF TICS – CLASS B EVIDENCE
• Alpha 2 adrenergic agonists: clonidine (Catapres), guanfacine (Tenex, Intuniv) -- fight or flight
• Probably harmless long-term
• 20-50% effective for tics
• May not work for 2-6 weeks
• Also help with ADHD and aggression
• Side effects mainly sedation (25-50% with clonidine)

INTERMEDIATE OPTIONS – SECOND LINE CLASS B TO C
•Topiramate
•Dopamine agonists
•Baclofen, a muscle relaxant
•Botox
•Anti-anxiety medications
![Page 36: TICS AND TOURETTE SYNDROME - The American … · 1. Distinguish between tics and complex motor stereotypies 2.

THIRD LINE TREATMENT FOR TICS – CLASS A
• Neuroleptics / dopamine antagonists: haloperidol (Haldol), pimozide (Orap), fluphenazine (Prolixin), risperidone (Risperdal), aripiprazole (Abilify)• Highest efficacy
• Multiple short-term side effects
• weight gain, sedation, anxiety, depression...
• Need to monitor for neuroleptic-induced movement disorders
![Page 37: TICS AND TOURETTE SYNDROME - The American … · 1. Distinguish between tics and complex motor stereotypies 2.

SUMMARY OF TREATMENT INDICATIONS FOR TICS
• Base treatment decisions on impairment
• Rank tic vs. non-tic impairment and get perspective of child and parent
• Most individuals with tics do not need medication for tics
• Consider medications for persistent tics if they cause:• Functional impairment (uncommon)• Social impairment or classroom/workplace disruption• Pain

LONGTERM OUTCOMES FOR TICS?
• Brain seems to develop compensatory functions – tics most often diminish in adulthood
• Create resilience!
![Page 39: TICS AND TOURETTE SYNDROME - The American … · 1. Distinguish between tics and complex motor stereotypies 2. Recognize that children with tics and Tourette Syndrome often have co-occurring](https://reader031.fdocuments.in/reader031/viewer/2022011805/5bb833b409d3f2cd2f8bd6c1/html5/thumbnails/39.jpg)
1. Educate parents and kids about impairment and outcomes in tic disorders.
2. When tics are impairing, offer opportunities for behavioral/non-medical interventions. CBIT is a proven therapy.
3. Rank and target – comorbid symptoms may cause more impairment. It is OK to treat ADHD pharmacologically with stimulants despite presence of tics.
As a result of attending this lecture at the 2017 Practical Pediatrics CME course, I encourage you to make the following change in your practice
