Overview
• Tics & associated problems
• Assessment
• Tic management (non-Rx)
– Conventional
– Experimental
Take Home Points:
• TS is not rare
• Tics are usually mild, not catastrophic
• In most people with TS, tics are one of
many related complications
• Address main problems, often not tics
Who cares about Tourette syndrome?
• TS is:
– common
– under-diagnosed
– misunderstood
– ripe with opportunity for
management (and mismanagement)
& research
Tic Disorders: Characteristics
• Tic Definition
– motor or phonic
– involuntary (unvoluntary?)
– sudden and rapid
– recurrent
– non-rhythmic and stereotyped

Tourette’s Disorder
TM
• DSM-IV-TR Criteria
– Multiple motor + 1 or more vocal
– Many times/day & at least 1 year
– Onset before 18 years
– Not due to substance or medical
condition
Epidemiology
• “Official” prevalence
– 1 in 1,000 boys
– 1 in 5,000 girls
• Actual prevalence
– 1 in 100 boys (or even higher)
Etiology
• Neuro-anatomy and function
• Neurotransmitters
• Genetics

enough that we could
understand it, we’d be so

PANDAS

Pediatric

Genetics
• TS is genetic in origin
• TS is inherited
– family, twin and adoption studies
• Non-genetic factors also present
– Gestational exposure?
– Perinatal?
– Hormonal?
Genetics
barriers to identifying genes
• Diagnosis based on behaviors
• Defining the TS phenotypic spectrum
– “endophenotypes”

Diagnostic Pitfalls 101
• Subject or clinician unaware of tics
• Waxing and waning nature of tics
• Tics are suppressible
Diagnostic Pitfalls 102
•
•
•
•
T.S. is not rare
T.S. is usually not catastrophic
Few have coprolalia
You may not see the tics

Clinical Course
•
•
•
•
•
•
•
Hyperactivity often precedes tics
Head and neck tic onset age 6 to 7
Vocal tics age 8 to 9
Obsessive-Compulsive symptoms 11-12
Peak tic severity age 10 to 11
Often see decrease in tics
Tics lifelong in 50% to 90%
Quality of Life?
Quality of Life?
“Tourette differs from other
neuropsychiatric disorders in one
simple way: It is largely the disease of
the onlooker. When I tic, I am usually
not the problem. You are.”
Peter Hollenbeck, Ph.D.
(a neuroscientist with TS)
-Cerebrum (2003)
Management
• General Guidelines
– Education
– Monitoring (tics and non-tics)
– Containment
Identification
• Clinical aspects of tics
• Comorbid conditions
• Emotion and behavior
Identification – comorbid conditions
KEY POINT!
Always assess for non-tic comorbidity
* 90% occurrence if tics mild
* 100% occurrence if tics severe
*in clinically-referred samples
Identification – comorbid conditions

Management
• Is additional treatment needed:
– for tics?
– for co-morbid conditions?
Management
• Perspectives:
– The child
– The parent
– The school
– You

Pharmacotherapy
KEY POINTS!
•Do not assume medication is necessary
•Address comorbid condition(s)
•Complete tic remission is rare
•Stimulants are generally safe
Pharmacotherapy
International Psychopharmacology Algorithm
Project
Category A
Good supportive evidence (short-term safety and efficacy)
Category B
Fair supportive evidence (short-term safety and efficacy)
Category C
Minimal supportive evidence (short-term safety and efficacy)
