22
Tourette’s Disorder DSM-IV-TR TM Criteria –Multiple motor plus 1 or more vocal –Many times/day and at least 1 year –Onset before 18 years –Not due to substance or medical condition
23
Chronic Tic Disorder (M or V) DSM-IV-TR TM Criteria –Multiple (or single) motor or vocal –Many times/day and at least 1 year –Onset before 18 years –Not due to substance or medical condition
24
Transient Tic Disorder DSM-IV-TR TM Criteria –Multiple (&/or single) M. &/or V. –Many times/day (4 weeks – 1 year) –Onset before 18 years –Not due to substance or medical condition
25
Tourette’s Disorder DSM-V –Duration criterion for chronic tics Tics persist for > 1 yr since first tic onset Changes from DSM-IV-TR. Removed: –More than 9/12 months of any year –Tic-free period of no more than 3 months –Transient Tic Disorder –Provisional tic disorder
26
Tourette’s Disorder DSM-V –Duration criterion for chronic tics Tics persist for > 1 yr since first tic onset Changes from DSM-IV-TR. Removed: –More than 9/12 months of any year –Tic-free period of no more than 3 months –Transient Tic Disorder –Provisional tic disorder
27
PREMONITORY URGE
28
Tics: Characteristics Anatomic evolution of tics top →bottom midline→peripheral simple→complex
29
Anatomic evolution of tics
40
Epidemiology Prevalence – 1% males (or more) – Male > Female (3-to-10 times)
42
“If the brain were simple enough that we could understand it, we’d be so simple that we couldn’t” Paul Greengard, Ph.D. Nobel Prize in Physiology or Medicine 2000
43
Tics: Pathophysiology Cortical & Subcortical network – Sensory – Affective – Motor
44
Tic Disorders: Characteristics Premonitory urge Tics can usually be suppressed
45
Etiology URGE → TIC → RELIEF
46
Tics: Pathophysiology Dis-inhibition – “sensori-motor gating” – “filtering” Motor programs – “fixed action patterns” – “muscle memory”

49
PANDAS controversial Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections
50
PANDAS 5 identifying criteria developed for research by clinical observation 1.Dramatic emergence or exacerbation of OCD and/or tics 2.Pre-pubertal symptom onset 3.Other neurological signs 4.Association with GABHS 5.Episodic or sawtooth symptom course
51
Genetics TS is genetic in origin TS is inherited –family, twin and adoption studies Non-genetic factors also present –Gestational exposure? –Perinatal? –Hormonal?
52
Genetics Major genes are involved –autosomal dominant w/incomplete penetrance? –polygenic? –additive? Genomic regions suspected –Seeking susceptibility genes in the regions Epigenetic factors
53
Differential Diagnosis of repetitive behaviors NeurologicalPsychiatric Sydenham choreaCompulsions MyoclonusStereotypies TremorPerseverations DystoniaSelf-injurious behavior AthetosisAddictive behaviors SpasmsHabits DyskinesiasMannerisms
54
Differential Diagnosis of repetitive thoughts Psychiatric Obsessions Ruminations Delusions Perseverative thoughts Cravings Over-valued ideas Flash-backs
56
Identification Clinical aspects of tics Comorbid conditions Emotion and behavior
57
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
58
Assessment: co-morbid conditions ADHD Obsessions/Compulsions Learning interferences Behavioral disorders Developmental disorders Mood disorders Anxiety Social difficulties (including PDDs)

Clinical Course < 7ADHD 7Simple motor tic (head) 8Vocal tic 11OCS + peak tic severity > 11 tics ↓ (but lifelong in 50-90%)
66
Time course of symptom dev’t Autism, Abuse/Neglect ADHD, Anxiety Depression, ODD Bipolar, Conduct Personality Disorder, Conduct Disorder Adapted from presentation by John Walkup, MD
67
Clinical Assessment: complex presentations Tics plus: – separation (or other) anxiety – autism – disruptive behavior disorders – depression (or bipolar) – substance abuse – personality disorders
68
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)
69
Diagnostic Pitfalls 101 Subject or clinician unaware of tics Waxing and waning nature of tics Tics are suppressible
70
Diagnostic Pitfalls 102 T.S. is not rare T.S. is usually not catastrophic Few have coprolalia You may not see the tics
71
Management General Guidelines –Education –Monitoring –Containment
72
Management Containment - overcome assumptions –“He can’t control it” –“I can’t set limits on him” –“He has a tough life. I want it easier” – “He needs special accommodations” –“Medication is the answer” –“It’s all related to the Tourette” Adapted from a presentation by John Walkup, MD
73
Management Anger: An easily conditioned behavior –Effective in interactions –Associations: Mood & Anxiety Cognitive / Brain –Culture Adapted from a presentation by John Walkup, MD
74
Management General Guidelines - Education –Clarify neurological basis –Reassurance and support –Emphasize strengths –Whole child –Whole family
75
Management Outcome is associated with: Severity of co-occurring conditions & self-control + The courage to overcome adversity Adapted from presentation by John Walkup, MD
76
Management Is further treatment necessary: –For tics? –For comorbid conditions? Caution: There is often > 1 condition
77
Management Lumpers vs. Splitters – Tic suppression – Co-occurring conditions – Children: Raising kids w/ TS – Adults: Building on strengths Adapted from presentation by John Walkup, MD
78
Management Splitters – Make problem list – Rank & treat by impairment – Treat each problem/diagnosis – Consider consult – Goal: “Fix” other diagnoses Adapted from presentation by John Walkup, MD
79
Management Splitter – OCD: CBT & / or Rx – Behavior: Parent training – Tics: Education, Advocacy, Monitor, Consider Rx (esp. α2 agonist) Adapted from presentation by John Walkup, MD
80
Management Lumpers problem problem problem problem problem Adapted from presentation by John Walkup, MD Tourette
81
Management Perspectives: – The child – The parent – The school – You
82
Management parent perspective Most Important –Episodic rage –Attention deficit –Learning difficulties Least Important –Motor tics –Vocal tics
83
FOCUS ON TARGET SYMPTOMS
84
Types of Reinforcement Adapted from presentation by John Walkup, MD +- Internal Gratification Relieves distress External Attention & Support Avoidance
85
Management: tics Education & Accommodation Medications Experimental – Behavioral – Integrative – Surgical
86
Management - tics Non-pharmacological –Dynamic psychotherapy Supportive Cognitive-Behavioral Parenting education
87
Management – tics: environment Things that worsen tics –Excitement & stress –Fatigue –Attending to tics / Accepting of tics Things that improve tics –Calm, focused activities –Deep relaxation –Inhibiting environments Adults’ experience w/behavior strategies Adapted from presentation by John Walkup, MD
88
Management - tics Non-pharmacological –Behavioral approaches CBIT (Comprehensive Behavioral Intervention for Tics) –HRT (Habit Reversal Therapy) »Awareness Training »Competing Response »Relaxation »Social Support –FA (Functional Analysis) »Social situations that influence behaviors
89
Management - tics Non-pharmacological –Behavioral approaches CBIT –Behavioral Antecedent - Behavior - Consequence –Functional + & - reinforcing functions
90
Change in Advice Adapted from presentation by John Walkup, MD OLD (intuitive)NEW (counterintuitive) Ignore ticsBecome more aware Can’t be controlledLearn to manage Don’t punishReward successful mgt Behavior tx won’t workUse beh. strategies Don’t try to suppressBeh. tx. doesn’t ↑ tics Suppression ↑ ticsUrges will fade away Suppression ↑ urgesBeh. tx. doesn’t create new tics
91
Management - tics Teacher in-service on T.S. Classroom education on T.S. Teacher as role model Tic breaks/sanctuaries Testing accommodations Opportunities for movement Scribes Tic suppression (behavioral and/or medical)
92
Management: “co-morbid” conditions – Family dysfunction – OCD & other anxiety disorders – ADHD – Learning difficulties – Behavioral Disorders – Sleep disturbances – Other self-injurious behaviors
93
Management – bullying Stop Bullying Now - HRSA www.stopbullyingnow.hrsa.gov
96
Pharmacotherapy KEY POINTS! Do not assume medication is necessary Address comorbid condition(s) Complete tic remission is rare Stimulants are generally safe
