Tics: Tips & Tricks
 Education is often the only treatment needed
 Don’t forget about the comorbid conditions
 Shift in the way we think about tics
 Ignore vs. Increase awareness?
Brad Cohen
(Bennett et al., 2013)
Trichotillomania (TTM)
TTM (Hair-Pulling Disorder)
DIAGNOSTIC CRITERIA
DSM
4-TR
DSM
5
Recurrent pulling out of one’s hair resulting in hair loss
√
√
Increasing sense of tension immediately before pulling out the hair /
when attempting to resist behavior
√
Pleasure, gratification, or relief when pulling out the hair
√
DSM 4TR – Impulse Control Disorders Not Elsewhere Classif.
DSM-5: Obsessive Compulsive Disorders & Related Disorders
Repeated attempts to decrease or stop hair pulling.
√
The disturbance (hair pulling- DSM 5) is not better accounted for by
another mental disorder and is not due to a general medical
condition (e.g., a dermatological condition)
√
√
The disturbance (hair pulling- DSM 5) causes clinically significant
distress or impairment in social, occupational, or other important
areas of functioning
√
√
The hair pulling is not better explained by the symptoms of another
mental disorder (e.g., attempts to improve a perceived defect or flaw
in appears in body dysmorphic disorder)

TTM -Rituals
 Tactile stimulation of lips or face.
 A need to pull in a particular manner.
 Ritualistically placing, saving, or discarding hairs.
 Twirling, rolling, or examining the hair.
 Hairs that don’t feel right (i.e. coarse).
 Hairs that don’t look right (i.e. color).
 Compelled to achieve an absolutely even hairline.
 Need to extract an intact hair bulb.
 Need to bite or mince the hair or bulb
 Swallowing hair (trichophagy)

TREATMENT
 Cognitive Behavioral Therapy
 Identify
distorted thinking and challenge
thoughts
 Relaxation training
 Behavioral – Habit Reversal
Training
Treatment
 Habit Reversal Training
Competing response
TREATMENT STEPS
 Monitoring of Symptoms (pulling/picking)
 CBT Intervention:
 Cognitive restructuring, coping thoughts
 Relaxation exercises, stress management
 Tactile Interventions:
 Finger tip bandages, gloves, bracelets, glasses, hats, etc.
 Silly putty, thinking putty, worry beads, soft brush
 Sensory Interventions:
 Numbing cream, brushing hair
 Gummy bears, sunflower seeds, dental floss, Khoosh balls, frayed
blankets, smurfs
 Environmental Interventions:
 Removing tweezers, covering mirrors
 Habit Reversal Training:
 Awareness training, stimulus control, competing response
CASE: “EMILY”
Initial Assessment:
 10 year old; intact family
 6 month history of eyelash pulling; no eyelashes at
assessment
 Several year history of nail biting
 Stressors:


Increased parental conflict
Bullying incident at school; largely resolved.
 Good student
 No comorbid anxiety or mood issue
CASE: “EMILY”
 Family History:
 Father suffers from OCD
 Recommendations:
 “focus on catching herself when urge to pull”
 “talking to parents”
 “relaxation tapes”
 “marital therapy”
 Result: Limited Effectiveness
CASE: “EMILY”
 NOW 13 years old … REASSESSMENT
 Lash pulling waxed and waned x 3 years
 Currently no lashes
 Parents used rewards with variable effectiveness
 Emily expressed high motivation to change
 Some anxiety in social situation (secondary to trich)
 PLAN:
 CBT + Monitoring + Habit Reversal Training
CASE: “EMILY”
CASE: “EMILY”
 16 sessions CBT + Habit Reversal Training
 Session 5: eyelash regrowth
 Session 7: “more confident”
 Session10: healthy lashes
 Session 13: no pulling
 Follow-up: 2 months later pulling apparent
 Follow-up: 4 months later no pulling/picking
 Seen in periodic follow-up: 2 years later no
pulling/picking
TTM – Keys to Successful Outcomes
 Thorough and knowledgeable assessment
 Emphasize treatment is a process
 Motivational for change
 Use of first line treatments:
 Cognitive
Behavioral (CBT) and
Habit Reversal Training
Obsessive-Compulsive
Disorder (OCD)
Meet Claire
OCD: Assessment & Diagnostic Issues
Obsessions and/or compulsions that take up
more than an hour a day and cause significant
distress or impairment
 Obsessions
 Recurrent and persistent thoughts, urges, or
images that are intrusive and unwanted
 Compulsions
 Repetitive behaviors or mental acts that one
feels driven to perform in response to an
obsession or according to rules
OCD: Assessment & Diagnostic Issues
 Common themes:




Contamination and cleaning
Checking or symmetry
Ordering or counting
Fear of harm to self or others
 Lifetime prevalence = approx. 2%, chronic, fluctuates
 Mean age of onset is bimodal  peaks at 11 and 23 years
 Early-onset OCD



1st Peak
Age 11

More likely comorbid with tics
Generally more severe

Cognitive Behavioural Therapy (CBT)
 Controlled studies support the efficacy of Cognitive
Behavioural Therapy (CBT) that emphasizes
Exposure and Response Prevention (ERP)
 Parental involvement is crucial for success
Parents do not
accept symptoms
Child not responsible

CBT for OCD: Critical Components
Treatment Component
Operational Definition
Psychoeducation
Both the child and the family need to have an
accurate understanding of OCD
Symptom Monitoring
Identify/track sx frequency and duration; Set targets
to work towards
Relaxation Training
Deep Breathing, Muscle Tension Relaxation,
Imagery
Cognitive Strategies
Generate and reinforce accurate thoughts to
challenge obsessions and compulsions
Exposure & Response
Prevention (ERP)
Confronting an OCD-eliciting situation (action,
object, place, etc.) while preventing the associated
compulsions and/or avoidance
Homework
Change cannot occur exclusively through CBT
sessions; strategies must be practiced at home
Childhood OCD: Tips & Tricks
 Childhood and adult OCD are more similar than
not. However, some differences exist :

Obsessions develop later that compulsions

Poor insight is more common in children

Children tend to under-estimate the impact of their OCD

Children are more likely to present with comorbid OCD and
tics

Similarities vs. Differences
 8 statements on the next 2 slides
Decide whether statement is a similarity
(applicable across the RBs discussed – OCD, TTM, TS)
or
whether it is a difference
(applicable to 0,1 or 2 but NOT all RBs discussed)
Similarities vs. Differences
(1) Behaviour done in response to a sensation
(2) Comorbidities are common & frequent
(3) Competing responses are part of treatment
(4) Onset usually before age 10
Similarities vs. Differences
(5) Symptoms wax and wane
(6) Personal distress required for treatment
(7) More common in males
(8) Medications could be useful

An Analogy for Understanding RBs
Brake Shop Model
Welcome to the Leaky Brake Club
 Leaky brakes over movements and/or sounds (TICS)
 Leaky brakes over thoughts (OCD)
 Leaky brakes over urges (TTM)
 Leaky brakes over attention +/or impulsivity (ADHD)
 Leaky brakes over behaviour (ODD, CD, rage)
 Leaky brakes over senses (Sensory integration disorder)
Welcome to the Leaky Brake Club!!
YOU = Driver
Welcome to the Leaky Brake Club!!
Welcome to the Leaky Brake Club!!
Welcome to the Leaky Brake Club!!
Welcome to the Leaky Brake Club!!
UH –OH!!!!
Welcome to the Leaky Brake Club!!
UH –OH!!!!
You Say….
BUT I DIDN’T DO IT!
 I TRIED TO STOP
 THE BRAKES DIDN’T WORK…
 I’m not a reckless individual.
 I shouldn’t lose my drivers licence.
Now imagine you had to drive
around in a car that had leaky
brakes ALL the time.
Wouldn’t YOU be frustrated?
Take Home Messages
 Leaky Brakes = Help child understand RB
 Society: “Just Stop” vs. Patient: “I would if I could”
 Awareness of behaviour & reinforcement patterns
 RBs = a spectrum
 Function of behaviour important differential
 More research needed!
