What they are
Tic disorders involve sudden, rapid, recurrent, nonrhythmic movements or vocalizations:
- Provisional Tic Disorder: tics < 1 year
- Persistent (Chronic) Motor or Vocal Tic Disorder: motor or vocal tics ≥ 1 year
- Tourette Syndrome: both motor and vocal tics for ≥ 1 year, onset before 18
Tics often wax and wane, increase with stress/excitement, and decrease with focused activities. Many improve in late adolescence. Tics are not “on purpose.”
Common signs and symptoms
- Motor tics: eye blinking, facial grimacing, head jerks, shoulder shrugs, tapping
- Vocal tics: throat clearing, sniffing, grunts, words or phrases (coprolalia is uncommon)
- Premonitory urge: uncomfortable sensation relieved temporarily by the tic
- Co-occurring conditions: ADHD, OCD, anxiety, learning differences, sleep issues
Why they happen
- Neurodevelopmental differences in circuits controlling movement and inhibition
- Genetic factors; family history common
- Stress, fatigue, illness can transiently worsen tics
What helps
- First-line behavioral therapy
- CBIT (Comprehensive Behavioral Intervention for Tics): habit reversal training (awareness + competing response), function-based interventions; strong evidence
- Medications (when needed)
- Alpha-2 agonists (guanfacine, clonidine) helpful for mild–moderate tics and co-occurring ADHD
- Antipsychotics (e.g., aripiprazole, risperidone) for severe tics; monitor side effects
- Botulinum toxin for focal painful tics; in refractory adult cases, DBS is rare
- School/work strategies
- Education to reduce stigma; breaks for tics; seating preferences; test accommodations
- Lifestyle
- Sleep regularity, stress management, exercise
- Reduce stimulants when feasible if they aggravate tics; balanced ADHD treatment if co-occurring
Treat only when tics cause pain, social/academic problems, or distress. Many do well with education and CBIT alone.
When to seek help now
- Tics causing self-injury, severe pain, or major school/work disruption
- Sudden dramatic tic onset with other neurologic symptoms (seek medical evaluation)
- Depression, bullying, or thoughts of self-harm
How to talk to a clinician
- “I (or my child) have motor/vocal tics for over a year. We’d like CBIT and guidance on school accommodations; please assess for ADHD/OCD.”
