It started out of nowhere. You were already over 20 years old, had never had tics before, and suddenly your neck turns on its own, or a sound escapes uncontrollably.
Someone suggests “Tourette’s.” You look it up, but something doesn’t add up: Tourette’s begins in childhood, the tics develop gradually, and there’s a family history.
If your tics appeared suddenly in adulthood—especially after a period of intense stress or on social media—you may be dealing with functional tics, a manifestation of Functional Neurological Disorder (FND).
Functional Tics vs. Tourette’s: The Key Differences
| Characteristic | Functional tics (FND) | Tourette Syndrome |
|---|---|---|
| Age of onset | Late adolescence or adulthood | Childhood (ages 4–7) |
| Onset | Sudden (days or weeks) | Gradual (months or years) |
| Course | Fluctuating, may disappear | Chronic, with ups and downs |
| Type of tic | Complex, variable, bizarre | Simple, progressing to complex |
| Suggestibility | High (worsens when discussed) | Low |
| Distractibility | Improves with distraction | Little influence |
| Family history | Generally absent | Present in 50–80% of cases |
The Social Media Phenomenon
Since 2020, neurologists around the world have noted a significant increase in functional tics among adolescents and young adults—especially women.
The trigger? Videos of influencers with Tourette’s on TikTok and YouTube. Repeated exposure to this content, combined with social isolation and pandemic-related stress, has created a phenomenon of “social contagion” of tics—which are functional, not Tourette’s.
This does not mean that the person is “faking” it. The brain genuinely incorporates the observed motor pattern—a real neurological phenomenon, not simulation.
Treatment: Different Approaches for Each Condition
For Tourette’s:
- Behavioral Therapy (CBIT — Comprehensive Behavioral Intervention for Tics)
- Medication (clonidine, guanfacine, atypical antipsychotics)
- Long-term neurological follow-up
For functional tics:
- CBT with exposure and response prevention. The focus is on breaking the attention-tic-reinforcement cycle. See the evidence on CBT for functional tics.
- Hypnotherapy. Post-hypnotic suggestion and sensory grounding techniques are particularly effective for functional tics, which are highly suggestible by nature.
- Physical therapy with competitive strategies. This involves teaching movements that are incompatible with the tic to “compete” with the dysfunctional pattern.
- Trigger reduction. Identifying and limiting exposure to tic-related content on social media is an essential part of treatment.
Frequently Asked Questions
If my tics started after watching videos on TikTok, are they functional or Tourette’s?
Most likely functional—especially if you’re over 15 and have never had tics before. Genuine Tourette’s isn’t “acquired” from watching videos. But the diagnosis must be made by a specialized neurologist.
Can functional tics go away?
Yes. Unlike Tourette’s, functional tics have a high potential for complete remission with proper treatment. Many patients become tic-free within 2 to 4 months.
Does treatment for Tourette’s work for functional tics?
No. Medications used for Tourette’s generally do not work for functional tics—and can cause unnecessary side effects. The correct treatment is behavioral and psychotherapeutic, not pharmacological.
How can I tell if my child has Tourette syndrome or functional tics?
Tourette syndrome: onset before age 10, gradual progression, simple tics first (blinking, throat-clearing). Functional tics: sudden onset in adolescence, complex tics from the start, strong environmental influence. Read about how to explain FND to the family.
A wrong diagnosis means the wrong treatment—and years of frustration.
If your tics don’t fit the classic pattern of Tourette syndrome, it’s worth investigating the possibility of functional tics. Schedule a consultation. FND Hope and Neurosymptoms have information on the topic.
