Movements or sounds that keep returning

Also called: functional tic disorder · functional tics

Functional tics are repetitive movements or vocalisations that are involuntary in the moment. They can appear quite suddenly, change over time, and sit alongside other FND symptoms.

How it can feel

  • Repeated movements of face, neck, shoulders or limbs.
  • Sounds, words or throat noises you did not plan to make.
  • A build-up of urge for some people; sudden bursts for others.
  • Tics that multiply when you are tired, observed or stressed.

Day to day

  • School and workplace concentration can suffer.
  • Social anxiety about being misread as deliberate disruption.
  • Pain from repeated movements in neck or jaw.

Understanding this FND symptom

Functional tics reflect a control problem in movement and inhibitory networks. They are not a performance. Assessment distinguishes them from other tic disorders.

What can help

  • Specialist assessment and a non-shaming explanation.
  • Therapy approaches used for tic disorders where appropriate.
  • Reducing sleep debt and sensory overload.
  • Supportive environments that do not punish the symptom.

FAQs

Did I cause my tics by watching videos?

Tics are multifactorial. Media exposure is sometimes discussed in research, but it does not mean you are faking or to blame.
