NCT01177774

Brief Summary

The purpose of this research is to study why most children who have tics never develop Tourette syndrome but some do. In other words, we aim to find features that may predict whose tics will go away and whose tics will continue or worsen, in children ages 5 through 10 years whose first tic occurred within the past 9 months.

Outcome Measures

Primary Outcomes (1)

  • DSM-5 diagnosis of a chronic tic disorder at 12 months

    Research diagnosis of a chronic tic disorder at 12 months (cases), versus those whose tics are absent at 12 months (controls), will define two groups who will be compared on their baseline status (almost a year earlier) on a quantitative measure of functional connectivity maturity, pre-tic BOLD signal, caudate nucleus volume, and several clinical and neuropsychological measures.

    1 year after the onset of tics (6-12 months after the first study visit)

Study Arms (4)

Recent-onset tics that will persist

Children between 5 to 10 years of age with recent-onset tics (first tic occurred within the past 9 months) who, when reassessed at 1 year after the first tic began (i.e. 6-12 months after study enrollment) will turn out to meet criteria for a chronic tic disorder (including Tourette syndrome). Scheduled follow-up visits will include children over age 10 (initially enrolled at age 5-10).

Recent-onset tics that will remit

Children between 5 to 10 years of age with recent-onset tics (first tic occurred within the past 9 months) who will no longer have tics when reassessed 1 year after the first tic began (6 to 12 months after study enrollment). Scheduled follow-up visits will include children over age 10 (initially enrolled at age 5-10).

Tic-free control subjects

Children with no current or past tic disorder of similar age, sex and handedness as the children in the recent-onset tics groups.

Existing TS/CTD

Children with current tics whose first tics were more than 12 months ago (DSM-5 Tourette's Disorder or Persistent \[Chronic\] Motor or Phonic Tic Disorder), of similar age, sex and handedness as the children in the recent-onset tics groups.

Eligibility Criteria

Healthy VolunteersNo
Age GroupsChild (0-17)
Sampling MethodNon-Probability Sample
Study Population

1. A convenience sample of children age 5-10 who have tics now but whose first-ever tic occurred within the past 9 months. Subjects will be a convenience sample from community and clinical sources. 2. A control group who already meets criteria for a diagnosis of a chronic tic disorder, matched for age, sex, handedness, and ADHD 3. A control group who has no tics, matched for age, sex, handedness, and ADHD

You may qualify if:

  • Age 5-10
  • Informed consent from a parent and assent from the child.
  • New Tics Group \*\*
  • tics now, but developed them only in the past 9 months.

You may not qualify if:

  • \*\* Existing TS/CTD control group \*\*
  • children who meet DSM-5 criteria for Tourette's Disorder or Persistent Tic Disorder at enrollment
  • matched to children from the New Tics group on age (within 1 year), sex, handedness, and ADHD status.
  • \*\* Tic-free controls \*\*
