environmental triggers for tics

“Tics wax and wane. It’s just the nature of the beast.”

Or is it?  Some experts are beginning to believe that the waxing and waning effect is not random but is instead related to environmental factors—many of which we have control over. 

Although there are no controlled trials studying triggers, surveys from parents and treatment centers that see large populations of children with tics reveal certain environmental factors that appear to make tics worse.  And while some are universal (like video games or computer use), others might apply only to certain individuals (like a food allergy). 

Here are some common triggers.  Try eliminating each one for two to three weeks to see if it makes a difference.

1.  Electronic screen media—since video games and computer use increases dopamine and tics are dopamine-related, it’s understandable that electronic media worsens tics.  For bothersome tics, I recommend a three week “electronic fast” to normalize brain chemistry and improve sleep (restful sleep improves tics in and of itself).

2. Food, chemical, and seasonal allergies or sensitivities—there are two ways to assess for sensitivities.  Testing, and systematic elimination.  Testing can increase compliance, but sometimes an individual will test negative for a particular offender but nevertheless see improvement with the offender removed.  By the way, your doctor needs to test for IgG for sensitivities, which are delayed reactions, not just IgE, which are immediate reactions.  Labs like Metametrix specialize in this kind of testing at a reasonable cost.  Here are some common sensitivities:
 

  • Gluten-gluten is hard to digest and may cause the gut to “leak”, introducing other allergens that irritate the brain.  Notably, some individuals test negative for the IgG antibody to gliadin, but nevertheless see symptom improvement with gluten removed from the diet.
  • Dairy-since dairy can thicken mucus, verbal tics in particular may improve when dairy is eliminated.  Again, this is worth trying even when tests don’t reveal any allergy or sensitivity.
  • Dust and pollen-try an air purifier with a HEPA filter.  Anti-allergy medications may also help.
  • Preservatives, dyes, and artificial sweeteners/flavors-these are good to get rid of in general, but confirmation through testing can convince you it’s worth the inconvenience.
  • Sugar and refined carbohydrates—sugar causes an immediate cascade of inflammatory events throughout the whole body, including the brain.  (Blood sugar sensitivies are a different kind of testing.)
  • Caffeine – you don’t need to test for this one.  Just get rid of it! Caffeine is a stimulant and can decrease blood flow to the brain.

3.  ADHD medications—stimulants, Strattera, and Wellbutrin can all worsen tics—but not in every case.  Unfortunately many children with tics also have ADHD, rendering the ADHD difficult to treat.  However, removing offenders outlined in this article can help both conditions.

4.  Fluorescent lights—as incandescent lights are phased out and replaced with energy saving fluorescents, this may be one reason that tics are on the rise.  Flourescent lights flicker (yes, even the “non-flicker” kind still flicker) and emit more radiation—both of which irritate the nervous system.  Stock up on regular old incandescents if you can; halogen incandescents are second-best.  LEDs are less irritating than CFLs but still worse than halogens. 

5.  Streptococcal infections (PANDAS)-Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococci are a group of disorders in which the antibody created against Strep bacteria cross-reacts with the basal ganglia in the brain--causing tics, movement disorders, and/or OCD.  Since PANDAS-related tics may respond to antibiotics or tonsillectomy, it’s worth checking testing for.
