Tourette syndrome is not something you can “make yourself get” on purpose; it usually develops because of a mix of genetic vulnerability and brain differences, sometimes influenced by early-life environmental factors.

What Tourette’s Actually Is

Tourette’s is a neurological (brain-based) condition where a person has multiple motor tics (movements) and at least one vocal tic (sounds) for over a year, usually starting in childhood.

These tics are involuntary or only partly controllable, even if the person can sometimes hold them in for short periods.

How Do You “Develop” Tourette’s?

1. Genetics: You’re Born With the Risk

Most people who develop Tourette’s were born with genes that raise their risk.

  • Tourette’s is highly heritable; close family members are much more likely to also have tics or Tourette’s.
  • There is no single “Tourette gene”; many genes each contribute a small effect.
  • Some rare mutations in genes like SLITRK1, NRXN1, and CNTN6 have been linked to Tourette’s in a small number of people.

So you don’t “catch” Tourette’s later in life like an infection; you’re generally born with a predisposition, and symptoms show up as your brain develops.

2. Brain Circuits and Chemicals

Research suggests that Tourette’s involves differences in brain circuits that help control movement and habit formation.

  • Key regions: basal ganglia, thalamus, and frontal cortex.
  • Neurotransmitters involved: dopamine, serotonin, GABA, glutamate, histamine, and others.
  • These differences seem to make it harder for the brain to filter out urges to move or make sounds, so tics “break through.”

You don’t cause these brain differences by behavior or personality; they’re part of how your nervous system develops.

3. Environmental and Early-Life Factors

Genes aren’t the whole story. Having a vulnerability doesn’t guarantee you’ll develop Tourette’s.

Studies suggest some factors may slightly raise risk if the genetic predisposition is already there:

  • Issues during pregnancy: severe stress, certain infections, tobacco/alcohol use, or complications like severe nausea (hyperemesis).
  • Birth and newborn factors: premature birth, low birth weight, low Apgar scores.
  • Possibly immune or inflammatory factors and environmental toxins, though this research is still evolving.

These are risk modifiers , not direct causes; plenty of children with these factors never develop Tourette’s, and many with Tourette’s never had obvious complications.

What You Can’t Do: “Give Yourself” Tourette’s

Common misconceptions:

  • You cannot develop Tourette’s just by:
    • Swearing a lot
    • Copying tics as a joke
    • Watching people with Tourette’s online
    • Being “too stressed” as an otherwise healthy adult
  • Stress, anxiety, and tiredness can worsen existing tics , but they do not create the underlying condition in someone without that vulnerability.

There are stress-related or “functional” tic-like behaviors that can appear suddenly (often in teens, sometimes after social media exposure), but those are different from classic, childhood-onset Tourette’s and follow different mechanisms and treatment approaches.

When Tourette’s Usually Starts

  • Tics typically begin between ages 2 and 15, with an average around 6 years old.
  • They often start as simple motor tics (like blinking or facial movements) and can evolve over time.
  • Many people see their tics improve in late teens or early adulthood.

Adult-onset tics are uncommon and often trigger a careful evaluation to rule out other conditions or functional (non-structural) disorders.

Aspect What We Know
Primary cause Combination of genetic predisposition and brain circuit differences.
Can you “cause” it yourself? No; you can’t will or learn yourself into true Tourette’s.
Role of environment Pregnancy/birth complications, immune factors, and toxins may slightly modify risk when genes are present.
Typical age of onset Childhood, usually between 2–15 years, average around 6.
What makes tics worse Stress, anxiety, excitement, fatigue, and sometimes stimulants can increase tic severity.

If You’re Worried About Yourself (or Someone Else)

If you or someone you know has new or worsening tics:

  1. Track what you’re seeing
    • Note when tics started, how often they happen, and what seems to trigger or calm them.
  1. Talk to a medical professional
    • A GP, pediatrician, neurologist, or psychiatrist can evaluate for Tourette’s or other tic disorders.
  1. Ask about treatment and support
    • Options might include behavioral therapies for tics, school/work accommodations, and sometimes medication if tics are very disruptive.

Story-Style Illustration (Very Short)

Imagine two kids in the same class. Both see TikToks of people with Tourette’s and start imitating tics as a joke. One stops after a day. The other realizes he’s actually been blinking and jerking his head for months but tried to ignore it. Over time, his tics grow stronger, especially when exams are coming up. A doctor later explains that he likely had a genetic predisposition and that stress is making his existing tics more obvious—not that the videos “gave” him Tourette’s.
