How to diagnose and treat Tourette syndrome?
There’s no specific test that can diagnose Tourette syndrome. The diagnosis is based on the history of your signs and symptoms.
The criteria used to diagnose Tourette syndrome include:
- Both motor tics and vocal tics are present, although not necessarily at the same time
- Tics occur several times a day, nearly every day or intermittently, for more than a year
- Tics begin before age 18
- Tics aren’t caused by medications, other substances or another medical condition
To rule out other causes of tics, your doctor might recommend:
- Blood tests
- Imaging studies such as MRI
There’s no cure for Tourette syndrome. Treatment is aimed at controlling tics that interfere with everyday activities and functioning. When tics aren’t severe, treatment might not be necessary.
Medications to help control tics or reduce symptoms of related conditions include:
- Medications that block or lessen dopamine.
- Botulinum (Botox) injections.
- ADHD medications.
- Central adrenergic inhibitors.
Therapies used to control tics or reduce symptoms of related conditions include:
- Behavior therapy.
- DBS. DBS involves implanting a battery-operated medical device in the brain to deliver electrical stimulation to targeted areas that control movement.
