What is Tourette Syndrome?

Tourette syndrome is a neurological condition that causes repeated movements or sounds called tics. These tics happen involuntarily, which means a person cannot fully control them. Some tics are mild and barely noticeable, while others may affect daily activities or social interactions.

Experts believe genetics play a major role in Tourette syndrome. A family history of tics or Tourette syndrome may increase risk. The condition is more common in males, and environmental or developmental factors may also contribute.

Symptoms often begin during childhood, but Tourette syndrome can continue into adulthood. Many people notice that their tics change over time, and some experience fewer symptoms as they get older.

Symptoms

Tourette syndrome affects each person differently. Tics may come and go, and their severity can change over time.

Common symptoms include:

• Frequent blinking or facial movements
• Head jerking or shoulder shrugging
• Sudden arm, leg, or body movements
• Repeated throat clearing or sniffing
• Grunting, coughing, or squeaking sounds
• Repeating words or sounds
• Movements or sounds that increase during stress or excitement

Many people with Tourette syndrome also experience related conditions such as:

• Attention-deficit/hyperactivity disorder (ADHD)
• Obsessive-compulsive disorder (OCD)
• Anxiety or depression
• Sleep problems
• Social or learning challenges

How is it diagnosed?

There is no single test for Tourette syndrome. Healthcare providers diagnose the condition by reviewing symptoms, medical history, and how long tics have been present.

An evaluation may include:

• A physical and neurological exam
• Questions about motor and vocal tics
• Family history review
• Behavioral or psychological assessment

In some cases, imaging or lab tests may be used to rule out other neurological conditions.

How is it treated?

Treatment depends on how much symptoms affect daily life. Some people with Tourette syndrome have mild symptoms and may not need medical treatment.

For people who need additional support, treatment options may include:

• Behavioral therapy, including Comprehensive Behavioral Intervention for Tics (CBIT)
• Counseling or mental health support
• Medications to reduce tic severity
• Treatment for related conditions such as ADHD, OCD, anxiety, or depression
• School or workplace accommodations to improve daily functioning

Tourette syndrome is a lifelong condition, but symptoms often improve during the late teen years or adulthood. Many people lead active, healthy lives with proper support and treatment.
