Overview

Persistent (Chronic) Motor or Vocal Tic Disorder involves either motor or vocal tics, but not both, that have been present for more than a year since the first tic onset, typically beginning in childhood.

Signs and Symptoms

Motor tics can include blinking, shoulder shrugging, or other sudden repetitive movements; vocal tics can include throat clearing or other repetitive sounds, and tics often wax and wane in frequency and intensity. Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.

Causes and Risk Factors

Tic disorders have a genetic component and are associated with differences in brain circuits involved in movement regulation; stress and fatigue can increase tic frequency.

Diagnosis

A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment. Other causes of tics, including certain medications or medical conditions, are typically considered as part of the evaluation.

Treatment

Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.

Psychotherapy

Comprehensive behavioral intervention for tics (CBIT), which builds awareness and a competing response, is a well-supported treatment.

Medication

Medication may be considered if tics are significantly impairing, though many people manage well without it.

Living With Chronic Tic Disorder

Managing stress, ensuring adequate sleep, and using learned behavioral strategies can help reduce tic frequency and impact.

When to Seek Professional Help

Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.

Outlook

For many people, tics decrease in frequency and severity by late adolescence or adulthood, and most manage well with behavioral strategies and support.
