Purpose and Suitability

Use this guide to describe movement and sound, onset and change over time before deciding whether symptoms are primary tics, functional tic-like symptoms, another disorder or a combination. A tic/FND-experienced clinician should explain the formulation. 1, 2

Phenomenology: The description of what a symptom looks or sounds like, and how it behaves.

Anatomy and Physiology

Motor symptoms are movements; vocal or phonic symptoms are sounds, including sounds without words. An urge and the ability to delay a symptom do not give direct access to its cause. The original inventory explains why urges, variability, suppressibility and suggestibility cannot independently separate primary and functional presentations.

Preparation and Safety

Ask whether discussing or hearing symptoms increases them. Offer a quiet room, breaks, written answers and communication support. Avoid symptom montages, offensive phrase examples and requests to demonstrate or suppress symptoms. Obtain consent for collateral accounts and recordings; protect the person’s intended communication.

Performing the Assessment

Authored consultation sequence

Establish the first movements and sounds, age at onset, speed of change and subsequent course. Distinguish “first noticed” from “first remembered”.
Ask about earlier childhood symptoms and available records without assuming recall is complete. Record any established primary tic disorder separately.
Describe current movements and sounds, simple or complex patterns, clustering, injury and interruptions to activity. Avoid interpreting the meaning of involuntary words as intent.
Ask about sensations, temporary delay, effort and what happens afterwards. Use ordinary history rather than a prolonged suppression challenge.
Review relevant medications, neurological findings and alternatives such as stereotypies, compulsions, jerks or speech/voice disorders.
Record which aspects remain uncertain and the next assessment or follow-up step.

This sequence organizes the existing assessment domains; it is not a diagnostic scoring system. 1, 2

Interpreting Findings

A feature becomes useful through its relationship to the whole history, examination and competing explanations. Demographics, psychiatric history, autism, ADHD or social-media exposure are not standalone diagnostic evidence. Primary tics and functional symptoms may coexist; do not force every sound and movement into one category. 1

A recording captures a selected period. It does not measure the whole person’s control, daily burden or behaviour when unobserved.

Explaining the Result

Authored explanation example: “We are considering the history and the pattern together. Some features may belong to an earlier tic disorder and others may need a different explanation. The symptoms are involuntary, and uncertainty does not prevent us from helping with their impact.”

Evidence and Limitations

The review provides clinical synthesis, not a validated checklist. The assessment guideline concerns primary tic disorders and is adjacent evidence; it does not validate a functional-tic classifier. This guide retains their established assessment domains while keeping the criteria and uncertainty discussion separate. 1, 2

Media and Accessibility

Use a fictional consultation or static diagram, with captions and a full text equivalent. Show routes for motor symptoms, vocal symptoms and coexistence. Explain why history and longitudinal assessment matter. Avoid symptom montages, provocative exercises, offensive example phrases and any visual suggestion that movement shape alone distinguishes diagnoses.
