Overview
Brief Summary
Patients with tics will be asked to complete a series of validated questionnaires (in electronic and/or paper format) regarding symptoms and conditions often associated with Tourette syndrome, including premonitory urges, sensory experiences, inattention, obsessive-compulsive tendencies, anxiety, and depression. Participants will also be asked to complete a quality of life assessment. This series of questionnaires will be administered annually.
Detailed Description
Patients with tics will be recruited to participate in an observational study assessing extent and variation in non-motor features of Tourette syndrome over time. Each participant will complete a battery of validated questionnaires and scales online or in paper format (per patient preference), including the Premonitory Urge to Tic Scale (PUTS), the Sensory Gating Inventory (SGI), the Sensory Perception Quotient, the ADHD Self-Report Screening Scale, and others. These questionnaires will be administered annually to patients. For the analysis, participants will be stratified by age into late adolescents (18-25 years old) and adults (older than 25 years) since adolescent development ends at approximately age 25.

Eligibility Criteria
Inclusion Criteria

- •Ability to provide informed consent and answer self-report questionnaires independently in English

Outcomes
Primary Outcomes
Baseline Sensory Perception Quotient score, short form
Time Frame: Initial assessment at enrollment (time zero)
Validated instrument assessing anomalous sensory experiences. Scale consists of 35 items screening patients for hyper- or hypo-sensitivity to each of the sensory domains (touch, sight, sound, smell, and taste). Each scale item is a statement to which participants provide a ranking: 0 = strongly agree 1. = agree 2. = disagree 3. = strongly disagree The minimum score on the short from is 0; the maximum score is 140. Higher scores indicate more abnormal sensory experiences.
Change in Sensory Perception Quotient score, short form at 2 years
Time Frame: 2 years
