NCT03851484

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.

Outcome Measures

Primary Outcomes (3)

  • Baseline Sensory Perception Quotient score, short form

    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.

    Initial assessment at enrollment (time zero)

  • Change in Sensory Perception Quotient score, short form at 1 year

    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.
