Objective
Tourette syndrome (TS) is a neurodevelopmental disorder characterized by the presence of motor and phonic tics. Blocking phenomena, characterized by arrests in motor activity causing interruptions in movements or speech, have also been described in patients with TS. In this study, we aimed to characterize the frequency and features of blocking tics in patients with TS.
Methods
We studied a cohort of 201 patients with TS evaluated at our movement disorders clinic.
Results
We identified 12 (6%) patients with blocking phenomena. Phonic tic intrusion causing speech arrest was the most common (n = 8, 4%), followed by sustained isometric muscle contractions arresting body movements (n = 4, 2%). The following variables were statistically related to blocking phenomena: shoulder tics, leg tics, copropraxia, dystonic tics, simple phonic tics, and number of phonic tics per patient (all p < 0.050). In the multivariate regression, the presence of dystonic tics (p = 0.014) and a higher number of phonic tics (p = 0.022) were associated with blocking phenomena.
Conclusion
Blocking phenomena are present in approximately 6% of patients with TS, and the presence of dystonic tics and a higher frequency and number of phonic tics increase the risk for these phenomena.

AbstractAbstract PDFSupplementary Material
Objective
In patients with Tourette syndrome and other primary tic disorders (PTDs), tics are typically preceded by premonitory urges (PUs). To date, only a few studies have investigated the location and frequency of PUs, and contrary to clinical experience, the results suggest that PUs are not located in the same anatomic region as the tics. This study aimed to further explore PU location and frequency in detail, differentiating the kind and complexity of the corresponding tics, in a large sample of patients with PTD.
Methods
A total of 291 adult (≥ 18 years) patients with a confirmed diagnosis of chronic PTD were included. The study was conducted online, assement included tics and the general characterization of PUs and a sophisticated body drawing for locating PUs.
Results
We found that PUs were located in the same body area as, or in direct proximity to, the corresponding tic. Most frequently, PUs were located in the face and at the head (62.1%). Compared with simple tics, complex (motor and vocal) tics were more often preceded by a PU; but there was no difference in PU frequency observed between motor tics and vocal tics. PUs were more often experienced at the front than at the back of the body (73% vs. 27%), while there was no difference between the right and left sides (41.6% vs. 41.3%).
Conclusion
The strong association between PU and tic location further supports the hypothesis that PUs represent the core of PTD. Accordingly, future therapies should focus on treating PUs to achieve greater tic reduction.

AbstractAbstract PDF

Hoarseness and dysphonia are often a result of vocal cord polyps which in turn, are linked to vocal trauma. We report the case of vocal polyps in the setting of a 27-year old male with a history only remarkable for Tourette syndrome. We review the literature regarding etiology and pathophysiology of vocal cord lesions and propose vocal tics in Tourette syndrome as an under-recognized etiology. In this way, we also review therapies that may aid in treating not only the vocal cord lesions but also particularly in the setting of vocal tics.
