Brain functional connectivity in Tourette syndrome
(Elsevier) Tourette syndrome, a neurodevelopmental disorder, causes motor and phonic " tics, " or uncontrollable repeated behaviors and vocalizations. People affected by Tourette syndrome can often suppress these tics for some time before the urges become overwhelming, and researchers have long wondered at the neural underpinnings of the suppression effort. In a new study, researchers at Yale School of Medicine have assessed the impact of tic suppression on functional connectivity between brain regions.

Conclusion: Patients with TS display deficits of white matter microstructure in the CC and right ILF known to be important for interhemispheric connections as well as long association fiber bundles within one hemisphere. Because the results reported in the primary literature were highly variable, future investigations with large samples would be required to support the identified white matter changes in TS.
To determine the long-term durability of behavior therapy for tics among youth with Tourette ’s disorder and persistent (chronic) motor or vocal tic disorders.
This report presents a case of TS reemergence against the background of immunological reaction or PANDAS with a late adolescent onset.

Tourette syndrome is a childhood-onset neurodevelopmental disorder characterized by motor and vocal tics. On the neural level, tics are thought to be related to the disturbances of the cortico-basal ganglia-thalamo-cortical loops, which also play an important role in procedural learning. Several studies have investigated the acquisition of procedural information and the access to established procedural information in TS. Based on these, the notion of procedural hyperfunctioning, i.e., enhanced procedural learning, has been proposed. However, one neglected area is the retention of acquired procedural information, especially...
J Diet Suppl. 2021 Aug 11:1-16. doi: 10.1080/19390211.2021.1958120. Online ahead of print.ABSTRACTVery little is known about the use of nutritional supplements in children with Tourette syndrome. The current study aimed to address the frequency of nutritional supplements and the use of special diets in children with Tourette syndrome and typically developing children. Additional data also sought to address the motivations behind using them, their cost and perceived benefits. A total of 76 responses from an anonymous online survey (Tourette syndrome = 42; typically developing = 34) were completed and analyzed. Fifty-six per...
AbstractThe formation of a new umbrella organisation called Tics and Tourette Across the Globe (TTAG) representing Tic and Tourette Syndrome (TS) patient associations around the world has led to a clearer voice for patients with Tourette Syndrome (TS). An opportunity has been created for this group to bridge research, clinical work and shared decision-making between researchers, clinicians and patients across Europe, with the result of improving the treatment and management of TS. A survey was sent out to capture the patients ’ perspective on research and treatment, and 2269 participants responded. 71% of participant...
This study explored the role of self-esteem in mediating the relationship between psychosocial stress and social adjustment among adolescents with Tourette syndrome, and the role of comorbidities in moderating the relationship between self-esteem and social adjustment.
