Article Synopsis
  • Behavioral therapies, like comprehensive behavioral intervention for tics (CBIT), habit reversal therapy (HRT), and exposure and response prevention (ERP), are recommended as the first-line treatment for Tourette syndrome and tic disorders.
  • Research shows that face-to-face CBIT is effective, and videoconferencing can deliver similar benefits; however, group treatments may not be as effective as individual therapy.
  • There are promising findings for internet-based therapies, and ongoing efforts aim to enhance access to these behavioral treatments for those with tic disorders.

Article Synopsis
  • A study conducted on Huntington's disease (HD) in Latin America found that previous global reviews have overlooked significant regional data, prompting a search across Spanish, Portuguese, and English databases to gather relevant studies.
  • The research identified 24 studies from 12 of the 36 Latin American countries, revealing a pooled prevalence of HD at 0.64 per 100,000 people, with higher rates specifically in Mexico, Peru, and Brazil.
  • The authors suggest that the actual prevalence of HD may be underestimated due to limited research, underdiagnosis, and insufficient access to molecular testing and specialists in the region, emphasizing the need for further studies to enhance understanding and access to care.

Article Synopsis
  • * Researchers compared the premonitory urge for tics scale (PUTS) scores between 83 tic patients and 40 FTLB patients, finding no significant differences.
  • * The results suggest that FTLB patients experience PU with similar frequency and intensity as those with tics, indicating PU is not effective in distinguishing between the two conditions.

Article Synopsis
  • The study examines functional tic-like behaviors (FTLB), primarily affecting females, and notes a rise in cases during the COVID-19 pandemic, comparing them to individuals with Tourette Syndrome (TS) and neurotypical (NT) peers.
  • Participants with FTLB displayed significantly higher rates of psychiatric disorders, including major depressive disorder and anxiety issues, and reported a further decline in mental health during the pandemic compared to TS and NT groups.
  • FTLB participants also experienced more challenges like loneliness and trouble with basic needs, and a higher prevalence of identifying as gender minorities, though no gender differences were found within the FTLB group itself.

Article Synopsis
  • A study was conducted to evaluate the effectiveness of specific criteria set by the European Society for the Study of Tourette Syndrome (ESSTS) for diagnosing functional tic-like behaviors (FTLBs) in children and adolescents with tic disorders.
  • The analysis involved assessing the phenomenological characteristics of tic disorders using the Yale Global Tic Severity Scale on participants collected in Calgary, Canada, over specific years.
  • Results showed that the ESSTS criteria demonstrated high specificity, particularly regarding age of onset and presence of complex tics, suggesting their usefulness in clinical diagnosis of FTLBs.

Article Synopsis
  • Tics are involuntary and repetitive movements or sounds that differ from compulsive behaviors, and they have unique features such as a premonitory urge and ability to be suppressed.
  • Tourette syndrome (TS), which is common in school-aged boys, is characterized by multiple motor and vocal tics over a year and is highly heritable, often accompanied by mental health issues like ADHD and OCD.
  • Treatment for tics includes behavioral therapies and medication, with deep brain stimulation as an option for severe cases; most individuals experience a reduction in tic severity by adulthood.

Introduction: Eight members of the International Parkinson's Disease and Movement Disorders Society Tic and Tourette Syndrome Study Group formed a subcommittee to discuss further barriers to practice guideline implementation. Based on expert opinion and literature review, the consensus was that practice variations continue to be quite broad and that many barriers in different clinical settings might negatively influence the adoption of the American Academy of Neurology and the European Society for the Study of Tourette Syndrome published guidelines.

Objectives: 1) To identify how clinical practices diverge from the existing American Academy of Neurology and European Society for the Study of Tourette Syndrome guidelines, and 2) to identify categories of barriers leading to these clinical care gaps.

Background And Purpose: Developmental stuttering and Tourette syndrome (TS) are common neurodevelopmental disorders. Although disfluencies may co-occur in TS, their type and frequency do not always represent pure stuttering. Conversely, core symptoms of stuttering may be accompanied by physical concomitants (PCs) that can be confused for tics.

Background: Youth and parent engagement is a key component of clinical research. There are many ways to actively and meaningfully engage youth and parents as integral members of research teams, for example, through ad-hoc committees, advisory councils, or as co-leads on projects. When youth and parents are actively and meaningfully engaged in research projects, they share knowledge from their lived experiences to improve the quality and relevance of research.
