  • Case Report

    Open Access•Charlotte Marie Streetz, Natalia Szejko et al.•ARTICLE•Frontiers in Psychiatry•2025

    This case study demonstrates that patients with TS plus comorbid ADHD may be fit to drive even after intake of high doses of MC. In any case, however, every driver, who uses MC, is obliged to check fitness to drive before driving a vehicle

  • Long-term use of cannabis-based medicines in two children with Tourette syndrome

    Open Access•Lara-Katharina Woerner, Natalia Szejko et al.•ARTICLE•Frontiers in Psychiatry•2025

    We present two cases of minors with TS who started CBM treatment at the age of eight and 12 years, respectively, and continued treatment for five to six years resulting in clinically relevant symptom improvement without any severe adverse effects or negative impact on cognitive and academic performance

  • Dissemination and reception of a functional tourette-like behavior via YouTube

    Claudia Wegener, Kirsten Müller‐Vahl et al.•ARTICLE•Information Communication & Society•2023

    With the emergence of such videos addressing Tourette syndrome on YouTube, in which affected persons present themselves, Tourette experts observe an increasing number of patients showing Tourette-like symptoms. Interviews show that they are not only familiar with these videos but have also dealt with them in different ways. Medical analyses combined with the evaluations of the interviews give reason to believe that the videos can be interpreted a…

  • Mass social media-induced illness presenting with Tourette-like behavior

    Open Access•Carolin Fremer, Natalia Szejko et al.•ARTICLE•Frontiers in Psychiatry•2022

    Currently, we are facing a new manifestation of functional neurological disorder presenting with functional Tourette-like behavior (FTB). This study aimed to show characteristics of this phenotype presenting as an outbreak of "mass social media-induced illness" (MSMI) and to explore predisposing factors. Between 5-9/2021, we prospectively investigated 32 patients (mean/median age: 20.1/18 years, range: 11-53 years, n = 16 females) with MSMI-FTB u…

  • Yale Global Tic Severity Scale (YGTSS)

    Open Access•Martina Haas, Ewgeni Jakubovski et al.•ARTICLE•Frontiers in Psychiatry•2021

    The Yale Global Tic Severity Scale (YGTSS) is a clinician-rated instrument considered as the gold standard for assessing tics in patients with Tourette's Syndrome and other tic disorders. Previous psychometric investigations of the YGTSS exhibit different limitations such as small sample sizes and insufficient methods. To overcome these shortcomings, we used a subsample of the large-scale "European Multicentre Tics in Children Study" (EMTICS) inc…

  • Cannabis Improves Obsessive-Compulsive Disorder—Case Report and Review of the Literature

    Open Access•Natalia Szejko, Carolin Fremer et al.•ARTICLE•Frontiers in Psychiatry•2020

    Although several lines of evidence support the hypothesis of a dysregulation of serotoninergic neurotransmission in the pathophysiology of obsessive-compulsive disorder (OCD), there is also evidence for an involvement of other pathways such as the GABAergic, glutamatergic, and dopaminergic systems. Only recently, data obtained from a small number of animal studies alternatively suggested an involvement of the endocannabinoid system in the pathoph…

  • The Canna-Tics Study Protocol

    Open Access•Ewgeni Jakubovski, Anna Pisarenko et al.•ARTICLE•Frontiers in Psychiatry•2020

    Background: Gilles de la Tourette syndrome (TS) is a chronic neuropsychiatric disorder characterized by motor and vocal tics. First-line treatments for tics are antipsychotics and tic-specific behavioral therapies. However, due to a lack of trained therapists and adverse events of antipsychotic medication many patients seek alternative treatment options including cannabis. Based on the favorable results obtained from case studies on different can…
