Newest firstBackground: Tourette syndrome (TS) is a chronic neurodevelopmental disorder with a significant rate of patients remaining refractory to standard treatments. Refractory TS is defined as the persistence of clinically significant tics causing functional impairment despite adequate trials of both behavioral therapy and at least two generally accepted pharmacological treatments from different classes, administered at a…
Open article record in new tab ↗PURPOSE OF REVIEW: This review aims to collate takeaways from the most recent and relevant literature related to tics, from genetic studies to case studies elucidating Functional tic like behaviors (FTLBs) and clinical trials of novel drugs in development. RECENT FINDINGS: Recent genome-wide association studies (GWAS) and functional neuroimaging studies have enhanced the understanding of genetic and structural lin…
Open article record in new tab ↗Medicinal cannabis has been trialled for Tourette syndrome in adults, but it has not been studied in adolescents. This open-label, single-arm trial study evaluated the feasibility, acceptability and signal of efficacy of medicinal cannabis in adolescents (12-18 years), using a Δ9-tetrahydrocannabinol:cannabidiol ratio of 10:15, with dose varying from 5 to 20 mg/day based on body weight and response. The study demo…
Open article record in new tab ↗Tourette syndrome is characterized by at least two motor tics and one vocal tic, which persist for over a year. Infrequently, tics can manifest as blocking tics in speech when they prevent a person from starting to speak or interrupt their speech flow. Vocal blocking tics (VBTs) resemble stuttering, and they can be difficult to differentiate from each other. A previous report described two patients with severe VBT…
Open article record in new tab ↗Δ9-Tetrahydrocannabinol (Δ9-THC) inhibits tics in individuals with Tourette syndrome (TS). Δ9-THC has similar affinities for CB1/CB2 cannabinoid receptors. However, the effect of HU-308, a selective CB2 receptor agonist, on repetitive behaviors has not been investigated. The effects of 2,5-dimethoxy-4-iodoamphetamine (DOI)-induced motor-like tics and Δ9-THC were studied with gene analysis. The effects of HU-308 on…
Background Tourette syndrome (TS) manifests with motor and vocal tics that can reach disabling intensity. Established therapies may show insufficient relief or side effects. Cannabinoids have demonstrated therapeutic potential in small studies. This report presents buccal Nabiximols "as required" in the treatment of tics in TS. Case report A 25-year-old man presented with stigmatizing motor and phonic tics after c…
Open article record in new tab ↗In 2011, the European Society for the Study of Tourette Syndrome (ESSTS) published the first European guidelines for Tourette Syndrome (TS). We now present an update of the part on pharmacological treatment, based on a review of new literature with special attention to other evidence-based guidelines, meta-analyses, and randomized double-blinded studies. Moreover, our revision took into consideration results of a…
Open article record in new tab ↗Gilles de la Tourette syndrome (TS) is a complex neurodevelopmental disorder characterized by the presence of motor and vocal tics as well as psychiatric comorbidities such as attention-deficit/hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), depression, and anxiety. The underlying cause of the disease is still unknown, but several lines of evidence suggest a paramount role of the dopaminergic s…
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 f…
We report the cases of two young German male patients with treatment-resistant Tourette syndrome (TS), who suffer from incapacitating stuttering-like speech disfluencies caused by vocal blocking tics and palilalia. Case 1: a 19-year old patient received medical cannabis at a dose of 1 × 0.1 g cannabis daily. Case 2: a 16-year old patient initially received dronabinol at a maximum dose of 22.4-33.6 mg daily. Both t…
Open article record in new tab ↗The first World Congress on Tourette Syndrome and Tic Disorders was held in London, June 2016 by the Tourette Association of America, Tourettes Action (UK), and the European Society for the Study of Tourette Syndrome. Presentations arising from large-scale collaborative projects were an important component of the scientific programme. This article focuses on areas raised in the hot topics session and two moderated…
