Tic Disorders

Resources for Patients and Caregivers

Tics are sudden twitches, movements, or sounds that people do repeatedly. People who have tics cannot stop their body from doing these things. For example, a person with a motor tic might keep blinking over and over again. Or, a person with a vocal tic might make a grunting sound unwillingly.

  • Functional tic-like behaviours during the COVID-19 pandemic: Follow-up over 12 months
    by Adriana Prato on January 26, 2023

    CONCLUSION: Our data suggest that several characteristics in clinical course and their phenomenology can help clinicians to distinguish functional tic-like behaviours from organic tics. Our results also suggest a better outcome for tics and anxiety symptoms respect on other comorbidities. A prompt diagnosis and management not only of tics but also comorbidities are recommended, as generally conventional pharmacotherapy for tics does not have positive effects on these patients.

  • Estradiol provokes hypercoagulability and affects fibrin biology: A mechanistic exploration of sex dimorphisms in coagulation
    by Julia R Coleman on January 25, 2023

    CONCLUSION: Estradiol provokes a hypercoagulable phenotype, affecting time to clot formation, clot propagation, clot strength, clot fibrinolysis, and clot structure. In sum, these data highlight the role of estradiol is driving female-specific hypercoagulability and highlights its potential role as a therapeutic adjunct in resuscitation of TIC.

  • Impact of Tourette's syndrome tics on healing following dental trauma
    by Rakhee Budhdeo on January 25, 2023

    The following case report outlines the impact of motor tics linked to Tourette's syndrome on dental development and healing following a dental injury to a maxillary central incisor. Emergency care and splinting of a mobile extruded maxillary left central incisor tooth was carried out at the local dentist on the same day as the dental trauma. A subsequent referral was made to the paediatric dental department for continued mobility of the maxillary central incisor on splint removal approximately 2...

  • Molecular Landscape of Tourette's Disorder
    by Joanna Widomska on January 21, 2023

    Tourette's disorder (TD) is a highly heritable childhood-onset neurodevelopmental disorder and is caused by a complex interplay of multiple genetic and environmental factors. Yet, the molecular mechanisms underlying the disorder remain largely elusive. In this study, we used the available omics data to compile a list of TD candidate genes, and we subsequently conducted tissue/cell type specificity and functional enrichment analyses of this list. Using genomic data, we also investigated genetic...
