The chill of the winter season has just begun and we’re already thinking about warmer times ahead. Every June the Tourette Association of America funds various Doctors and Researchers that explore new, promising treatment options for Tourette Syndrome and Tic Disorders. This may feel far away, but the process begins now for this upcoming June. Through a rigorous application process, the TAA is proud to hand select these brilliant individuals to help see our mission in action. Click here to read about the nine funded grants for 2016!
With your continued support, the TAA is poised to facilitate clinical studies that improve the accuracy and timeliness of obtaining a TS diagnosis; foster development of surgical approaches (e.g. Deep Brain Stimulation) to treating severe TS; and support studies to investigate more closely the genetic and environmental causes of and determine the specific brain areas and nerve cells that are affected in Tourette.
We believe the future holds even more promise; but we can’t do it alone. Please help the Tourette Association of America keep innovation alive for the Tourette community. Click here to donate to the TAA’s Research and Medical Programs today!
Cannabidiol for the Treatment of Tourette Syndrome in Adults
Meagan O’Brien Bailey, M.D. | Rush University Medical Center, Chicago, IL | $39,056
There have been reports that marijuana can be effective in decreasing the amount of tics in Tourette Syndrome (TS). Marijuana would be difficult for most people to use on a daily basis because its main active compound, THC, causes the high associated with the drug and affects the ability to work or go to school. Another common compound found in marijuana called cannabidiol has been isolated, and because it does not cause the high associated with THC it is more easily tolerated and can be taken daily. We plan on studying this drug and whether or not it can decrease tic frequency in adults with TS.
Pilot Study to Evaluate Feasibility of a Novel Voluntary Movement Suppression Paradigm using Real-Time Motor Physiological Feedback in Children with TS
Donald L. Gilbert, M.D., M.S. | Cincinnati Children’s Hospital Medical Center, Cincinnati, OH | $63,275
In children with Tourette Syndrome (TS), tics, impulsive actions, and compulsions may result partly from difficulties in the brain’s systems for “stopping.” We propose to learn more about and improve this stopping by using transcranial magnetic stimulation and electrical measurements in muscles to compare the brain’s stopping system in children with and without TS. We will then use a new training method called “Selective Suppression with Real-Time Feedback” to evaluate how well children can learn to activate their stopping system. Ultimately we aim to find out whether this method can help children gain better control over their unwanted actions.
Investigating the Feasibility, Acceptability and Initial Efficacy of a Comprehensive Transdiagnostic Treatment for Complex Comorbidity in Tourette Disorder
Michael B. Himle, Ph.D. and Adam Lewin, Ph.D.| University of Utah, Salt Lake City, UT and University of South Florida, Tampa, FL | $136,500
Children with Tourette Disorder often have additional emotional and behavioral problems which may cause more problems than their tics. Currently, psychological treatments generally take on one disorder at a time that can be time consuming, impractical and expensive. The goal of this project is to develop and test a psychological treatment for children and adolescents to manage the many symptoms that may accompany tics – including problems controlling emotions, acting out, reacting without thinking, and trouble making good
Endogenous and Behavioral Markers of Circadian Rhythmicity in Adults with Persistent Tic Disorders: A Pilot Investigation
Emily J. Ricketts, Ph.D. | University of California, Los Angeles, Los Angeles, CA | $130,415
Individuals with Persistent Tic Disorders (PTDs) often experience sleep problems, including difficulties falling asleep and staying asleep. Sleep is regulated partly by the circadian system, a near-24-hour biological clock. Prior research suggests the presence of circadian disruption (body temperature, and cortisol dysregulation) in PTDs. Such disruption may impact tic severity and quality of life. Therefore, this study will evaluate circadian rhythms in 20 adults with PTDs and 20 healthy control participants through assessment of endogenous melatonin, circadian phase preference, and 24-hour rest/activity rhythms. Findings may aid our understanding of the nature of tic symptom variability, and help enhance existing treatments.
Frontline Home-based CBIT Treatment Program
Harvey S. Singer, M.D. | Johns Hopkins Hospital, Baltimore, MD | $136,500
Comprehensive Behavioral Intervention for Tics (CBIT) is a safe, effective treatment for Tourette Syndrome (TS). Unfortunately, there remain insufficient numbers of trained behaviorists to meet the needs of most TS patients. In this study, we will develop a home-based behavioral treatment instructional video and guide. We will then compare reductions in tic severity using this parent-administered therapy to that achieved with traditional face-to-face treatment by an experienced psychologist. Evidence of effectiveness of home-based, parent-directed therapy would enable direct frontline treatment for all individuals affected with tics
Modeling a Tourette-related Human Development Disorder in Mice with Nerve Growth Factor-related Gene Mutations
Kenneth E. McCarson, Ph.D. | University of Kansas Medical Center; Kansas City, KS | $136,500
Advances in reading people’s genetic code have helped in understanding rare genetic disorders. Our gene sequencing program identified rare gene sequence variations in members of a family with TS across multiple generations. We used this genetic
information to engineer mice with identical changes in their normal gene sequence, and will be testing those mice to observe behavioral and anatomic brain changes that might mimic those in the TS affected family. These mice will establish an animal model of TS that could be instrumental in understanding the causes of TS and developing strategies for treating TS.
Basal Ganglia Circuit Mechanisms of Orofacial and Vocal Actions
Lauren E. McElvain, Ph.D. | University of California, San Diego, San Diego, CA | $40,000
Tourette Syndrome is thought to arise from dysfunction of neural circuits in the basal ganglia, a set of nuclei that control the selection of motor actions. Although prominent symptoms of Tourette Syndrome include aberrant orofacial and vocal actions,
how the basal ganglia normally control these actions remains poorly understood. Therefore, we are mapping the basal ganglia circuit pathways that control orofacial and vocal musculature and determining how neurons in these pathways appropriately activate target muscles. Our findings will enable more specific circuit studies of Tourette symptoms with the ultimate goal of identifying more specific therapeutics for orofacial and vocal symptoms.
Incorporating TeleCBIT into a Hospital-based Tic Clinic
Matthew Capriotti, Ph.D. | San Jose State University, San Jose, CA. | $130,000
We know that several medications can effectively reduce TS symptoms. We also know that a behavioral treatment called
Comprehensive Behavioral Intervention for Tics, or CBIT, can work very well; whether it’s delivered face-to-face or remotely via video conferencing technology. Most of what we know about these treatments comes from tightly-controlled studies, which are
scientifically very sound, but may not reflect how things work in typical clinic settings. So, in this study, we will be comparing these different treatments in a hospital tic clinic under “real-world” conditions. We hope to learn what treatments patients prefer to try, both as first- and second-line treatments. We also hope to begin to learn about how well these treatments work compared to one another in this clinic setting.
Integrating TS Genetics into the Psychiatric Genetics Consortium
Jeremiah Scharf, M.D., Ph.D. and Carol Mathews, M.D.| Massachusetts General Hospital, Boston, MA and University of Florida, Gainesville, FL | $90,000
Through collaboration with TS genetics investigators throughout the world, the TAA International Consortium for Genomics (TAAICG)
seeks to advance the knowledge of genetic susceptibilities that underlie Tourette Syndrome and related disorders.
