Abstract
Tourette syndrome (TS) is a complex neurodevelopmental disorder characterized by the presence of tics, frequently accompanied by a variety of neuropsychiatric comorbidities. A subset of patients with TS present with severe and disabling symptoms, requiring prompt therapeutic intervention. Some of these manifestations may result in medical emergencies when severe motor or phonic tics lead to damage of anatomical structures closely related to the tic. Examples include myelopathy or radiculopathy following severe neck ("whiplash") jerks or a variety of self-inflicted injuries. In addition to self-aggression or, less commonly, allo-aggression, some patients exhibit highly inappropriate behavior, suicidal tendencies, and rage attacks which increase the burden of the disease and are important components of "malignant TS". This subset of TS is frequently associated with comorbid obsessive-compulsive disorder. Therapeutic measures include intensive behavioral therapy, optimization of oral pharmacotherapy, botulinum toxin injections, and deep brain stimulation.

Abstract
Tourette's syndrome (TS) patients experiencing severe tics and behavioral disturbances can have a rare complication called rhabdomyolysis (RML), which is characterized by the breakdown of muscle tissue. The occurrence of RML poses a significant physical and emotional risk to patients with TS by impacting the quality of life and in some cases causing severe damage. In this case report, we present the first documented case of RML resulting from severe tics in an adult with a diagnosis of TS. The patient exhibited severe tics and self-injurious behaviors that led to elevated creatine kinase and a subsequent diagnosis of RML requiring hospitalization with a complex hospital course. The patient did not have neuroleptic malignant syndrome as his laboratory parameters improved with the decrease in severity of tics. Our case highlights the potential complication of RML because of severe tics independent of neuroleptic drug use in a patient with TS.

Abstract
Self-injurious behaviors are repetitive, persistent actions directed toward one's body that threaten or cause physical harm. These behaviors are seen within a broad spectrum of neurodevelopmental and neuropsychiatric conditions, often associated with intellectual disability. Injuries can be severe and distressing to patients and caregivers. Furthermore, injuries can be life-threatening. Often, these behaviors are challenging to treat and require a tiered, multimodal approach which may include mechanical/physical restraints, behavioral therapy, pharmacotherapy, or in some cases, surgical management, such as tooth extraction or deep brain stimulation. Here, we describe a series of 17 children who presented to our institution with self-injurious behaviors in whom botulinum neurotoxin injections were found helpful in preventing or lessening self-injury.

Investigating Acupoint Selection and Combinations of Acupuncture for Tic Disorders: An Association Rule Mining and Network Analysis Study. Front Neurol 2022; 13:894951. [PMID: 35756940 PMCID: PMC9226724 DOI: 10.3389/fneur.2022.894951] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Accepted: 05/17/2022] [Indexed: 12/02/2022] Open
Abstract
Objective Tic disorders (TDs) are common mental disorders in children and adolescents, and the clinical application of acupuncture for treating TDs is becoming increasingly widespread. However, the criteria for selecting acupoint prescriptions and combinations have not been summarized. Therefore, data mining was used herein to determine the treatment principles and the most effective acupoint selection and compatibility criteria for the treatment of TDs. Methods Clinical studies and observations of the efficacy of acupuncture treatment for TDs were obtained from the PubMed, Cochrane Library, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang, VIP, and Chinese Biomedical (CBM) databases. The data on the acupoint prescriptions applied in these studies were collected, and network and association analyses were used to reveal the relationships between acupoints and to identify acupoint combinations. Additionally, the principles of acupuncture for TDs were determined through cluster analysis. Subgroup analysis of acupuncture prescriptions based on specific categorical diagnoses was performed to further assess the selection of acupoints. Results Eighty-six trials were identified, and 257 groups of effective prescriptions involving 121 acupoints were extracted. Bai-hui (DU20), Feng-chi (GB20), Tai-chong (LR3), He-gu (LI4), and San-yin-jiao (SP6) were the most regularly used acupoints for treating TDs. The Governor Vessel, gallbladder, and large intestine meridians were more commonly used than other meridians. Moreover, most acupoint sites focused on the head and neck. Network analysis revealed potentially effective acupoint prescriptions for their commonly used acupoints, namely, Bai-hui (DU20), Si-shen-cong (EX-HN1), Feng-chi (GB20), Nei-guan (PC6), Shen-men (HT7), He-gu (LI4), Zu-san-li (ST36), San-yin-jiao (SP6) and Tai-chong (LR3). Association rule mining indicated that potential point combinations that should be prioritized in TD treatment are Bai-hui (DU20), Neiguan (PC6) and Sanyinjiao (SP6). Cluster analysis revealed the treatment principle of “coordinating yin and yang, tonifying qi and blood, dispelling pathogenic wind and eliminating phlegm”. The core acupoint prescription of TS treatment comprised He-gu (LI4), Feng-chi (GB20), Tai-chong (LR3), Bai-hui (DU20), Yin-tang (EX-HN3), Si-shen-cong (EX-HN1), San-yin-jiao (SP6), and Nei-guan (PC6). The core group included He-gu (LI4) and Feng-chi (GB20). Proximal points were usually used in TS as an additional method of point selection. Conclusion Using data mining analysis of published studies, this study provides valuable information regarding the selection of the most effective acupoints and point combinations for clinical acupuncture practice for treating TDs.

A 2-year longitudinal follow-up of quantitative assessment neck tics in Tourette's syndrome. PLoS One 2021; 16:e0261560. [PMID: 34968403 PMCID: PMC8718009 DOI: 10.1371/journal.pone.0261560] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Accepted: 12/05/2021] [Indexed: 11/19/2022] Open
Abstract
Background Neck motor tics in Tourette’s syndrome can cause severe neck complications. Although addressed in a few longitudinal studies, the clinical course of Tourette’s syndrome has not been quantitatively assessed. We had previously developed a method for quantifying the angular movements of neck tics using a compact gyroscope. Here, we present a follow-up study aimed at elucidating the clinical course of neck tics at both the group and individual levels. Methods Eleven patients with Tourette’s syndrome from our previous study participated in the present study, and their neck tics were recorded during a 5-min observation period. The severity of neck symptoms was assessed using the Yale Global Tic Severity Scale. The peak angular velocities and accelerations, tic counts, and severity scores in our previous study (baseline) and the present study (2-year follow-up) were compared at the group and individual levels. The individual level consistency between baseline and follow-up were calculated using intra-class correlation coefficients (ICCs, one-way random, single measure). Results At the group level, no significant change was observed between baseline and follow-up. At the individual level, angular velocity (ICC 0.73) and YGTSS scores (ICC 0.75) had substantial consistency over the two time points, and angular acceleration (ICC 0.59) and tic counts (ICC 0.69) had moderate consistency. Conclusions The intensity and frequency of neck tics did not change over time. Therefore, quantification of angular neck motor tics will aid in identifying patients with neck tics at high risk for severe neck complications.

Abstract
Importance Severe forms of Tourette syndrome or chronic tic disorder (TS/CTD) may involve repeated head jerking. Isolated case reports have described a spectrum of severe neck disorders in individuals with TS/CTD. However, the nature and prevalence of cervical spine disorders in TS/CTD are unknown. Objective To establish if TS/CTD are associated with an increased risk of cervical spine disorders and related neurological complications compared with individuals from the general population. Design, Setting, and Participants All individuals born from 1973 to 2013 and living in Sweden between 1997 and 2013 were identified. Individuals with a record of TS/CTD diagnosed in specialist settings were matched on age, sex, and county of birth with 10 unexposed individuals randomly selected from the general population. Cox proportional hazards regression models were used to estimate the risk of vascular and nonvascular cervical spine disorders among exposed individuals, compared with unexposed individuals. Models were adjusted for other known causes of cervical spine injury. Data were analyzed from March 19 to May 16, 2021. Exposures International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnoses of TS/CTD in the Swedish National Patient Register. Main Outcomes and Measures Records of cervical vascular disorders (ie, aneurysm, cerebral infarction, transitory cerebral ischemia) and cervical nonvascular disorders (ie, spondylosis, cervical disc disorders, fractures of the cervical spine, cervicalgia) and cervical surgeries. Covariates included rheumatic disorders, traffic injuries, fall- or sport-related injuries, and attention-deficit/hyperactivity disorder comorbidity. Results A total of 6791 individuals with TS/CTD were identified (5238 [77.1%] were male; median [interquartile] age at first diagnosis, 15.6 [11.4-23.7] years) and matched to 67 910 unexposed individuals. Exposed individuals had a 39% increased risk of any cervical spine disorder (adjusted hazard ratio, 1.39; 95% CI, 1.22-1.59). Adjusted hazard ratios for cervical vascular and nonvascular disorders were 1.57 (95% CI, 1.16-2.13) and 1.38 (95% CI, 1.19-1.60), respectively. Risks were similar among men and women. Conclusions and Relevance Individuals with severe TS/CTD are at increased risk of cervical spine disorders. These outcomes are relatively rare but may lead to persistent disability in some individuals and thus require close monitoring to facilitate early interventions.

Abstract
INTRODUCTION Tourette syndrome (TS) is characterized by the presence of motor and phonic tics, as well as a variety of behavioral co-morbidities. Self-injurious behavior (SIB) is one of the most serious manifestations of TS, but its pathophysiology is poorly understood. METHODS Consecutive patients with TS studied in a tertiary care center. RESULTS We identified a total of 34 patients (16.9%) with SIB from a cohort of 201 patients with TS. Most of these patients (n = 23, 11.4%) experienced self-directed damage; while others had outward-directed (n = 7, 3.5%) or tic-related SIB (n = 4, 2%). Compared to other patients with TS, those who manifested SIB (self- and outward-directed damage) were more likely to have tics involving shoulder (P = 0.046), trunk (P = 0.006), and arm (P = 0.017); as well as dystonic tics (P = 0.016); complex motor tics (P < 0.001), copropraxia (P = 0.045), complex phonic tics (P = 0.003), higher number of phonic tics (P = 0.001), verbalizations (P = 0.001), coprolalia (P = 0.006) and obsessive compulsive disorder (OCD) (P < 0.001) as determined by bivariate analysis. In the multivariate analysis only complex motor tics (P = 0.006), obsessive-compulsive behavior (P = 0.025) and greater severity of tics (P = 0.002) showed a statistically significant association with SIB. Patients with SIB had a greater probability of being selected for deep brain stimulation (DBS) therapy by the treating clinician (P = 0.01). CONCLUSIONS SIB is observed in about 17% of patients with TS. The presence of complex motor tics, OCD and greater severity of tics was related to the presence of SIB.

Eur J Neurol 2021; 28:3187-3200.

Abstract
BACKGROUND AND PURPOSE The neurobiology of Gilles de la Tourette syndrome (GTS) is known to involve corticostriatal loops possibly under genetic control. Less is known about possible environmental triggers of GTS. Specifically, immune-related events following possible environmental inducers have been evoked, but important controversies still exist. In this systematic review and meta-analysis, we looked for evidence in favor of such possibilities. METHODS We performed a systematic review and meta-analysis of all immunological data in PubMed. RESULTS We found large discrepancies concerning immune dysfunctions in GTS, and meta-analyzing cytokines data did not allow us to conclude there is an involvement of specific cytokines in GTS neurobiology. When looking specifically at pediatric autoimmune neuropsychiatric disorder associated with streptococcus/pediatric acute onset neuropsychiatric syndrome, we found some important evidence of a possible infectious involvement but in a limited number of studies. Our meta-analysis found an increased level of anti-streptolysin O antibodies in GTS patients, but the level of anti-DNase B antibodies was not increased. CONCLUSIONS Too many questions still exist to allow us to definitively reach the conclusion that there is an infectious and immunological etiology in GTS. Much work is still needed to elucidate the possible role of immunology in GTS neurobiology and to favor immunological treatment rather than classical treatment.

Abstract
Tourette syndrome (TS) is a condition wherein motor and vocal tics occur, provoked by an urge, but often not able to be completely voluntarily controlled. Tics are known to cause physical and emotional risks to quality of life, and in rare extreme cases, may have permanent consequences. We report the first cases, to our knowledge, of rhabdomyolysis due to extreme tic fits in two distinct patients with TS. Both patients presented with severe tics, leading to elevated creatine kinase and a diagnosis of rhabdomyolysis requiring hospitalisation and intravenous fluids. Neither had neuroleptic malignant syndrome. One patient was on concurrent neuroleptic therapy, but his laboratory parameters improved when tics subsided despite continued neuroleptic use. Our cases highlight the potential complication of rhabdomyolysis secondary to severe tic fits independent of neuroleptic use.

Abstract
Movement disorders presenting in childhood include tics, dystonia, chorea, tremor, stereotypy, myoclonus, and parkinsonism, each of which can be part of various clinical syndromes with distinct etiologies. Some of these conditions are benign and require only reassurance; others are bothersome and require treatment, or may be clues that herald underlying pathology. Answers lie in the inherent characteristics of the movements themselves, together with the clinical context provided in the history obtained by the examiner. The aim of this review is to present an overview of the categories of involuntary movements, along with examples of common acquired and genetic causes, and an approach to history-taking, examination, and treatment.

Abstract
Cervical myelopathy can occur in Tourette syndrome patients with severe motor tics showing repetitive and violent neck movements. However, motor tics causing spinal fractures have been rarely reported. A 15-year-old girl presented at our clinic, complaining of recent development of motor weakness of all 4 extremities. She had untreated motor tics involving the neck. Computed tomography and magnetic resonance imaging findings suggested cervical spinal fractures and myelopathy. After diagnosing of Tourette syndrome, medical and psychologic therapies were started. Her motor tics were well controlled, and no complications in the patient's daily life were observed later. Cervical radiography taken at a 9-month follow-up showed bony healings of the fractured cervical spines. Uncontrolled severe motor tics may cause spinal fractures. Conservative treatments would suffice for proper control of these tics and stabilize the spine, and considered as initial treatment in patients with Tourette syndrome.

Abstract
Tourette syndrome is a complex neuropsychiatric disorder with a wide phenotypic spectrum, including tics and psychiatric comorbidities, such as obsessive-compulsive disorder and attention-deficit disorder. Often considered a neurodevelopmental disorder, it is most prevalent during childhood and treatment strategies can vary according to degree of severity and patient-specific symptom manifestations. This review focuses on established and emerging management options for tics, including behavioral interventions and nonpharmacologic therapies, medication management, and promising surgical approaches.

Abstract
Tics are the most common movement disorder in childhood and are a frequent reason for referral to child neurology clinics. The purpose of this review is to examine the phenomenology of tics, discuss what is known regarding their genetic and pathophysiological causes and to evaluate current treatment options. The evidence for the evaluation and treatment of the controversial diagnosis of pediatric autoimmune neuropsychiatric disorders associated with group A streptococci (PANDAS) will also be reviewed. With improved understanding of tic disorders, their etiology and response to current treatment options, we may be able to more effectively diagnose them and identify novel treatment strategies.

Abstract
Tourette syndrome is a neuropsychiatric condition characterized by both motor and phonic tics over a period of at least 1 year with the onset in childhood or adolescence. Apart from the tics, most of the patients with Tourette syndrome have associated neuropsychiatric comorbidities consisting of attention deficit hyperactivity disorder, obsessive compulsive disorder, rage attacks, sleep issues, depression, and migraine. Patients may also have physical complications directly from violent motor tics which can rarely include cervical myelopathy, arterial dissection, and stroke. The purpose of this article is to review the associated neuropsychiatric comorbidities of Tourette syndrome with emphasis on recent research.
