Hatfield T, Johnson S. Knockdown of the GABARAP ortholog Atg8a elicits deficits in learning and promotes obsessive behaviors in Drosophila melanogaster. MICROPUBLICATION BIOLOGY 2024; 2024.

Abstract
In humans, trafficking of the GABA(A) receptor by GABARAP can lead to obsessive behaviors and learning deficits often in seen in neurological disorders such as Tourette's Syndrome. We find that in Drosophila melanogaster , Atg8a , the ortholog of the human GABARAP gene, is necessary in the nervous system for learning and suppression of excessive grooming. These results suggest that knocking down Atg8a in neurons of Drosophila produces a phenotype similar to that seen in human patients, potentially allowing for use of an Atg8a knockdown background as a suitable invertebrate model for related neurological conditions.

Impacts of ADHD Symptomatology on the Response to Cognitive-Behavioural Therapy with Gilles de la Tourette Syndrome Patients. J Clin Med 2024; 13:2975. [PMID: 38792517 PMCID: PMC11122476 DOI: 10.3390/jcm13102975] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Revised: 05/10/2024] [Accepted: 05/16/2024] [Indexed: 05/26/2024] Open
Abstract
(1) Background: Gilles de la Tourette Syndrome (TS) is a neurodevelopmental disorder characterized by motor and vocal tics. Attention deficit and hyperactivity disorder (ADHD) is a common comorbidity of TS that adds further impairment. Cognitive-behavioural therapy (CBT) has shown efficacy in treating tics, yet its effectiveness in individuals with TS and comorbid ADHD remains unclear. Also, it is suggested that ADHD characteristics like executive dysfunction and inattention could hinder the response to CBT. This study aims to compare the response to CBT for tics and its maintenance six months post-therapy among TS individuals with and without ADHD symptoms. (2) Methods: In this study, 55 TS participants who completed 14-week CBT for tics were split into high (TS+) or low (TS-) ADHD symptomatology groups. Outcomes were evaluated using the Yale Global Tic Severity Scale (YGTSS) regarding global tic severity and motor and vocal tic frequency post-CBT and at a 6-month follow-up. (3) Results: No significant group difference was found regarding improvements post-CBT (n = 55), nor the maintenance six months later (n = 45). (4) Conclusions: ADHD symptoms may not hinder the response to CBT or its maintenance, suggesting that TS individuals with ADHD symptoms may not require specialized CBT interventions.

Abstract
BACKGROUND Transcranial magnetic stimulation (TMS) is a noninvasive brain stimulation technique that may potentially be helpful for neuropsychiatric symptoms of developmental disorders with inflammatory aspects. TMS utilizes a varying magnetic field to induce electrical changes in the brain. Repetitive use of TMS modulates plasticity at multiple levels, particularly at the synapse and network level. SUMMARY As inflammation can affect synaptic plasticity negatively, TMS may theoretically be a tool to address this inflammation-induced dysfunction. There are also data to suggest that TMS can directly downregulate inflammation. Neuropsychiatric consequences of multiple disorders with inflammatory aspects, particularly neurodevelopmental disorders like autism, Tourette syndrome, and obsessive-compulsive disorder (OCD), maybe treated effectively with TMS. Treatment of OCD, treatment-resistant major depression, and nicotine cessation (all in adults) are currently FDA-cleared indications, while migraine is cleared for ages 12 and above. KEY MESSAGES TMS will likely continue to grow in terms of indications as research continues to assess what brain networks are dysfunctional in various disorders and it becomes clearer how to modulate these networks. TMS may thus be best understood as a technology platform that can be utilized to modulate different brain networks affected in neuropsychiatric disorders. TMS is likely to become an increasingly important tool in targeting brain networks that could become dysfunctional in part due to inflammation in the developing brain and addressing consequent neuropsychiatric symptoms.

Effects of Yi-Gan-san on the psychiatric behavior of children and adolescents with Tourette's Syndrome: A randomized, double-blind, controlled preliminary study. JOURNAL OF ETHNOPHARMACOLOGY 2022; 290:115098. [PMID: 35182665 DOI: 10.1016/j.jep.2022.115098] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 01/25/2022] [Accepted: 02/07/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gilles de la Tourette's Syndrome (TS) is a childhood-onset disease with clinical features of motor and phonic tics. Yi-Gan-san (YGS) is a traditional Chinese medicine formula that can reduce aggressiveness and agitation and inhibit dopamine function. This study investigated the effects of YGS on the psychiatric behavior of children and adolescents with TS. METHODS A double-blind, randomized, controlled preliminary study was conducted. A total of 38 patients with TS were assigned to the control group (CG, 19 patients) who received the oral administration of YGS placebo (90% starch and 10% YGS; 2.5 g thrice daily) or to a treatment group (TG, 19 patients) who received YGS for 4 weeks. The primary outcome measure was the change in Yale Global Tic Severity Scale (YGTSS) overall and subscale scores. RESULTS The intensity score for phonic tics before oral administration of YGS, and after 2 weeks, 3 weeks and 4 weeks was not significantly different between CG and TG groups (2.94 ± 1.14 vs 2.79 ± 1.08, p = .686; 2.29 ± 1.21 vs 1.95 ± 1.08, p = .370; 2.41 ± 1.18 vs 2.05 ± 1.51, p = .435; and 2.29 ± 1.26 vs 1.84 ± 1.42, p = .323, respectively), while the intensity score for phonic tics after 1-week oral administration of YGS in the TG was 1.89 ± 1.10 lower than 3.06 ± 1.39 in the CG (p = .008). CONCLUSION Oral administration of YGS for 1 week only reduced the intensity of phonic tics compared with oral administration of YGS placebo, suggesting that YGS can reduce their intensity for a short period, and the compliance of oral administration of YGS for 4 weeks can be accepted in children and adolescents with Tourette's Syndrome. However, because this study was preliminary, the selection of an appropriate placebo and dosage and long-term observations are crucial areas for future studies.

Transcriptome-wide association study reveals increased neuronal FLT3 expression is associated with Tourette's syndrome. Commun Biol 2022; 5:289.

Abstract
Tourette's Syndrome (TS) is a neurodevelopmental disorder that is characterized by motor and phonic tics. A recent TS genome-wide association study (GWAS) identified a genome-wide significant locus. However, determining the biological mechanism of GWAS signals remains difficult. To characterize effects of expression quantitative trait loci (eQTLs) in TS and understand biological underpinnings of the disease. Here, we conduct a TS transcriptome-wide association study (TWAS) consisting of 4819 cases and 9488 controls. We demonstrate that increased expression of FLT3 in the dorsolateral prefrontal cortex (DLPFC) is associated with TS. We further show that there is global dysregulation of FLT3 across several brain regions and probabilistic causal fine-mapping of the TWAS signal prioritizes FLT3 with a posterior inclusion probability of 0.849. After, we proxy the expression with 100 lymphoblastoid cell lines, and demonstrate that TS cells has a 1.72 increased fold change compared to controls. A phenome-wide association study also points toward FLT3 having links with immune-related pathways such as monocyte count. We further identify several splicing events in MPHOSPH9, CSGALNACT2 and FIP1L1 associated with TS, which are also implicated in immune function. This analysis of expression and splicing begins to explore the biology of TS GWAS signals.

Abstract
Many behavioral and psychological symptoms of dementia (BPSD) share similarities in executive functioning and communication deficits with those described in several neuropsychiatric disorders, including Alzheimer's disease (AD), epilepsy, schizophrenia (SCH), and autism spectrum disorder (ASD). Numerous studies over the last four decades have documented altered neuroinflammation among individuals diagnosed with ASD. The purpose of this review is to examine the hypothesis that central histamine (HA) plays a significant role in the regulation of neuroinflammatory processes of microglia functions in numerous neuropsychiatric diseases, i.e., ASD, AD, SCH, and BPSD. In addition, this review summarizes the latest preclinical and clinical results that support the relevance of histamine H1-, H2-, and H3-receptor antagonists for the potential clinical use in ASD, SCH, AD, epilepsy, and BPSD, based on the substantial symptomatic overlap between these disorders with regards to cognitive dysfunction. The review focuses on the histaminergic neurotransmission as relevant in these brain disorders, as well as the effects of a variety of H3R antagonists in animal models and in clinical studies.

Abstract
Research has demonstrated children who stutter score significantly lower than children who do not stutter on the Purdue Pegboard Test. Past data also suggest performance on this task may be associated with stuttering frequency (Choo et al., 2016; Mohammadi et al., 2016). The purpose of this study was to explore whether these performance differences and the relationship to stuttering frequency are present in adults who stutter (AWS). Forty-eight participants (AWS = 24, and AWNS = 24) matched for age, gender, education, and handedness completed all four tasks of the Purdue Pegboard Test. There were no significant between group differences and stuttering frequency did not predict performance. These findings suggest previous differences may only be applicable to subgroups and/or that, with development, the manual tasks unique to the Purdue Pegboard Test may not be sensitive enough to reveal differences.

Abstract
Deep brain stimulation (DBS) is routinely used for treatment of movement disorders and it is also under investigation for neuropsychiatric disorders with deficient sensorimotor gating, such as schizophrenia, Tourette's syndrome and obsessive compulsive disorder. Electrical stimulation induces excitation and inhibition both at the stimulation site and at projection sites, thus modulating synchrony and oscillatory behavior of neuronal networks. We first provide background information on DBS in neuropsychiatric disorders accompanied by deficient sensorimotor gating. We then introduce prepulse inhibition (PPI) as a measure for sensorimotor gating in these disorders. Thereafter, we report on the use of DBS in rat models with deficient PPI induced by pharmacologic, genetic and neurodevelopmental manipulation. These models offer the opportunity to define the neuronal circuit regulation that is of relevance to PPI and its deficits in neuropsychiatric disorders with disturbed sensorimotor gating. Finally, we report on the use of the PPI paradigm in human patients operated for DBS on/off stimulation, which may further elucidate the neuronal network involved in regulation of PPI.

Abstract
BACKGROUND Huntington's disease (HD) is an autosomal dominant disorder, typically characterized by chorea due to a trinucleotide repeat expansion in the HTT gene, although the clinical manifestations of patients with juvenile HD (JHD) are atypical. CASE PRESENTATION A 17-year-old boy with initial presentation of tics attended our clinic and his DNA analysis demonstrated mutation in the HTT gene (49 CAG repeats). After treatment, his symptoms improved. Furthermore, we performed literature review through searching the databases and summarized clinical features in 33 JHD patients. CONCLUSION The most prevalent symptoms are ataxia, and two cases reported that tics as initial and prominent manifestation in JHD. Among them, 88% patients carried CAG repeats beyond 60 and most of them have family history. This case here illustrates the variable range of clinical symptoms of JHD and the necessity of testing for the HD mutation in young patients with tics with symptoms unable to be explained by Tourette's syndrome (TS).

Abstract
The histaminergic system (HS) has a critical role in cognition, sleep and other behaviors. Although not well studied in autism spectrum disorder (ASD), the HS is implicated in many neurological disorders, some of which share comorbidity with ASD, including Tourette syndrome (TS). Preliminary studies suggest that antagonism of histamine receptors 1-3 reduces symptoms and specific behaviors in ASD patients and relevant animal models. In addition, the HS mediates neuroinflammation, which may be heightened in ASD. Together, this suggests that the HS may also be altered in ASD. Using RNA sequencing (RNA-seq), we investigated genome-wide expression, as well as a focused gene set analysis of key HS genes (HDC, HNMT, HRH1, HRH2, HRH3 and HRH4) in postmortem dorsolateral prefrontal cortex (DLPFC) initially in 13 subjects with ASD and 39 matched controls. At the genome level, eight transcripts were differentially expressed (false discovery rate <0.05), six of which were small nucleolar RNAs (snoRNAs). There was no significant diagnosis effect on any of the individual HS genes but expression of the gene set of HNMT, HRH1, HRH2 and HRH3 was significantly altered. Curated HS gene sets were also significantly differentially expressed. Differential expression analysis of these gene sets in an independent RNA-seq ASD data set from DLPFC of 47 additional subjects confirmed these findings. Understanding the physiological relevance of an altered HS may suggest new therapeutic options for the treatment of ASD.

Abstract
OBJECTIVES Infections resulting in immune activation have been proposed to play an etiological role in a subgroup of patients with Tourette syndrome (TS). METHODS In order to further characterize the interaction between pathogens and the innate immune system the toll-like receptor (TLR) 4 on CD14 + monocytes and soluble CD14 (sCD14) levels were analyzed in the serum of 33 Tourette patients and 31 healthy controls. Moreover, collected blood samples were stimulated with lipopolysaccharide (LPS) mimicking a bacterial infection. TLR4 was analysed by flow cytometry, sCD14 was analysed by enzyme-linked immunosorbent assay. RESULTS Patients had a lower receptor expression of TLR4 after stimulation with LPS (P = 0.045) and higher levels of sCD14 (unstimulated P = 0.014, after LPS P = 0.045). The increase in TLR4 expression after stimulation with LPS was significantly higher in the control group (P = 0.041). CONCLUSIONS Higher levels of sCD14, lower levels of TLR4 expression after stimulation and a diminished up-regulation of TLR4 expression after LPS stimulation in patients might represent an impaired activation of the innate immune response in TS, especially in regard to bacterial infection. The impaired response to pathogens could eventually lead to a higher susceptibility for infections. Recurring infections and a chronic inflammation could trigger and maintain the symptoms of TS.

Abstract
To identify the association of Catechol-O-methyl transferase (COMT) -287A/G polymorphism with susceptibility to TS in Chinese Han population. We evaluated the genetic contribution of the COMT -287A/G polymorphism in 108 TS patients including all their parents in Chinese Han population using transmission disequilibrium test and haplotype relative risk design. Our results revealed that no significant association was found in COMT -287A/G genotypic and allelic frequencies with TS. Our results also suggested that there may be a lack of association between the TS and -287A/G polymorphism of COMT in Chinese Han population.

Abstract
BACKGROUND Tourette Syndrome (TS) has been linked to both genetic and environmental factors. Gene-expression studies provide valuable insight into the causes of TS; however, many studies of gene expression in TS do not account for the effects of medication. MATERIALS & METHODS To investigate the effects of medication on gene expression in TS patients, RNA was isolated from the peripheral blood of 20 medicated TS subjects (MED) and 23 unmedicated TS subjects (UNMED), and quantified using whole-genome Affymetrix microarrays. RESULTS D2 dopamine receptor expression correlated positively with tic severity in MED but not UNMED. GABA(A) receptor ε subunit expression negatively correlated with tic severity in UNMED but not MED. Phenylethanolamine N-methyltransferase expression positively correlated with tic severity in UNMED but not MED. CONCLUSION Modulation of tics by TS medication is associated with changes in dopamine, norepinephrine and GABA pathways.

Abstract
Tourette syndrome (TS) is a complex childhood neurodevelopmental disorder characterized by motor and vocal tics. Recently, altered numbers of GABAergic-parvalbumin (PV) and cholinergic interneurons were observed in the basal ganglia of individuals with TS. Thus, we postulated that gamma-amino butyric acid (GABA)- and acetylcholine (ACh)-related genes might be associated with the pathophysiology of TS. Total RNA isolated from whole blood of 26 un-medicated TS subjects and 23 healthy controls (HC) was processed on Affymetrix Human Exon 1.0 ST arrays. Data were analyzed to identify genes whose expression correlated with tic severity in TS, and to identify genes differentially spliced in TS compared to HC subjects. Many genes (3627) correlated with tic severity in TS (p < 0.05) among which GABA- (p = 2.1 × 10⁻³) and ACh- (p = 4.25 × 10⁻⁸) related genes were significantly over-represented. Moreover, several GABA and ACh-related genes were predicted to be alternatively spliced in TS compared to HC including GABA receptors GABRA4 and GABRG1, the nicotinic ACh receptor CHRNA4 and cholinergic differentiation factor (CDF). This pilot study suggests that at least some of these GABA- and ACh-related genes observed in blood that correlate with tics or are alternatively spliced are involved in the pathophysiology of TS and tics.

Abstract
Tourette Syndrome (TS) is diagnosed based upon clinical criteria including motor and vocal tics. We hypothesized that differences in exon expression and splicing might be useful for pathophysiology and diagnosis. To demonstrate exon expression and alternatively spliced gene differences in blood of individuals with TS compared to healthy controls (HC), RNA was isolated from the blood of 26 un-medicated TS subjects and 23 HC. Each sample was run on Affymetrix Human Exon 1.0 ST (HuExon) arrays and on 3' biased U133 Plus 2.0 (HuU133) arrays. To investigate the differentially expressed exons and transcripts, analyses of covariance (ANCOVA) were performed, controlling for age, gender, and batch. Differential alternative splicing patterns between TS and HC were identified using analyses of variance (ANOVA) models in Partek. Three hundred and seventy-six exon probe sets were differentially expressed between TS and HC (raw P < 0.005, fold change >|1.2|) that separated TS and HC subjects using hierarchical clustering and Principal Components Analysis. The probe sets predicted TS compared to HC with a >90% sensitivity and specificity using a 10-fold cross-validation. Ninety genes (transcripts) had differential expression of a single exon (raw P < 0.005) and were predicted to be alternatively spliced (raw P < 0.05) in TS compared to HC. These preliminary findings might provide insight into the pathophysiology of TS and potentially provide prognostic and diagnostic biomarkers. However, the findings are tempered by the small sample size and multiple comparisons and require confirmation using PCR or deep RNA sequencing and a much larger patient population.

Abstract
Gene expression microarrays are a high-throughput, cost-effective method for measuring the expression of all genes in a sample. By comparing the expression patterns of healthy controls to diseased subjects, the genetic regulatory pathways underlying and affected by the disease can be elucidated. Furthermore, dysregulated genes are possible candidates for pharmaceutical therapy. Here, we consider the possibility of applying this approach to Tourette syndrome. We also review current theories of Tourette syndrome etiology and pharmacology.

Abstract
To investigate the health-related quality of life (HrQoL) of adult patients with Gilles de la Tourette's syndrome (GTS) in Germany. HrQoL was evaluated in 200 adult patients with GTS (Mean age: 34.9 +/- 11.8 years). Patients were recruited from three outpatient departments in Germany and completed a semi-structured, self-rating interview. HrQoL was measured using the EQ-5D. Depression was assessed using the Beck's depression inventory (BDI) and clinical symptoms using the Yale Tourette syndrome symptom list (TSSL) and the Shapiro Tourette-syndrome severity scale (STSSS). Multivariate regression analyses were performed to identify independent predictors of HrQoL. Patients with GTS proved to have a worse HrQoL than a sample from the general German population. The domains most affected were anxiety/depression (57.1%), followed by pain/discomfort (47.5%), usual activities (38.4%), mobility (14%), and self-care (6.6%). The mean EQ-5D visual analog scale (EQ-VAS) was 65.4 +/- 21.9. The patients had a mean BDI score of 12.3 +/- 9.9, which was considerably worse compared to a healthy group who had a score of 6.45 +/- 5.2. The mean STSSS value was 3.2 +/- 1.1. In multivariate analyses, depressive symptoms contributed considerably, whereas the severity of symptoms as well as age only contributed minimally to HrQoL in the model (R(2) = 0.54). HrQoL is considerably reduced in adult patients with GTS. The main independent factors for determining HrQoL were depression, severity of symptoms, and age. Although, treatment of tics is important, co-morbidities such as depression should be diagnosed and treated vigorously.

Abstract
Gilles de la Tourette's syndrome (Tourette's syndrome; TS) is an inherited tic disorder commonly associated with other neurobehavioural conditions such as attention-deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD). While the clinical presentation of TS and other features of this disorder have been well characterized, the genetic and neurobiological basis of the disease remains incompletely elucidated. The suggestion of a central role of dopamine in the aetiology of TS has been made on the basis of experimental studies, evidence from neuroimaging studies and the therapeutic response patients with TS have to agents that antagonize or interfere with putative dopaminergic pathways. Tetrabenazine is such an agent; it depletes presynaptic dopamine and serotonin stores and blocks postsynaptic dopamine receptors. In clinical studies, tetrabenazine has been found to be effective in a wide range of hyperkinetic movement disorders, including small numbers (<50) of patients with TS in some studies. Results of a retrospective chart review enrolling only patients with TS (n = 77; mean age approximately 15 years) showed that 2 years' treatment with tetrabenazine resulted in an improvement in functioning and TS-related symptoms in over 80% of patients, findings that suggest that treatment with tetrabenazine may have long-term benefits. The authors' experience with 120 heavily co-medicated patients with TS confirms these findings. Long-term (mean 19 months) tetrabenazine treatment resulted in a Clinical Global Impressions of Change scale rating of 'improved' in 76% of patients. Such findings are promising and suggest that tetrabenazine may be suitable as add-on therapy in patients for whom additional suppression of tics is required.
