tic disorders/dopamine

OBJECTIVE To study a possible association between the three functional polymorphisms in the promoter region of dopamine D4 receptor (DRD4) gene and chronic tic disorder. METHODS Genomic DNA was isolated from the venous blood leukocytes of 84 unrelated patients with chronic tic disorder (Study group)

Aim: To investigate the association between circulating anti-dopamine D2 receptor (D2R) autoantibodies and the exacerbation of tics in children with chronic tic disorders (CTDs). Method:

OBJECTIVE To investigate the mRNA expression of dopamine receptor D2 (DRD2) and dopamine transporter (DAT) in peripheral blood lymphocytes before and after treatment in children with tic disorder (TD). METHODS RT-PCR was used to measure the mRNA expression of DRD2 and DAT in peripheral blood

OBJECTIVE Ziprasidone is an atypical antipsychotic with a high ratio of 5-HT(2A) to D(2) receptor antagonism. It is also an agonist at 5-HT(1A), which has been shown in rats to increase dopamine in prefrontal cortex. The objective of this study was to probe the dopamine agonist and antagonist

OBJECTIVE Tourette syndrome (TS) is characterized by motor and vocal tics, and its diagnosis is based on clinical criteria. Dopamine-blocking neuroleptics are regarded as the most effective drugs for the treatment of TS. Sulpiride is a selective dopamine D2 antagonist. However, only one study with a

OBJECTIVE The purpose of this trial was to investigate the short-term safety and efficacy of risperidone in the treatment of chronic tic disorders in children and adolescents. METHODS This was an 11-week open-label trial and included seven subjects (five boys and two girls) with a mean age of 12.9

Due to its unique pharmacodynamic properties of dopamine partial agonist activity, and its association with few and mild side effects, aripiprazole is a candidate atypical antipsychotic for patients with tic disorders. This open-label study compared the efficacy and tolerability of aripiprazole with

OBJECTIVE To evaluate the effect of Qufeng Zhidong Recipe (QZR) on the head tic behavior, and the mRNA expressions of Notch1 and dopamine D2 receptor (D2R) in tic disordered mice. METHODS Mouse model like wet-dog shake head tic disorder was established by peritoneal injection of 5-HT2A/C agonist DOI

Purpose: To investigate the effect of applying stereotactic radiofrequency thermocoagulation in the anterior limbs of patients' internal capsules in treating intractable tic disorders.Materials and methods: Patients diagnosed with intractable tic disorders were prospectively enrolled

This review summarizes animal models of Tourette syndrome (TS) and associated tic disorders that have been developed through pharmacological manipulation. These models provide a useful platform to explore the pathophysiology and the therapeutic interventions available for these disorders. The

In this article, the characterization, synthesis, as well as the photocatalysis dye degradation performance of two novel silver(I) coordination polymers, namely, [Ag(L)(Hbdc)]_n (1, L = 1,4-Bis(5,6-dimethylbenzimidazol-1-yl)butane, H₂bdc = 1,4-Benzenedicarboxylic acid) and

BACKGROUND Primarily safe and efficacious treatments for chronic tic disorders are needed. Also needed are such treatments that target co-morbid conditions. Aripiprazole, a dopaminergic/serotonergic agent with partial agonist properties at the D2 dopamine receptor and 5-hydrdoxytryptamine 1A

OBJECTIVE Primary tic disorders are complex, multifactorial disorders in which tics are accompanied by other sensory features and an array of comorbid behavioral disorders. Secondary tics are proportionally much less frequent, but their etiology is diverse. This review aims to guide clinicians in

Family, twin and segregation analysis have provided evidences that genetic factors are implicated in the susceptibility for obsessive-compulsive disorder (OCD). Several lines of research suggest that the dopaminergic system may be involved in the pathophysiology of OCD. Thus, the aim of the present
