Several studies describe the association between TS and attention deficit hyperactivity disorder(ADHD). Fifty percent of children diagnosed with ADHD have comorbid tic disorder. ADHD related symptoms have been reported in 35% to 90% of children with TS. Since ADHD is the most prevalent comorbid condition with TS and those with concomitant TS and ADHD present with considerable psychosocial and behavioral impairments, it is essential for clinicians to be familiar with these diagnoses and their management. This paper highlights the association between treating ADHD with stimulants and the development of tic disorders. The two cases discussed underscore the fact that children with TS may present with ADHD symptomatology prior to the appearance of any TS related symptoms. Appropriate management of TS in a patient diagnosed with ADHD can lead to quality of life improvements and a reduction in psychosocial impairments.展开更多

Methods: Model rats with hyperactivity of liver-yang hyperactivity were prepared using male SD rats.Once successful, the rats were randomly divided into groups and given medicine by gavage for 4 weeks. Blood wascollected from the abdominal aorta to prepare serum. Serum nitric oxide (NO) concentration was determined bychemical colorimetry. The contents of ET, TXB2 and 6-K-PGF1a were determined by enzyme linked immunosorbentassay (ELISA). Results: Compared with the control model group, the blood pressure, serum ET and TXB2 of rats in thewind dispelling medicine group was not significantly reduced, while those of rats in captopril group, Tianma GoutengDecoction I group (TGD group) decreased significantly (P 〈0.05 for both). Interestingly, the blood pressure, serum ETand TXB2 of rats in the combination group (wind dispelling medicine & TGD) decreased significantly compared withboth wind dispelling medicine group and TGD group. Meanwhile, the levels of serum NO and 6- K-PGF1a in thecombination group was much higher than those in the wind dispelling medicine group or TGD group (P 〈0.05 for both).However, the levels of serum NO and 6- K-PGF1a in the wind dispelling medicine group was not significantly increasedcompared with the model group. Conclusion: There is no direct pressure lowering effects of wind dispelling medicinealone, while wind dispelling medicine could potentiates the antihypertensive effects of Tianma Gouteng Decoction I.Besides, the synergistic effects may be related to decreased ET and TXB2 levels and the increased NO and 6- K-PGF1alevels.展开更多

Tic disorders(TD) are common co-morbidities in paediatric ADHD patients with or without pharmacotherapy treatment. There has been conflicting evidence of the role of psychostimulants in either precipitating or exacerbating TDs in ADHD patients. We carried out a literature review relating to the management of TDs in children and adolescents with ADHD through a comprehensive search of MEDLINE, EMBASE, CINAHL and Cochrane databases. No quantitative synthesis(meta-analysis) was deemed appropriate. Metaanalysis of controlled trials does not support an association between new onset or worsening of tics and normal doses of psychostimulant use. Supratherapeutic doses of dextroamphetamine have been shown to exacerbate TD. Most tics are mild or moderate and respond to psychoeducation and behavioural management. Level A evidence support the use of alpha adrenergic agonists, including Clonidine and Guanfacine, reuptake noradrenenaline inhibitors(Atomoxetine) and stimulants(Methylphenidate and Dexamphetamines) for the treatment of Tics and comorbid ADHD. Priority should be given to the management of co-morbid Tourette's syndrome(TS) or severely disabling tics in children and adolescents with ADHD. Severe TDs may require antipsychotic treatment. Antipsychotics, especially Aripiprazole, are safe and effective treatment for TS or severe Tics, but they only moderately control the co-occurring ADHD symptomatology. Short vignettes of different common clinical scenarios are presented to help clinicians determine the most appropriate treatment to consider in each patient presenting with ADHD and co-morbid TDs.展开更多
