title: Comparison between the efficacies of Risperidone with Haloperidol in the treatment of attention-deficit hyperactivity disorder (ADHD) among preschoolers: a randomized double-blind clinical trial.
abstract: BACKGROUND
  Attention-deficit hyperactivity disorder (ADHD) is a common psychiatric disease with a worldwide pooled prevalence of 5.29%.
  
  
  OBJECTIVE
  To compare the efficacy of Risperidone with Haloperidol in the treatment of attention-deficit hyperactivity disorder (ADHD) among 3- to 6-year-old children.
  
  
  METHODS
  In a 6-week double-blind clinical trial, the efficacy of Risperidone 0.5-2 mg with a dose of maximum Haloperidol 0.075 mg/kg was assessed in 39 children aged 3-6 years. This study was conducted at the Golestan Psychiatric Clinic (Ahvaz, Iran). Measurement tools included the Conners' Parent Rating Scale (CPRS-48), Children's Global Assessment Scale (CGAS), and the Attention Deficit Hyperactivity Disorder Rating Scale (ADHD-RS). Data were analyzed using the Wilcoxon, Mann-Whitney, and Fisher's exact tests in the SPSS 19.
  
  
  RESULTS
  During the 6 weeks, the decline in points was seen in Conner's rating scale and in ADHD-RS score in Risperidone and Haloperidol groups (p<0.001). On the CGAS scale, an increase of performance in both groups for six weeks was statistically significant (p<0.001). In the scales of ADHD-RS and CPRS-48, no statistically significant difference was observed between the two treatment groups; i.e., in terms of reducing the rate during weeks of two, four, and six (p>0.05).
  
  
  CONCLUSIONS
  Haloperidol and Risperidone possibly can be an acceptable treatment choice in the ADHD treatment of 3- to 6-year-old children.
  
  
  BACKGROUND
  The trial was registered at the Iranian Registry of Clinical Trials (http://www.irct.ir) with the Irct ID: IRCT2015082623766N1.
