No trials reported serious adverse events .
Subgroup analysis by dose did not identify any significant differences in effect on our primary outcomes between low- , medium- or high-dose ranges .
We found that short-term use of methylpheni date might improve symptoms of hyperactivity and possibly inattention in children with ASD who are tolerant of the medication , although the low quality of evidence means that we can not be certain of the true magnitude of any effect .
There was no evidence that methylpheni date has a negative impact on the core symptoms of ASD , or that it improves social interaction , stereotypical behaviours , or overall ASD .
BACKGROUND Children with autistic spectrum disorder ( ASD ) frequently present with inattention , impulsivity and hyperactivity , which are the cardinal symptoms of attention deficit hyperactivity disorder ( ADHD ) .
The effectiveness of methylpheni date , a commonly used ADHD treatment , is therefore of interest in these children .
OBJECTIVES To assess the effects of methylpheni date for symptoms of ADHD ( inattention , impulsivity and hyperactivity ) and ASD ( impairments in social interaction and communication , and repetitive , restricted or stereotypical behaviours ) in children and adolescents aged 6 to 18 years with ASD .
Improvement of facial affect recognition in children and adolescents with attention-deficit/hyperactivity disorder under methylphenidate.
INTRODUCTION AND HYPOTHESIS Some authors draw a connection between the dopaminergic pathways and emotional perception . The present study is based on that association and addresses the question whether methylpheni date and the result ing amelioration of the disturbed dopamine metabolism lead to an improvement of the facial affect recognition abilities in children with attention-deficit/hyperactivity disorder ( ADHD ) . METHODS A computer test was conducted on 21 participants , aged 7 - 14 years and with a diagnosis of ADHD - some with comorbid oppositional defiant disorder - conducted the FEFA ( Frankfurt Test and Training of Facial Affect ) , a computer test to examine their facial affect recognition abilities . It consists of two subtests , one with faces and one with eye pairs . All participants were tested in a double-blind cross-over study , once under placebo and once under methylpheni date . RESULTS AND DISCUSSION The collected data showed that methylpheni date leads to amelioration of facial affect recognition abilities , but not on a significant level . Reasons for missing significance may be the small sample size or the fact that there exists some overlapping in cerebral connections and metabolic pathways of the site of action of methylpheni date and the affected dopaminergic areas in ADHD . However , consistent with the endophenotype concept , certain gene locations of the dopaminergic metabolism as both an aetiological factor for ADHD and the deficient facial affect recognition abilities with these individuals were considered . Consulting current literature they were found to be not concordant . Therefore , we conclude that the lacking significance of the methylpheni date affect on facial affect recognition is based on this fact
