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 .
Childhood methylphenidate treatment of ADHD and response to affective stimuli
Neural correlates of emotional dysregulation in attention-deficit/hyperactivity disorder ( ADHD ) and persisting influence of Methylpheni date ( MPH ) still remain insufficiently understood . Decreased activation in the subgenual cingulate and the ventral striatum were found during the perception of positive and negative affective pictures in drug-naïve males with ADHD during childhood ( n=10 ) . Males with ADHD during childhood treated with MPH ( n=10 ) did not show any significant differences compared to healthy controls ( n=10 ) . Further prospect i ve studies need to clarify direct and indirect mechanisms of MPH treatment that may contribute to emotional processing , which is dysfunctional in males without pharmacological treatment in childhood
