Brief Summary:
Background: The current study aimed to explore the possible effect of stimulants on oxytocin (OT), a neuropeptide found to regulate social behavior, as a mediator of the pro-social effect of methylphenidate (MPH) in children with attention deficit hyperactivity disorder (ADHD) compared to healthy controls (HCs). Methods: In a double-blind manner the investigators compared the performance of 50 children with ADHD and 40 HCs in "theory of mind" (ToM) tasks and examined the effect of a single dose of MPH/placebo on ToM and salivary OT levels in children with ADHD at baseline and following an interpersonal interaction.

Arm Intervention/treatment
Experimental: ADHD group
This group was examined twice - once after taking Ritalin and once after taking placebo
Drug: Ritalin
Single dose of Ritalin IR 0.3-0.5 mg/kg OR placebo

No Intervention: Healthy control

Primary Outcome Measures :
  1. changes in scores of ToM test [ Time Frame: 20 minutes ]
    ToM test - consists of vignettes, stories, and drawings about which the child has to answer a number of questions.

  2. changes in scores of Faux-Pas Recognition test [ Time Frame: 15 minutes ]
    number of faux-pas recognized in specific vignettes by participants

  3. changes in Oxytocin salivary level [ Time Frame: 2 hours ]
    Oxytocin salivary levels as measured three/two times during the examination (ADHD group and healthy control accordingly).
