Detailed Description

Both probiotics and placebo groups will receive medication with Ritalin in a dose-dependent manner, starting at the onset of the study and simultaneous with probiotic supplementation. Children weighed 30 Kg or less receive 0.3 mg/kg of Ritalin in 3 separate intervals and after four weeks the dosage will increase to 0.5mg/kg. Those who weighed more than 30 kg receive 0.5 mg/kg with the same pattern that reaches the highest point of 0.7 mg/kg by week four. Each dosage will be administrated trice a day with breakfast, lunch, and dinner. In the middle of the study patients who consumes less than 80% of their supplements will be omitted from the study.

Interventions

  • Other: Placebo
    • The placebo capsules will be administered once a day. medication with Ritalin starts at the onset of the study in a dose-dependent manner and simultaneous with placebo supplementation.

Arms, Groups and Cohorts

  • Active Comparator: Probiotic
    • The probiotics capsules contain 7 strains of friendly bacteria (Lactobacillus casei PXN 37, Lactobacillus rhamnosus PXN 54, Streptococcus thermophilus PXN 66, Bifidobacterium breve PXN 25, Lactobacillus acidophilus PXN 35, Bifidobacterium longum PXN 30, Lactobacillus bulgaricus PXN 39)
  • Placebo Comparator: Placebo
    • Placebo capsules have an identical appearance to probiotic capsules and contain microcrystal cellulose.
