Sublingual Glycine vs. Placebo on Attentional Difficulties and Hyperactivity in Prepuberal Children

This study is designed to investigate effects on attentional performance and motoric activity of 100 mg microencapsulated glycine (Bidicin® from Biotiki®) compared to placebo after treatment with t.i.d. sublingual doses over 3 weeks each. The primary objective of the study is to determine the effects on attentional performance and motoric activity of 100 mg microencapsulated Glycine (Bidicin® from Biotiki® ) compared to placebo after treatment with t.i.d. sublingual doses over 3 weeks each in children with low attentional performance and high motoric activity. A number of 30 prepuberal boys and girls aged 6 - 14 years with low attentional performance and high motoric activity will be enrolled in this study. The prepuberal status will be determined by Tanner stages ≤ 3.
