Brief summary

The purpose of this study is to measure the effects of LiQ-NOL supplementation on language production using the Clinical Evaluation of Language Fundamentals test, language sampling using the mean length of utterance test, and speech articulation using the Goldman-Fristoe Test of Articulation.

Detailed description

This is a randomized, double-blind, placebo-controlled clinical study of CoQ efficacy in a crossover design. Patients will be screened, enrolled, and studied in the outpatient clinic of the Thomas Center for Down Syndrome at CCHMC. All patients will be randomly assigned to either a liquid product (LiQ-NOL®) and an identical placebo liquid. Study drug and placebo will be administered twice a day (morning and evening).
