Q10 Ubiquinol in Autism Spectrum Disorder and in Phelan-McDermid Syndrome.

This double-blind, cross-over, randomized, controlled trial (RCT) has the aim of evaluating the effectiveness of a metabolic support therapy in two cohorts of patients with idiopathic Autism Spectrum Disorder or Phelan-McDermid syndrome, commonly associated with syndromic autism. Each patient will receive Q10 ubiquinol + Vit. E and B for 4 months and only Vit. E and B for 4 months in a double-blind, cross-over design. Primary outcome measures of efficacy include Vineland Adaptive Behavior Scales, Childhood Autism Rating Scale, Clinical Global Impression-Improvement and Visual Analog Scales; secondary outcome measures include several questionnaires and tests of autism, cognitive function, problem behaviors, quality of life, communication and comorbid disorders, as well as measures of oxidative stress.
