Immediate Effects of Methylphenidate on Vocal Acoustic Parameters in Children with Attention Deficit Hyperactivity Disorder

Abstract

Objective: The children with attention deficit hyperactivity disorder are more talkative and aloud than typical children. Children with attention deficit hyperactivity disorder might abuse their voice more often than others and this might be a risk factor for childhood dysphonia, and hyperfunctional vocal behaviors negatively influence their communications. The studies about vocal acoustic variables in children with attention deficit hyperactivity disorder are very limited; moreover possible effects of the stimulants on vocal acoustic variables are unknown. The purpose of the present study was to evaluate possible vocal acoustic changes following methylphenidate administration in children with attention deficit hyperactivity disorder.
