Summary

The aims of this study are to evaluate auditory sensitivity in teenagers with ADHD using acoustic reflex thresholds (ART) and to examine the effects of ADHD stimulant medication on ART.

Detailed description

Attention-deficit/hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder in children. Besides core ADHD symptoms (inattentiveness, hyperactivity, impulsivity), ADHD also affects the ability to perceive and process sounds. Both hypersensitivity and hyposensitivity to loud sounds are common symptoms in ADHD patients. With stimulant medication, individuals with ADHD become more tolerant of loud noise than when they were non-medicated. It remains unknown exactly how stimulant medication alters the loudness perception. The proposed study will use the acoustic reflex to objectively measure auditory sensitivity to loud sounds. The aims of this study are to evaluate auditory sensitivity in patients with ADHD using acoustic reflex thresholds (ART) and to examine the effects of ADHD stimulant medication on ART. Eligible participants will participate in two sessions (off-med and on-med conditions) conducted on the same day. ADHD patients will be asked to come to the laboratory before taking their ADHD medication. The investigators will repeat three tests before and after taking stimulant medication. The investigators will also conduct screening tests during and between the first and second sessions. The investigators will compare a difference between the two independent groups (ADHD vs. Control) and compare a within subject difference between medication conditions (on-med vs. off-med).

Conditions

• Attention Deficit Hyperactivity Disorder
• Attention Deficit Disorder
• Attention Deficit Disorder With Hyperactivity

Interventions

Type	Name	Description
DRUG	ADHD stimulants, for example, amphetamine, dexmethylphenidate, dextroamphetamine, methylphenidate	Both ADHD and control groups of subjects will participate in 2 sessions (on-med and off-med conditions) conducted on the same day. ADHD group will be asked to come to the laboratory in the morning before taking their morning ADHD stimulant medication. They will be tested before and after taking their ADHD medication (off-med and on-med conditions). The investigators will observe changes between the two conditions.
