Participant must be aged 13 to 19 yearsĪdditional inclusion criteria for ADHD group:.

The investigators will repeat three tests before and after taking stimulant medication. ADHD patients will be asked to come to the laboratory before taking their ADHD medication. Eligible participants will participate in two sessions (off-med and on-med conditions) conducted on the same day. 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. The proposed study will use the acoustic reflex to objectively measure auditory sensitivity to loud sounds. It remains unknown exactly how stimulant medication alters the loudness perception. With stimulant medication, individuals with ADHD become more tolerant of loud noise than when they were non-medicated. Both hypersensitivity and hyposensitivity to loud sounds are common symptoms in ADHD patients. 
Besides core ADHD symptoms (inattentiveness, hyperactivity, impulsivity), ADHD also affects the ability to perceive and process sounds. Why Should I Register and Submit Results?Īttention-deficit/hyperactivity disorder (ADHD) is the most common neurodevelopmental disorder in children.
