ADHD
Conditions
Brief summary
The purpose of this study is to evaluate performance on the Attention Deficit Hyperactivity Disorder ( ADHD) Battery of the Cambridge Automated Neuropsychological Test Battery (CANTAB), including spatial working memory, inhibitory control, and attention while using either a noise cancelling headphone or sham headphone control in the presence of standardized auditory distractors in children and adolescents with ADHD.
Detailed description
This will be a proof-of-concept, randomized, within-subject cross-over design with the administration of noise cancelling headphones or sham headphones on two separate study days. Following screening and a baseline assessment session with no headphones, participants will be assigned to complete each experimental session. During each session, they will undergo the CANTAB and Academic tasks. The order of sessions will be randomized and balanced across participants to be either noise-cancelling headphones first followed by sham headphones; or sham headphones first followed by noise-cancelling headphones. Eligible participants currently taking stimulant medications for ADHD will be asked to stop taking their medication on the day of the baseline visit and during the 2 experimental sessions.
Interventions
During the 2 experimental sessions, participants will complete study assessments using either a noise cancelling headphone first (session 1) and then sham control second ( session 2), or vice versa, in the presence of noise distractions.

Inclusion criteria
* Age 6 to 17 at the time of parental informed consent. * Male or female. * Confirmed ADHD diagnosis at screening visit established via MINI-KID (version 7.0.2) administered by a trained clinician. * Screening ADHD-RS-IV score ≥24. * Estimated IQ (measured with the KBIT-2) ≥80. * If currently medicated with a stimulant medication (amphetamine or methylphenidate formulation), off drug on day of Baseline and Experimental Sessions.

Exclusion criteria
