Examining Inhibitory Control Deficits in ADHD and mTBI Using the Go/No-go Task: An ERP study

Attention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder affecting approximately 8-12% of school-aged children, characterized by inattention, hyperactivity, and impulsivity (Delgado, 2009). Mild traumatic brain injury (mTBI), also known as concussion, is referred to as a frequent form of traumatic brain injury that typically presents symptoms such as headaches, fatigue, and cognitive impairments (McInnes et al., 2017). A core deficit of ADHD is inhibitory control impairment (Johnstone et al., 2009). Similarly, previous research indicates that both children with mTBI and ADHD exhibit deficits in response inhibition, a critical component of executive functioning (Ornstein et al., 2013). Our study examined whether Event-Related Potential (ERP) indices of components can effectively differentiate children and adolescents with ADHD from neurobehavioral typical and mTBI.
