Introduction Attention Deficit Hyperactivity Disorder (ADHD) a neurobehavioral and cognitive disorder that is characterized by inattentive, impulsive and hyperactivity symptoms (Ko et al., 2013). It is a highly prevalent disorder among child and adolescent populations although approximately 15% of patients have been found to meet full symptom criteria into adulthood (Hoogman et al., 2013). ADHD has been related to various cognitive deficits in major areas of executive functioning such as planning, working memory decision making, goals setting, emotional attending (Ernst et al., 2003; Ko et al., 2013; Hulvershorn et al., 2014). In the past several decades, as technology has advanced and become more available for research purposes, researchers have been interested in looking at the neurological substrates that underpin Attention Deficit Hyperactivity Disorder. Many studies since have found that abnormalities in various regions of the brain are closely associated with specific behavioral and cognitive deficits that that are characterized by ADHD.
The purpose of this paper is to examine more in depth the neurological substrates and underpinnings of ADHD and its associated behavioral deficits. An extensive review of the past research in this area has revealed a myriad of different brain regions and networks which are related to various deficits and behaviors in individuals who have ADHD. I will be describing and discussing the general findings of these studies in hopes to
