Characterizing the functioning of individuals with neurodevelopmental disorders is crucial to their diagnosis. Research has found that children with different neurodevelopmental disorders, including autism spectrum disorders (ASD), attention deficit and hyperactivity disorder (ADHD), and nonverbal learning disability (NLD), may have comorbid sympto...
This chapter briefly discusses the nonverbal learning disabilities (NLD) diagnostic criteria that are in development, provides an overview of the emerging neuroimaging and neuropsychological research underlying NLD, and discusses suggested assessment and intervention strategies. It is also important to discuss that there may be two types of NLD: me...
Today, diagnosis of attention deficit hyperactivity disorder (ADHD) still primarily relies on a series of subjective evaluations that highly rely on a doctor’s experiences and intuitions from diagnostic interviews and observed behavior measures. An accurate and objective diagnosis of ADHD is still a challenge and leaves much to be desired. Many chi...
Objective: Common methods for clinical diagnosis include clinical interview, behavioral questionnaires, and neuropsychological assessment. These methods rely on clinical interpretation and have variable reliability, sensitivity, and specificity. The goal of this study was to evaluate the utility of machine learning in the prediction and classificat...
Attention-deficit/hyperactivity disorder predominantly inattentive (ADHD-PI) and combined (ADHD-C) presentations are likely distinct disorders that differ neuroanatomically, neurochemically, and neuropsychologically. However, to date, little is known about specific white matter (WM) regions differentiating ADHD presentations. This study examined di...
Social perception is an important underlying foundation for emotional development and overall adaptation. The majority of studies with children with High Functioning Autism (HFA) or nonverbal learning disabilities (NLD) evaluating social functioning have used measures of parent and/or teacher ratings. The present study utilized parent and teacher r...
The ability for neuroimaging to now explore brain structure and functioning variations has opened new avenues of research in gender differences (Cairns, Malone, Johnston, & Cammock, Personality and Individual Differences, 6, 653–654, 1985; Gur et al., Science, 267(5197), 528–531, 1995; Kulynych, Vladar, Jones, & Weinberger, Cerebral Cortex, 4(2), 1...

models of neuropsychological intervention have been expanding in recent years. In an effort to provide...
The way structures in the developing brain are related to changes in psychological and cognitive development is of interest
to child neuropsychologists. There are several ways that this relationship can be explored, including: (1) correlating structural
changes in the developing brain with behavioral changes, (2) investigating behavioral changes an...
For many clinicians, behavior and personality have been traditionally evaluated by assessing behavior patterns and interpolating these behaviors as reflecting underlying personality variables (Martin, 1988). Behavior has been defined as the what a child does with personality defined as the why the child does what he or she does. Behaviors can be qu...
Though relatively rare compared to neurodevelopmental disorders, acquired neurological disorders and diseases represent some
of the more common disorders seen by child clinical neuropsychologists. This chapter uses a transactional neuropsychological
approach to review traumatic brain injury in children; exposure to teratogenic agents, including alc...
When a practitioner begins an assessment there are three major parts to the evaluation. These sections include the intake
interview, the assessment, and the feedback. Each of these areas will be described in greater detail as well as the mechanics
of neuropsychological report writing.
The purpose of this chapter is twofold. First, we will briefly review three generally accepted approaches to neuropsychological
assessment. Second, we will present our transactional assessment approach. This discussion will include evaluation methods
for selected functional areas of the central nervous system. The conceptual framework underlying ea...
Neuronal development proceeds in an orderly fashion during development of the embryo and fetus. There are certain stages of
development that are consistent across individuals during gestation. Following birth, changes in the brain are related to
genetics, biology, and environmental stimulation. This chapter will provide an overview of development p...
Externalizing disorders have been defined as those disorders in which overt behavior is present (American Psychiatric Association
[APA], 2000). Externalized disorders are characterized by numerous dysfunctional behaviors, which pose difficulties in management
in the social and psychological aspects of the child’s life. The externalized disorders to...
