Disorders of development include a range of disorders first evidenced in childhood. Although most disorders have their origins in childhood, a few fully express themselves before early adulthood. This chapter describes the nature, assessment, and treatment of the more common disorders that are revealed in a clinically significant way during a child’s developing years. The disorders of development affect a range of functioning from single skills deficits to more pervasive problems that negatively impact a child’s ability to function. Included is coverage of several disorders usually diagnosed first in infancy, childhood, or adolescence, including the neurodevelopmental disorders (e.g., attention-deficit/ hyperactivity disorder, autism spectrum disorder, communication disorders, intellectual disability, and specific learning disorder) and the disruptive, impulse control, and conduct disorders (e.g., oppositional defiant disorder, conduct disorder). Recommendations for future research on the potential for advancing knowledge regarding spectrums within some of these disorders as well as recommendations for treatment are outlined.

Defiant Behavior

The Diagnostic and Statistical Manual of Mental Disorders, fifth edition characterizes oppositional defiant disorder (ODD) as reflecting pervasive patterns of irritable mood, defiant behavior, and/or vindictiveness. Youth with autism spectrum disorder (ASD) exhibit high rates of disruptive behaviors commonly associated with ODD, such as noncompliance, irritability, temper tantrums, and mood dysregulation. This chapter reviews the presentation of ODD in individuals with ASD, including current prevalence estimates, proposed etiology, validated assessment methods, and emerging best practices designed to treat challenging behaviors. Although there is a robust literature describing assessment and treatment procedures for disruptive behaviors in individuals with ASD, conceptualizing these hallmark behaviors within the framework of ODD is relatively novel and not without controversy. Discussion thus includes challenges around the applicability of the diagnostic criteria in this population and future research directions that may provide clarity on this issue.

Neurodevelopmental Hypothesis

SummaryThe neurodevelopmental hypothesis of schizophrenia provided a valuable framework that allowed a condition that usually presents with frank disorder in adolescence or early adulthood to be understood at least in part as a consequence of events occurring early in development. However, the implications of the neurodevelopmental hypothesis for nosological conceptions of the disorder can only now be fully appreciated. Recent research indicates genetic overlap between schizophrenia and syndromes in which psychopathology is manifest in childhood and that are often grouped together as ‘neurodevelopmental disorders' such as autism-spectrum disorders, intellectual disability and attention-deficit hyperactivity disorder. These findings challenge the aetiological basis of current diagnostic categories and, together with evidence for frequent comorbidity, suggest that we should view the functional psychoses as members of a group of related and overlapping syndromes that result in part from a combination of genetic and environmental effects on brain development and that are associated with specific and general impairments of cognitive function. This has important implications for future research and for the configuration of psychiatric services.

P50 Suppression

Abstract. Auditory sensory gating is commonly assessed using the Paired-Click Paradigm (PCP), an electroencephalography (EEG) task in which two identical sounds are presented sequentially and the brain’s inhibitory response to the second sound is measured. Many clinical populations demonstrate reduced P50 and/or N100 suppression. Testing sensory gating in children may help to identify individuals at risk for neurodevelopmental disorders earlier, including autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), which could lead to more optimal outcomes. Minimal research has been done with children because of the difficulty of performing lengthy EEG experiments with young children, requiring them to sit still for long periods of time. We designed a modified, potentially child-friendly version of the PCP and evaluated it in typically developing adults. The PCP was administered twice, once in a traditional silent room (silent movie condition) and once with an audible movie playing (audible movie condition) to minimize boredom and enhance behavioral compliance. We tested whether P50 and N100 suppression were influenced by the presence of the auditory background noise from the movie. N100 suppression was observed in both hemispheres in the silent movie condition and in the left hemisphere only during the audible movie condition, though suppression was attenuated in the audible movie condition. P50 suppression was not observed in either condition. N100 sensory gating was successfully elicited with an audible movie playing during the PCP, supporting the use of the modified task for future research in both children and adults.

Psychiatric Conditions

Recent research and clinical attention devoted to co-occurring psychiatric conditions within autism spectrum disorder (ASD) has led to significant advances in the understanding of and ability to assess and treat co-occurring problems effectively. This chapter summarizes those advances while also highlighting the substantial gaps that remain in the understanding of co-occurring problems in people with ASD. The chapter provides recommendations for future research directions in the areas of etiology, developmental course, assessment, and treatment. It also offers suggestions for improving the representativeness of research participants and strengthening community–academic partnerships in this important field of study.

Abstract Disruptive behaviour disorders (DBDs)—which can include or be comorbid with disorders such as attention-deficit hyperactivity disorder, oppositional defiant disorder, conduct disorder and disruptive mood dysregulation disorder—are commonly seen in paediatric practice. Given increases in the prescribing of atypical antipsychotics for children and youth, it is imperative that paediatric trainees in Canada receive adequate education on the optimal treatment of DBDs. We describe the development, dissemination, and evaluation of a novel paediatric resident curriculum for the assessment and treatment of DBDs in children and adolescents. Pre–post-evaluation of the curriculum showed improved knowledge in participants.

Assessment And Treatment

Over 60% of children diagnosed with selective mutism are also diagnosed with Autism Spectrum Disorder. Previous research established that behavioral interventions are effective at increasing speech in children with both diagnoses. However, few studies conducted assessments to determine environmental variables that inhibit speech, and such assessments are necessary for the development of effective and efficient treatments. This case study describes an assessment that evaluated the function(s) of selective mutism. The results confirmed that the participant did not talk to avoid social interaction and that mutism occurred primarily in the presence of multiple, unfamiliar people. Our first treatment focused on increasing tolerance for social interaction, demonstrated by an increase in speech production in the presence of unfamiliar people. Our second treatment focused on increasing qualitative aspects of the participant’s speech (i.e., both responses and initiations). Finally, we taught the participant’s parents to implement the treatment in naturalistic settings, and the participant demonstrated generalization of treatment effects across people and settings. Implications for clinical practice and future research are discussed.

Effective Assessment

Youth with attention deficit hyperactivity disorder experience impairment across multiple domains of functioning, with the characteristics changing with age. Thus, assessment and treatment must be appropriate for the home and school and relevant to the child’s developmental level. This chapter reviews effective assessment strategies for use with children and adolescents. Psychosocial treatments for children and adolescents are discussed separately, as the approaches with each group differ substantially. For children, strategies with a strong evidence base are described, and innovations and treatment modifications that have been examined recently are showcased. For adolescents, the results of the few randomized clinical trials conducted with this population are reviewed. A theoretical model for how to sequence treatments (i.e., intervention, medication, accommodations) for youth is referenced, and two case studies highlight this model, as well some of the new findings described in this chapter. Implications and recommendations for future research and practice are provided.

Assessment And Treatment

Schizophrenia before the age of 18 years is usually divided into two categories. Early-onset schizophrenia (EOS) presents between the ages of 13 and 17 years, whereas very-early-onset schizophrenia (VEOS) presents at or before the age of 12 years. Previous studies have found that neurodevelopmental difficulties in social, motor, and linguistic domains are commonly observed in VEOS/EOS patients. Recent research has also shown a high prevalence of neurodevelopmental disorders (e.g., intellectual disability, communication disorders, autism spectrum disorder, neurodevelopmental motor disorders) in VEOS/EOS patients, indicating genetic overlap between these conditions. These findings lend support to the neurodevelopmental continuum model, which holds that childhood neurodevelopmental disorders and difficulties and psychiatric disorders (e.g., schizophrenia) fall on an etiological and neurodevelopmental continuum, and should not be considered discrete entities. Based on this literature, in this study we focused on the overlap between neurodevelopmental disorders and schizophrenia investigating, in a large sample (N = 230) of VEOS/EOS children and adolescents, the clinical differences, at the onset of psychosis, between VEOS/EOS with neurodevelopmental disorder or neurodevelopmental difficulties and VEOS/EOS with no diagnosed neurodevelopmental disorder or neurodevelopmental difficulties. The findings showed that, in children and adolescents with a neurodevelopmental disorder or neurodevelopmental difficulties, psychosis onset occurred at an earlier age, was associated with more severe functional impairment (e.g., global, social, role), and was characterized by positive symptoms (e.g., grandiose ideas, perceptual abnormalities, disorganized communication) and disorganized symptoms (e.g., odd behavior or appearance, bizarre thinking). Instead, in children and adolescents without a neurodevelopmental disorder or neurodevelopmental difficulties, psychosis onset was mainly characterized by negative symptomatology (e.g., social anhedonia, avolition, expression of emotion, experience of emotions and self, ideational richness). Given these differences, the presence of a neurodevelopmental disorder or neurodevelopmental difficulties should be carefully investigated and integrated early into the assessment and treatment plan for VEOS/EOS patients.

The recurrent 16p11.2 microdeletion is characterized by developmental delays and a wide spectrum of congenital anomalies. It has been well reported that individuals with this ∼593-kb interstitial deletion have an increased susceptibility toward the autism spectrum disorder (ASD). Abnormalities of the eye and ocular adnexa are also commonly associated findings seen in individuals with the 16p11.2 microdeletion syndrome, although these ophthalmic manifestations have not been well characterized. We conducted an extensive literature review to highlight the eye features in patients with the 16p11.2 microdeletion syndrome and describe a 5-year-old boy with the syndrome. The boy initially presented with intellectual disability, speech delay, and defiant behavior; diagnoses of attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) were established. He had a Chiari malformation type 1. His ophthalmic features included strabismus, hyperopia, and ptosis, and a posterior embryotoxon was present bilaterally. From a systematic review of prior reported cases, the most common eye and ocular adnexa findings observed were downslanting palpebral fissures, deep-set eyes, ptosis, and hypertelorism.
