Review
Global developmental delay and intellectual disability are phenotypically and genetically heterogeneous and a specific diagnosis is not reached in many cases. This paper outlines a systematic approach to global developmental delay and intellectual disability.

Review
Neurodevelopmental disabilities, including autism, attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, affect millions of children worldwide, and some diagnoses seem to be increasing in frequency. Industrial chemicals that injure the developing brain are among the known causes for this rise in prevalence. In 2006, we did a systematic review and identified five industrial chemicals as developmental neurotoxicants: lead, methylmercury, polychlorinated biphenyls, arsenic, and toluene. Since 2006, epidemiological studies have documented six additional developmental neurotoxicants-manganese, fluoride, chlorpyrifos, dichlorodiphenyltrichloroethane, tetrachloroethylene, and the polybrominated diphenyl ethers. We postulate that even more neurotoxicants remain undiscovered. To control the pandemic of developmental neurotoxicity, we propose a global prevention strategy. Untested chemicals should not be presumed to be safe to brain development, and chemicals in existing use and all new chemicals must therefore be tested for developmental neurotoxicity. To coordinate these efforts and to accelerate translation of science into prevention, we propose the urgent formation of a new international clearinghouse.

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental illness that can have devastating long-term consequences if untreated. Studies have shown that untreated individuals have worse outcomes than treated patients in academic, occupational, and social functioning; antisocial behavior; driving; substance use; and use of services. Family functioning is also highly affected by the child's ADHD and should be addressed by physicians. Recognition and management of ADHD in children is important so that their long-term outcomes can be improved. Differential diagnosis should include the possibility of comorbid psychiatric disorders and other developmental disorders. Neuropsychological testing may be valuable for both diagnosis and the assessment of treatment response.

Review
Global developmental delay and intellectual disability are relatively common pediatric conditions. This report describes the recommended clinical genetics diagnostic approach. The report is based on a review of published reports, most consisting of medium to large case series of diagnostic tests used, and the proportion of those that led to a diagnosis in such patients. Chromosome microarray is designated as a first-line test and replaces the standard karyotype and fluorescent in situ hybridization subtelomere tests for the child with intellectual disability of unknown etiology. Fragile X testing remains an important first-line test. The importance of considering testing for inborn errors of metabolism in this population is supported by a recent systematic review of the literature and several case series recently published. The role of brain MRI remains important in certain patients. There is also a discussion of the emerging literature on the use of whole-exome sequencing as a diagnostic test in this population. Finally, the importance of intentional comanagement among families, the medical home, and the clinical genetics specialty clinic is discussed.

Review
Brain injury in premature infants is of enormous public health importance because of the large number of such infants who survive with serious neurodevelopmental disability, including major cognitive deficits and motor disability. This type of brain injury is generally thought to consist primarily of periventricular leukomalacia (PVL), a distinctive form of cerebral white matter injury. Important new work shows that PVL is frequently accompanied by neuronal/axonal disease, affecting the cerebral white matter, thalamus, basal ganglia, cerebral cortex, brain stem, and cerebellum. This constellation of PVL and neuronal/axonal disease is sufficiently distinctive to be termed "encephalopathy of prematurity". The thesis of this Review is that the encephalopathy of prematurity is a complex amalgam of primary destructive disease and secondary maturational and trophic disturbances. This Review integrates the fascinating confluence of new insights into both brain injury and brain development during the human premature period.

PURPOSE OF REVIEW
We review findings related to predictors, correlates, outcomes, and treatment of preschool depression that have been published in the last 3 years.
RECENT FINDINGS
Preschool depression displays a chronic course through late adolescence and is associated with temperamental and personality traits, poorer physical health, and negative parenting practices. Preschool depression predicts deficits into adolescence, including social difficulties and blunted neural response to rewards. Depressed preschoolers can experience suicidal ideation and behaviors and display an accurate understanding of the finality of death. A treatment for preschool depression has now been validated that uses the parent-child relationship to enhance emotion development and reduce depressive symptoms. Preschool depression is homotypic with depression that occurs later in life. Future work elucidating mechanisms through which preschool depression develops and informs the sub-groups for which particular treatments may be most effective will have considerable implications for prevention and early intervention.
