CONTEXT Young children raised in institutional settings experience severe deprivation in social, emotional, and cognitive stimulation. Although this deprivation is likely to disrupt brain development in ways that increase the risk for psychopathology, neurodevelopmental mechanisms linking adverse early environments to psychopathology remain poorly understood. OBJECTIVE To examine whether abno...

OBJECTIVE To assess cognitive and behavioral development at preschool age of children born preterm and with low birth weight and raised in a developing country. METHODS Prospective cross-sectional study of 80 neonates born in a university hospital in southern Brazil. Neuropsychological assessment at age 4-5 years included the Wechsler Preschool and Primary Scale of Intelligence (WPPSI), Conne...

The literature on the prevalence and stability of preschool problems of inattention, hyperactivity, and impulsivity suggests a number of links to early literacy skills and broader school achievement. Developmental considerations in the assessment of preschool ADHD are reviewed in this paper, along with evidence for the stability of symptoms over time and the relationship between early symptoms ...

A significant discrepancy between intelligence and daily adaptive functioning, or adaptive disability (AD), has been previously found to be a associated with significant psychological morbidity in preschool children with disruptive behavior (DB). The utility of AD as a predictor of later developmental risks was examined in a 3-year longitudinal study of normal (N = 43) and DB preschool children...

participants will be introduced to the risks associated with excessive early childhood televiewing and develop an understanding of the current recommended guidelines for children’s television exposure. my research agenda in montreal (canada) addresses modifiable factors in early childhood that influence human development. from birth through the preschool years, exponential brain maturation is c...

OBJECTIVE Clinically, attention-deficit/hyperactivity disorder (ADHD) is characterized by hyperactivity, impulsivity, and inattention and is among the most common childhood disorders. These same traits that define ADHD are variable in the general population, and the clinical diagnosis may represent the extreme end of a continuous distribution of inattentive and hyperactive behaviors. This hypot...

INTRODUCTION The efficacy and safety of stimulants for the pharmacologic management of attention deficit hyperactivity disorder (ADHD) is well documented. The US Food and Drug Administration approval of additional classes of medication even within stimulant treatments expands the prescribing options for practitioners. The focus of this paper is the prodrug amphetamine stimulant, lisdexamfetamin...

OBJECTIVES The present study compared the performance of preschoolers who met Diagnostic and Statistical Manual of Mental Disorders, 4(th) edition (DSM-IV) criteria for attention-deficit/hyperactivity disorder (ADHD) to those who did not meet these criteria on a test of visual attention. The aim was to investigate whether attentional impairments in preschoolers with DSM-IV ADHD could be detecte...

Although there is substantial support for the validity of the diagnosis of ADHD, there is considerable disagreement about how to best capture developmental changes in the expression of ADHD symptomatology. The current paper examines the associations among the 18 individual ADHD symptoms using a novel network analysis approach, from preschool to adulthood. The 1,420 participants were grouped int...
