Neurobehavioral test strategies for environmental exposures in pediatric populations

The Agency for Toxic Substances and Disease Registry convened a workshop in Atlanta, GA, that evaluated approaches and methods to ascertain whether there are neurobehavioral sequelae to children and adults exposed to hazardous substances in the environment. This article, developed from that workshop, addresses the feasibility of employing extant neurobehavioral tests to screen pediatric populations. A matrix lists basic functions to be assessed during eight developmental periods ranging from birth to high school. The best of these neurobehavioral tests for pediatric populations and the types of assessment tools that are still needed are discussed. We make 10 specific recommendations to establish a hazardous substances neurobehavioral screen for pediatric populations, including appointing a review panel, developing a structured questionnaire, convening a conference on design and analysis, addressing minority and socially disadvantaged populations, coordinating adult and child assessment methods, information sharing among Federal agencies, baseline data, methodology research, research associated with hazardous worksites, and establishment of a pediatric databank.
