Exposure to cocaine: behavioral outcomes in preschool and school-age children.

Within the last 5 years, increasing numbers of children exposed prenatally to cocaine and crack have been evaluated in the preschool and school-age years. Although there are few published reports to date about the findings of longitudinal followup efforts beyond the first 12 to 24 months of age (Chasnoff et al. 1992; Griffith et al. 1994), sufficient data are beginning to emerge from animal and human studies to allow some refinement of hypotheses and more informed choices of measures for studying such children.
