The present study investigated neuropsychological functioning in school-age children at various points in time surrounding a hypoglycemic episode using 13 tasks drawn from age-appropriate, standard neuropsychological tests. The results demonstrate the effects of a hypoglycemic episode on neuropsychological functioning even after detectable physical symptoms have subsided. Although we are unable to delineate clearly their temporal course, it appears that the impact of such episodes is transient. In general, the pattern exhibited by these children who have presumably recovered from their mild hypoglycemic episode involved reduced motor performance, attention, and memory. The observed prolonged recovery time of these functions presents important implications for the child in both school and social settings.
