title: Postural sway in children from pedigrees exhibiting a high density of alcoholism.
abstract: A total of 98 children participated in a study of the neurobehavioral characteristics of individuals from pedigrees in which there was a high density of alcoholism. Two groups of children were evaluated (High and Low Risk) using a sensitive movement platform and a variety of methods to challenge the motor system. High-Risk children showed a greater decrement in postural steadiness when visual input was removed than did Low-Risk children. Additionally, the monopedal stances revealed hemispheric differences in postural sway as a function of risk status. The amount of sway exhibited was correlated with the latency of P300 recorded using a visual task. Both appear to be indicators of neuropathological changes. The present results suggest that postural sway may be a neurobehavioral marker for alcoholism risk.
