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.
