Deficits in eye movement control in children with fetal alcohol spectrum disorders

Compared with controls, FASD children had elongated reaction times, excessive direction errors, and no express saccades. Metric analysis of correct prosaccades revealed a trend toward increased saccadic duration and decreased saccadic velocity in FASD subjects. CONCLUSION: These results reflect deficits in executive function and motor control, and are consistent with dysfunction of the frontal lobes, possibly due to disrupted inhibitory mechanisms. Therefore, eye movement tasks may be powerful and easy tools for assessing executive function deficits in FASD.
