Abstract

Background: Neurofibromatosis type 1 (NF1) is a neurodevelopmental genetic disorder associated with visual–spatial and visuomotor deficits, which have not been studied well in adults with NF1. Methods: In 22 adults with NF1 and 31 controls, visuomotor functioning was assessed by measuring eye latency, hand latency and hand accuracy during visuomotor tasks. Visual–spatial functioning was assessed by measuring eye movement responses during the Visual Threshold Task. Results: The NF1 group had a significantly shorter eye latency than the control group and was less accurate in their hand movements during specific visuomotor tasks. The groups showed no differences in eye movement responses during the Visual Threshold Task and in hand latency during the visuomotor tasks. Conclusions: In contrast to studies in children with NF1, we found no alterations in visual–spatial information processing in adults. Impairments in eye latency and hand accuracy during specific visuomotor tasks may indicate deficits in visuomotor functioning in adults with NF1.
