Driving evaluation of mild unilateral spatial neglect patients–three high-risk cases undetected by BIT after recovery

Abstract

The respective driving abilities of three patients having a right hemisphere infarct and mild unilateral spatial neglect (USN) were examined. Neuropsychological examinations included the Behavioral Inattention Test Japanese version (BIT-J) and the Japanese version of the Wechsler Adults Intelligence Scale – Third edition. Their driving ability was assessed with a driving simulator test and on-road evaluation. Patients had no neglect based on the BIT-J, but showed some slight signs of USN on a driving simulator test and on-road evaluation. This study assessed risks of mild USN patient driving and explored possibilities of improving it using Advanced Driving Assistance Systems.
