Akinetopsia on Driving

Abstract Akinetopsia is a quite rare symptom. Two types of akinetopsia have been reported: one is cinematographic vision, and the other is invisibility of moving objects. These symptoms are thought to occur due to dysfunction of the MT/V5 area at the occipitoparietal region. I herein describe a 54-year-old man who collided with a car parked on the left side of the road while driving. He complained that the parked car looked to be moving forwards and he could not stop his car when he noticed that it was parked. Magnetic resonance imaging disclosed the fresh infarction on the right temporoparietal region involving the MT/V5 area. His symptom during driving was considered cinematographic vision and it was the cause of the traffic accident. Akinetopsia resulted in illusory kinetopsia on driving and the traffic accident.
