[Writing disorder using a word processor: role of the left hand].
A young female secretary developed a writing disorder, exclusively expressed when using a word processor, following an ischemic vascular event involving the insula and the right posterior parietal region. There was no disturbance of laterality. The neurological examination, completed by neuropsychological tests eliminated any persistent phasic or gnostic disorders. The analysis of the text produced revealed abnormalities leading to the conclusion that the left hand was responsible for all the errors observed. A sensorimotor integration disorder produced a melokinetic apraxia which appeared to be the cause of the writing disorder which would have most likely remained unknown had the subject not been a secretary.
