概要 BACKGROUND: Perseveration has been observed in a number of behavioural contexts, including speaking, writing, and drawing. However, no previous report describes patients who show perseveration only for drawing a human figure. OBJECTIVE: The present report describes a group of patients who show body awareness-related cognitive impairment during a human figure drawing task, a different presentation from previously described neuropsychological cases. METHODS: Participants were 15 patients who had a frontal lobe brain tumour around the insula cortex of the right hemisphere and had subsequently undergone a neurosurgical resective operation. Participants were asked to draw a human figure in both"hands-down"and"hands-up"configurations. RESULTS: Eight of the 15 patients drew a human figure with six fingers during the"hands-up"and the"hands-down"human figure drawing tasks (one patient drew eight fingers). A statistical analysis of potential lesion areas revealed damage to the right anterior frontal insula and operculum in this group of patients relative to the five-finger drawing group. CONCLUSIONS: Our findings reveal a newly described neuropsychological phenomenon that could reflect impairment in attention directed towards body representations.
