We report a 61-year-old woman with left hemispatial neglect, anosognosia for hemiplegia, asomatognosia, and confabulation following a right posterior artery territory infarction. Interestingly, she believed that her plegic left arm belonged to her grandson or sometimes was her grandson himself (personification). We investigated possible underlying explanations for this personification, which included autotopagnosia, body schema delusion, visuoperceptual deficit, and asomatognosia theories. Among these, a combination of asomatognosia (“This arm is not mine”) and confabulation (“This arm belongs to my grandson”) may best account for the personification phenomenon in our patient.
