    AbstractPathological limb pain patients show decreased attention to some stimuli on the painful limb and increased attention to others, a paradox that has dogged the field for over a decade. We hypothesized that pathological pain involves a spatial inattention confined to bodily representations. Patients showed inattention to the painful side for visual processing of body parts but not letters, tactile processing but not auditory, and body-part bisection tasks but not line bisection tasks. We propose the new term "somatospatial inattention" to describe bodily-specific spatial inattention associated with pathological limb pain.© 2016 American Neurological Association.
