The diagnostic criteria of a specific behavioral disorder following brain injury depend on the opinions of specialists with expertise for the particular behavior. Such criteria are open to criticism. In their study of compromised visual search in hemianopic patients, Kerkhoff et al1 excluded patients with unilateral neglect syndrome by their line bisection results (which were biased toward the ipsilesional end of the line) or their drawings from memory (which omitted details in the contralesional direction). Thus, patients with hemianopia were considered not to have neglect because on line bisection their errors were insignificant or were significantly opposite the side of the brain lesion (ie, toward the hemianopic field) and they made no omissions in drawing.2
Despite these differences, both nonneglect and neglect patients showed impaired contralesional search on perimetry, contralesional inattention during daily living activities, and similar improvement following visual search therapy.1,2 Thus, while the groups differed
