Objective: To examine whether the CBS or BIT is potentially more sensitive to spatial disability, and whether the CBS better identifies spatial-motor exploratory symptoms. Background Spatial neglect, common after right stroke, is a failure to perceive or respond to contralesional stimuli, causing functional disability. It is strongly linked to adverse hospitalization and rehabilitation outcomes. Consistent assessment to identify survivors with spatial neglect for early treatment might reduce the cost of care, but it is unclear whether widely-used diagnostic tests such as the Catherine Bergego Scale (CBS) or the Behavioural Inattention Test (BIT) differ in identifying patients for treatment. We previously suggested that the CBS may be more sensitive to spatial-motor exploratory network dysfunction (Verdon et al., 2010) and disability (Goedert et al., in press). Design/Methods: We performed a retrospective analysis of eighty-seven consecutive patients (mean age 65) screened for spatial neglect using conventional cut-off scores (BIT 11). Results: The CBS and BIT were very consistent in quantifying spatial neglect with a linear regression r = 0.7. After excluding patients falling within 5% of the cut-off to account for random variability, 64 survivors fell into three groups: those demonstrating neglect on BIT-only (n=7), CBS-only (n=1), or on both (n=56). We expected spatial motor-exploratory deficits may be more identified by the CBS, and more disabling. Indeed, patients in the BIT-only group were less disabled, with higher Barthel scores, and had less tactile extinction, consistent with previous characterization of “where” perceptual-attentional bias (Goedert et al., in press). Conclusions: Overall, the CBS and BIT were consistent and correlated when identifying spatial neglect. However, our data suggests that patients identified on the BIT alone may have primarily “where” perceptual-attentional symptoms, and may be less disabled. This may be important to assign treatments or predict recovery of specific tasks (e.g. driving).
