Abstract: ObjectiveTo examine the occurrence rate of visuospatial hemi-neglect of patients with cerebral injury with behavioural inattention test (BIT) (Japanese version),and assess the validity of the BIT test.Methods22 subjects (16 with right hemispheric damage and 6 with left hemispheric damage) were tested with BIT. ResultsThe rate of visuospatial hemi-neglect in 22 patients with hemispheric damage was 36.4% (8 cases) , and that rate in 16 patients with right hemispheric damage was 31.3% (5 cases), in 6 patients with left hemispheric damage was 50% (3 cases).ConclusionThe occurrence rate of visuospatial hemi-neglect appears to be independent from male or female, age, course of disease and education level of study subjects.
