Unilateral Neglect is a complex syndrome characterized by an inability to attend to or act upon stimuli in the space contralateral to a brain lesion (without any access to consciousness). The diagnosis depends on the application of tests, not always normalized to the healthy population in each country.
To obtain normative data for the Behavioural Inattention Test (BIT) in the Portuguese population.
The test was applied to 72 healthy individuals (without clinical evidence of cognitive deterioration or psychiatric illness). Fifty individuals were females and twenty-two males, aged between 20 and 82 years (48,5±17,5) and a mean educational level of 8,4±6,3 years. The results were calculated for each subtest and also for the total score. We compared their performance according to the gender, age and educational
A main effect of the educational level was disclosed, with significant differences between the illiterate group and the others (p<.01). We did not find any gender or age effect. Star cancellation, copy and representational drawing, picture scanning and coin sorting were the subtests that were more sensitive to the educational level. Using the original diagnostic criteria of BIT without correction for educational level, a considerable part of our healthy population would have been diagnosed with neglect.
The BIT results must be corrected for the Portuguese population. The educational level and the pattern of errors/omissions play an important role on the performance of this test. More educated people seem to use better strategies in visual scanning tasks.
