Abstract Background The Montreal–Toulouse Language Assessment Battery — Brazilian version (MTL-BR) provides a general description of language processing and related components in adults with brain injury. Objective The present study aimed at verifying the criterion-related validity of the Montreal–Toulouse Language Assessment Battery — Brazilian version (MTL-BR) by assessing its ability to discriminate between individuals with unilateral brain damage with and without aphasia. Methods The investigation was carried out in a Brazilian community-based sample of 104 adults, divided into four groups: 26 participants with left hemisphere damage (LHD) with aphasia, 25 participants with right hemisphere damage (RHD), 28 with LHD non-aphasic, and 25 healthy adults. Results There were significant differences between patients with aphasia and the other groups on most total and subtotal scores on MTL-BR tasks. Conclusions The results showed strong criterion-related validity evidence for the MTL-BR Battery, and provided important information regarding hemispheric specialization and interhemispheric cooperation. Future research is required to search for additional evidence of sensitivity, specificity and validity of the MTL-BR in samples with different types of aphasia and degrees of language impairment.
