We would like to congratulate Aprahamian et al. (2011) for their initiative to investigate the psychometric properties of the Cambridge Cognition Examination (CAMCOG) in assessing the cognitive status of the Brazilian elderly. This instrument is very frequently used in Brazil, but its measure characteristics have not yet been fully determined. Of course, cross-cultural adaptation and validation are rarely a simple procedure, often demanding a research program to completely adapt the tool to the specific language, culture, and selected population. In our opinion, the paper “Can the CAMCOG be a good cognitive test for patients with Alzheimer's disease with low levels of education?” (Aprahamian et al., 2011) is welcome as another trial by Brazilian scientists in this ongoing process. Notwithstanding, we believe that some comments about the methodological aspects of the paper are in order.
