[Adequate neuropsychological evaluation of dementia].

The authors discuss the protocol of the Optimal Neuropsychological Evaluation of Dementias of Montreal and its possible application in Brazil. This protocol is important for evaluation in neuropsychological evolution of dementia of the Alzheimer type and for bringing to the fore distinct affected cognitive profiles as much on a transversal base as longitudinal. The authors believe that its application would contribute to the progress of research in neurology, as in the clear distinction between normal aging and pathological aging.
