Abstract

The neuritic plaques and the neurofibrillary tamgles are the main neuropathological findings in Alzheimer's disease. Nevertheless, these findings can be found in individuals with normal cognition, as well as in dementia patients with the same distribution. It is a matter of debate if these individuals harbor a cognitive reserve protecting them from Alzheimer's disease symptoms and what is the role of educational attainment over this reserve. The current study intends to identify the individuals with pre-symptomatic Alzheimer's disease and to investigate the possible protective role of education towards dementia. From the Brazilian Brain Bank of University of São Paulo, 150 elderly individuals with normal cognition and other 50 dementia patients will be selected. Clinical data will be gathered through a structured interview and scales for cognitive evaluation (CDR and IQCODE), conducted with a knowledgeable informant. Neuropathologic analysis will be conducted through imunohistochemistry techniques and cases will be evaluated through the Braak and Braak staging and the CERAD criteria. The groups will be analyzed: individuals without cognitive symptoms and neuropathological findings, patients with dementia caused by Alzheimer's disease and the group with pre-symptomatic Alzheimer's disease. Education will be compared among the three groups and the comparison will be controlled by age, gender and economical level. (AU)
