Abstract

The aim of the present study is to identify early markers of neurodegenerative syndromes like Alzheimer disease. To this end, weconsider important to explore those neurocognitive changes occurring during object, face and facial expression visual processingin pathological versus typical aging. In the present neuropsychological study 4 elderly people without cognitive impairment, 4 withmild cognitive impairment and 4 with moderate cognitive impairment have participated. All of them completed several visualtasks for evaluating medium and high processing levels: 4 including meaningless and meaningful object processing (mediumlevel) and 6 related to face processing (high level), 4 of them concerning facial identity and 2 concerning emotional expressions.According to our results, healthy elderly people didn’t show the global (versus local) precedence found in younger people inprevious studies in relation with Navon tasks. On the other hand, the performance of elderly people with cognitive impairmentin some of object and face processing tasks was very poor when compared with elderly people without cognitive impairment.Moreover, we found some differences among the participants of both groups of cognitive impairment. As a conclusion, wehighlight the importance of assessing both paths of ventral and dorsal visual processing through both high and medium leveltasks as those used in the present study, in order to defne early markers of cognitive impairment
