RESUMO

We investigated the orienting of visual attention in patients with Parkinson?s disease (PD), healthy elderly and young subjects. Five Reaction Time (RT) and Temporal Order Judgment (TOJ) experiments were performed in order to evaluate automatic and voluntary attention and perception of temporal order. The PD patients exhibited a deficit when compared to the healthy elderly subjects in voluntary attention, perception of temporal order and mental flexibility, but had similar results in the automatic attention task. The correlation between the values obtained in RT and TOJ experiments was significant, which points towards a common mechanism underlying deficits of PD patients and effects of aging: attention.
