Abstract

Introduction: The cognitive slowing is considered an early sign of cognitive motor disorder associated to HIV and natural aging, the best field where it has been described. However, there are no reports that establish a precise relationship between the effect of the virus and age on cognitive dynamic. Objective: To describe and identify similarities and differences in the dynamic pattern of cognitive slowing of these groups. Method: 48 asymptomatic HIV-positive, 35 healthy elder adults and 80 seronegative controls were compared with each other, during the execution of increasing difficulty and automated processing tasks, using a procedure of behavior splitting of the reaction time. Results: There is a similar cognitive slowing pattern in asymptomatic HIV-positive and elderly, characterized by the intervention of at least two factors, one of additive general slowing consisting of an exclusive reduction of speed and the other one, related to attentional control limitations during processing complexity. Conclusions: The similarity found suggests that the neurotropic virus action mimics the action of age on cognitive functioning, a fact that could be interpreted in terms of a "premature aging" of these functions. The implications of this result for public health are analyzed.
