[Distracter inhibition in mild cognitive impairment].

The results indicate the joint influence of normal and pathological aging processes on patients with MCI. The deceleration of the perceptual-motor components of the reaction time reflects the processes of normal cognitive aging, while the deceleration of the processing speed (in the presence of any distractors, including congruent ones) characterizes pathological cognitive aging. Differential diagnosis of normal and pathological cognitive changes is possible using data based on the analysis of reaction time components. It is important to take into account the conservativeness of responses as a factor slowing down the reaction time in pathological and normal cognitive aging.
