Evaluation of cognition with the eyelink: Saccadic eye movements in healthy subjects

Background The aim of this study is to determine the normative data eye movements models for healthy individuals between ages 18-77. Method 76 subjects were included in 3 age groups as 18-44, 45-59, 60+. Neuropsychological assessment with five cognitive domains, was applied. EyeLink 1000 Plus used record and pro-saccade anti-saccade movement paradigms. Amplitude, latency, anticipatory saccades, express correct saccade response, corrected uncorrected responses analyzed. Result In antisaccade results, amplitude, saccade, significantly different (p<0.05). Significant difference also found prosaccade latency (p<0.001). 18-44 group, executive functions highly negatively correlated (r = -0.744, p 0.000), language meanly -0.514, -0.010). 45-59 a medium level negative correlation observed -0.501, 0.025). Language -0.515, 0.020) year group. 60+ attention -0.414, 0.021). -0.396, 0.027) weakly correlated. Conclusion Decline that occur aging might affect movements. relationship antisaccades our preliminary may attract evaluation cognition.
