Effects of Eye Movement Exercise on Cognitive Function and Prefrontal Cortex Connectivity for the Elderly with Mild Cognitive Impairment: An fNIRS Study

PURPOSE The purpose of this study was to examine the effects an eye movement exercise intervention on cognitive function and prefrontal cortex connectivity in elderly with mild impairment.METHODS Ten older adults impairment participated consisting saccadic movement, pursuit vestibular-ocular vergence for 4 weeks. Cognitive (MoCA-K), reaction time during stroop task, were measured using functional near-infrared spectrometric analyzer (fNIRS) before after intervention.RESULTS First, showed significant improvement (p < .05). Second, decreased significantly from 1.16 0.91 ms exercise. Third, strength (left OFC - right FPC, FPC) increased impairment.CONCLUSIONS results suggest that is effective improving through brain connection patients impairment.
