A Study of Evaluation of Vision Training System to Prevent Mild Cognitive Impairment

Scientists have long purported a connection between function vision and dementia: for example, deficits in visuospatial cognition are a common symptom of Alzheimer’s disease. Recently, we have seen an increase in the researches aiming to detect dementia early through the quantification of brain processes involved in stereopsis in humans [9]-[10]. In this study, we developed two 3D visual training tasks, involving depth perception and eye movements, and analyzed how regional cerebral hemodynamics changed during their performance utilizing functional near-infrared spectroscopy (fNIRS). The 3D-vision training paradigm comprised two tasks, train the predictive ability and short-term memory and present them using stereoscopic content. This combination resulted in an overall rise in blood flow/neural activation in specific regions throughout the brain, especially those in the parietal and occipital cortex implicated in visuospatial processing and cognition.
