Research Abstract |
By using visual evoked potentials, event-related potentials (ERPs) and functional magnetic resonance imaging (fMRI) with multimodal visual stimuli, we investigated the difference in the brain response among healthy young adults, old adults and patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD). As results, we found that ERP and fMRI responses for motion stimuli were significantly decreased in patients with MCI and AD compared to healthy old adults. Therefore, ERP and fMRI responses for motion stimuli are the most useful for early detection of MCI non-invasively.
