Title: Effectiveness of a Brain-Computer Interface Based System for Cognitive Enhancement in the Normal Elderly
Brief Summary: The primary objective is to examine the efficacy of 8-weeks of a locally developed brain-computer interface based system (BrainpalTM)intervention for improving attention and memory in normal elderly. We hypothesize that elderly who have completed the training program will have significant improvement in their attention and memory compared to the controls, based on the Repeatable Battery for the Assessment of Neuropsychological Status.
