The Effect of Computer-Based Cognitive Training Program On Cognition

Abstract

Background: Effective non-pharmacological cognitive program to prevent Alzheimer’s dementia or slow its progression are an urgent international priority. The effect of computer-based cognitive training program has not been demonstrated yet in dementia. The purpose of this study is to know whe ther the computer-based cognitive training improved cognitive abilities in patients with mild cognitive disorder and early stage of dementia. Methods: Totally 20 participants (14 with MCI and 6 with mild Alzhie mer dementia) participated in this study. To test the effectiveness of computer-based cognitive training programs to cognition, all patient were randomly allocated to an intervention group (n= 10) or a control group (n= 10) An intervention group received regularly computer-based cognitive training totally 20 times for 10 weeks. Neuropsychological examinations were conducted before and after this period. Results: After 10 weeks, intervention group showed a significant change in language of K-MMSE compared with baseline cognitive examinations. Also, there was improvement in attention (backward digit span), calculation, memory, and frontal function for the intervention group as compared with controls. Patients with mild cognitive disorder showed marked improvements in language and visuospatial capacity, while patients with dementia showed no or slight improvement in these fields. Conclusions: Computer-based cognitive training program might have beneficial effect on general cognitive function in both mild cognitive disorder and dementia. Especially, conspicuous effectiveness showed in patients with mild cognitive disorder. Received: November 14, 2013 Revision received: December 11, 2013 Accepted: December 11, 2013
