Improvement of Cognitive Function after Computer-Based Cognitive Training in Early Stage of Alzheimer's Dementia

BACKGROUND AND PURPOSE: Cognitive training is known to be an effective tool in enhancing cognitive functioning. Research has also shown that playing video game improves certain aspects of visual attention and cognitive processing speed. The effect of computer-based cognitive training has not been demonstrated so far. This study therefore evaluated whether computer-based cognitive training improved the cognitive abilities in patients with early stage of Alzheimer's dementia. METHODS: Totally, 20 participants (early stage of Alzheimer's dementia) participated in this study. To test the effectiveness of computer-based cognitive training programs to cognition, all patients were randomly allocated to either an intervention group (n=10) or a control group (n=10). The intervention group regularly received 24 sessions of computer-based cognitive training, over a 12 week period. Neuropsychological examinations were conducted before and after this training period. RESULTS: After 12 weeks, the intervention group showed a significant change in language of Korean version of the Mini-Mental State Examination (K-MMSE), compared with the baseline cognitive examinations. Also, there was greater improvement in language, attention, calculation, verbal memory, and frontal function for the experimental group, as compared with controls. CONCLUSIONS: Computer-based cognitive training might have beneficial effects on the general cognitive functions in early stage of Alzheimer's dementia.

The Effect of Computer-Based Cognitive Training Program On Cognition

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 whether 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 Alzhiemer 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.
