Mental Exercises for Cognitive Function: Clinical Evidence
Kawashima, Ryuta The Korean Society for Preventive Medicine 2013 Journal of Preventive Medicine and Public Health Vol.46 No.suppl
The purpose of this study was to examine the beneficial effects of a new cognitive intervention program designed for the care and prevention of dementia, namely Learning Therapy. The training program used systematized basic problems in arithmetic and Japanese language as training tasks. In study 1, 16 individuals in the experimental group and 16 in the control group were recruited from a nursing home. In both groups, all individuals were clinically diagnosed with senile dementia of the Alzheimer type. In study 2, we performed a single-blind, randomized controlled trial in our cognitive intervention program of 124 community-dwelling seniors. In both studies, the daily training program using reading and arithmetic tasks was carried out approximately 5 days a week, for 15 to 20 minutes a day in the intervention groups. Neuropsychological measures were determined simultaneously in the groups both prior to and after six months of the intervention. The results of our investigations indicate that our cognitive intervention using reading and arithmetic problems demonstrated a transfer effect and they provide convincing evidence that cognitive training maintains and improves the cognitive functions of dementia patients and healthy seniors.

Processing of Anomalous Sentences in Japanese: An fMRI Study

Most previous neuroimaging studies of anomalous sentence processing have used Indo-European languages to separately identify syntactic and semantic processing mechanisms. However, typologically distant languages such as Japanese use different sources of information in grammatical role assignments. Thus, we expected that the activation pattern during processing of anomalous sentences in Japanese would be at least partially different from that in other languages reported in previous studies. We used functional magnetic resonance imaging (fMRI) to measure activation during judgments of the correctness of normal and anomalous sentences in native Japanese speakers. We presented simple Japanese sentences as auditory stimuli. Significant activation was found in the left middle and inferior frontal regions (pars orbitaris and pars triangularis) and the superior parietal lobule during processing of sentences with semantic violations. On the other hand, no preferential activation was found, except for the left anterior part of the superior temporal gyrus, during the processing of sentences with syntactic violations. Additionally, activation in the left inferior frontal gyrus, which has been reported in previous studies using Indo-European languages, was not found in our study. The results support our assumption that the left inferior frontal gyrus plays a minor role in syntactic processing of simple Japanese sentences.
