The purpose of this study was to examine the beneficial effects on cognitive function by a cognitive intervention program designed for dementia care called Learning Therapy in Japan and SAIDO Learning in the United States (hereinafter "SAIDO Learning," as appropriate). SAIDO Learning is a working memory training program that uses systematized basic problems in arithmetic and language, including reading aloud, as well as writing.
DESIGN, SETTING, PARTICIPANTS, AND INTERVENTION: Twenty-three nursing home residents with dementia were assigned as an intervention group, and another 24 people with dementia at another nursing home were assigned as a control group. Both nursing homes were operated by the same organization, and residents of both nursing homes received essentially the same nursing care. Thirteen and 6 subjects of the intervention and control groups, respectively, were clinically diagnosed as Alzheimer disease (AD).
After the 6-month intervention, the participants with AD of the intervention group showed statistically significant improvement in cognitive function, as measured by the Mini-Mental State Examination (MMSE) compared with the control participants. In addition, post hoc analysis revealed that the Frontal Assessment Battery at Bedside (FAB) scores of the intervention group tended to improve after 6-month intervention. Based on MDS scores, improvements in total mood severity scores also were observed, but only in the intervention group of the participants with AD.
These results suggest that SAIDO Learning is an effective cognitive intervention and is useful for dementia care. An additional outcome of this intervention, which has not yet been evaluated in detail, appears to be that it promotes greater positive engagement of a diversity of nursing home staff in the residents' individual progress and care needs.
本研究旨在探讨日本认知干预计划（称为学习疗法）和美国的 SAIDO 学习（以下适当情况下称为“SAIDO 学习”）对认知功能的有益影响。SAIDO 学习是一种工作记忆训练计划，使用系统的算术和语言基本问题，包括朗读、写作。
设计、环境、参与者和干预：23 名患有痴呆症的养老院居民被分配为干预组，另一家养老院的 24 名患有痴呆症的居民被分配为对照组。这两个养老院都是由同一个组织运营的，两个养老院的居民接受的护理基本相同。干预组和对照组的 13 名和 6 名受试者分别被临床诊断为阿尔茨海默病（AD）。
经过 6 个月的干预，干预组的 AD 患者在认知功能方面，通过简易精神状态检查（MMSE）与对照组相比，有统计学意义的改善。此外，事后分析显示，干预组的床边额叶评估量表（FAB）评分在 6 个月干预后有改善的趋势。根据 MDS 评分，总情绪严重程度评分也有所改善，但仅在 AD 患者的干预组中。
这些结果表明，SAIDO 学习是一种有效的认知干预方法，对痴呆症护理有用。这种干预的另一个结果，尚未详细评估，似乎是它促进了更多不同的养老院工作人员积极参与居民的个人进步和护理需求。
