Outline of Final Research Achievements

The efficacy of a multimodal non-pharmacological intervention program (an intervention combining exercise, cognitive tasks, and daily living activity training) developed by the applicants to maintain and improve cognitive function (gloval cognitive function, disorientation, memory, and constructitonal ability) in older people with dementia in nursing home was tested using a single case design. It was first tested in a preliminary study, followed by a randomized, controlled, two-arm study at a multicenter site. In the single-case design, one subject showed improvement in cognitive function, and two subjects showed maintenance, confirming that the intervention was realistically feasible. The randomized controlled trial suggested the possibility of a sustained effect on constructitonal ability at post-intervention follow-up. It also confirmed the improvement of BPSD and the possibility of a sustained effect.

Academic Significance and Societal Importance of the Research Achievements

代表者らが作成したマルチモーダル非薬物的介入は，これまでの介入と比較してより簡易的に実施でき，全般的認知機能，見当識，記憶，構成能力の維持・改善にもより効率的かつ効果的に働きかける可能性がある．マルチモーダル非薬物的介入の実効性が明らかになることで，施設入所認知症高齢者の認知機能維持・改善に対して，効果的な介入戦略につながる新しい知見をもたらすことが期待される．
このことは，施設入所認知症高齢者のADL低下やBPSDの誘発，QOL低下，認知症高齢者の家族の介護負担，更には医療費増大への対策にも繋がることが期待される．
