The effect of a multimodal dementia prevention program involving community-dwelling elderly.

Abstract

BackgroundWith the rapid increase in the average age of society, the number of people with dementia has increased in Japan. Thus, the need to prevent dementia is greater, and prevention programs have been implemented throughout Japan. This study aims to evaluate both the short‐term and the long‐term effects of a dementia prevention program on physical and cognitive function in community‐dwelling elderly.MethodsCognitive and physical assessments were carried out at baseline for a sample including 57 elderly participants. The participants underwent an intensive training program lasting for 2 h per week for 10 days. After the last period of training, the assessment performed was reapplied. The outcome measures used to establish effectiveness were a Mini‐Mental State Examination, Five Cognitive Tests, a Cognitive Function Instrument, a Timed Up & Go Test, a grip strength evaluation, a Geriatric Depression Scale, an EQ‐5D and a Physical Activity Scale for the Elderly. Participants were then divided randomly into two groups: a booster group and a non‐booster group. The booster group received booster training every 3 months after the intensive training period, whereas the non‐booster group did not. Both groups were monitored every 6 months for approximately two and a half years after baseline assessment.ResultsThe Mini‐Mental State Examination, the subtests of the Five Cognitive Tests (attention, memory, language and reasoning) and the Timed Up & Go Test revealed a significant improvement after intensive training. For most of the outcome measures, the booster training showed no additional significant improvements.ConclusionsIn this study, intensive training had a short‐term positive effect. Although the effect of the booster training was not clear, the functions of the elderly participants were found to be maintained during a follow‐up assessment. The study findings recommend conducting intensive training for the community‐dwelling elderly without follow‐up training.
