Interventions Used to Increase Participation Among Older Adults Experiencing Mild Cognitive Decline: A Systematic Review

Occupational therapy-delivered interventions are effective for older adults with mild cognitive decline, although further evidence is needed for greater confidence. Plain-Language Summary: Mild cognitive decline is a deterioration in a person's thinking and memory that does not have a medical cause. Although it is more likely to affect older adults, it is not considered part of normal aging. However, it can occasionally progress to more severe forms of dementia. Staying active and independent is known to preserve quality of life among older adults with mild cognitive decline. Occupational therapists play a crucial role in supporting older adults in maintaining their independence and quality of life. This study examined different interventions used by occupational therapists to minimize the impact of mild cognitive decline. The authors found that a range of occupational therapy interventions can effectively enhance participation in meaningful activities; these benefits were observed immediately after treatment and up to 6 months later. However, more evidence is needed to understand the full impact of occupational therapy in this context.
