Summary

This systematic review and meta-analysis investigates the psychological health benefits of horticultural therapy in patients with dementia, addressing concerns about the increasing global prevalence of dementia and the importance of non-pharmacological interventions. The methodology included a comprehensive search of databases identifying relevant studies that examined the impact of gardening activities, green care farms, green spaces, and therapeutic horticulture on agitation, cognitive functioning, activity engagement time, and idle time. The review adhered to PRISMA guidelines and included randomized clinical trials and prospective, retrospective, or longitudinal studies written in English.

The meta-analysis of eight studies (out of 23 reviewed) revealed that horticultural therapy lowered agitation scores (as measured by the CMAI), increased activity engagement time by 45.10%, and decreased inactivity time by 29.36%. The authors conclude that horticultural therapy offers valuable psychological health benefits for individuals with dementia, particularly in alleviating agitation and promoting engagement in activities.
