Effectiveness of Horticultural Therapy in People with Dementia: A Quantitative Systematic Review
Summary
The study synthesizes findings from 14 studies (4 RCTs and 10 quasi-experimental studies) involving 411 individuals with dementia, confirming that participatory horticultural therapy (e.g., planting, weeding, and floriculture) significantly improves cognitive function, reduces agitation, and enhances positive emotions and engagement. In contrast, ornamental horticultural activities (e.g., viewing gardens, looking at nature images) did not show significant improvements in agitation and emotional well-being.
Meta-analysis results suggest that horticultural therapy should be prioritized as a non-pharmacological intervention for dementia care, particularly participatory approaches that stimulate sensory and cognitive functions. The study highlights the need for more high-quality research to further validate these findings and refine clinical guidelines for integrating horticultural therapy into dementia care settings.
