This figure is expected to triple to 130 million in 2050.~In France, the number of dementia cases is estimated at 754,000 and could reach 1,813,000 in 2050.~In a recent literature review, researchers highlighted the many benefits of horticultural therapy and garden environments for people with Alzheimer's or cognitive disorders.
