How Nature Helps

There is something innate about our connection to nature. A study published in the American Journal of Alzheimer’s Disease & Other Dementias, shows that long-suffering dementia and Alzheimer’s patients are known to have decreased symptoms following time in gardens or being exposed to horticultural therapy.

Role of the Landscape Architect

Landscape architects design therapeutic gardens for use in nursing homes, which are not only known to decrease the symptoms of the patients suffering from neurological disorders like dementia and Alzheimer’s, but also decrease the stress and anxiety of the care-takers and nurses in these facilities. Taking care to address the needs of the aged and patients suffering from these disorders, landscape architects design gardens with paved paths for ease of walking, ample places to sit, raised planting beds to be enjoyed by people in wheel chairs and ample opportunity for people to be engaged with via the senses smell and touch, as well as sight.
