People in nursing homes who are suffering with dementia could benefit from having access to gardens on the grounds, a new study suggests.

According to UK researchers, dementia is a major public health concern worldwide, with an estimated 7.7 million new cases being identified annually. Many residents in nursing homes have dementia or dementia symptoms.

The researchers analysed 17 different studies to assess the potential benefits of outdoor spaces among people with dementia and found that gardens promote relaxation and reduce agitation among nursing home residents. They also encourage people to be more physically active.

The study also noted that gardens are a good place to meet with visitors as they sometimes stimulate memories in the person with dementia.

"There is an increasing interest in improving dementia symptoms without the use of drugs. We think that gardens could be benefitting dementia sufferers by providing them with sensory stimulation and an environment that triggers memories. They not only present an opportunity to relax in a calming setting, but also to remember skills and habits that have brought enjoyment in the past," noted the study's lead researcher, Rebecca Whear, of the University of Exeter.

The researchers acknowledged that this area needs to be investigated more and issues need to be taken into account, such as garden design and potential hazards. However, they believe that these answers should be pursued ‘to ensure that care experiences can be maximised for sufferers of dementia, their carers and families'.

Details of these findings are published in the Journal of the American Medical Directors Association.
