Gardens in care homes may help dementia sufferers remember vital memories, scientists have found.
Researchers at the University of Exeter Medical School found green spaces helped care home residents relax, and reduced agitation for those with dementia.
Care home gardens were also found to aid the well-being of dementia patients and relatives, as well as stimulating memories.
Residents at 11 UK care homes were included in the research, as well as services in America, China and Europe.
Almost half of the elderly people living in residential care have dementia or dementia symptoms, a figure which increases to more than three-quarters in nursing homes.
