- Dog Interaction May Provide Help for People with Dementia - New research from the University of Maryland suggests that structured interaction with dogs could be an effective approach for preserving and even enhancing the mental health and physical function of people with dementia. The study involved 40 elderly adults with dementia residing in assisted-living facilities and found a reduction in depression following a pet-assisted living programme involving regular interaction with a dog. The study also indicated a trend for improved physical function as a result of the pet-assisted living programme. Participants in this study had two, 60-90 minute sessions a week for three months in which they were encouraged to interact with the visiting dog. A control group was encouraged to reminisce about their experiences with researchers and other residents in a way that involved both social skills and small motor skills.
