Effects of animal-assisted therapy as an animal-assisted intervention for dementia patients: Systemic literature review
This article provides a review of research published from 1990 to 2014 year on the effect of animal-assisted therapy as an animal-assisted intervention for dementia. Animal-assisted intervention is gaining popularity as part of therapy programs in residential aged care facilities. Humans and pet dogs respond to quiet interaction with a lowering of blood pressure and an increase in neurochemicals associated with relaxation and bonding. These effects may be of benefit in ameliorating behavioral and psychological symptoms of dementia. Current literature suggests that animal-assisted intervention may ameliorate behavioral and psychological symptoms of dementia, but the duration of the beneficial effect has not been explored. Future research employing more rigorous designs and systematically building upon a clearly defined line of inquiry is needed to advance our knowledge on the effect of animal-assisted intervention for dementia..
