In Sweden dementia is the fourth most common disease and in the world the numbers are expected to be twice as high in the year of 2030. Therefore it is im-portant to find alternative, cost-effective forms of treatments that are effective on this specific group. The aim of the study was to examine the health effects of ani-mals in the care of individuals diagnosed with Alzheimer’s disease or other re-lated diseases. A literature review including ten articles in the result was made. Animals in Alzheimer’s and dementia care indicate positive effects such as de-creased agitation and anxiety, increased verbalizations, increase in tactile contact and seeking for contact and improved nutrition among these individuals. The con-clusion is that animals can serve as an effective complement in the care of indi-viduals with Alzheimer’s disease or other related diseases.
