The objective of this study was to examine the benefits of Snoezelen room for older people living in nursing homes. Participants were 84 people with dementia from Barcelona (Spain) that were randomly assigned to Snoezelen or reminiscence sessions. Bi-weekly sessions were held over a period of 12 weeks. Participants in the Snoezelen group displayed significant improvements in depression and anxiety and a greater degree of relaxation. Participants with slight dementia were also more likely to display more alertness and offer constructive answers. Snoezelen room could be implemented in a range of dementia’s stages, stressing its implications for slight dementia profile.
