Objective : The purpose of this study is to investigate the effects of Snoezelen on the BPSD and EEG Activity of elderly persons with dementia. Methods : A single-subject A-B-A’ experimental design was used to determine the effects of Snoezelen therapy. The participants of the study were three elderly participants with Behavioural and Psychological Symptoms of Dementia (BPSD). They participated in nine 20-30 minute sessions over a 6-week period. The ratings of the BPSD recorded by video were taken before, during, and after the intervention phase. EEG measurements and brain mapping consisting of eight channels were performed immediately before and after the treatment sessions. Results : The participants showed a decrease in the frequency of BPSD with wandering, repetitive behavior, delusions, and anxiety. The results of the EEG measurements showed increased alpha and beta waves, and a reduction of theta and gamma waves, for 2 patients. Conclusion : These findings provide evidence of the neurophysiologic aspects supporting that Snoezelen is an effective approach for the treatment of BPSD on elderly persons with dementia.
