Review question: Can simulated presence therapy (SPT) treat problem behaviours, and improve quality of life for people with dementia?
Study characteristics: We looked for trials which compared SPT to usual care or to another treatment. Ideally, people with dementia should have been randomly allocated to one or other treatment, but we also included trials even if treatment allocation was not strictly random.
We found three trials which met our inclusion criteria. The 144 participants were all living in nursing homes. The majority were women with an average age of over 80 years and severe dementia. The way SPT was administered was different in each trial. All the trials used more than one comparison treatment, which differed between trials. The trials all attempted to measure an effect on agitated behaviours, but used different approaches.
Key findings: Because the trials were so different from each other, we were not able to pool the results. Individually, each trial reported different methods to assess the effect of SPT on behavioural problems and the results varied depending on the method used to measure the outcome.
None of the studies assessed quality of life, effect on daily activities, effects on caregivers, or how likely participants were to drop out of the study.
