This article summarizes the impact of inter-generational cooperation on the quality of life of elderly Alzheimer’s sufferers. The study is a continuing, two-year intervention and reports the results of the first year. It consists of an intervention and a control group of eight and six sufferers, respectively, who have been diagnosed with Alzheimer's disease. Both groups attend day care services. The intervention group participates in the inter-generational program with children, while the control group does not. On the Philadelphia Geriatric Center Affect Rating Scale, three items have been proved statistically significant. Pleasure, Interest, and Contentment have increased with inter-generational cooperation. The magnitude of the change was not so remarkable as to influence QOL-AD at home. However, the present results may imply a reduction on the burden of the day care service staff and family carers. Another advantage may be in the educating of the children’s parents, whose understanding of dementia was poor.
