Dementing disorders such as Alzheimer's disease have an enormous impact on the everyday life of the person affected, on his or her family members, and on the staff involved in providing daily care (Borell, 1992). Cognitive dysfunction resulting from dementing diseases, such as memory problems, interferes greatly with the performance of most activities of daily living. The field of occupational therapy has developed a variety of intervention programs addressing everyday activities for persons with dementia. A review of the relevant literature shows, however, that even if the need for such interventions is acknowledged (Porszt-Miron et al., 1988) and an outline for the intervention is described (Bryant, 1991; Rogers et al., 1987), there are few studies evaluating the efficacy and functional relevance of such interventions. Consequently, one urgent task for research is to identify and evaluate intervention strategies addressing occupational functioning among persons with dementia disorders.
