Dementia is associated with a major decrease in quality of life of clients and their caregivers and a major driver of costs in health care. Recently, evidence was found for the effectiveness and cost-effectiveness of a community-based occupational therapy (OT) intervention for older adults with dementia and their caregivers (COTiD program). This intervention resulted in significant improvements in both clients' and caregivers' daily functioning, quality of life, mood and health status. In addition, caregivers experienced an increased sense of competence.
