Dementia Care Mapping (DCM) is a care method designed to improve the quality of life for individuals with intellectual disabilities (VB) and dementia. It helps caregivers understand and respond to the needs of clients with VB and dementia, enhancing the quality of care and reducing the burden on caregivers. The article discusses the challenges of identifying dementia in people with VB and the importance of using structured care methods. Research by Alliade's PWO department revealed that there are 28 care methods in the Netherlands that meet specific criteria for being effective in supporting people with VB. Three of these are specifically aimed at dementia in people with VB: Belevingsgerichte zorg, Dementia Care Mapping (DCM), and Urlings en Van der Linden. DCM is considered the most effective, based on qualitative research showing positive effects on caregivers' understanding of client behavior and support methods. Quantitative research showed mixed results, with no significant effects on work satisfaction or quality of life. DCM is based on person-centered care, emphasizing the client's overall well-being and individual values. It involves a trained observer (mapper) who observes clients for four to six hours, noting behaviors and emotional states. The mapper records two codes every five minutes: a behavior code (GCC) and a code for mood and engagement (SB). These codes help assess the client's emotional state and engagement level. DCM was originally developed for people with dementia without VB but has been found to be effective for those with VB and dementia. It emphasizes the importance of respecting the emotional needs of individuals with dementia, as their cognitive abilities may decline, but their emotional sensitivity remains. DCM aims to systematically monitor the client's condition and provide appropriate support to maintain their self-confidence and sense of security.Dementia Care Mapping (DCM) is a care method designed to improve the quality of life for individuals with intellectual disabilities (VB) and dementia.
