The impact of non-pharmacological interventions on quality of life in dementia: a review of evidence and outcomes

OpenAlex İngilizce

Dementia is a neurodegenerative disease that causes a progressive decline in cognitive function in older people, seriously affecting their quality of life. Different types of dementia, such as Alzheimer’s disease, vascular dementia and dementia with Lewy bodies, cause a significant decline in patients’ daily living skills, social interactions and general health status. In this context, the impact of dementia on individuals’ quality of life has been extensively studied. Non-pharmacological interventions have an important place in the management of dementia. Approaches such as physical activity, cognitive exercises, social interaction, healthy diet and music therapy support patients’ cognitive functions and offer potential benefits in improving quality of life. Research indicates that these interventions not only delay the cognitive decline associated with dementia but also reduce psychological symptoms like depression and anxiety, thereby enhancing emotional well-being. In particular, given the progressive nature of dementia, it is emphasised that the implementation of such interventions plays an important role in mitigating the negative effects of the disease. Evidence from recent studies underscores that the integration of these approaches into dementia care improves daily functioning and lessens caregiver burden, emphasizing the need for a comprehensive care model. Furthermore, given the economic and societal impact of dementia, it is essential to develop strategies to improve patients’ quality of life. Studies show that holistic and sustainable interventions are needed to mitigate the far-reaching effects of dementia on individuals and society.
