Globally, dementia is one of the leading causes of disability in older adults. Despite increasing awareness of the challenges faced by people living with dementia seeking care in hospital settings, systemic shortcomings persist, hindering the delivery of effective and dignified care. Drawing on both quantitative and lived experience research, this entry explores the nuanced dynamics of ageism and dementia stigma in hospital care, shedding light on how this impacts the quality of care provided to people living with dementia and their health and well-being. By exploring the antecedents and consequences of these biases, this entry emphasizes the critical need for transformative measures in hospital care practices to combat stigma, promote inclusivity, and ensure equitable treatment for people living with dementia. A paradigm shift toward more compassionate and person-centered approaches that remove the barriers that increase disability within this population will have implications for advancing both research and practice in dementia care within hospital settings.
