The concept of person-centeredness has become in many instances the standard of health care that humanises services and ensures that the patient/client is at the centre of care delivery. Rejecting a purely biomedical explanation of dementia that led to a loss of self, personhood in dementia could be maintained through social interaction and communication. In this article, we use the insights of queer theory to contribute to our current understanding of the care of those with dementia. We critically discuss the concepts of person and personhood that have become the cornerstone values of person-centred care for persons with dementia (PWD). Some critics, using queer theory as a theoretical approach, contend that person-centred care often (unwittingly) reproduces heteronormative roles in trying to sustain life histories. In doing so, they argue, regendering of PWD is sometimes enforced by care providers who try to safeguard this biographical continuity. Cultural theorist Linn Sandberg also mentions that other axes of domination such as race and class are not conceptualised in person-centeredness approaches, and neither are power asymmetries. Thus, in our article, we revisit the concept of person-centred care as a first step in proposing another way to think about ‘beings with dementia’ (to avoid the term person). Believing that queer theorists have fallen short in questioning the idea of person or personhood as such, we will build on and broaden Sandberg's critique by demonstrating that queer and crip theory can be understood as a fundamental critique of the (Western) subject and processes of subjectivation. We argue that dementia can be conceptualised as a radical break not only with gendered roles and embodiments, but with many of the norms that make us recognisable subjects. Conceptualising dementia in this way turns it into what Sandberg called an ‘emancipatory space’ and not merely a pathology
