In this chapter I explore the accounts of adult children caring for a parent with dementia. Dementia is typically understood to be an umbrella term for a large number of conditions, the most common of which are Alzheimer's disease, vascular dementia and fronto-temporal dementia. These are progressive-ultimately terminal-conditions that affect memory, communication, mood and behaviour. I examine the accounts of interactions with parents with dementia that fracture and reconfigure normative familial relationships. In so doing I suggest that, in the absence of a primary spousal carer, caring for a person living with dementia can necessitate particular issues for adult children that trouble notions of how we understand familial roles, responsibilities and 'duties'. This issue impacts a significant minority of British adults. There are estimated to be 670,000 informal family carers of people living with a dementia in the UK (Alzheimer's Society 2013). The total cost of dementia to UK society is estimated to be £26.3 billion, with £11.6 billion being contributed by the work of unpaid carers (Prince et al. 2014). Unpaid care to older or disabled people provided by family member is typically understood to encompass personal care and/or practical household tasks and/or paperwork and administrative duties. A classic memorial lecture given by Elaine Brody (1985) reflecting on the state of gerontological research in the USA thirty years ago has many current resonances. Brody argued that 'parent care has become a normative but stressful experience for individuals and families'. And, moreover, she suggested that the experience of caring for a parent was not a brief or short-term concern for adult children, but rather that 'it is long-term parent care that has become a normative experience-expectable, though usually unexpected' (p.19/21 original emphasis). What is interesting and resonates today, I would suggest, is the © Peel, E. (2017) 'It has had quite a lot of reverberations through the family': Reconfiguring relationships through parent with dementia care. In R. Harding, R. Fletcher & C. Beasley (Eds.) Revaluing Care in Theory, Law and Policy: Cycles and Connections. London: Routledge. 'highlighted the ways in which stress related to having a father with dementia proliferates and affects almost every area of life, leading to very high levels of distress' (Allen et al. 2009, p. 477). Therefore, it is important to recognise that parent care in the context of dementia is not solely the preserve of middle-aged adults onwards, although numerically this is the largest group of familial carers in this context.
