Parents living with dementia sometimes do not recognize their adult child caregivers, who may then perceive they are forgotten. Yet, research on the experience of being unrecognized and perceived as forgotten by a parent with dementia is scarce. Object relations theory suggests healthy development of a child's sense of self during early development is linked to being held in mind by a primary caretaker. Thus, it is unclear how being unrecognized and perceived as forgotten by parents living with dementia impacts adult children's identities. To investigate this phenomenon, this qualitative study explored adult child caregivers' experiences of not being recognized in the context of a parent's dementia. The aims were to (1) develop an in-depth understanding of what it means for adult children to perceive they were unrecognized and/or forgotten by their parents with dementia and (2) gain insight on the effects of being unrecognized and perceived as forgotten on adult children's identities.

Interpretative Phenomenological Analysis was conducted to analyze data collected via semi-structured in-depth interviews. Findings revealed participants experienced intense emotional pain from perceptions of being forgotten resulting in injuries to their identity and sense of self. Four superordinate themes were identified:
