title: The changing face of personhood at the end of life: The ring theory of personhood.
abstract: OBJECTIVE
  The manner in which personhood or "what makes you who you are" is conceived is key to the provision of patient-centered care and maintenance of the dignity and quality of life of terminally ill patients. However, there is little agreement on how this pivotal concept ought to be defined. Some have argued in favor of an innate concept of personhood, while others see an individual as a reflection of their familial identity or their conscious function, and all share a common position that personhood is unchanging, and hinges upon the central theme of their respective concepts. The present paper aims to explore a more clinically influenced perspective of personhood.
  
  
  METHODS
  We report the case of a 42-year-old Malay Singaporean who had been a caregiver for her husband throughout his cancer and then became a cancer patient herself after his passing. This case explores her changing and multifaceted conceptions of personhood throughout her life and illness, and discussions about end-of-life care.
  
  
  RESULTS
  The patient reports a concept of personhood that encompasses the innate, individual, relational, and societal aspects, which are interlinked and vary in terms of depth and conviction according to the various times in her life and illness.
  
  
  CONCLUSIONS
  Our findings support the ring theory of personhood, which provides a clinically supported model of the conception of personhood that is context dependent and encompasses the four abovementioned aspects.
