Abstract

In Canada, there is interest in expanding medical assistance in dying (MAID) to include advance requests (AR) for people living with dementia (PLWD). However, operationalizing the intolerable suffering criterion for MAID in ARs for PLWD is complicated by the Canadian legal context—in which MAID is understood as a medical intervention and suffering is conceptualized as subjective—and the degenerative nature of dementia. ARs that express a wish to receive MAID when the PLWD develops pre-specified impairments are problematic because people are unlikely to accurately predict the conditions that will cause intolerable suffering. ARs that express a wish to receive MAID when the PLWD exhibits pre-specified behaviors that likely represent suffering are problematic because they are inconsistent with the subjective conceptualization of suffering. Further research is required to determine whether adopting an objective conceptualization of suffering is justified in these cases and, if so, how to reliably identify intolerable suffering in PLWD.
