In euthanasia and/or assisted suicide (EAS) of persons with dementia, the controversy has mostly focused on decisionally incapable persons with very advanced dementia for whom the procedure must be based on a written advance euthanasia directive. This focus on advance euthanasia directive-based EAS has been accompanied by scant attention to the issue of decision-making capacity assessment of persons with dementia who are being evaluated for concurrent request EAS. We build on a previous analysis of concurrent request EAS cases from the Netherlands, which showed that many such cases involve persons with significant cognitive impairment. We use illustrative cases to describe the difficulty of determining decisional capacity in persons whose stage of dementia falls between severely impaired and mildly impaired. We show that the Dutch practice of capacity assessment in such dementia cases is difficult to reconcile with the widely accepted functional model of capacity—a model explicitly endorsed by the Dutch euthanasia review committees. We discuss why such deviations from the standard functional model might be occurring, as well as their ethical implications for dementia EAS policy and practice.
