The study examined trends in assisted dying and euthanasia in patients with psychiatric disorders and dementia in Belgium from 2002 to 2023, based on data from the Federal Commission for the Control and Evaluation of Euthanasia (a total of 33,592 cases).[1] Psychiatric disorders accounted for 1.27% and dementia for 0.92% of all euthanasia cases.[1] Euthanasia for psychiatric disorders showed a modest increase similar to trends in other types of euthanasia, while euthanasia for dementia increased more rapidly.[1] Trends in euthanasia for dementia and psychiatric disorders have coincided with demographic changes in the population.[1] The euthanasia rate for psychiatric disorders was initially higher among women, but the rate among men increased over time.[1] Regional differences showed a higher overall rate of euthanasia in the Dutch-speaking population, but with a faster increase in the Francophone population.[1] The study identified gender and regional disparities that were narrowing at the time of the study.
