OBJECTIVE: Alzheimer's disease (AD) care has been reshaped by the integration of fluid biomarkers. This review addressed the question "What are the ethical considerations of fluid biomarker use in eligibility assessments for treatment in AD and mild cognitive impairment?"
METHODS: A rapid review following established guidelines was performed. Relevant data were identified and organised within the four pillars of biomedical ethics. Results were reported in line with the PRISMA checklist.
RESULTS: Searches identified 10,611 records; 34 were included following screening. Narrative synthesis suggests there are a greater number of ethical risks over benefits within the current clinical context. However, interpretation is subjective and empirical data is lacking.
CONCLUSIONS: Multiple ethical concerns surround the use of fluid biomarkers in AD treatment decisions, and there is limited empirical evidence to substantiate claims about benefits and harms. Uncertainty in biomarker performance, particularly in underrepresented groups, raises risks to non-maleficence, autonomy, and justice and complicates clinical decision making.
