A new study has highlighted the complex emotions and ethical dilemmas of learning your future risk of Alzheimer’s disease. Among 274 healthy research participants from the US aged 65 and over, 40% declined to receive their personal risk estimates – despite having initially expressed an interest in doing so.
These risk estimates were based on demographic data, brain imaging and blood biomarkers, offering an 82 to 84% accuracy in predicting the likelihood of developing Alzheimer’s disease within five years. By comparison, age alone can predict this risk with 79% accuracy.
