Quiz on blood biomarkers of Alzheimer’s dementia

New blood tests could potentially detect Alzheimer’s dementia at an early stage – but how reliable are they? What does it mean to be at risk? And what ethical challenges arise? This quiz was created on the occasion of the Night of Knowledge 2025 in Göttingen to encourage people to engage with the topic and further discussion.
