Decision-making, Ethical Consent, and Interactive Dialogue in Ongoing Neurocognitive Decline - DECISION

We're still translating this one. In a couple of days, you'll see what this trial actually tests — and whether it matters for APOE4 carriers like you. For now, here's the sponsor's own description:

DECISION Study - Summary Title: Decision-making, Ethical Consent, and Interactive Dialogue in Ongoing Neurocognitive Decline The DECISION study aims to develop and validate a simplified yet robust tool for assessing the capacity to give informed consent in patients with Alzheimer's disease and related dementias. Existing tools like the MacCAT-T are too complex for routine use, so this project focuses on creating a user-friendly, valid alternative that addresses language, attention, insight, judgment, and decision-making. The study uses a multi-phase approach including: * Development and validation of a new consent capacity test battery * Correlation of cognitive decline with brain changes and biomarkers (MRI, OCT, plasma markers) * Ethical, legal, and co-design perspectives to ensure practical and responsible application The target group includes 100-150 participants from earlier dementia studies. The ultimate goal is to establish a clinically usable, legally sound instrument for assessing consent capacity in individuals with cognitive impairments.
