A presentation outlining Alzheimer’s disease (AD) and its mechanisms. AD is caused by a build-up of beta-amyloid proteins that initially form in the gut. Current diagnoses use neuroimaging and behavioral assessments, which are inefficient. We propose Amylotect: a tool that uses aptamers to detect beta-amyloid in stool samples. It is a cheap and effective way to diagnose Alzheimer’s, and has the capability of working before symptoms even start.
