Deposits of beta amyloid protein in the brain are a common sign of Alzheimer’s disease. AMYPAD will study the value of using positron emission tomography (PET) imaging to scan people’s brains for beta amyloid deposits. AMYPAD will carry out beta amyloid PET imaging on an unprecedented number of people who are suspected to be in the early stages of Alzheimer’s disease. The goal is to determine the clinical added value of PET imaging in diagnosis and patient monitoring, and to develop data to establish its usefulness in clinical trials. AMYPAD will work closely with IMI’s EPAD project, which is working to increase our understanding of the early stages of dementia and creating a platform to test treatments designed to prevent dementia.
