A key to the success of AETIONOMY will be the quality and quantity of data from patients with Alzheimer’s and Parkinson’s disease that we can access. AETIONOMY is being built on the datasets from the current collaborators and the publically available datasets. However we know that whilst this is a good starting point there are a lot of high quality datasets that we cannot access. The aim of AETIONOMY is to develop a comprehensive map of pathophysiological processes causing Alzheimer’s Disease and Parkinson’s Disease and these maps will be publically available to everyone. These maps will form the basis of the new disease classification which we will be encouraging everyone to validate. If you have datasets and are willing to collaborate then we would really like you to contact the AETIONOMY project office as we want this project to be as comprehensive as possible and a foundation for Alzheimer’s and Parkinson’s disease research and clinical practice for the biomedical community.
