@AMPADDataReleaseUpdates We are changing the AMP-AD Knowledge Portal data access requirements to streamline the access process and keep in compliance with evolving regulations. Data from some studies that previously were available without the requirement of a Data Use Certificate (DUC) now will require it. Data for which there is no known risk of re-identification will remain available for Synapse users without DUC submission. To ensure your access is not interrupted, we encourage you to make sure you have an active [AMP-AD Knowledge Portal DUC](https://www.synapse.org/#!AccessRequirements:ID=syn13894145&TYPE=ENTITY) on file. No changes will be made to the ROSMAP data access, which is covered under a separate [ROSMAP DUC](https://www.synapse.org/#!AccessRequirements:ID=syn3219045&TYPE=ENTITY).
