7 +== **How to Use External Databases in Neurodiagnoses** ==
24 24  
25 -== Overview ==
9 +To enhance the accuracy of our diagnostic models, Neurodiagnoses integrates data from multiple biomedical and neurological research databases. If you are a researcher, follow these steps to access, prepare, and integrate data into the Neurodiagnoses framework.
26 26  
11 +=== **Potential Data Sources** ===
27 27  
28 -Neurodiagnoses integrates clinical data via the **EBRAINS Medical Informatics Platform (MIP)**. MIP federates decentralized clinical data, allowing Neurodiagnoses to securely access and process sensitive information for AI-based diagnostics.
13 +Neurodiagnoses maintains an updated list of potential biomedical databases relevant to neurodegenerative diseases.
