Many AI and ML studies suggest 'unrealistic' 90+% accuracies, all without proper out-of-sample replications. This was our main driver to release the open-access TDBRAIN database incl more then 1200 EEGs and rich phenotype data. Glad to see a first diagnostic replication with a realistic accuracy.

Some time ago we released the open-access TDBRAIN dataset with more than 1200 EEG's and rich phenotype data (ADHD, MDD and OCD), and include 'blinded' cases for out-of-sample validation. The results show it is not easy to get a succesful out-of-sample replication, but glad to see some groups do!

This research replicates our prior findings on the efficacy of OFC TMS as a viable option for patients who do not respond to DLPFC TMS. The results have now been validated in a third extensive clinical sample conducted at Salience TMS.
Time to integrate OFC TMS into the updated guidelines!
