The ENIGMA MDD Working group is an international collaboration currently including 40 research samples from 14 different countries worldwide, including brain scans from around >5,000 MDD patients and >9,000 controls. The primary aim of our ENIGMA-MDD Working Group is to identify imaging markers that robustly discriminate MDD patients from healthy controls across many different samples using carefully a priori planned, standardized image processing and statistical analysis protocols. The ENIGMA MDD working group is led by A/Prof Lianne Schmaal (chair) and Prof Dick Veltman (co-chair).

A list of participating groups (updated May 2020) can be found here.

We are happy to welcome new cohorts at any time!

If you would like more information and/or are interested in participating, please contact A/Prof Lianne Schmaal
