Early-life stress can disrupt maturation of brain’s reward circuits
Depends on what particular "stress and adversity" from early life/ ELA from article. From what we have learnt from Spirituality and all of the wise philosophers, that sounds contradictory. Most of the teachings of philosophy point to adversity and stress as events from which we can learn from and become more stronger mentally. It's possible that always being in this state of stress can morph your worldview to always be broken, and perhaps that is what's being referenced and reflected here.
