This shift implies that many patients did not receive appropriate care for their condition, potentially leading to long-term quality of life loss.
A new study has identified two distinct brain networks associated with risk and resilience in depression. The salience network is linked to increased depression symptoms, while the default mode network is linked to decreased depression symptoms. These findings may lead to new treatments for depression using neuromodulation therapies.
