Implementing mindfulness-based stress reduction to interrupt continuous HPA-axis activation and support hippocampal recovery

What effect does chronic HPA-axis activation have on the brain in anxiety disorders?

It impairs hippocampal function, affecting memory and reinforcing stress responses through heightened amygdala reactivity
