Is depression contagious?
Over time, adolescents' depressive symptoms increasingly converged toward the average levels of their peers, but this convergence was not primarily because of contagion effects. The findings suggest that socialization processes can lead to both increases and decreases in adolescent depression, depending on peers' average level of depression.
These results suggest that systemic inflammation activates microglia in RVLM to induce COX-2-dependent neuroinflammation that leads to an increase in O(2)(-) production. The resultant oxidative stress in RVLM in turn mediates neurogenic hypertension.
