One final example is the prefrontal cortex, which is thought to play an important role in regulating behavior by suppressing impulses and emotions arising from the amygdala and other parts of the limbic system.50 — 52 In animal studies, exposure to chronic stress or glucocorticoids alters the synaptic connectivity within the prefrontal cortex, 52,53 and this may limit the ability of the prefrontal cortex to (1) suppress the impulsivity and aggression of the limbic system, and (2) execute adaptive responses (rather than maladaptive responses) to stress.54 — 56 Stress - induced changes in brain structure parallel the well - described impact of significant childhood adversity on a variety of brain functions, including the modulation of physiologic responses (hyper - responsive or chronically active stress response), learning (impaired memory), and the regulation of behavior (the ability to execute adaptive vs maladaptive responses to stress).3, 39,57

These toxic stress - induced changes in brain structure and function mediate, at least in part, the well - described relationship between adversity and altered life - course trajectories (see Fig 1).4, 6 A hyper - responsive or chronically activated stress response contributes to the inflammation and changes in immune function that are seen in those chronic, noncommunicable diseases often associated with childhood adversity, like chronic obstructive pulmonary disease (COPD), cirrhosis, type II diabetes, depression, and cardiovascular disease.4, 6 Impairments in critical SE, language, and cognitive skills contribute to the fractured social networks often associated with childhood adversity, like school failure, poverty, divorce, homelessness, violence, and limited access to healthcare.4, 19,58 — 60 Finally, behavioral allostasis, or the adoption of potentially maladaptive behaviors to deal or cope with chronic stress, begins to explain the association between childhood adversity and unhealthy lifestyles, like alcohol, tobacco, and substance abuse, promiscuity, gambling, and obesity.4, 6,61 Taken together, these 3 general classes of altered developmental outcomes (unhealthy lifestyles, fractured social networks, and changes in immune function) contribute to the development of noncommunicable diseases and encompass many of the morbidities associated epidemiologically with childhood adversity.4, 6
