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
For example, studies of medical students facing examinations and kindergarten children beginning school reveal
changes in
immune functioning
potentially prognostic for adverse health outcomes, including
changes in numbers of total t - lymphocytes, natural killer cell cytotoxicity, and lymphocyte responsivity to mitogenic stimulation (e.g., 8, 9).
