chronic disease

(Editor’s note: Path­ways respon­si­ble for high­er-order think­ing in the pre­frontal cor­tex (PFC), or exec­u­tive cen­ter of the brain, remain vul­ner­a­ble through­out life—during crit­i­cal ear­ly-life devel­op­men­tal win­dows, when the PFC ful­ly matures in the ear­ly 20s, and final­ly from declines asso­ci­at­ed with old age. At all ages, phys­i­cal activ­i­ty and PFC-nav­i­gat­ed social con­nec­tions are essen­tial com­po­nents to main­tain­ing brain health. The Expe­ri­ence Corps, a com­mu­ni­ty-based social-engage­ment pro­gram, part­ners seniors with local schools to pro­mote pur­pose-dri­ven involve­ment. Par­tic­i­pat­ing seniors have exhib­it­ed imme­di­ate short-term gains in brain regions vul­ner­a­ble to aging, such as the PFC, indi­cat­ing that peo­ple with the most to lose have the most to gain from envi­ron­men­tal enrichment.)

Over the last decade, sci­en­tists made two key dis­cov­er­ies that reframed our under­stand­ing of the adult brain’s poten­tial to ben­e­fit from life­long envi­ron­men­tal enrich­ment. First, they learned that the adult brain remains plas­tic; it can gen­er­ate new neu­rons in response to phys­i­cal activ­i­ty and new expe­ri­ences. Sec­ond, they con­firmed the impor­tance of social con­nect­ed­ness to late-life cog­ni­tive, psy­cho­log­i­cal, and phys­i­cal health. The inte­gra­tion of these find­ings with our under­stand­ing of indi­vid­u­als’ devel­op­men­tal needs through­out life under­scores the impor­tance of the “social brain.” The pre­frontal cor­tex (PFC) is par­tic­u­lar­ly inte­gral to nav­i­gat­ing com­plex social behav­iors and hier­ar­chies over the life course.
