\nMersul pe jos protejeaz\u0103 \u00eempotriva demen\u0163ei prin mecanisme cerebrale concrete, nu doar prin beneficiile generale ale mi\u015fc\u0103rii fizice.<\/p>\n
\nOamenii de \u015ftiin\u0163\u0103 de la Universitatea Catolic\u0103 Australian\u0103 au cartografiat creierul a peste 500 de adul\u0163i cu v\u00e2rste \u00eentre 70 \u015fi 90 de ani din Sydney, timp de \u015fase ani. Concluzia este clar\u0103: cei care locuiau \u00een zone urbane dense \u015fi pietonale aveau cozi hipocampale mai mari, conform Daily Mail.<\/p>\n
\nHipocampul este structura cerebral\u0103 implicat\u0103 \u00een \u00eenv\u0103\u0163are \u015fi memorie. Partea posterioar\u0103 a hipocampului, \u00een special, are un rol esen\u0163ial \u00een memoria spa\u0163ial\u0103 \u015fi naviga\u0163ie. Mic\u015forarea rapid\u0103 a acestei zone este asociat\u0103 direct cu boala Alzheimer, cea mai frecvent\u0103 form\u0103 de demen\u0163\u0103.<\/p>\n
\nProfesorul Govinda Poudel, autorul principal al studiului, explic\u0103 mecanismul din spatele descoperirii. Traversarea unei intersec\u0163ii aglomerate nu este o ac\u0163iune simpl\u0103. Ea implic\u0103 o secven\u0163\u0103 cognitiv\u0103 complex\u0103: oprire, observare vizual\u0103, procesare auditiv\u0103 \u015fi decizie rapid\u0103.<\/p>\n
\n\u201eCu c\u00e2t un adult \u00een v\u00e2rst\u0103 \u00ee\u015fi exerseaz\u0103 mai mult memoria \u015fi abilit\u0103\u0163ile spa\u0163iale, cu at\u00e2t creierul s\u0103u devine mai s\u0103n\u0103tos \u015fi mai protejat”, a declarat profesorul Poudel. Locuitorii ora\u015felor pietonale repet\u0103 aceste secven\u0163e cognitive zilnic, f\u0103r\u0103 s\u0103 con\u015ftientizeze beneficiul pe termen lung.<\/p>\n
\nStudiul se bazeaz\u0103 \u015fi pe cercet\u0103ri anterioare care ar\u0103tau c\u0103 \u015foferii de taxi, care lucrau \u00eenainte de apari\u0163ia h\u0103r\u0163ilor digitale, aveau o inciden\u0163\u0103 mai mic\u0103 a bolii Alzheimer. Navigarea mental\u0103 a ora\u015fului le-a consolidat structurile cerebrale implicate \u00een memorie.<\/p>\n
\nProfesoara Ester Cerin, coautoare a studiului \u015fi specialist\u0103 \u00een \u015ftiin\u0163e comportamentale, subliniaz\u0103 c\u0103 descoperirile dep\u0103\u015fesc sfera individual\u0103. \u201eCartierele complexe \u015fi interconectate nu doar \u00eencurajeaz\u0103 mersul pe jos, ci sus\u0163in s\u0103n\u0103tatea creierului pe tot parcursul vie\u0163ii”, a explicat aceasta.<\/p>\n
\nCercet\u0103torii propun ca planificarea urban\u0103 s\u0103 devin\u0103 un instrument de s\u0103n\u0103tate public\u0103. Crearea de cartiere accesibile pietonilor \u015fi stimulante cognitiv ar putea \u00eent\u00e2rzia apari\u0163ia demen\u0163ei la nivel de popula\u0163ie.<\/p>\n
\nContextul este unul alarmant. \u00cen prezent, aproximativ 900.000 de persoane sufer\u0103 de demen\u0163\u0103 \u00een Regatul Unit. Cifra este estimat\u0103 s\u0103 dep\u0103\u015feasc\u0103 1,6 milioane p\u00e2n\u0103 \u00een 2040. Demen\u0163a este principala cauz\u0103 de deces \u00een Marea Britanie, cu peste 74.000 de decese anual.<\/p>\n
\nExper\u0163i de renume mondial au avertizat recent c\u0103 milioane de cazuri ar putea fi prevenite prin schimb\u0103ri simple ale stilului de via\u0163\u0103 \u015fi prin politici publice coordonate. Un raport publicat \u00een ianuarie a identificat 56 de recomand\u0103ri bazate pe dovezi, de la combaterea pierderii auzului p\u00e2n\u0103 la reducerea izol\u0103rii sociale.<\/p>\n
