Mersul pe jos protejeaz\u0103 \u00eempotriva demen\u021bei prin mecanisme cerebrale concrete, nu doar prin beneficiile generale ale mi\u0219c\u0103rii fizice.<\/p>\n

Oamenii de \u0219tiin\u021b\u0103 de la Universitatea Catolic\u0103 Australian\u0103 au cartografiat creierul a peste 500 de adul\u021bi cu v\u00e2rste \u00eentre 70 \u0219i 90 de ani din Sydney, timp de \u0219ase ani. Concluzia este clar\u0103: cei care locuiau \u00een zone urbane dense \u0219i pietonale aveau cozi hipocampale mai mari, conform Daily Mail<\/a>.<\/p>\n

Hipocampul este structura cerebral\u0103 implicat\u0103 \u00een \u00eenv\u0103\u021bare \u0219i memorie. Partea posterioar\u0103 a hipocampului, \u00een special, are un rol esen\u021bial \u00een memoria spa\u021bial\u0103 \u0219i naviga\u021bie. Mic\u0219orarea rapid\u0103 a acestei zone este asociat\u0103 direct cu boala Alzheimer, cea mai frecvent\u0103 form\u0103 de demen\u021b\u0103.<\/p>\n

De ce traversatul str\u0103zii este mai complex dec\u00e2t pare<\/h2>\n

Profesorul Govinda Poudel, autorul principal al studiului, explic\u0103 mecanismul din spatele descoperirii. Traversarea unei intersec\u021bii aglomerate nu este o ac\u021biune simpl\u0103. Ea implic\u0103 o secven\u021b\u0103 cognitiv\u0103 complex\u0103: oprire, observare vizual\u0103, procesare auditiv\u0103 \u0219i decizie rapid\u0103.<\/p>\n

\u201eCu c\u00e2t un adult \u00een v\u00e2rst\u0103 \u00ee\u0219i exerseaz\u0103 mai mult memoria \u0219i abilit\u0103\u021bile spa\u021biale, cu at\u00e2t creierul s\u0103u devine mai s\u0103n\u0103tos \u0219i mai protejat\u201d, a declarat profesorul Poudel. Locuitorii ora\u0219elor pietonale repet\u0103 aceste secven\u021be cognitive zilnic, f\u0103r\u0103 s\u0103 con\u0219tientizeze beneficiul pe termen lung.<\/p>\n

Studiul se bazeaz\u0103 \u0219i pe cercet\u0103ri anterioare care ar\u0103tau c\u0103 \u0219oferii de taxi, care lucrau \u00eenainte de apari\u021bia h\u0103r\u021bilor digitale, aveau o inciden\u021b\u0103 mai mic\u0103 a bolii Alzheimer. Navigarea mental\u0103 a ora\u0219ului le-a consolidat structurile cerebrale implicate \u00een memorie.<\/p>\n

Ora\u0219ele pietonale, strategie de prevenire a demen\u021bei<\/h2>\n

Profesoara Ester Cerin, coautoare a studiului \u0219i specialist\u0103 \u00een \u0219tiin\u021be comportamentale, subliniaz\u0103 c\u0103 descoperirile dep\u0103\u0219esc sfera individual\u0103. \u201eCartierele complexe \u0219i interconectate nu doar \u00eencurajeaz\u0103 mersul pe jos, ci sus\u021bin s\u0103n\u0103tatea creierului pe tot parcursul vie\u021bii\u201d, a explicat aceasta.<\/p>\n

Cercet\u0103torii propun ca planificarea urban\u0103 s\u0103 devin\u0103 un instrument de s\u0103n\u0103tate public\u0103. Crearea de cartiere accesibile pietonilor \u0219i stimulante cognitiv ar putea \u00eent\u00e2rzia apari\u021bia demen\u021bei la nivel de popula\u021bie.<\/p>\n

Contextul este unul alarmant. \u00cen prezent, aproximativ 900.000 de persoane sufer\u0103 de demen\u021b\u0103 \u00een Regatul Unit. Cifra este estimat\u0103 s\u0103 dep\u0103\u0219easc\u0103 1,6 milioane p\u00e2n\u0103 \u00een 2040. Demen\u021ba este principala cauz\u0103 de deces \u00een Marea Britanie, cu peste 74.000 de decese anual.<\/p>\n

Exper\u021bi de renume mondial au avertizat recent c\u0103 milioane de cazuri ar putea fi prevenite prin schimb\u0103ri simple ale stilului de via\u021b\u0103 \u0219i 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","protected":false},"excerpt":{"rendered":"
