\n\u00cen urma examin\u0103rilor RMN, creierul fetelor a ap\u0103rut cu 4,2 ani mai \u00een v\u00e2rst\u0103 dec\u00e2t era de a\u015fteptat dup\u0103 izolare, comparativ cu 1,4 ani pentru b\u0103ie\u0163i, scrie The Guardian.<\/p>\n
\nEchipa de cercet\u0103tori, condus\u0103 de profesorul Patricia Kuhl, a analizat RMN-urile la creierele a 160 de copii cu v\u00e2rste \u00eentre 9 \u015fi 17 ani. Prima serie deanalize s-a f\u0103cut \u00een 2018, \u00eenainte de pandemie. Folosind aceste date, cercet\u0103torii au creat un model al modului \u00een care cortexul creierului se sub\u0163iaz\u0103 \u00een mod normal \u00een timpul adolescen\u0163ei.<\/p>\n
\n\u00cen 2021 \u015fi 2022, dup\u0103 perioadele de izolare, aceia\u015fi participan\u0163i, acum cu v\u00e2rste \u00eentre 12 \u015fi 16 ani, au fost reexamina\u0163i.<\/p>\n
\nRezultatele au fost \u015focante: creierul fetelor p\u0103rea \u00een medie cu 4,2 ani mai b\u0103tr\u00e2n dec\u00e2t era de a\u015fteptat. La b\u0103ie\u0163i, \u00eemb\u0103tr\u00e2nirea prematur\u0103 era de doar 1,4 ani.<\/p>\n
\nFetele au prezentat modific\u0103ri \u00een 30 de zone ale creierului, \u00een ambele emisfere \u015fi \u00een to\u0163i lobii. La b\u0103ie\u0163i, modific\u0103rile au fost observate \u00eentr-o singur\u0103 zon\u0103 a creierului.<\/p>\n
\nProfesorul Kuhl explic\u0103: \u201eAm fost \u015foca\u0163i de aceste date, de faptul c\u0103 diferen\u0163a este at\u00e2t de dramatic\u0103. Fetele discut\u0103 la nesf\u00e2r\u015fit \u015fi \u00ee\u015fi \u00eemp\u0103rt\u0103\u015fesc emo\u0163iile. Ele sunt mult mai dependente de scena social\u0103 pentru bun\u0103starea lor \u015fi pentru dezvoltarea lor neuronal\u0103, fizic\u0103 \u015fi emo\u0163ional\u0103 s\u0103n\u0103toas\u0103”.<\/p>\n
\nAmbele sexe au prezentat modific\u0103ri \u00eentr-o regiune a creierului legat\u0103 de vedere. La fete \u00eens\u0103, schimb\u0103rile au afectat \u015fi zonele responsabile de cogni\u0163ia social\u0103, procesarea emo\u0163iilor \u015fi \u00een\u0163elegerea limbajului.<\/p>\n
\nDe\u015fi nu este clar dac\u0103 aceste modific\u0103ri vor avea consecin\u0163e negative pe termen lung, ele ridic\u0103 \u00eengrijor\u0103ri cu privire la s\u0103n\u0103tatea mintal\u0103 a adolescen\u0163ilor \u015fi capacitatea lor de \u00eenv\u0103\u0163are. Atrofia cortical\u0103 prematur\u0103 a fost asociat\u0103 \u00een trecut cu adversitatea timpurie \u015fi un risc crescut de tulbur\u0103ri neuropsihiatrice.<\/p>\n
\nDr. Ian Gotlib de la Universitatea Stanford, care a raportat modific\u0103ri similare, subliniaz\u0103: \u201eEste important s\u0103 recunoa\u015ftem c\u0103, de\u015fi pandemia s-a \u00eencheiat \u00een mare parte, efectele stresului pandemiei sunt \u00eenc\u0103 prezente pentru copii \u015fi adolescen\u0163i\u201d.<\/p>\n
\n\u00cen lumina acestor descoperiri, exper\u0163ii recomand\u0103 p\u0103rin\u0163ilor s\u0103 aib\u0103 conversa\u0163ii deschise cu adolescen\u0163ii lor despre experien\u0163ele din timpul pandemiei. Profesorul Kuhl sugereaz\u0103: \u201eEste important s\u0103 \u00ee\u015fi invite adolescen\u0163ii la o cafea, la un ceai, la o plimbare, pentru a deschide u\u015fa conversa\u0163iei\u201d.<\/p>\n","protected":false},"excerpt":{"rendered":"
