\"creier\"<\/a>Cel mai mare studiu de imagistic\u0103 a creierului, desf\u0103\u015furat recent \u00een SUA, a reu\u015fit s\u0103 aduc\u0103 o \u00een\u0163elegere mai bun\u0103 a procesului de \u00eemb\u0103tr\u00e2nire a creierului \u015fi a factorilor care \u00eel accelereaz\u0103, prin evaluarea circula\u0163iei s\u00e2ngelui \u00een creier.<\/p>\n

Cercet\u0103tori de la Amen Clinics, John’s Hopkins University, University of California, Los Angeles \u015fi the University of California, San Francisco, au studiat peste 60 000 de scanuri CT ale peste 30 000 de persoane cu v\u00e2rste de la 9 luni p\u00e2n\u0103 la 105 ani.
\nEchipa de cercet\u0103tori condus\u0103 de psihiatrul Daniel G. Amen a urm\u0103rit s\u0103 identifice tulbur\u0103ri \u015fi comportamente uzuale care duc la \u00eemb\u0103tr\u00e2nirea timpurie a creierului, cu scopul final de a \u00eencetini sau chiar stopa acest proces prin tratarea tulbur\u0103rilor sau eliminarea comportamentelor de risc.<\/p>\n

Pentru a identifica aceste tulbur\u0103ri psihiatrice care au un impact negativ asupra v\u00e2rstei creierului, cercet\u0103torii au analizat scanurile CT func\u0163ionale ale pacien\u0163ilor unei clinici psihiatrice importante, unde exista un spectru larg de tulbur\u0103ri psihiatrice, inclusiv tulburarea bipolar\u0103, schizofrenia \u015fi deficitul de aten\u0163ie.<\/p>\n

Au fost studiate 128 regiuni ale creierului pentru a se putea estima v\u00e2rsta cronologic\u0103 a pacien\u0163ilor. Prognozarea, pe baza scanurilor CT, a unei v\u00e2rste mai \u00eenaintate fa\u0163\u0103 de v\u00e2rsta cronologic\u0103 efectiv\u0103 a acestora a fost interpretat\u0103 drept \u00eemb\u0103tr\u00e2nire timpurie a creierului.<\/p>\n

Studiul a ar\u0103tat c\u0103 anumite tulbur\u0103ri psihiatrice \u015fi comportamente pot prognoza \u00eemb\u0103tr\u00e2nirea accelerat\u0103 a creierului, mai ales schizofrenia, care a ar\u0103tat o \u00eemb\u0103tr\u00e2nire mai rapid\u0103 cu 4 ani, abuzul de canabis cu 2,8 ani, tulburarea bipolar\u0103 cu 1,6 ani, iar deficitul de aten\u0163ie cu 1,4 ani.<\/p>\n

Important de notat, cercet\u0103torii nu au descoperit nicio leg\u0103tur\u0103 \u00eentre depresie \u015fi \u00eemb\u0103tr\u00e2nirea accelerat\u0103 a creierului, ceea ce \u00eei face pe cercet\u0103tori s\u0103 cread\u0103 c\u0103 exist\u0103 alte tipare cerebrale pentru aceast\u0103 condi\u0163ie.<\/p>\n

Speciali\u015ftii din domeniu sunt unanimi c\u0103 asemenea studii cu mul\u0163i subiec\u0163i sunt esen\u0163iale pentru \u00een\u0163elegerea complet\u0103 a func\u0163ion\u0103rii creierului \u015fi a mecanismelor care \u00eei men\u0163in structura \u015fi func\u0163ionarea pe m\u0103sur\u0103 ce \u00eenaint\u0103m \u00een v\u00e2rst\u0103.<\/p>\n

Ei sunt, de asemenea, \u00eencrez\u0103tori c\u0103 identificarea c\u00e2t mai multor factori cu efect asupra \u00eemb\u0103tr\u00e2nirii creierului, inclusiv tulbur\u0103rile psihiatrice sau abuzul de substan\u0163e, \u00eei va ajuta s\u0103 valideze noi abord\u0103ri pentru men\u0163inerea func\u0163iei cognitive la v\u00e2rste \u00eenaintate.<\/p>\n
