Leg\u0103tura dintre somnul de slab\u0103 calitate \u0219i problemele de s\u0103n\u0103tate mintal\u0103 ar putea fi asociat\u0103 cu deficite \u00een regiunile cerebrale implicate \u00een blocarea g\u00e2ndurilor nedorite, potrivit cercet\u0103rilor efectuate la Universitatea East Anglia (UEA)<\/a>, citate de ScienceDaily<\/a>.<\/p>\n

Problemele de somn joac\u0103 un rol central \u00een apari\u021bia \u0219i men\u021binerea multor tulbur\u0103ri de s\u0103n\u0103tate mintal\u0103, \u00eens\u0103 cauzele acestei conexiuni sunt \u00een continuare pu\u021bin \u00een\u021belese.<\/p>\n

Un nou studiu, publicat \u00een Proceedings of the National Academy of Sciences (PNAS)<\/a>, ofer\u0103 informa\u021bii noi despre mecanismele cognitive \u0219i neuronale care leag\u0103 somnul de s\u0103n\u0103tatea mintal\u0103. Aceste descoperiri ar putea contribui la dezvoltarea unor tratamente \u0219i strategii de prevenire mai eficiente pentru condi\u021bii precum depresia \u0219i anxietatea.<\/p>\n

Dr. Marcus Harrington, lector la \u0218coala de Psihologie a Universit\u0103\u021bii East Anglia (UEA) \u0219i autor principal al studiului \u201eMemory control deficits in the sleep-deprived human brain\u201d, a colaborat cu cercet\u0103tori de la universit\u0103\u021bile din York, Cambridge, Sussex \u0219i Queen\u2019s University (Canada).<\/p>\n

Deficitele de control al memoriei dup\u0103 pierderea somnului<\/strong><\/p>\n

Cercetarea a folosit metode de imagistic\u0103 cerebral\u0103 pentru a ar\u0103ta, pentru prima dat\u0103, c\u0103 problemele de control al memoriei ap\u0103rute dup\u0103 lipsa somnului sunt legate de dificult\u0103\u021bi \u00een activarea zonelor din creier care ajut\u0103 la oprirea recuper\u0103rii memoriei. Restabilirea acestor zone \u00een timpul nop\u021bii ar fi influen\u021bat\u0103 de somnul REM (somnul cu mi\u0219care rapid\u0103 a ochilor).<\/p>\n

\u201eAmintirile unor experien\u021be nepl\u0103cute pot invada con\u0219tientul, deseori ca reac\u021bie la anumite elemente declan\u0219atoare\u201d, explic\u0103 Dr. Harrington.<\/p>\n

\u201eDe\u0219i astfel de amintiri intruzive sunt o problem\u0103 ocazional\u0103 pentru majoritatea oamenilor, ele pot deveni recurente, intense \u0219i deranjante \u00een cazul persoanelor cu tulbur\u0103ri precum depresie, anxietate \u0219i tulburare de stres post-traumatic.\u201d<\/p>\n

Dr. Harrington sugereaz\u0103 c\u0103 amintirile joac\u0103 un rol-cheie \u00een modul \u00een care interpret\u0103m lumea din jur, iar e\u0219ecul \u00een controlul memoriei ar putea explica par\u021bial motivul pentru care privarea de somn duce la deregl\u0103ri emo\u021bionale. O \u00een\u021belegere mai profund\u0103 a mecanismelor care declan\u0219eaz\u0103 amintirile intruzive poate ajuta la ameliorarea st\u0103rii emo\u021bionale \u0219i la atenuarea poverii globale a tulbur\u0103rilor mintale.<\/p>\n

Metodologia studiului<\/strong><\/p>\n

Cercet\u0103torii au recrutat 85 de adul\u021bi s\u0103n\u0103to\u0219i, c\u0103rora li s-a cerut s\u0103 suprime amintiri nedorite, \u00een timp ce activitatea cerebral\u0103 era monitorizat\u0103 prin imagistic\u0103 func\u021bional\u0103 cu rezonan\u021b\u0103 magnetic\u0103 (fMRI). Jum\u0103tate dintre participan\u021bi au petrecut o noapte de somn normal \u00eentr-un laborator specializat, \u00een vreme ce cealalt\u0103 jum\u0103tate a r\u0103mas treaz\u0103 toat\u0103 noaptea.<\/p>\n

\u00cen timpul procesului de suprimare a memoriei, participan\u021bii odihni\u021bi au prezentat o activare sporit\u0103 a cortexului prefrontal dorsolateral drept \u2014 regiunea cerebral\u0103 responsabil\u0103 de controlul g\u00e2ndurilor, emo\u021biilor \u0219i ac\u021biunilor \u2014 fa\u021b\u0103 de cei priva\u021bi de somn. De asemenea, \u00een grupul odihnit s-a observat o activitate mai redus\u0103 \u00een hipocamp \u2014 zon\u0103-cheie pentru recuperarea memoriei \u2014 \u00een timpul \u00eencerc\u0103rilor de a suprima amintiri nepl\u0103cute.<\/p>\n

Printre cei care au dormit \u00een laborator, participan\u021bii care au petrecut mai mult timp \u00een faza de somn REM au eviden\u021biat o mai mare capacitate de a activa cortexul prefrontal dorsolateral drept \u00een timpul suprim\u0103rii memoriei. Acest lucru sugereaz\u0103 c\u0103 somnul REM are un rol \u00een refacerea func\u021biei de control prefrontal, crucial\u0103 pentru prevenirea accesului amintirilor nedorite \u00een con\u0219tient.<\/p>\n

\u201e\u00cen ansamblu, concluziile noastre subliniaz\u0103 c\u0103 somnul joac\u0103 un rol fundamental \u00een men\u021binerea controlului at\u00e2t asupra amintirilor, c\u00e2t \u0219i asupra fluxului de g\u00e2nduri\u201d, afirm\u0103 Dr. Harrington.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
