Okokuqala, abaphandi baye bachonga imimandla ethile yengqondo eyonakaliswe luxinzelelo lwegazi oluphezulu kwaye inokuba negalelo ekucothiseni iinkqubo zokucinga kunye nokunciphisa ukuphambana kwengqondo.
Uxinzelelo lwegazi oluphezulu luyaziwa ngokuba lubandakanyeka kwisifo sengqondo esiyingozi kunye nomonakalo ekusebenzeni kwengqondo. Ngoku, uphando olupapashwe kwi "European Heart Journal" ichaza okokuqala iindlela ezibandakanyekayo kule nkqubo.
I-HTA luluntu oluvaliweyo kwaye luchaphazela ubuncinane i-30% yabantu kwihlabathi jikelele. Uphononongo lubonise ukuba ichaphazela indlela ingqondo esebenza ngayo kwaye inokubangela utshintsho lwexesha elide. Nangona kunjalo, kude kube ngoku bendingayazi ncam indlela uxinzelelo lwegazi oluyonakalisa ngayo ingqondo kwaye yeyiphi imimandla ethile echaphazelekayo.
"Kudala kusaziwa ukuba uxinzelelo lwegazi luyingxaki yokuncipha kwengqondo, kodwa indlela eyonakalisa ngayo ingqondo ayicacanga. Olu pho nonongo lubonisa ukuba imimandla ethile yengqondo isengozini enkulu yomonakalo ovela kuxinzelelo lwe-arterial, enokunceda ukuchonga abantu abasengozini yokuncipha kwengqondo kumanqanaba okuqala kwaye banokujoliswa kunyango ngokufanelekileyo. kwixesha elizayo, "ekhokelwa yi-study co -umbhali uNjingalwazi uJoanna Wardlaw, iNtloko yeNzululwazi ye-Neuroimaging kwiYunivesithi yase-Edinburgh.
Uphando luqokelele ulwazi oluvela kwindibaniselwano yengqondo ye-brain resonance imaging (MRI), uhlalutyo lwezofuzo kunye nedatha yokujonga ukusuka kubathathi-nxaxheba be-30.000 kwi-UK Biobank yophando ukujonga umphumo wegazi eliphezulu (HBP) ekusebenzeni kwengqondo.
Abaphandi kamva baqinisekisa iziphumo zabo kwiqela elikhulu elahlukileyo labaguli e-Itali.
“Sisebenzisa le ndibaniselwano yemifanekiso, imfuza, kunye nedatha yokujonga, siye sachonga iindawo ezithile zobuchopho ezichatshazelwa kukwanda koxinzelelo lwegazi. Ukucinga ukuba le ndawo inokuthi ichaphazele uxinzelelo lwegazi oluphezulu luchaphazela umsebenzi wokuqonda, njengokulahleka kwememori, izakhono zokucinga kunye nokuphazamiseka kwengqondo, "kuchaza uTomasz Guzik, uNjingalwazi weCardiovascular Medicine kwiYunivesithi yase-Edinburgh (eUnited Kingdom) kunye ne-Faculty. yeMedicine yeYunivesithi yaseJagiellonian yaseKrakow (ePoland), owayekhokela uphando.
Uxinzelelo lwegazi yimbumba evalelweyo, echaphazela phantse i-30% yabantu kwihlabathi liphela
Ngokukodwa, sifumene ukuba utshintsho kwiindawo ezintsha zobuchopho zidibaniswa noxinzelelo lwegazi oluphezulu kunye nokusebenza kakubi kwengqondo: i-putamen, isakhiwo esingafunekiyo kwisiseko secala eliphambili lengqondo, elijongene nokuhamba rhoqo. kwaye zinempembelelo kwiindidi ezininzi zokufunda, i-thalamic ray yangaphambili, i-corona radiata yangaphambili, kunye nengalo yangaphambili ye-capsule yangaphakathi, enemiba emhlophe edibanisa kwaye yenza umqondiso phakathi kweendawo ezahlukeneyo zobuchopho. Imitha yethalamic yangaphambili ibandakanyeka kweminye imisebenzi yesigqeba, njengokucwangcisa imisebenzi yemihla ngemihla elula nentsonkothileyo, ngelixa le mimandla mibini ibandakanyeka ekwenzeni izigqibo kunye nokulawula iimvakalelo.
Utshintsho kule ndawo lubandakanya ukunciphisa umthamo wengqondo kunye nobungakanani bommandla ongaphezulu kwi-cortex ye-cerebral, utshintsho kunxibelelwano phakathi kweendawo ezahlukeneyo zengqondo, kunye nokutshintsha kwindlela yokusebenza kwengqondo.
kwizigulana
UGuzik wongezelela ukuba xa iziphumo zakhe ziqinisekisiwe ngokuhlalutya iqela lezigulane zase-Italiya ezazine-AHT, "sabona ukuba iindawo zengqondo ezichongiweyo zichaphazeleke ngokwenene."
Abaphandi banethemba lokuba iziphumo ziya kunceda ukuphuhlisa iindlela ezintsha zokunyanga ukuhla kwengqondo kubantu abanoxinzelelo lwegazi oluphezulu. “Ukufunda ngofuzo kunye neeproteni kwezi zakhiwo zobuchopho kunokukunceda uqonde ukuba uxinzelelo lwegazi oluyichaphazela njani ingqondo kwaye lubangela iingxaki zengqondo. Kwakhona, ngokujonga le mimandla ethile yengqondo, sinokuqikelela ukuba ngubani oza kuphuhlisa ukulahlekelwa kwememori kunye nokuphazamiseka kwengqondo ngokukhawuleza kwimeko yoxinzelelo lwegazi oluphezulu. "
NgokukaGuzik, oku kunokusebenzela ukuyila unyango olungqongqo ngakumbi ukuthintela ukuphuhliswa kokuphazamiseka kwengqondo kwizigulane ezisengozini enkulu.
Umbhali wokuqala wophononongo, uNjingalwazi uMateusz Siedlinski, naye umphandi kwiYunivesithi yaseJagiellonian School of Medicine, uthi uphononongo, ngokokuqala ngqa, "luchonge iindawo ezithile kwingqondo enokuthi idityaniswe noxinzelelo lwegazi." kunye nokuqonda umsebenzi.
