I-HDL ephansi noma i-High LDL Cholesterol Ingabangela Ingozi Yokulahlekelwa Kwememori
Uma unenkinga yokukhumbula ukuthola i- cholesterol yakho ihlolwe, mhlawumbe kunesizathu - isifundo sithola ukuthi ukulahleka kwememori kuhlotshaniswa namazinga aphansi e- HDL , "i-cholesterol enhle." Abacwaningi bakholelwa ukuthi ukulahlekelwa kwememori kungase kuholele ekudemeni kwengqondo kamuva ekuphileni.
Izifundo Thola i-HDL ephansi noma i-High LDL Iphakamisa Ingozi Yokulahlekelwa Kwememori
Ucwaningo olwenziwe ngoJulayi 2008 ku- Arteriosclerosis, i-Thrombosis ne-Vascular Biology: I-Journal of the American Heart Association , yathola ukuthi, lapho abaneminyaka engama-60 ubudala, amadoda nabesifazane abanezinga eliphansi le-HDL babengama-53% ngaphezulu okuba nokulahlekelwa inkumbulo kunabo namazinga aphezulu.
Ukusetshenziswa kwezidakamizwa ze- statin ukukhulisa amazinga we-HDL noma amazinga aphansi e- LDL , "i-cholesterol embi," ayitholakalanga ukuthi inanoma iyiphi inhlangano yokulahlekelwa kwememori esifundweni.
Futhi lesi akusona okokuqala abacwaningi bathole ukuxhumana phakathi kwe-cholesterol nezinkinga zememori. Ucwaningo olwenziwe ngo-2002, olushicilelwe kwi- Archives of Neurology , lathola ukuthi abesifazane abanamazinga aphakeme e-LDL babekhuphule amazinga okukhubazeka kwengqondo, kuhlanganise nokulahleka kwememori. Eminyakeni emine kamuva, izifundo zezifundo ezanciphisa amazinga abo e-LDL nazo zanciphisa amathuba abo okubhekana nokukhubazeka kwengqondo.
Ngo-2004, isifundo esivela eNetherlands sathola ukuthi ukudla okunamafutha amaningi e-cholesterol namafutha aphelele kwakuhlobene nengozi eyengeziwe yokuncipha kwengqondo phakathi kwezifundo zokufunda eziphakathi. Lelo cwaningo, eshicilelwe encwadini ye- Neurology , futhi laphetha ngokuthi ukusetshenziswa kwezinhlanzi nezinhlanzi ezinhlanzi kwakuhlobene nengozi ephansi yokuncipha kwengqondo; idumela lezinhlanzi ngokuthi "ukudla kobuchopho" kubonakala sengathi lingaqondile.
Ukuxazulula Imfihlakalo Ye-Cholesterol ne-Memory Loss
I-cholesterol ithinta kanjani inkumbulo nokusebenza kwengqondo? Impendulo eqondile yalo mbuzo isalokhu imfihlakalo. Abacwaningi bacabanga ukuthi i-HDL ingathuthukisa inkumbulo ngezindlela eziningi. I-HDL inezakhiwo eziphikisayo nezivimbela i-antioxidant, ezingase zithuthukise ukusebenza kobuchopho.
I-HDL ingavimbela nokubunjwa kwe- beta-amyloid , ehambisana namapulethi afaka izicubu zobuchopho zeziguli ze- Alzheimer .
Abanye abacwaningi, njengoWilliam Connor, MD, uprofesa wezokwelapha e-Oregon Health and Science University e-Portland, e-Oregon, bakholelwa ukuthi i-cholesterol ithinta ukusebenza kobuchopho ngokuyinhloko ngokuxhumanisa phakathi kweLDL nemivimbo , okubangelwa ukubunjwa kwamapule emithanjeni yegazi ubuchopho.
UConnor, onguchwepheshe we- atherosclerosis , uthi: "Amazinga aphakeme e-cholesterol egazini angenza ukuba i-plaque ibekwe emithanjeni yegazi." Futhi uyanezela, "ukulimala kungabangela ukulahlekelwa inkumbulo."
Ukubuyekezwa kwezifundo ngo-2011 kwaphawula ukuthi "i-cholesterol ibonakala ihlotshaniswa kakhulu nokwakhiwa kwama-amyloid plaques," okuthuthukisa isifo se-Alzheimer's. Iningi lezifundo ababezibuka zathola inhlangano phakathi kwe-cholesterol ne-Alzheimer's disease.
Ongakwenza Ngokuphathelene neCholesterol neMemori Yakho
Ngesikhathi abacwaningi beqhubeka behlanganisa iphazili ye-cholesterol nokulahlekelwa kwememori, kuningi ongakwenza manje uma ukhathazekile ngamazinga akho e-cholesterol.
Ngokusho kwe-American Heart Association, ukuzivocavoca njalo nokugwema ukubhema ugwayi kungakusiza wonke amazinga e-cholesterol.
Izidakamizwa ezinciphisa izidakamizwa nazo zingasiza iziguli ukuba zifinyelele imigomo yazo ye-cholesterol.
Futhi-ke, ukudla ukudla okunempilo kunenconywa kakhulu. Ngaphezu kokugwema amafutha agcwele kanye ne-cholesterol, uDkt. Connor nabanye ochwepheshe bakhuthaza abantu ukuba bathole i- fibre eningi, badle izithelo nemifino njalo futhi babe nesisetshenziswa esisodwa noma ezimbili senhlanzi ngesonto.
