I-HDL ephantsi okanye i-High LDL i-Cholesterol inokuphakamisa ingozi yeMemori yokulahleka
Ukuba unenkathazo yokukhumbula ukufumana i- cholesterol yakho, mhlawumbi kukho isizathu-ukufunyanwa kukufumanisa ukuba ukulahlekelwa kwememori kuhambelana namazinga aphantsi kwe- HDL , "i-cholesterol enhle." Abaphandi bakholelwa ukuba ukulahlekelwa kweememori kungakhokelela ekudemeni kwengqondo kamva ebomini.
Izifundo Khangela i-HDL ephantsi okanye iLDL ephakamileyo iphakamisa ingozi yokuLawulwa kweMemori
Isifundo, esapapashwa ngoJulayi 2008 kwi- Arteriosclerosis, iThrombosis ne-Vascular Biology: I-Journal ye-American Heart Association , yabona ukuba, xa uneminyaka engama-60 ubudala, amadoda nabesifazane abanamaqondo aphantsi kwi-HDL babengama-53% amathuba okuba balahlekelwe imemori kunabo ngamanqanaba aphezulu.
Ukusetyenziswa kwezidakamizwa ze- statin ukuphakamisa amazinga e-HDL okanye amanqanaba aphantsi e- LDL , "i-cholesterol embi," ayifumananga ukuba nayiphi na inxaxheba kunye nokulahlekelwa kwememori kweso sifundo.
Kwaye akusikho okokuqala abaphandi bafumene unxibelelwano phakathi kwe-cholesterol kunye neengxaki zememori. Uphando olwenziwa ngo-2002, olupapashwe kwi- Archives of Neurology , lwafumanisa ukuba abafazi abanamazinga aphezulu e-LDL babekhulile amazinga okukhubazeka kwengqondo, kuquka ukulahleka kwememori. Iminyaka emine kamva, izifundo zezifundo eziye zanciphisa amazinga abo e-LDL zanciphisa amathuba abo okubandezeleka kwengqondo.
Ngo-2004, isifundo esivela eNetherlands safumanisa ukuba ukutya okuphezulu kwi-cholesterol kunye namafutha azalisiweyo kwakuxhomekeke engozini yokunyuka kwengqondo phakathi kwezifundo zokufunda. Okokufunda , okwenziwe kwiphephancwadi ye- Neurology , kwagqitywa ukuba ukusetyenziswa kweentlanzi kunye neoli yeentlanzi kwakudibene nomngcipheko ophantsi wokuncipha kwengqondo; idumela leentlanzi ngokuthi "ukutya kokuphefumula" kubonakala kuhambelana.
Ukusombulula i-Mystery of Cholesterol kunye neLindleko yokulahleka
I-cholesterol ithinte njani imemori kunye nomsebenzi wokuqonda? Impendulo eqondileyo yalo mbuzo ihlala ingummangaliso. Abaphandi bacacisa ukuba i-HDL inokuphucula imemori ngeendlela ezininzi. I-HDL inezixhobo ezichasayo nezikhuselekisayo, ezinokuphucula ukusebenza kwengqondo.
I-HDL inokuthintela ukwakheka kwe- beta-amyloid , ehambelana neelayi ezenza kwiisisongo zobuchopho bezigulane ze- Alzheimer .
Abanye abaphandi, njengoWilliam Connor, MD, unjingalwazi weyeza kwiOregon yezeMpilo neYunivesithi yasePortland, eOregon, bakholelwa ukuba i-cholesterol ithintela ubuchopho ngokusebenza ngokukodwa ngokusebenzisa ikhonkco phakathi kweLDL kunye nemivimbo , ebangelwa ukusekwa kweplate kwimida yegazi ngengqondo.
UConnor, onguchwepheshe kwi- atherosclerosis (inkqubo apho idiphozithi zakha kwiimitha zeetriyiti). Kwaye, uyongezelela, "ukubetha kungabangela ukulahlekelwa kwememori."
Ukuphononongwa kweengxelo ngo-2011 kwaphawula ukuba "i-cholesterol ibonakala ixhamle ngokusondeza ngokuveliswa kweentlanzi ze-amyloid," ezikhula kwisifo se-Alzheimer. Ininzi yezifundo ababezijongayo zafumana ubudlelwane phakathi kwe-cholesterol ne-Alzheimer's disease.
Yintoni Ongayenza Ngayo i-Cholesterol kunye neMemori Yakho
Nangona abaphandi beqhubeka behlanganisa i-puzzle ye-cholesterol kunye nokulahleka kwememori, kukho into ongayenza ngoku ukuba unenkxalabo malunga namazinga e-cholesterol yakho.
Ngokutsho kwe-American Heart Association, ukusetyenziswa rhoqo kunye nokuphepha ukutshaya umsila kunokunceda konke ukunyusa izinga le-cholesterol.
Izidakamizwa ezinciphisa i-cholesterol zinokukunceda izigulane zifezekise iinjongo zabo ze-cholesterol.
Kwaye, ke, ukutya ukutya okunempilo kukhuthazwa kakhulu. Ukongezelela ekukhuseleni amafutha apheleleyo kunye ne-cholesterol, uDkt. Connor kunye nezinye iingcali zikhuthaza abantu ukuba bafumane ininzi yefiber , badle iziqhamo kunye nemifuno rhoqo kunye neenkonzo ezimbini okanye iintlobo zeentlanzi ngeveki.
