Abanye abantu bangezwa okuthile kanye futhi bakukhumbule iminyaka, kanti abanye badinga izikhumbuzo ezimbalwa ukuze ulwazi lunamathele. Inkumbulo enhle iye yaxhunyaniswa nezici eziningi, okuhlanganisa ukuba namazinga aphansi okuvuvukala emzimbeni wonke kanye nokuthola inala yama-antioxidants. Manje, un ukutadisha muva nje enyatheliswa kumagazini i-Brain. engeza okunye ohlwini: igazi elihle ekhanda lakho.
Abacwaningi baseJalimane baqashe abantu abangu-47, abaneminyaka esukela kwengama-45 kuya kwengama-89, futhi basebenzisa i-high-resolution magnetic resonance imaging (MRI) ukuze bahlole ukutholakala kwegazi ku-hippocampus, indawo encane ebuchosheni ebhekwa “njengesikhungo sokulawula.” . Abahlanganyeli nabo bahlaziywa ku ukusebenza kwenkumbulo, isikhathi sokunaka, nokuqonda inkulumo.
Abangu-XNUMX babahlanganyeli kutholakale ukuthi banokungajwayelekile emithanjeni yegazi ebuchosheni babo okuthinte ukuhlinzekwa kwegazi ku-hippocampus. Leli qembu liphinde lathola amaphuzu aphansi ekuhlolweni kwengqondo, okuholela abacwaningi ukuba baphethe ngokuthi ukulethwa kwegazi nomoya-mpilo ngemithambo yegazi kungaba nomthelela omkhulu ekusebenzeni kwenkumbulo.
Lolu cwaningo lukhombisa a ukuxhumana okucacile phakathi kokunikezwa kwegazi ku-hippocampus nokusebenza kwengqondo. Okusho ukuthi, ukugeleza kwegazi lobuchopho kungase kudlale indima ebalulekile ekwehleni kokusebenza kwenkumbulo okubangelwa ubudala noma isifo.
Kuphinde kukholakala ukuthi ezinye izici zokuphila, ezifana umsebenzi, kungaba nomthelela ekwakhiweni kwemithambo yegazi ehlinzeka nge-hippocampus, kanye nokusebenza kahle kokuthi ilihambisa kanjani igazi kuleyo ndawo.
Ucwaningo olwengeziwe luzodingeka ukuze kuqinisekiswe lokho kungenzeka, kodwa izifundo zangaphambilini zisikisela ukuthi lapho ukuvivinya umzimba kumpompa igazi, kunengxenye yalo ephelela ebuchosheni, futhi lowo mphumela ungase ube nenzuzo ekuthuthukiseni umsebenzi wokuqonda.
Ucwaningo oluncane lwango-2011 lwabesifazane asebekhulile, ithole ukuthi ukuhamba ngokushesha imizuzu engama-30 kuye kwengama-50 izikhathi ezintathu kuya kwezine ngeviki kuthuthukisa ukugeleza kwegazi ukuya ebuchosheni kufika ku-15%.. Labo bacwaningi baphawula ukuthi igazi aligcini nje ngokuletha umoya-mpilo nezinye izakhi ebuchosheni, kodwa futhi isusa imfucuza ye-metabolic njengeprotheyini ye-beta amyloid, eye yathinteka ekuthuthukisweni kwesifo i-Alzheimer's.
Olunye ucwaningo lwaphetha ngokuthi ukuzivocavoca kungavimbela noma kubambezele ukwehla kwengqondo ngokwenza ngcono izinga le-atrophy yobuchopho nokugeleza kwegazi. Kungakhathaliseki ukuthi yiziphi izindlela ezisebenzayo, kusobala ukuthi amazinga akhuphukayo okusebenza komzimba azuzisa ngaphezu kwemisipha nje: kungase futhi kube i-booster ebalulekile yobuchopho.
