I-boxing ingumdlalo oyingozi wokuxhumana nabo bobabili ochwepheshe nabaqalayo. Ukutholwa kwesayensi kwakamuva kuxwayisa ukuthi abashayisibhakela abathola ukulimala ekhanda okuphindaphindiwe bangase babe namathuba aphindwe kathathu okuba ne-Alzheimer's.
Abacwaningi baseBoston University bathola ukuthi izilonda endabeni emhlophe yobuchopho zingavela kuma-MRI scan. Ingabe i-white matter hyperintensitiesa zivela njengamachashaza akhanyayo ekuhlolweni kobuchopho futhi zingabonisa izimo ezifana nomfutho wegazi ophezulu. Kodwa-ke, ososayensi bathole ukuthi lezi zimpawu zivame kakhulu kubasubathi abazilolonga thintana nezemidlalo isikhathi eside noma sibe nokulimala okuningi ekhanda.
Ikhono lokubona kalula izinkomba zokulimala kobuchopho kuma-MRIs lingasiza odokotela. Lokhu kungavuna ucwaningo nokutholwa kusenesikhathi kokulimala okudalwe umthelela wekhanda.
Imithelela ephindaphindayo yandisa ukulimala
Izinzuzo ezemidlalo ezingazenzela intsha zidlula kude iqiniso lokuthi zidlala izingoma ezishisayo ngaphansi kwezimo ezilawulwa ngokuqinile. Ngokuvamile, abashayisibhakela bavame ukuhlolwa kodokotela futhi bahlolwe ubuchopho, kodwa abanye bangase benqabe.
Kulolu cwaningo, ososayensi bahlole abantu abashonile abangu-75 abake baba nenkinga yekhanda ngesikhathi sempilo yabo futhi bavuma ukunikela ngobuchopho babo kwisayensi yezokwelapha ngemuva kokushona, ngokwesilinganiso seminyaka engu-67.
Imiphumela ibonisa ukuthi i-white matter hyperintensities ingabamba ukulimala kwengqondo isikhathi eside kubantu abanomlando we amagalelo aphindaphindayo ekhanda. I-MRI ingaba ithuluzi elisebenzayo lokutadisha imiphumela yekhanda eliphindaphindayo kundaba emhlophe yobuchopho ngenkathi umshayisibhakela esaphila.
Abasubathi bekungabadlali bebhola baseMelika ikakhulukazi, abanye bekungabasubathi abavela emidlalweni yokuxhumana efana nesibhakela noma ibhola likanobhutshuzwayo, noma omakadebona bezempi. Ososayensi baphinde babheka amarekhodi ezempilo omuntu ngamunye, okuhlanganisa nokuhlolwa kobuchopho okwathathwa ngesikhathi abantu besaphila, baphinde bahlangana nabathandekayo ukuze bahlole izimo zokuwohloka komqondo.
Ngokusekelwe emiphumeleni yokuhlolwa kwesidumbu, kutholwe ukuthi amaphesenti angama-71 ezifundo, abantu abangama-53 sebebonke, babenazo I-encephalopathy ebuhlungu engapheli, isifo se-neurodegenerative esihambisana nomthelela ophindaphindiwe ekhanda ongaholela ekuwohlokeni komqondo.
Abashayisibhakela abasebancane basengozini enkulu
Ukuskena kobuchopho kwembula ukuthi kuwo wonke umehluko weyunithi kumthamo we-white matter hyperintensity, amathuba okuba nesifo esibi semithambo emincane nokulimala kwento emhlophe yobuchopho anda kabili.
Lokhu kwakuhambisana nokunyuka okuphindwe kathathu kwamathuba okuba ne- ukwanda kwamaprotheni tau engxenyeni engaphambili, intuthuko eyi-biomarker yezifo eziningana zobuchopho eziqhubekayo, kuhlanganise nesifo i-Alzheimer's.
Phakathi kwabasubathi, ukuba ne-white matter hyperintensities kuhlotshaniswa neminyaka eminingi yesibhakela neminye imidlalo yokuxhumana. Ngokulandelayo, lokhu kuhlobene nemiphumela emibi kakhulu kuhlu lwemibuzo mayelana nobunzima bokwenza imisebenzi yansuku zonke.
