Bhokisi mutambo une njodzi kune vese nyanzvi uye vanotanga. Kuwanikwa kwesainzi kuchangoburwa kunoyambira kuti vatambi vetsiva vanosangana nekukuvadzwa mumusoro kwakadzokororwa vangangowedzera katatu mukana wekukudziridza Alzheimer's.
Vatsvagiri veBoston University vakawana kuti maronda ari muchena nyaya yehuropi anogona kuoneka paMRI scans. Are white matter hyperintensitiesa dzinoratidza semavara anopenya pahuropi uye dzinogona kuratidza mamiriro akafanana neBP. Zvisinei, masayendisiti akawana kuti zviratidzo izvi zvinowanzoitika kune vatambi vanodzidzira bata mitambo kureba kana kuva nekukuvara kwakawanda mumusoro.
Kugona kuona zviri nyore zviratidzo zvekukuvara kwehuropi paMRIs kunogona kubatsira vanachiremba. Izvi zvingafarira chidzidzo uye kuonekwa kwekutanga kwekukuvara kunokonzerwa nemusoro.
Kudzokorora kunokanganisa kunowedzera kukuvara
Mabhenefiti anogona kuitwa nemitambo kune vechidiki zvikuru kupfuura chokwadi chekuti vanorova pasi pemamiriro akanyatso kudzora. Kazhinji, vatambi vetsiva vanogara vachiongororwa nachiremba uye kuongorora uropi, asi vamwe vangaramba.
Muchidzidzo ichi, masayendisiti akadzidza vanhu makumi manomwe neshanu vakafa avo vakasangana nekudzokororwa kwemusoro mukati mehupenyu hwavo uye vakabvuma kupa huropi hwavo kusainzi yekurapa mushure mekufa, paavhareji yemakore makumi matanhatu nematanhatu.
Mhedzisiro yacho inoratidza kuti chena nyaya hyperintensities inogona kubata kukuvadza kwenguva refu kuuropi muvanhu vane nhoroondo ye kudzokorora kurova mumusoro. MRI inogona kuve chishandiso chinoshanda chekudzidza mhedzisiro yekudzokororwa kwemusoro pachinhu chena chehuropi apo mutambi wetsiva achiri mupenyu.
Vatambi vacho vaive vatambi venhabvu vekuAmerica, vamwe vese vari vatambi vanobva mumitambo yekusangana yakaita setsiva kana nhabvu, kana varwi vehondo. Vesainzi vakatarisawo zvinyorwa zvemunhu ega-ega zvekurapa, kusanganisira kuvhenekwa muuropi kwaiitwa vanhu vachiri vapenyu, uye vakasangana nevadikani vavo kuti vaone kuti vanhu vari kurwara nedementia.
Zvichienderana nemhedzisiro yeautopsy, zvakatemwa kuti 71 muzana yezvidzidzo, vanhu makumi mashanu nevatatu mune vese, vaive nazvo chisingaperi chinoshungurudza encephalopathy, chirwere cheurourodegenerative chakabatana nekudzokororwa kunokanganisa musoro izvo zvinogona kutungamirira kuhurombo.
Vatambi vetsiva vechidiki vari panjodzi huru
Brain scans yakaratidza kuti kune yega yega mutsauko wehuwandu hwewhite matter hyperintensity, mikana yekuve nechirwere chetsinga diki uye kukuvadzwa kuchena kweuropi kwakawedzera kaviri.
Izvi zvakaperekedzwa nekuwedzera katatu mukana wekuva nea yakakura protein buildup tau mulobe yepamberi, budiriro inova biomarker yezvirwere zvakawanda zvehuropi zvinofambira mberi, kusanganisira chirwere cheAlzheimer.
Pakati pevatambi, kuve neakawanda chena nyaya hyperintensities inosanganiswa nemamwe makore etsiva uye mimwe mitambo yekusangana. Nekudaro, izvi zvine chekuita neakaipisisa zvibodzwa pamibvunzo yemibvunzo nezve kuomerwa mukuita mabasa ezuva nezuva.
