Uphononongo olude olulandelelweyo lweqela lubonisa ukuba ukulahleka kwezivamvo zokujoja kunokuba sisiqalo sakwangoko impilo iingxaki kunye nokufa okuphezulu phakathi kwabantu abadala
Kuyaziwa ukuba njengoko sikhula izivamvo zethu ziqala ukwehla kubandakanya ukubona, ukuva kunye kananjalo imvakalelo yevumba. Uphononongo lubonise ukuba ukungaqondi kakuhle livumba luphawu lokuqala lwe Isifo sikaParkinson, isifo sengqondo esiyingozi kwaye sikwayanyaniswa nayo ukuhla ukusinda. Nangona kunjalo, ezi zifundo zithintelwe bubude bexesha kunye nokungabikho kokulandelayo. Ikhonkco phakathi kokuziva kakubi kwevumba kunye neziphumo zempilo ezingalunganga azikaqiniswa kakuhle. Uphononongo olutsha olupapashwe kwi Amanqaku angamayeza angaphakathi ngo-Epreli 29 ejolise ukuvavanya ubudlelwane phakathi kolu kusilela kweemvakalelo kunye nokufa okuphezulu kubantu abadala.
Kuphononongo lwangoku lweqela elisekelwe kuluntu, abaphandi basebenzise idatha evela kwiZiko leSizwe lokuguga e-USA 'isifundo se-ABCD sezeMpilo. Bavavanya ulwazi kwisithuba seminyaka eyi-13 ukusuka malunga ne-2,300 yabathathi-nxaxheba abadala abadala kuquka amadoda kunye nabasetyhini bemvelaphi eyahlukeneyo yobuhlanga (abamhlophe nabamnyama) ababephakathi kweminyaka eyi-71 kunye ne-82. Ulwazi luqokelelwe kwiimvavanyo zokuchongwa kwevumba le-12 yevumba eliqhelekileyo. kubandakanywa nesinamon, ilamuni kunye nomsi. Ngokusekelwe kolu lwazi abathathi-nxaxheba bahlelwa njengabalungileyo (b) abaphakathi okanye (c) abaziva kakubi ngokujoja. Iziphumo zempilo kunye nokusinda kwabathathi-nxaxheba zaye zalandelwa kwi-3, i-5, i-10 kunye ne-13 iminyaka emva kokuqala kophando kubandakanywa nokuhlolwa kweefowuni.
Uphononongo lubonise ukuba xa kuthelekiswa nabantu abadala abaziva kakuhle ukujoja, abantu abangeva kakuhle ukujoja babene-46 yeepesenti ephezulu yomngcipheko wokufa phakathi kweminyaka eli-10 kunye ne-30 yepesenti yomngcipheko ophezulu kwiminyaka eli-13. Iziphumo zathathwa njengezingakhethi cala njengoko ubukhulu becala bezingachatshazelwanga sisini, uhlanga okanye indlela yokuphila. Ngaphezu koko, abathathi-nxaxheba ababesempilweni ekuqaleni kophononongo baba nemingcipheko ephezulu. Ukusweleka okuphezulu kwabalelwa kukuphazamiseka kwe-neurodeergenerative (efana ne-dementia) kunye nokuncipha kobunzima kunye nezifo zentliziyo. Izigulo zokuphefumla okanye umhlaza azikhange zibonwe zinxulunyaniswa nokulahlekelwa luvo lokujoja.
Uphononongo lwangoku lubonisa ukuba phakathi kwabantu abadala abadala, ukuba nemvakalelo yokuvumba engalunganga kubonisa phantse i-50 yepesenti yomngcipheko ongaphezulu okanye amathuba okufa kwiminyaka eli-10. Oku kwakuyinyaniso nakubantu abasempilweni ababengenazigulo okanye iingxaki zempilo. Ke, ukungaziva kakuhle kwevumba kunokuba sisilumkiso kwangethuba sempilo enkenenkene ngaphambi kokuba kuvele ezinye iimpawu okanye iimpawu zesigulo. Omnye umda wophononongo ngumba wokuba olu lungelelwaniso lubalele kuphela malunga neepesenti ezingama-30 iimeko zokufa okwandisiweyo phakathi kwabathathi-nxaxheba. Kwiipesenti ezingama-70 eziseleyo zeziganeko zokufa okuphezulu azicacanga kwaye zinokunxulumana kakhulu nemiba yempilo engapheliyo. Nangona kunjalo, kucetyiswa ukuba imvakalelo yokuhlola ivumba okanye iimvavanyo zokuvumba kufuneka zibandakanywe kuhlolo lwesiqhelo lwabantu abadala kunye novavanyo lwemigangatho olwenziweyo ngoku lweempawu ezibalulekileyo, ukuva kunye nokubona. Olu phononongo lucacisa unxibelelwano olunokwenzeka phakathi koluvo lwevumba kunye nokufa kwaye lufuna uphononongo olongezelelweyo.
