Uthintelo lwe-Alzheimer kwiminyaka engamashumi amabini eyadlulayo!!

Uthintelo lwe-Alzheimer kwiminyaka engamashumi amabini eyadlulayo!!

Uphononongo olutsha kwiimpuku lufumene ukuba ukuveza ingqondo kwimisinga yombane kunokuthintela iimpawu zedementia ukuya kuthi ga kwiminyaka engama-20 ngaphambi kokuba zibonakale.

Ngokutsho kwephephandaba laseBritane elithi "Daily Mail", licaphula ijenali yezoNxibelelwano lweNdalo, olu phononongo lufumanise ukuba kunokwenzeka ukunqanda ukuwohloka kweeseli zengqondo kunye nokuthintela ukulahleka kwememori kunye nokuncipha kwengqondo ngokujolisa kwiindawo zobuchopho bempuku. yonakele ngexesha lesifo sika-Alzheimer.

Iminyaka engama-20 ngaphambi kokuxilongwa

Abaphandi baqhoboshela i-electrode yobude obuphantsi bomgangatho wamaza, ezaye zancanyathiselwa ngoqhaqho kwiimpuku zaselabhorethri, ukuthintela iiproteni eziyingozi ekubunjweni kwengqondo kunye neziko lememori yengqondo ukuba licuthe kanye ngenyanga.

Iziphumo zophando zibonise ukuba imisinga yombane ikhusela ukuwohloka okungaba ngumqondiso we-Alzheimer's disease, enokuthi ibe khona kwiminyaka eyi-10 ukuya kwe-20 ngaphambi kokuba isifo sifumaneke ebantwini.

Imeko yokulala

"Oku kubonisa ukuba kunokwenzeka ukuqikelela isifo kwimeko yokuxolelwa, ngaphambi kokuqala kokuncipha kwengqondo," watsho umphandi-uphando uDkt Ina Slutsky.

Uphononongo lubeke iliso kwiinguqu zengqondo ezenzeka ngexesha lokulala, ekukholelwa ukuba ziyenzeka rhoqo xa iimpawu zokuqala zemeko zivela, ngakumbi kwi-hippocampus, eyindawo yememori ebuchotsheni.

Iinkqubo ezilibazisa iimpawu

Umphandi ubonise ukuba "kukho iindlela ezihlawulela isifo esifanayo ngelixa sithe qwa, ngaloo ndlela sandise ixesha ngaphambi kokuba iimpawu zesi sifo zivele," njengoko iimpuku zaselabhoratri zafumana "ukuxhuzula okuthe cwaka" kwi-hippocampus ngexesha lokulala, okukhangeleka njengokuxhuzula xa kuhlolwa. Kodwa ke iimpuku ezisempilweni ziye zacutha umthambo, nto leyo ethetha ukuba ukuxhuzula okuthe cwaka kunokuba ziimpawu zokonakala kwengqondo.

Ukuvuselela ingqondo enzulu

Ukuthintela lo msebenzi ogqithisileyo, abaphandi basebenzisa ukuvuselela ingqondo enzulu (DBS), inkqubo yotyando apho i-electrodes ibekwe kwiindawo ezithile zobuchopho. Ezi electrode zidityaniswe ngeengcingo kwisixhobo esibekwe phantsi kwesikhumba kufutshane nesifuba.

Isixhobo sithumela iimpembelelo zombane nangaliphi na ixesha ingqondo ivelisa imiqondiso engaqhelekanga, efana naleyo ikhokelela kwinkumbulo kunye neengxaki zokulinganisa kunye nobunzima bokuthetha. I-DBS ikwasetyenziswa eUnited States ukunyanga izifo zemithambo-luvo ezifana nesifo sikaParkinson, ukuxhuzula, idystonia, kunye ne-obsessive-compulsive disorder.

Iimpawu eziqhelekileyo

Isifo i-Alzheimer's lolona hlobo luxhaphakileyo lwe-dementia, kwaye ligama le-ambrela elisetyenziselwa ukuchaza iqela leengxaki ze-neurological eziqhubekayo (ezo zichaphazela ingqondo), ezichaphazela imemori, ukucinga kunye nokuziphatha.

Iimpawu eziqhelekileyo zibandakanya ukulahleka kwememori, ukugweba kakubi, ukudideka, imibuzo ephindaphindiweyo, ubunzima bokunxibelelana, ukuthatha ixesha elide ukugqiba imisebenzi eqhelekileyo yemihla ngemihla, ukwenza ngokungakhathali, kunye neengxaki zokuhamba.
