Kungani Ingxenye Yomzimba YeBrain Ethintwe Yizindaba Ze-Dementia
Zonke izinhlobo ze-dementia, eyaziwa ngokuthi yi-major disorder disorder, zibangela ukukhubazeka ememori, ukucabanga, nokwahlulela . Kuye ngokuthi yiyiphi ingxenye yobuchopho obhekwa njengendawo eyinhloko yokwehla kwesifo sengqondo somqondo, uhlobo lokuwohloka komqondo lungase luhlukaniswe njenge-cortical noma subcortical. I-cortical ne-subcortical ibhekisela ezindaweni zobuchopho.
I-Cortical noma i-Subcortical?
Ngenkathi abanye odokotela bengasebenzisi lezi zigaba ze-cortical noma subcortical njalo, abanye bathola ukubaluleka kokuhlukanisa izinhlobo ze-dementia kulezi zinhlangano ngokususelwa endaweni yokuqala yokulimala ebuchosheni.
Noma ngabe iyiphi indawo yobuchopho (cortical noma subcortical) ethintekayo ngokuvamile izobonisa izinguquko ezingokwenyama ekuqaleni, njenge- atrophy (shrinkage) . Kodwa-ke, njengoba ukuwohloka komqondo kuqhubekela phambili, izimpawu nemiphumela yazo zonke izigaba zokuhlukumeza komqondo ziqala ukuphazamisa izindawo eziningi zobuchopho.
Ngokuvamile, ukuhlukaniswa kwe-dementia njenge-cortical noma i-subcortical akusizi kakhulu kunalokho okwenzeni uhlobo oluthile lwesifo somqondo okhona. Lokhu kungenxa yokuthi uhlobo ngalunye lwe-dementia lunezici zalo ezilindelekile, izimpawu, nokubikezela.
I-Cortical Dementia ichazwe
I-cortex yobuchopho (igama cortical libhekisela ku-cortex) yingxenye yabantu abaningi abajwayele, okungenani uma kuziwa ekubukeni. Isici esiphendukayo futhi siphenduka sezingxenye zangaphandle sidlala indima ebalulekile ekucubunguleni ulwazi kanye nemisebenzi efana nolwimi nememori .
Ukuwohloka komqondo komqondo okuxubile kuhlotshaniswa nendaba yobuchopho obuchopho.
Lapho lezi zingxenye zangaphandle zithintekile, okuyinto enesifo sokuwohloka komqondo kwe- Alzheimer's , frontal demoral , isifo se-Binswanger nesifo se- Creutzfeldt-Jakob , kunezinkinga ngenkumbulo, ukungakwazi ukuthola amagama afanele , nokuqonda okushiwo abanye (aphasia).
I-Dementia ecacile echazwe
Njengoba leli gama libonisa, lezi zingu-dementias ezikholelwa ukuthi ekuqaleni zithinta izakhi ezingezansi kwe-cortex (ngezansi izindlela ezingezansi) futhi zihlotshaniswa nezindaba ezimhlophe zobuchopho.
Isifo sikaHuntington , ukucindezeleka kukaParkinson , nokuxilongwa kwengqondo ye- AIDS yizibonelo ezintathu zezimo ezihlukaniswa njengokungazinzi komqondo.
Kuvame ukubona ukuguqulwa kobuntu nokunciphisa izinqubo zokucabangela ekumenikeni komqondo ongaphansi kwamandla. Imisebenzi kanye nemisebenzi yememori ngokuvamile ibonakala ingabonakali kakhulu ezinyathelweni zangaphambili zale dementias.
Ukwelashwa Nokuphathwa
Ukwelashwa nokuphathwa komqondo wokugula komqondo ngokuvamile kuye kwagxila kakhulu esibhedlela i-Alzheimer ngoba kuyimbangela ejwayelekile kunazo zonke yokudemuka kwengqondo. Lezi imithi ngezinye izikhathi zisetshenziselwa ukuphatha ezinye izinhlobo ze-dementia kanye, nakuba zivunyelwe i-FDA ikakhulukazi i-Alzheimer's.
Izindlela ezingezona izidakamizwa nazo zingasiza ekunakekeleni ukugula komqondo. Ukuzivocavoca umzimba , ukudla , nokusebenza kwengqondo konke kubonise izinzuzo ekucwaningweni kulabo abaphila ne-dementias ehlukahlukene, kungaba ama-cortical noma ama-subcortical.
Isibikezelo
Ukuchazwa kwe-dementia ye-cortical ne-subcortical kuyahluka kakhulu. Izinhlobo eziningana zokuhlukumezeka kwengqondo ziwela kulezi zigaba, futhi ukuthuthuka kuthinteka yizici eziningi. Ukuqala kokuqala, impilo ejwayelekile kanye nezinye izinselelo zezokwelapha zingathinta ukubikezela nokuphila kwesikhathi.
