I-stroke inokuchaphazela nayiphi na inxalenye yengqondo. Xa enye yeemibhobho eziphambili ezinika igazi kwingqondo ikhutshwe, i- stroke ischemic can result, oku kuthetha ukuba indawo engaphiliyo yengqondo ayisekho imisebenzi njengoko kufanelekile.
Ummandla omkhulu wengqondo ubizwa ngokuba yi-cortex ye-cerebral. I-cortex ye-cerebral ihlukaniswe kwi-lobes emininzi, enemisebenzi eyahlukileyo kunye nokufumana igazi layo kwiimitha ezihlukeneyo.
Icala ngalinye (i-hemisphere) ye-cortex ye-cerebral ine-lobe yangaphambili, i-lobe yesikhashana, i-lobe ye-parietal kunye ne-lobe yama-occipital. Izibetho ezichaphazela enye okanye ngaphezulu kwe-lobes zengqondo zichazwa njengezibetho ze-cortical . Izibetho ze-Cortical ziba ziintlobo ezinkulu ngenxa yeendlela zemithambo yegazi kwingqondo. Iindidi ezahlukileyo zezibetho zengqondo zineempembelelo ezahlukileyo kwimisebenzi yomzimba kunye nokuziphatha kuba i-lobes eyahlukeneyo yengqondo nganye ineemisebenzi ekhethekileyo.
I-Lobe yangaphambili
I-lobe yangaphambili i-lobe enkulu kakhulu yengqondo. I-lobe yangaphambili ibandakanyeka ekulawuleni ukunyakaza komzimba. Kwakhona kubalulekile kwimemori, ukucinga, ukulungisa ingxaki nokugcina ukuziphatha okufanelekileyo.
I-frontal lobe isifo siphumela imiphumo emininzi, engabandakanya ubuthathaka kwelinye icala lomzimba, ukuguquka kokuziphatha, iingxaki zememori kunye neengxaki ngokuzinakekela.
Kunokuba nzima kakhulu kubaxhasi, amalungu omndeni kunye nabasindileyo bezilonda ukuba baphathe imiphumo yesifo sokuloba.
Ukuziqhelanisa nale mpawu kunokukunceda ukuba wamukele ezinye iinguqu ezenziwa ngabantu emva kokuphazamiseka kwe-lobe yangaphambili.
Abanye abasindileyo bezilonda ezinobunzima be-lobe bengazihlawulela . Oku kunokwenzeka ukuba ummandla wengqondo olawula ukunyakaza uchatshazelwa yi-stroke.
Iziganeko zeLobe
I-lobe yexesha elibalulekileyo ibaluleke kakhulu ekubhekiseni ulwimi, imemori kunye nokuva.
I-stroke ye-lobe yesikhashana ingabangela ingxaki ngokuthetha, okubizwa ngokuba yi-aphasia . Umsebenzi weelwimi ngokuyinhloko ufumaneka kwicala eliphambili leengqondo, okuyikhohlo elingasekhohlo yengqondo kubantu abanikezelweyo, kunye nekhohlo lokunene kwengqondo kubantu abaninzi abashiyekileyo. Ngako oko, i-stroke ye-lobe isifo sokunyuka kwexesha eliqhelekileyo sinokuvelisa i-aphasia xa kwenzeka kummandla ophezulu wengqondo.
Uhlobo oluthile lwe-aphasia olubangelwa uhla lwe-lobe lwe-lobe lubizwa ngokuba ngu-Broca's aphasia, kwaye lubonakalisa uhlobo oluthile lokuthetha olunzima ukuluqonda. Abasindileyo be-stroke abane-Broca's aphasia bahlala bakwazi ukufunda kwaye banokuqonda ukuba yintoni abanye abantu abakutshoyo. Abasindileyo be-stroke abane-Broca's aphasia banokucinga ngamagama alungileyo abafuna ukuthetha, kodwa abakwazi ukuvelisa loo mazwi. Abantu abaneBraca's aphasia banako ukuphucula ukuphuculwa kwentetho.
I-Loarial Lobe Strokes
I-lobe ye-lobes iyimimandla ebalulekileyo yengqondo ebaluleke kakhulu kwimbono yokuzimela, kunye nokukwazi ukuvakalelwa kwiindawo ezikuyo. I-parietal lobe stroke ingabangela ukulahlekelwa kwevakalelo ezichaphazela kwelinye icala lobuso, ingalo okanye umlenze.
I-lobe ye-parietal ikwabandakanyeka kumsebenzi wolwimi kunye nokucinga ngokuhlalutya.
I-parietal lobe stroke kwicala eliphambili leengqondo linokuvelisa i-aphasia. Uhlobo lwe-aphasia olubangelwa i-parietal lobe stroke kuthiwa i-Wernicke's aphasia. Abasindileyo be-stroke abanesifo sika-Wernicke's aphasia abakwazi ukusebenzisa amagama alungileyo xa bethetha kwaye kaninzi abayiqondi imisebenzi abanye abayithethayo. Ngamanye amaxesha, abasindileyo be-stroke abanama-aphasia aseWernicke bathetha ngokukhawuleza kwaye banomdla, kodwa bangena amagama angamazwi ngamagama angamazwi. Oku kunzima kakhulu kubahlali abasweleyo ababenama-aphasia ase-Wernicke ukuba bathathe inxaxheba ekuthatheni unyango.
I-parietal lobe stroke ivelisa utshintsho lombolo, lubangela ingxaki ngeengcinga zendawo, kunye neziphumo kwiingxaki zemisebenzi yemoto.
I-Occipital Lobe Strokes
I-lobes ye-occipital ibalulekile ekusebenzeni ngokubonakalayo. Ukuphazamiseka kwelo lophipital kungabangela ukulahleka kombono okanye ukulahlekelwa ngumbono kwelinye iliso okanye zombini amehlo.
Ngenxa yendlela indlela imivenge yegazi ehlelwe ngayo kwingqondo, i-occipital lobe izibetho aziqhelekanga kunezibetho ezichaphazela i-lobes yangaphambili, i-lobes temporal kunye ne-parietal lobes.
ILizwi
Ukuba wena okanye umthandayo unomdlavuza, unokuva ukubetha kwakho okuchazwe ngohlobo: mhlawumbi i- ischemic stroke (i-stroke ebangelwa ukucinywa komtshini kwindawo yobuchopho) okanye isifo esibuhlungu (isifo esibangelwa ukuphuma egazini ubuchopho.) Kungenzeka ukuba uvile ukubetha kwakho okuchazwe yindawo: nokuba yi- brainstro stroke , i-subcortical, lacunar, i-stroke encinci yesikhephe , okanye isitya esikhulu somkhumbi . Phakathi kwezi ziqendu, kukho ezinye iindidi ezithile zemivimbo. Ubuncedo bokukwazi ukuba yiyiphi uhlobo lokubetheka kwakho okanye wakho othandekayo uye waqamba amanga ngokwazi oko unokulindela xa uphila.
