Kunezinhlobo eziningi ezihlukene kanye nezigaba zesifo sohlangothi. Izinhlobo zokushaywa komzimba zichazwa yizici ezimbili eziyinhloko-indawo yazo futhi ngenxa yengozi yomzimba ebuchosheni.
Isizathu Sokulimala Kwamathambo
Izibhamu zingabangelwa izici ezihlukahlukene. Ngokuvamile izimbangela zingasiza ukunquma ukubikezela kanye nendlela engcono yokwelapha. Ukushaywa isifo kungase kubangelwe ukuphazamiseka kwegazi kwe-clot egazini ebuchosheni, ngesitsha segazi esisuka ebuchosheni, noma ngokugeleza kwegazi okuphansi kuya esifundeni sobuchopho.
I-Blood Clot- Ischemia
I-stroke ebangelwa i-clot yegazi ibizwa ngokuthi i- ischemic stroke ngenxa yokuntuleka kwegazi, ngakho-ke i-oksijeni nezakhi ezibalulekile, esifundeni sezincubu zobuchopho. Isihlungu sokwe-ischemic singabangelwa yi-embolus, okuyi-blood clot ehamba ukusuka kwenye ingxenye yomzimba. Kungabangelwa i-thrombus, ngokuvamile ngenxa yesifo se- cerebrovascular . Noma, kungase kube umphumela we-vasospasm, ukwehlisa okungazelelwe kwesitsha segazi ebuchosheni.
Hemorrhagic
Ukwesulwa kwesitsha segazi ebuchosheni kubangela ukushaywa kwesifo esibi . Ngezinye izikhathi ukuphulukana kwe- aneurysm yobuchopho kubangela ukuphuma. Izinguquko ezishisayo ezingcindezini zegazi zingase zenze ukuqhuma kwe-aneurysm yobuchopho. Ngezinye izikhathi isifunda sobuchopho esonakaliswe yi-ischemia singagcoba phakathi kwezinsuku ezimbalwa zokuqala ngemva kokushaywa yisifo, okubangela ukubola kwesinye isikhathi.
I-stroke yamanzi
I-stroke ye-groundwater ibangelwa ukucindezelwa kwegazi okuphansi noma ukugeleza kwegazi okuphansi okwehlisela igazi ezindaweni ezingenakwenzeka zobuchopho.
I-stroke yamanzi angase ibe khona ezindaweni ezibuchopho ezihlinzekwa yimishanguzo emincane .
Indawo
Izigubhu nazo zichazwa indawo yazo ngoba ingxenye ethintekile yobuchopho ihambisana nokulahlekelwa okuthile okuphathelene negazi noma ukuziphatha.
I-stroke ye-cortical
I- cortic stroke ithinta i-cortex ye-cerebral, elawula ukucubungula izinga eliphezulu.
Izingxenye ezahlukene ze-cortex ye-cerebral zilawula imisebenzi ehlukene.
I-Frontal Cortex
Ukushaya kwesifo sangaphambili kubangelwa ukuhlukunyezwa kwemisipha ngakolunye uhlangothi lomzimba nezinkinga ngokuthatha izinqumo. Abantu abane-stroke ehlanganisa i-cortex yangaphambili bangabonisa ukuziphatha okungalungile komphakathi, i-paranoia noma bangase bavuselele ekuvuthweni. Ngezinye izikhathi, i- oss yesigqila noma isilonda singabangela.
I-Parietal Cortex
I-cortex ye-parietal ihilelekile ngokuhlanganiswa kokuzwela nolimi. Abantu abane-stroke ye-parietal ngokuvamile babonisa ukuzwela okungafaneleki noma inkinga ngokukhiqizwa kwenkulumo .
I-occipital cortex
I-cortex ye-occipital ihlanganisa umbono. Ukushaywa yisifo kulesi sifundazwe kungabangela ukulahlekelwa okuphelele noma okuncane kwombono ohlangothini oluhlukile lwesifunda se-occipital esithintekile.
I-cortex yesikhashana
I-cortex yesikhashana ibandakanyeka ngokuzwa nokukhuluma. Abantu abaye bahlaselwa isifo se-lobe besimanje banenkinga yokuqonda ulimi olubhalwe noma olukhulunywayo .
I-subcortical
I-stroke e-subcortical ithinta izifunda ezijulile zobuchopho.
IsiThalamic
Uhlangothi oluthile lwe-thalamic luvame ukubangela ukulahlekelwa okukhulu kwezinto ezibonakalayo ohlangothini oluhlukile lwezingxenye ezithile zomzimba, ngisho nalapho isifo sithinta isifunda esincane kakhulu sobuchopho.
I-capsule yangaphakathi
I-stroke echaphazela i-capsule yangaphakathi ingathinta imoto noma umsebenzi wezinzwa wezingxenye eyodwa noma ngaphezulu ohlangothini oluhlukile lomzimba.
I-Brainstem
I- brainstem stroke ingabangela izibonakaliso eziningi nezimpawu ezihlukahlukene. Kungabangela ubuthakathaka, izinguquko zengqondo, noma ukukhuluma ngenkinga. I-brainstem stroke ingathinta ukuhamba kohlangothi oluhlukile noma uhlangothi olufanayo lobuso noma umlomo. Abantu abanobuchopho be-brainstem bangase babe nenkinga ngokunyakaza kwamehlo, ngokuvamile okubonakala njengombono ophindwe kabili noma umbono obonakalayo. Ukwengeza, i-brainstem ilawula ukuphefumula futhi ilawula izinga lenhliziyo.
Ukulimala kwengqondo kungathinta imisebenzi ebalulekile, ngisho nalapho indawo encane ithintekile.
Isitsha segazi
Ezinye izichopho zibizwa ngokuthi yisitsha segazi esivinjelwe noma segazi.Isikhumba segazi esivame kakhulu esivinjelwe yi- artery central , okuyinto evame ukubangela ukushaywa okukhulu kwe-cortical okuthinta i-lobe yesikhashana ne-parietal.
