Kukho iintlobo ezahlukeneyo kunye neendidi zesifo. Iintlobo zokubetha zichazwa ziimpawu ezimbini eziphambili-indawo yazo kunye nesizathu somonakalo wesisu kwindawo yengqondo.
Isizathu Sokulimala kweTishu
Izibetho zibangelwa ziintlobo ezahlukeneyo. Ngokuqhelekileyo izizathu zinganceda ukucacisa ukuxilongwa kunye nendlela efanelekileyo yokunyango. I-stroke ingabangela ukuphuma kwegazi eliphazamisayo ukuphazamiseka kwegazi kwingqondo, ngesitya segazi esigazileyo kwingqondo, okanye ngegazi eliphantsi kwegazi ukuya kwingingqi yengqondo.
I-Blood Clot- Ischemia
Ukubetha okubangelwa yi-clot yegazi kuthiwa yi- ischemic stroke ngenxa yokungabikho kwegazi, kwaye ngaloo ndlela i-oksijini kunye nezondlo ezibalulekileyo, kummandla weengxube zengqondo. I-stroke ye-ischemic ingabangelwa yi-embolus, egazini legazi elihamba kwelinye inxalenye yomzimba. Ingabangela i-thrombus, ngokuqhelekileyo ngenxa yesifo se- cerebrovascular . Okanye, kusenokuba sisiphumo sevasospasm, ukunqumla ngokukhawuleza kwesitya segazi kwingqondo.
Hemorrhagic
Ukuhlambuluka kwesitya segazi kwindawo yobuchopho kubangela ukushaya kwesifo esibi . Ngamanye amaxesha ukuphuka kwengqondo enesinvirysm kubangela ukuphaphaka. Utshintsho olunzulu kwixinzelelo lwegazi lunokubangela ukugqithwa kwengqondo enesifo. Ngamanye amaxesha ummandla wengqondo owonakaliswe yi-ischemia inokuphuma igazi emva kweentsuku ezimbalwa emva kokuphazamiseka, okubangela ukuba i-stroke yesibini.
Kuphazamiseka kwamanzi
Uphazamiseko lwamanzi lubangelwa ngumxhesho ophantsi wegazi okanye ukuhamba kwegazi okuphantsi okuphazamisa ukunikezelwa kwegazi kwiindawo ezikhuselekileyo zobuchopho.
Uphahla olumanzi luya kwenzeka kwimimandla yengqondo ehlinzekwa yimibhobho emincinci .
Indawo
Izibetho zichazwe kwakhona ngendawo yazo ngenxa yokuba inxalenye echaphazelekayo yengqondo ihambelana nokulahlekelwa kweengqondo okanye zokuziphatha.
I-stroke ye-Cortical
I- stroke ye-cortical ichaphazela i-cortex ye-cerebral, elawula ukusetyenziswa kwezinga eliphezulu.
Iindawo ezihlukeneyo ze-cortex zilawula imisebenzi ehlukeneyo.
Frontal Cortex
I-stroke yangaphambili ye-lobe ibangela ukuba ubuthathaka bubuhlungu kumacala omzimba kunye nenkathazo ngokuthatha izigqibo. Abantu abane-stroke ezibandakanya i-cortex yangaphambili bangabonakalisa ukuziphatha ngendlela engalunganga, i-paranoia okanye i-regress in mature. Ngamanye amaxesha, i- oss ye-bladder okanye yokulawula isisu ingabangela.
IParietal Cortex
I-cortex ye-parietali ibandakanyeka ngokudibanisa uvakalelo nolwimi. Abantu abane-stroke ye-pariet often babonisa ukungahambi kakuhle okanye inkathazo ngemveliso yentetho .
Occipital cortex
I-cortix ye-occipital idibanisa umbono. Ukuphazamiseka kule ndawo kungabangela ukulahlekelwa okupheleleyo okanye okukodwa kwembono kwicala eliphambene naloo ndawo.
Cortex yesikhashana
I-cortex yesikhashana ibandakanyeka ngokuva kunye nolwimi. Abantu abaye bafumana ukubetha kwe-lobe kwangexesha eliqhelekileyo banenkxalabo yokuqonda ukubhala okanye ukuthetha ulwimi .
I-subcortical
I-stroke ehambelana ne-subcortical ichaphazela imimandla enzulu yengqondo.
Thalamic
I-thalamic stroke ivame ukudala ukungaphumeleli okukhulu kwintlupheko kwicala elinye okanye amaninzi emzimbeni, nangona xa isithintelo sichaphazela ummandla omncinci wengqondo.
I capsule yangaphakathi
I-stroke echaphazela i-capsule yangaphakathi inokuphazamisa umsebenzi okanye isenzo senzwa yesinye okanye ezinye iinxalenye zecala elincinane lomzimba.
Brainstem
I- brainstro stroke ingabangela iintlobo neempawu ezininzi. Kungabangela ubuthathaka, utshintsho lweengqondo, okanye ingxaki yokuthetha. I-brainstro stroke inokuphazamisa ukuhamba kwecala okanye icala elinye lobuso okanye umlomo. Abantu abafumana isifo sengqondo seengqondo bangenenkathazo yokunyuka kwemehlo, edla ngokubonakala njengombono ombini okanye umbono obonakalayo. Ukongezelela, i-brainstem ilawula ukuphefumula kwaye ilawula izinga lentliziyo.
I-brainstro stroke inokuchaphazela imisebenzi ebalulekileyo, nangona indawo encinci ichaphazelekayo.
Ivazi yegazi
Ezinye izibetho zibizwa ngokuba ngumthi wegazi ovalwe okanye uphephayo. Isixhobo segazi esivame ukuchithwa ngokugqithisileyo sisisitja sombindi esisisiseko esiphambili, esibangela ukuba kuqhutywe i-corroke enkulu ye-corroke echaphazela i-lobe ne-parietal lobes.
