I-lobe ye-occipital iyindawo engemva kwengqondo edlala indima enkulu ekuhlanganiseni umbono wethu, esivumela ukuba siqaphele futhi sibe nomqondo walokho amehlo ethu akubona.
I-occipital lobe stroke ngokuyinhloko ihlotshaniswa nezinguquko embonweni. Igazi elihlinzekwa lobe wesipilitini liholela kwezinye izici eziyingqayizivele zemivimbo ye-lobe yemvelo:
- Ngokungafani nemivimbo eminingi esithinta ngaso sonke isikhathi uhlangothi olulodwa lobuchopho, isifo sofuba se-lobe singasithinta omunye noma kokubili lo-occipital lobes.
- Ngokuvamile, ukushaywa kwe-occipital lobe kungavamile uma kuqhathaniswa nemivimbo ethinta enye i-lobes yobuchopho (yangaphambili, i- parietal kanye nesikhashana.)
Imiphumela ye-Occipital Lobe Stroke
I-occipital lobe stroke ingabangela izinguquko ezihlukahlukene ezibukwayo, ezibandakanya ukulahleka kombono, ukuphutha okuphelele kanye nokuboniswa kwezinto ezibukwayo, kanye namanye ama-syndromes abukwayo abukwayo. I-loip occipital ayifani ngokuphelele, futhi izifunda ngaphakathi kwe-lobe occipital zidlala indima ehlukene ekuhlanganiseni umbono. Izinkinga ezihlukahlukene ezibukwayo ezingabangelwa isifo sofuba se-occipital sincike kunoma yisiphi isifunda ngaphakathi kwe-lobe yesipilili esithintekile.
Izinguquko Ebonakalayo Ngemva Kwesifo Se-Lobe Sase-Occipital
- I-Hemanopia yamaHomonomous- I-Stroke ethinta i-Lobe yama-Occipital e-One Side
Lapho lesi sifo sithinta iningi lobe wesipiliyoni ohlangothini olulodwa lobuchopho, inkinga ebonakalayo evelayo ibizwa ngokuthi i- hemianopia engaziwa ngamuntu . Lokhu kuchaza ukulahlekelwa kwesigamu sombono esweni ngalinye.
Umsindisi olwa nesifo sofuba onesizwe esingenalo i-hemianopia akakwazi ukubona izinto eziphambene nalesi sifo.
I-stroke echaphazela i-lobe yesandla esesobunxele engokwesobunxele ingabangela ukuba umsindisi olwa nesifo sohlangothi abe nobunzima ukubona izinto ngakwesokudla. Le nkinga iyakuthinta kokubili amehlo-okusho ukuthi umuntu akakwazi ukubona ohlangothini olungakwesokudla kweso elungile futhi akakwazi ukubona ohlangothini olungakwesokunxele ngeso lesobunxele.
Ngokuvamile, i-hemianopia engazihloniphi igama ayihambisani ngokuphelele, njengoba ukuhlanganiswa okubukwayo emehlweni kungase kungathinteki ngokulinganayo ngesifo.
- I-Central Vision Defect-Stroke Ethinta Isiqu Semvelo
I-poipitalital pole yisendaweni yobuchopho lapho umbono ophakathi uqhutshwa khona. Umbono ophakathi uchaza lokho okubonayo enkabeni yensimu yakho ebonakalayo uma ubheka phambili phambili. Ngakho-ke, isifo esithinta isigxobo se-occipital singakusiza ukuba ube nendawo enkulu eyimpumputhe phakathi kwendawo yakho ebonakalayo ohlangothini oluthintekile.
Umuntu onenkinga yangaphakathi yombono obangelwa ukushaywa kwesigxobo se-occipital angenandaba nokubona ubuso bomuntu obemi ngokuqondile kuye. Isibonelo, osindile wesitofu angeke akwazi ukubona ikhala lomuntu, i-lip eliphezulu, nengxenye engezansi yeso ohlangothini oluthintekile, kodwa uzokwazi ukubona ihlombe lomuntu kanye nekhanda laphezulu.
Izigameko ze-Occipital ziyinto engavamile.
- Ukuphulukisa Amakhambi - Ukushaywa Isifo Ukuthinta I-Lobes Ye-Occipital Kokubili
Uma lobes occipital yobuchopho zithinteka ngokuphelele isifo, umphumela wokuphela kuyinto into ebizwa ngokuthi "ukuphuphuthekisa cortical." Lokhu kufana nalokho esikuqonda sonke igama elithi "ukuphuphuthekisa," kodwa leli gama lisetshenziswa lapho umonakalo i-cortex yobuchopho yimbangela yokuphuphuthekisa.
Kunezibonakaliso eziningana zokuphuphutheka kwe-cortical ngaphezu kokulahlekelwa umbono. Abanye abasindile isifo sokuqwashisa bayazi ukuthi abakwazi ukubona, kanti abanye abasindile ngengozi abaqapheli ukuphuphuthekisa kanye nokuhlangenwe nakho okubonwayo. I-syndromes echazwe kahle kakhulu ekhonjiswe ukuphuphutheka kwama-cortical kanye nama-corucination ehlotshaniswayo ebizwa ngokuthi i- Anton syndrome ne-Balint syndrome.
Abanye abasindile be-occipital bahlushwa ngesimo esibizwa ngokuthi i-visual anosognosia, esibhekwa ngokunganaki ingxenye eyodwa yombono.
- Ezinye Ezinye Izimpawu / Ama-Syndromes Ahlanganiswe Nokushaywa Kwe-Occipital
- I-Visual Illusions
- Ama-Hallucinations okubukwayo
- Ama- Agnosias okubukwayo
- I-Prosopagnosia
- U-Alexia ngaphandle kwe-Agraphia
Yini Ebangela Ukushaywa Kwe-Loip Occipital?
Imishanguzo egijima ngemuva kwentamo, ebizwa ngokuthi imishanguzo ye-vertebral, imishanguzo ye-cerebral posterior kanye ne-basilar arteries, ihlinzeka ngegazi okwenziwe nge-oksijini e-occipital lobes. Uma omunye noma kokubili i-occipital lobes ihlangabezana nokuphazamiseka kwegazi, khona-ke imiphumela yesifo.
I-Occipital lobe imivimbo ingavamile ngenxa yokuthi igazi elinikezwa i-loip occipital lihlelwe ngendlela ehlukile. Imishanguzo ye-vertebral, imishanguzo ye-cerebral posterior kanye nemithambo ye-basilar ehlinzeka igazi ngemuva kwengqondo, ixhumane nomunye ezindaweni ezithile, okuvumela ukuba banikeze igazi eliphindwe kabili, ngokuvamile bahlawulane. Leli lungiselelo livame ukuvikela ukulwa nemivimbo ezindaweni ezingemuva kwengqondo lapho ukugeleza komunye umthamo omncane kuvinjelwe- ngoba elinye isitha linganikeza ukugeleza kwegazi okwanele.
Ngenxa yelungiselelo lemithambo yegazi elinikezela i-lobe ye-occipital, ngezinye izikhathi isifo sofuba se-occipital sihambisana nesifo socerebellar noma isifo se- brainstem .
Izwi elivela
Ukushaya isifo kungabangela ushintsho olukhulu embonweni, kuhlanganise nokulahleka kombono, izinguquko embonweni kanye namaphethini angavamile embonweni.
Akuwona wonke ushintsho lombono owenziwe ngengozi olubangelwa ukushaywa kwe-occipital lobe, njengoba imivimbo kwezinye izifunda zobuchopho kungabangela nezinguquko zombono . Izinguquko embonweni ngemuva kokushaya isifo zingathinta kakhulu indlela yokuphila, ikakhulu uma kuziwa ekushayweni ngemuva kokushaywa yisifo.
Uma ubona izimpawu ezibukwayo, kufanele ufune usizo lwezokwelapha ngokushesha, njengoba izinguquko zombono zingase zibe uphawu lokuqala lwezinkinga ezinkulu zezokwelapha, njenge-stroke.
