I-lobe ye-occipital yindawo engemva kwengqondo edlala indima enkulu ekudibaniseni umbono wethu, esivumela ukuba siqaphele kwaye siyibone ingqalelo kwamehlo ethu.
I-stroke ye-lopipital i-lobe ngokuyinhloko ihambelana neenguqu kwimibono. Ukunikezelwa kwegazi kwi-lop occitalital lobe kubangela ezinye iimpawu ezikhethileyo zokubethelwa kwemilingo yamagumbi:
- Ngokungafani neentlobo ezininzi eziphantse zithintela kwelinye icala lobuchopho, isifo se-loph occiptal sitshintshe enye okanye zombini i-lopital lobes.
- Ngokuqhelekileyo, ukubetha kwe-occipital lobe akuqhelekanga kuqhathaniswa nemivimbo echaphazela enye i-lobes yengqondo (yangaphambili, i- parietal kunye nexesha lexesha.)
Iimpembelelo ze-Lop Stroke
I-stroke ye-occipital i-lobe ingabangela ukutshintsha kweembonakalo ezahlukeneyo, ezibandakanya ukulahleka kombono, ukuphefumula okupheleleyo kunye nemiboniso ebonakalayo kunye namanye ama-syndromes ahlukeneyo. I-lobe ye-occipital ayifani ngokupheleleyo, kwaye imimandla ngaphakathi kwe-lobe yama-occipital idlala indima eyahlukeneyo ekudibaniseni umbono. Iingxaki ezibonakalayo ezahlukahlukeneyo ezinokubangela ukuhlaselwa kwe-lopitalital lobe kuxhomekeka kuyo nayiphi indawo ngaphakathi kwelo lopilital echaphazelekayo.
Iinguqulelo ezibonakalayo emva kwe-Lobe Stroke yama-Occipital
- Homonomous Hemianopia- Ulwaphulo oluchaphazela i-Lobe yama-Occipital kwi-One Side
Xa i-stroke ithinta ininzi yelobe ye-occipital kwelinye icala lobuchopho, ingxaki ebonakalayo ivela kuthiwa yi- homemia ye-hemianopia . Oku kuchaza ukulahlekelwa kwisiqingatha sombono kweso ngalinye.
Umntu osindayo onokuqhaqhaqhaqhazelayo onokuzibiza nge-hemianopia akakwazi ukubona izinto eziphambene noluhlu.
I-stroke echaphazela i-lobe yama-occipital ye-brain iyakubangela ukuba umntu osindayo abe nobunzima ukubona izinto kwicala lasekunene. Le ngxaki ichaphazela amehlo onke-oku kuthetha ukuba umntu akakwazi ukubona kwicala lasekunene kwiso elisekunene kwaye akakwazi ukubona kwicala lasekunene kwiso lasekhohlo.
Ngokuqhelekileyo, i-hemianopia engabonakaliyo ngamagama ayifani ngokulinganayo, njengoko ukubonisana okubonakalayo kwamehlo kungabandakanyeki ngokulinganayo.
- Umbono oMbindi weCandelo eliPhephekileyo-Ulwaphulo oluchaphazela iPolitical Pole
Ipolipital ipolisi yindawo yengqondo apho iphambili yombono iqhutyelwa khona. Umbono oMbindi uchaza oko ubona kwinqanaba lembonakalo yakho xa ubheka phambili phambili. Ngako oko, uhlangothi oluchaphazela ipiliti ye-occipital luya kukubangela ukuba ube nebala elikhulu ephosakeleyo phakathi kwendawo yakho yokujonga kwicala elichaphazelekayo.
Umntu onomdaka ophakathi kombango obangelwa ukubethelwa kwesigxina se-occipital kuya kunzima ukubona ubuso bomntu obemi ngqo kuye. Ngokomzekelo, umsindisi osiswini angeke akwazi ukubona umphunga womntu, umlomo ophezulu kunye nesigxina esingaphantsi kweso kwicala elichaphazelekayo, kodwa uya kukwazi ukubona umgca womntu kunye nentloko yentloko.
Izibonda ze-Occipital ziyinto inqabile.
- Ukukhunjulwa Kwe-Cortical- Ulwaphulo oluchaphazela iiLobes ze-Occipital kuzo zombini
Xa i-lobes yes occipital echaphazelekayo yintlungu, isiphumo siphumo sichazwa ngokuba yi-"cortical blindness". Oku kufana noko sonke siyiqonda ngegama elithi "ukungaboni," kodwa eli gama lisetyenziswe xa umonakalo I-cortex yengqondo yimbangela yokungaboni.
Kukho iimpawu ezininzi zobungqina bobuqhetseba ngaphezu kokulahlekelwa kombono. Abanye abasindileyo besifo bayazi ukuba abanakuzibona, ngelixa abanye abasindileyo bengazi kakuhle ukungaboni kunye namava okubona. I-syndromes echazwe kakuhle kakhulu ebonakaliswe yimfama yokuzibona kunye ne-hallucinations ebonakalayo ebizwa ngokuba yi- Anton syndrome kunye ne-Balint syndrome.
Abanye abasindayo be-occipital bahlushwa yimeko ebizwa ngokuthi i-visual anosognosia, ebonakalayo ngokunyanzeliswa kwelinye icala lombono.
- Ezinye iziMpawu / iiSyndromes eziHlanganisiweyo neSpipital Stroke
- Visual Illusions
- I-Visual Hallucinations
- Agnosias ebonakalayo
- Prosopagnosia
- Alexia ngaphandle kweAgraphia
Yintoni eyenza i-Occipital Lobe Stroke?
Iimitha ezisebenza ngaphaya kwentamo, ezibizwa ngokuba yimithambo ye-vertebral, i-artery fetries, kunye ne-basilar arteries, inikezela ngegazi oksijini kwi-lobes occipital. Ukuba enye okanye zombini i-lops occipital ihlangabezana nokuphazamiseka kwegazi, ngoko kuphazamiseka kwe-stroke.
Izigulane ze-Lop Occital aziqhelekanga kuba igazi le-lobe ye-occipital lihlelwe ngendlela ekhethekileyo. Imithambo ye-vertebral, i-arterial arteries, kunye nemibhobho ye-basilar eyenza igazi kumqolo wengqondo, idibanisa nomnye kwezinye iindawo, ezivumela ukuba banikezele ngegazi ngokuphindaphindiweyo, bahlala behlawulelana. Eli lungiselelo lisebenza ngokubanzi ukukhusela ngokuchasene nemimandla kwimimandla engemva kwengqondo xa ukuqhutyelwa kombhobho othile omncinci kuphazamiseka-kuba omnye umzobo unganika ukuhamba kwegazi okwaneleyo.
Ngenxa yelungiselelo lemithambo yegazi ehambisa i-lobe yama-occipital, ngamanye amaxesha i-lopistital lobe isifo somoya sihamba kunye nesifo se- cerebellar okanye i- brainstro stroke .
ILizwi
Ukuphazamiseka kunokubangela ukuba utshintsho olukhulu kumbono, kubandakanywa ukulahleka kombono, utshintsho kwimboniso kunye neendlela eziqhelekileyo zombono.
Akunjalo yonke inguqu yombono oguqulwayo obangelwa ngumonakalo we-occipital lobe, njengemivimbo eminye imimandla yengqondo inokubangela ukuba utshintsho lwombono lube nako . Utshintsho kumbono emva kokuphazamiseka lunokuba nefuthe elikhulu ekusebenzeni kwendlela yokuphila, ngakumbi xa kuvela ekuqhubeni emva kokuphazamiseka.
Ukuba ufumana iimpawu ezibonakalayo, kufuneka ufune unyango ngokukhawuleza, njengoko utshintsho lomboniso lube ngumqondiso wokuqala weengxaki zempilo ezinjenge-stroke.
