Mitsempha ya pakati ya ubongo imabweretsa oxygen ndi zakudya ku mbali za ubongo
Mitsempha ya pakatikati (yomwe imadziwikanso ndi MCA) ndiyo mitsuko yambiri yamagazi yomwe imabweretsa oksijeni ndi zakudya ku lobes, kutsogolo, ndi nyengo , pakati pa mbali zina zofunika za ubongo.
Pamunsi pa ubongo, mitsempha ya carotid ndi vertebrobasilar imapanga mzere wozungulira mitsempha yotchedwa Circle ya Willis. Kuchokera pa bwaloli, mitsempha ina - mitsempha yamakono ya m'mimba (ACA), mitsempha ya pakatikati ya ubongo (PCA) - ikani ndikuyenda kumadera onse a ubongo.
Mitsempha ya pakatikati ya ubongo ndi imodzi mwa zikopa zazikulu zomwe zimadziwika kwambiri. Kupha khunyu ndiko kuwonongeka kwa ubongo komwe kumachitika chifukwa cha kusokonezeka kwa magazi ku gawo lina la ubongo. Izi zimachitika chifukwa cha kutsekedwa kwa magazi kapena chotuluka m'magazi mu ubongo. Kachilombo kaŵirikaŵiri kamatchulidwa ndi mbali yovulala ya ubongo kapena chotengera cha magazi choletsedwa.
Kukwapula komwe kumakhudza ubongo wa pakati pa thupi limodzi kumayambitsa zofooka ( hemiplegia ) ndi kufooka pamaso, ndi / kapena mkono ndi / kapena mwendo kumbali ya thupi mosiyana ndi stroke.
Makhalidwe omwe MCA imaphatikizapo malo a Broca, malo olankhula bwino; Malo a Wernicke, malo olankhulana; galimoto yamoto, yomwe imayendetsa kayendetsedwe ka mutu, mutu,
thunthu ndi mkono; komanso korttex, yomwe imayendetsa mutu wa mutu, khosi, thunthu, ndi mkono.
Chifukwa chakuti mitsempha ya pakatikati ya ubongo imapweteka nthawi zambiri, kupuma kwa nthawi yaitali kumatha kutenga miyezi kapena zaka.
Komabe, ngakhale kukwapula kwakukulu kungabweretse bwino .
Kuchokera ku Middle Cerebral Artery Stroke
Munthu aliyense amene akudwala zida za pakati pa ubongo amakhala ndi nthawi yowonongeka yosiyana ndi kusowa kwa nthawi yaitali. Anthu ena adzapitirizabe kusintha masabata, miyezi kapena zaka pambuyo pa kugwedeza, kuganiza ndi kulankhula.
Pambuyo pa kupwetekedwa, anthu ena amavutika kupeza mawu kapena kulankhula zoposa mawu amodzi panthawi imodzi. Kapena, iwo sangathe kuyankhula nkomwe, omwe amatchedwa aphasia . Zitha kutenga zaka ziwiri kuti zibwezeretse bwino ndipo aliyense sadzachira.
