Mayankho a 'Kodi Stroke Ndi Chiyani?' 'N'chiyani Chimachititsa Stroke?' ndi zina
Mwamvapo mawuwo mobwereza bwereza koma mukudabwabe: Kodi sitiroko ndi yotani? Stroke ndi kupweteka mwadzidzidzi mu ubongo kugwira ntchito. Wina amatha kuvutika kulankhula kapena kulankhula momveka bwino, kuyenda, kapena kusuntha chiwalo chifukwa magazi asiya kuyenda kumalo a ubongo. Kawirikawiri, izi zimayambitsidwa ndi kutseka kwa magazi.
Mosiyana ndi mautumiki, omwe amadziwikanso kuti masoka a ischemic omwe amatha nthawi yayitali (TIA) , omwe zizindikiro zawo zimasankha okha mwa maola osachepera 24, zikwapu zimachokera ku zovuta zokhudzana ndi matenda a ubongo.
Kuopsa kwa zovuta izi kumadalira ubongo ndi ubongo, komanso ubongo umene umakhudza.
Kodi mitundu yosiyanasiyana ya sitiroko ndi yotani?
Pali magulu awiri akuluakulu a kupweteka: ischemic ndi magazi.
Mtundu woterewu umayamba chifukwa cha kuthamanga kwa magazi kumalo a ubongo. Mitundu yowonjezereka ya sitiroko ischemic ndi:
1) Embolic Stroke
Mtundu woterewu umachitika pamene magazi amagazi kapena cholesterol amathamangira mu ubongo kufikira atafika pamphepete mwachindunji kumene umakhala wotsekedwa. Izi zimapangitsa kuti magazi asasokonezeke komanso kuti magazi asafike ku gawo la ubongo. Pali zina zomwe zimayambitsa zikwapu zomwe zimaphatikizapo:
2) kupweteka kwapweteka
Mu mtundu uwu wa stroke mawonekedwe amagazi a magazi mkati mwa mchere wa magazi omwe amachititsa kusokonezeka kwa magazi kutuluka kumalo a ubongo.
Mitsempha yamagazi, yomwe imatchedwanso thrombus, nthawi zambiri imakhudza mitsempha yaing'ono yamagazi mu ubongo, makamaka kwa anthu omwe ali ndi cholesterol.
Makhalidwe Abwino a Cholesterol
Chifukwa mitsempha yaing'ono ya ubongo imabweretsa magazi ku magawo ang'onoang'ono a ubongo, zilonda zapwetekiti zimakhala zochepa, ndipo nthawi zina zimatchedwa kuti lacunar .
Komabe nthawi zina, magazi ambiri amatha kukhala mkati mwa mitsempha yambiri yamagazi m'khosi, ndipo kenako amasiya kupweteka kwambiri .
Matenda otentha
Mtundu woterewu umachitika pamene chombo cha magazi mkati mwa ubongo chimasokonekera, zomwe zimalola kuti magazi alowe mkati kapena pafupi ndi ubongo wabwino. Nthaŵi zambiri, izi ndi zotsatira za kuthamanga kwa magazi kosalamulirika.
Malinga ndi malo omwe amachotsa magazi, kupwetekedwa kwa magazi kumagawidwa
- Kuchotsa Mimba : Kuwombera kumachitika mkati mwa minofu ya ubongo.
- Kuwonongeka kwa madzi osakanikirana : Kutsekemera kumachitika pamtunda pakati pa awiri a memphane omwe amaphimba ubongo.
- Kuchepetsa Matenda: Kutaya thupi kumachitika mkati mwa mpweya wa ubongo, umene ulibe minofu ya ubongo, koma m'malo mwake umadzazidwa ndi madzi odziwika ngati cerebro-spinal fluid. Magazi mkati mwa ventricles sichimayambitsa matenda okhaokha, koma amachititsa kuti hydrocephalus akhale ndi vuto lomwe likhoza kupweteka kwambiri komanso ngakhale imfa.
- Kuchepetsa Mimba : Kutaya thupi kumachitika kunja kwa minofu ya ubongo pafupi ndi fuga.
Kukwapulidwa kwa magazi kumayambitsa kawirikawiri chiwiya cha magazi chomwe chimapangitsa kuti magazi asokonezeke.
Magazi mkati mwa ubongo amachititsa mutu wopweteka kwambiri, womwe umatchulidwa ndi anthu ngati mutu woipitsitsa wa miyoyo yawo.
Pamene magazi amasonkhana mu ubongo, ziwalo za ubongo zimagwiritsidwa ntchito motsutsana ndi makoma a chigaza. Izi zimawonjezera kupsinjika mkati mwa ubongo, mpaka magazi amatha kupita kumadera opanikizika kwambiri. Maderawa amasiya kugwira ntchito ndi kuyambitsa zizindikiro zomwe zimachokera ku chizungulire, kunyowa ndi kusanza kumutu kumaphatikizapo zizindikiro zomwe zimayambitsa zilonda . Zizindikiro zowonongeka kwapachimwi siziyenera kunyalanyazidwa monga momwe nthawi zambiri zimatha kukhalira mofulumira komanso poipiraipira, zimatha kupha mwadzidzidzi.
