Kuona kusinganzwisisiki ndiko kukanganisa kwekufamba, fomu, ukuru kana ruvara mundima inoonekwa. Mafungiro ekuona angave ari mugumisiro wekurohwa mumhepo yelopital, iyo iri kumashure kwe cerebral cortex uye ndiyo nzvimbo huru yekuona maonero.
Kushungurudza kunogona kukonzerwa kana nevhavha inodzivisa kuputika kweropa kuuropi (inonzi ischemic stroke) kana neropa rekuchenesa uye kudzivirira ropa richiyerera kuuropi (inonzi chirwere chepfungwa).
Kurwiswa kwemashure mashoma , kana "kurohwa kwechidiki," kunokonzerwa nechinguva chiduku.
Migumisiro yeStroke
Kana chirwere chikaitika uye kubuda kweropa hakugoni kusvika kunharaunda inodzora muviri unoshanda, chikamu ichocho chemuviri chinorega kushanda sezvinofanira. Kana chirwere ichocho chikaitika kumucheto kweuropi, somuenzaniso, zvinenge zvichida kuti imwe nhanho yemuono ichatadza.
Migumisiro yekurohwa inobva pane zviverengeka zvinokonzera, kusanganisira nzvimbo yekudzivirirwa uye kuti hutano hwehupi hunovhiringidzwa sei. Zvisinei, nokuti rumwe rutivi rweuropi runotarisa rumwe rutivi rwomuviri, kurohwa kunobata rumwe rutivi kuchaguma nehutano hwehutano kune rumwe rutivi rwemuviri unhu hunoita. Somuenzaniso, kana chirwere ichi chikaitika muuropi kurudyi, rutivi rworuboshwe rwemuviri (uye ruboshwe rwechiso) ruchabatwa, runogona kubudisa chero kana zvimwe zvinotevera:
- Kuparara kwerutivi rworuboshwe rwemuviri
- Zviratidzo zvinetso kusanganisira maonero ekuona
- Kurumidza, kufungisisa tsika yekuita
- Kurasika kurasika
Kana chirwere ichi chikaitika kurutivi rworuboshwe rweuropi, rutivi rworudyi rwemuviri ruchakanganiswa, kubudisa zvimwe kana zvose zvinotevera:
- Kufa kwepachiviri kurudyi rwomuviri
- Kutaura / matambudziko emitauro
- Chinononoka, kuchenjerera tsika yekuita
- Kurasika kurasika
Kana chirwere chinowanikwa muuropi chikaitika, zvichienderana nekuoma kwekukuvadzwa, chinogona kukanganisa mativi maviri omumuviri uye inogona kusiya mumwe munhu "muchero-mu".
Apo chinenge chakavharwa-muhurumende ichiitika, murwere anowanzokwanisa kutaura kana kupedza chero kufamba kuno pasi pemutsipa.
