Kazhinji, zvirwere zvakaita seCJD zvinokura pasina chikonzero chakajeka, asi zvimwe zvinhu zvinoisa njodzi zvakaonekwa.
- Nhoroondo Yemhuri : Vanhu vanosvika 15% vanorwara nezvirwere izvi nekuda kwekusakwana kwemajini (kusakwana kwemajini kunonzi `PRNP`) kunopfuudzwa nezvizvarwa.
- Utachiona : Izvi hazviwanzoitiki. Dzimwe nguva, chirwere ichi chinogona kutapuriranwa kana munhu achitora nyama kubva kumunhu ane chirwere ichi, kana kana michina inoshandiswa panguva yekuvhiyiwa isina kucheneswa nemazvo.
- Kudya nyama ine utachiona: Kudya nyama yemombe ine chirwere che " mad cow disease " (Bovine Spongiform Encephalopathy ) kunogona kukonzera chirwere chinonzi vCJD. Chirwere ichi pachakapararira muEurope muma1990, vanhu vashoma vakafa nechirwere ichi.

Chirwere cheprion chinoonekwa sei?
Zvinogona kuoma kuona chirwere ichi nekuti zviratidzo zvinogona kufanana nezvimwe zvirwere. Kana uine zviratidzo zvakaita sekukanganwa, chiremba wako anotanga abvisa zvimwe zvinokonzera, zvakaita sestroke kana bundu remuuropi. Miedzo inotevera inogona kuitwa:
- Kuboorwa Kwemusana/Kuboorwa Kwemusana: Izvi zvinosanganisira kuisa tsono diki pakati pemapfupa maviri emusana uye kutora sampuli diki yemvura yakakomberedza uropi hwako nemusana (cerebrospinal fluid). Huwandu hwemamwe mapuroteni ari mairi hunogona kuyedzwa kuti uwane pfungwa yechirwere chacho.
- MRI scan (Magnetic Resonance Imaging): Izvi zvinoshandisa magineti ane simba nemasaisai eredhiyo kutora mifananidzo yakadzama yeuropi. Dzimwe nguva zvinogona kuratidza shanduko dzakati wandei muuropi dzinoonekwa muzvirwere zveprion.
- Kuongororwa kweCT (Computerized Tomography): Kuongororwa kwemaX-ray kunotorwa pamwe chete kuti pave nemufananidzo wakajeka wehuropi.
Chinhu chinonyanya kukosha: Nzira chete yekuva nechokwadi chekuti munhu ane chirwere cheprion ndeyekutora chidimbu chidiki chenyama kubva muuropi (brain biopsy). Asi uku kuvhiyiwa kune njodzi huru. Saka izvi zvinoitwa chete kana paine fungidziro yekuti chingave chimwe chirwere chinorapika.
Kurapa nekudzivirira chirwere ichi
Panguva ino, hapana mushonga wezvirwere zveprion. Mishonga iripo inongodzora zviratidzo chete uye inopa zororo kumurwere. Izvi zvinosanganisira mishonga inoderedza marwadzo, mishonga inorwisa kuora mwoyo, uye mishonga yekuderedza kuzvidya mwoyo. Sezvo mamiriro emunhu ane chirwere cheprion achiipa zuva nezuva, anenge achida rubatsiro pamabasa ezuva nezuva. Vangangoda kuiswa catheter kuti vabudise weti, vasave nemvura yakawanda mumuviri, uye vadye nechubhu kana vasingakwanise kudya.
Chirwere ichi chinogona kudzivirirwa here?
Hapana nzira yekudzivirira zvirwere zverudzi rweprion, asi matanho aya anogona kubatsira kuderedza njodzi yekupararira kwechirwere kuburikidza nehutachiona kana chikafu:
- Kuchenesa nekuuraya utachiona pamidziyo yekurapa nemazvo.
- Kana uine chirwere cheprion kana kuti une nhoroondo yemhuri yacho, usapa nyama kana nhengo dzemuviri.
- Kudya nyama chete ine chitupa chekuti yakachengeteka.
Kupararira kwe "chirwere chemombe chinopenga" kwave kudzorwa zvakanaka nekuda kwemitemo yakasimba yakaiswa nenyika dzakawanda pasi rose maererano nechikafu nenyama yemombe inopiwa mombe.
Mharidzo Yekuenda Nayo Kumba
- Zvirwere zvePrion iboka rezvirwere zvisingawanzoitiki asi zvakakomba zvinokuvadza uropi.
- Muzvirwere izvi, ndangariro, maitiro, uye kufamba kwemuviri zvinoderera nekukurumidza . Kukurumidza uku ndiko hunhu hukuru hunosiyanisa chirwere ichi nezvirwere zvakaita seAlzheimer's.
- Zvakaoma kuziva chirwere chacho nemazvo, uye bvunzo dzakati wandei dzinodiwa kuti zviitike.
- Kunyangwe pari zvino pasina mushonga chaiwo weizvi, zviratidzo zvinogona kudzorwa uye murwere anogona kupihwa rubatsiro.
- Kana iwe kana mumwe munhu waunoziva akaona shanduko isingatarisirwi mundangariro dzake, hunhu hwake, kana mafambiro ake, zvakakosha kuona chiremba nekukasika kuti akupe mazano .
