Zvirwere zveNeurodegenerative zvinoumba dambudziko rakakura rehutano hwevanhu nekuda kwekukanganisa kwekuziva uko kunovaratidza. Pakati peyakawanda bvunzo dziripo dzinoshandiswa kuratidza kudzikira kwekuziva, tinowana iyo MoCA kana "Montreal Cognitive Assessment".

Chirwere cheAlzheimer (AD) ndicho chinowanzoitika chirwere cheurourodegenerative muvanhu vane makore anodarika makumi matanhatu nemashanu. Iyo inoratidzirwa nekufambira mberi kwekushomeka kwemabasa ekuziva, kunyanya ndangariro, ine simba rakakura pamabasa ehupenyu hwezuva nezuva. 

MuFrance, vangangoita vanhu mazana masere vanofungidzirwa kuti vanobatwa neAD kana chirwere chakabatana. Izvi zvinomiririra munhu anofungidzirwa, mutengo wezvemagariro uye zvemari. Kuchengetwa kwavo kunova kupfuura nakare kose nyaya yehutano hweveruzhinji. Nekudaro, muFrance, 800% yematambudziko ehumwe dementia haisiyo nyaya yematanho ekuongorora pamwe nekusimbiswa nenyanzvi. Basa rakawanda rakanangana mumakore achangodarika kune varwere vane hurema hwekuziva kusanzwisisika kana "Hunyoro hwekuziva Kukanganisika" (MCI). Iyo yekupedzisira inozivikanwa nekuvapo kwekukanganisa kushoma kwekuziva, kunyanya munzvimbo yekurangarira, mune varwere vanoramba vakazvimirira muhupenyu hwezuva nezuva (Petersen et al., 000).

Kuongororwa kweMCI kunoda kushandiswa kweimwe kana kupfuura nekukurumidza, bvunzo dzakareruka idzo dzinodiwa metrological (kuyera) hunhu hwakagadziriswa. Yakagadziriswa muna 2005 naDr.Ziad Nasreddine, wekuCanada chiremba wezveuropi, iyo MoCA bvunzo inoitirwa vanhu vakuru uye vanhu vakura vane fungidziro yehunyoro hwekuziva kwekukanganisa, hunyoro dementia kana chirwere cheeurodegenerative. Mune makumi masere muzana ezviitiko, inoshandiswa kuongorora chirwere cheAlzheimer, kunyanya kana munhu achiwanzoisuwa, dzimwe nguva inovhiringidzika. Yakave yakashandiswa kwemakore makumi maviri munyika mazana maviri uye inowanikwa mumitauro makumi maviri. Izvo hazviite kuti zvikwanisike kumisikidza kuongororwa asi inonyanya kushandiswa kunanga kune mamwe bvunzo. Yakagashirawo kutarisisa kwekukwanisa kwayo kuona kukanganisika kwekuziva mukati mevanhu vane chirwere chePasinson.

Inopedza maminetsi gumi kusvika gumi nemashanu, bvunzo yacho inosanganisira kuongorora zvinyoro nyoro kusvika pakati nepakati, nekuongorora mabasa anotevera: 

• pfungwa;
• kuisa pfungwa;
• Executive mabasa;
• Ndangariro;
• mutauro;
• visuo hunyanzvi hwekuvaka;
• kubvisa masimba;
• kukarukureta;
• kutungamira.  

Muongorori anopa quiz inoda mhinduro pfupi, gumi mabasa sekudhirowa cube, wachi uye chiyeuchidzo chendangariro chine mazwi akasiyana ekurangarira. 

Iwo iwo mirairo yakanangana zvakakwana kutungamira zvakajeka muongorori mukati memubairo. Saka anofanirwa kuve neiyo grid yekukora uye nemirairo yekupedzisa MoCA iri muruoko. Nemagwaro maviri aya nepenzura, anoenderera mberi nekuyedza nekutevera mirairo uye panguva imwe chete achiyera mhinduro dzemunhu. Sezvo mamaki eMoCA anoenderana nedanho redzidzo, vanyori vanokurudzira kuwedzera poindi kana dzidzo yemurwere iri makore gumi nemaviri kana zvishoma. Nepo mibvunzo ichiita senge iri nyore, haisi nyore kune vanhu vane dementia.

Iwo maekisesaizi akavakirwa pa:

• ndangariro-pfupi-pfupi (mashanu poindi);
• anoonekwa uye enzvimbo kugona ne wachi bvunzo (3 poindi);
• basa rinoitwa kuteedzera cube (1 poindi);
• Executive mabasa;
• phonemic fluence (1 poindi);
• kubvisa mazwi (2 poindi);
• kutarisisa, kuisa pfungwa uye kushanda ndangariro (1 poindi);
• akateedzana kubvisa (3 poindi);
• kuverenga nhamba kurudyi kumusoro (1 poindi) uye kumashure (1 poindi);
• mutauro nekuratidzwa kwemhuka dzinovaraidza (3 mapoinzi) uye kudzokororwa kwemitsara yakaoma (2 mapoinzi);
• kutariswa munguva nenzvimbo (nhanhatu).

Chiyero chekuongorora chinoitwa zvakananga pagridhi uye panguva imwe chete nemuedzo. Muongorori anofanirwa kunyora mhinduro dzemunhu uye kumaka (zvakanaka kune imwe poindi uye zvisirizvo zvemapoinzi 0). Chikamu chakakwira kubva pamapoinzi makumi matatu chinobva chawanikwa. Iwo zvibodzwa zvinogona kududzirwa seinotevera:

• = 26/30 = hapana kuora mwoyo kwekuziva;
• 18-25 / 30 = kukanganisika kudiki;
• 10-17 = kukanganisika zvine mwero;
• Pasi pegumi = kukanganiswa kwakanyanya.
