Nei vana vakaberekwa vane Down syndrome?

Down's syndrome inowanzojairika yakawanda yezvirwere: maererano nehuwandu, inowanikwa mune imwe mwana achangoberekwa mazana manomwe. Kuziva kuti chirwere chacho chinogona kunge chichionekwa nekurapwa pamuviri panguva yekuzvitakura, asi pakupedzisira kuporesa mwana asati azvarwa kana mushure mokuberekwa, mushonga wemazuva ano haugone. Nokudaro, vabereki vazhinji munguva yemberi vanonyanya kunetseka pamusoro pemubvunzo wekuti nei vana vane Down syndrome vakaberekwa uye kuti vangadzivirira sei. Mushure mezvose, kukanganisa mukukura kwepfungwa uye kwemuviri kune vakadai vaduku kwakakosha uye haisi nguva dzose yakanyatsogadziriswa nekutora mishonga uye kudzidzisa kwakasimba.

Zvinokonzerwa nekugadzirwa kwechirwere

Mishonga yemazuva ano yakaratidza kuti zvikonzero zvinotsanangura kuti nei vana vane Down syndrome vakaberekwa havakwanisi kuenderana nemamiriro ekunze enyika, rudzi rwemamai nababa, mararamiro avo kana mararamiro ehupenyu, uye hukama hwemhuri umo mhuri inorarama.

Ichi chirwere chinokonzerwa nokuvapo mujenotype yemwana yeimwe chromosome. Mune masero ose emuviri womunhu ane ma chromosomes makumi mana nemakumi mana, anotarisirwa kuendeswa kwehutano kubva kuvabereki kuvana. Zvose zviri zviviri zvakaparadzana: varume nevakadzi. Asi dzimwe nguva chirwere chakakomba chemajini chinowanikwa, saka imwe kromosome inowanikwa 47 inowanikwa mumakamuri maviri ema chromosomes. Ndokusaka vana vakaberekerwa, kuzorapwa kwakakwana kwacho hakusviki, nokuti munguva yedu, kusvibiswa kwezvisikwa hazvibvumirwi kugadziriswa.

Ngatimboongororei zvakanyanyisa zvinhu zvinokosha zvikuru, simba razvo rinogona kutungamirira kune chitarisiko chemwana anorwara:

1. Zera raamai kune makore 33-35. Dzidzo dzakaratidza kuti njodzi yekuva nemwanakomana kana mwanasikana neArt syndrome inonyanya kukurumbira muvakadzi vakadaro. Izvi zvinokonzerwa nekutanga kwekukwegura kwomuviri kana zvichikwanisa kubereka mazai asina kuberekwa, kana kutapurirwa zvirwere zvemuviri wevakadzi. Kazhinji vanaamai vakadaro vasati vazvarwa vakaberekerwa vana vakafa kana vakafa vachiri vaduku. Saka, kana iwe uri pangozi, panguva yekuzvitakura, amniocentesis inokurudzirwa, umo amniotic fluid inotorwa uye zvino kuongorora kwakakodzera kunoitwa. Usakanganwa iyi nzira: paunodzidza mubvunzo wekuti nei mwana ane Down syndrome achigona kuberekwa, vanachiremba vakagadzira chokwadi chinonakidza. Kana vari vakadzi vaduku vari pasi pemakore makumi maviri nemashanu mukana wekuberekwa kwechecheche ane chirwere chakadai ndi101400, mune vakadzi vanozvara, vane makore anopfuura makore 35, njodzi yakawanda zvikuru: paavhareji, imwe nyaya yekuberekwa 350.
2. Hereditary factor. Kunyange zvazvo zvichizivikanwa kuti varume vane chirwere chakadaro havasi vana, 50% yevakadzi vane Down's syndrome vanogona kuva nevana. Zvisinei, pane dzimwe nguva, vana vanogara nhaka iyi chirwere, saka zvakakodzera kufungisisa kana zvakakosha kuti ienderere mberi nekurwara kwakadaro.
3. Zera rebaba. Chimwe chezvikonzero nei mwana-pasi achigona kuberekwa ndechokuti baba vane makore anodarika makumi mana nemakumi mana. Munguva iyi, hutano hwemhino hunoderera zvishoma, saka kubudiswa kweii ine chirwere chisina kunaka uye mungozi yekutukura chirwere ichi chakakomba chinowanzoitika.
4. Muchato pakati pehama dzepedyo. Hazvisi nyore kuti mune dzimwe nyika dzenyika zvinorambidzwa kuroorwa kwete vehama chete, asi kunyange vakoma vekutanga nevakoma vevanun'una nehanzvadzi.
5. Nyanzvi idzi dzakasimbisa kuti nei vana vane Down syndrome dzimwe nguva vachizvarwa: mukuru mukadzi wacho panguva yekuzvarwa kwomwanasikana, iyo yakanyanya kuva mukana wekuzvarwa kwemuzukuru anorwara kana muzukuru.
