"Oh, kati nkaddiye... Sirina kye nzijukira." Wali olowoozezzaako ekintu kye kimu? Oluusi tuwulira nga tutya katono bwe twerabira amangu ekisumuluzo we kyali oba kye twagala okubuulira omuntu. Ffenna tweraliikirira katono ku kujjukira kwaffe naddala nga tukaddiwa. Wabula leero tugenda kwogera ku mawulire agagenda okukkakkanya okweraliikirira kuno katono n’okutuleetera essanyu eritono ku mitima gyaffe.
Kino ekipya kye bazudde kye ki?
Okunoonyereza okukulu ennyo okwakolebwa gye buvuddeko mu Amerika kuzudde ekintu ekyewuunyisa ennyo. Kwe kugamba, ekiseera bwe kigenda kiyitawo, okuva ku mulembe okudda ku mulala , obunene bw’obwongo bw’omuntu bweyongera mpolampola.
Kino kyazuulibwa mu kunoonyereza okumanyiddwa ennyo okumaze emyaka nga kugenda mu maaso. Kiyitibwa okunoonyereza ku mutima mu Framingham . Mu kunoonyereza kuno, baageraageranya ebikwata ku bifaananyi by’obwongo okuva mu bantu abazaalibwa mu myaka gya 1930 ne sikaani z’obwongo okuva mu bantu abazaalibwa mu myaka gya 1970. Kilowoozeeko ng’okupima obunene bw’obwongo bw’omulembe gwa bajjajjaffe, omulembe gwa bazadde baffe oba omulembe gwaffe.
Ebyavaamu byeyoleka bulungi. Ebipimo ebikulu ebiwerako, gamba ng’obunene bw’obwongo n’obuwanvu bw’ekitundu ky’omubiri ekiyitibwa cortical surface area, binene nnyo mu bantu abazaalibwa mu myaka gya 1970 okusinga abo abazaalibwa mu myaka gya 1930. Mu ngeri ennyangu, obwongo bw’emilembe emipya mu mubiri bunene katono.
Kiki ekituuka ku bulwadde bw’okusannyalala ng’obwongo bweyongera obunene?
Okay, kati oyinza okuba ng'olowooza nti, "Obwongo obunene katono bugasa ki?" Kino mu butuufu kikulu nnyo okusinga bw’oyinza okulowooza. Naddala nga tulina obulwadde bw’okubulwa amagezi , embeera eyinza okukula nga tukaddiwa.
Okusookera ddala, obulwadde bw’okubulwa amagezi kye ki?
Obulwadde bw’okubulwa amagezi, mu ngeri ennyangu, mbeera obutoffaali bw’obwongo mwe bwonooneka ng’abantu bakaddiwa, ne bukendeera mpolampola emirimu gyabwe. Kino kiyinza okuviirako omuntu okubulwa okujjukira, obutasobola kulowooza bulungi, okukaluubirirwa okusalawo, n’obutasobola kukola mirimu gya buli lunaku ku lwabwe. Obulwadde bwa Alzheimer ’s kye kika ky’obulwadde bw’okusannyalala obusinga okubeerawo.
Endowooza y’obwongo ‘reserve’.
Wano we wava enkizo y’obwongo obunene Bannasayansi kino bakiyita ‘brain reserve’ . Kino ka tukitegeere n’ekyokulabirako eky’enjawulo.
Teebereza obwongo bwo nga ttanka ennene ey’amazzi. Obulwadde ng’obulwadde bw’okubulwa amagezi buba ng’akatuli akatono mu ttanka eno, era amazzi gakulukuta. Kati, ttanka yo bw’eba nnene nnyo, ne bwe kiba nti obutuli obutono obutono bukulukuta amazzi amatono, mu ttanka mujja kuba wakyaliwo amazzi mangi, nedda? Ekyo kitegeeza nti omulimu gwa ttanka tegujja kulemesebwa nnyo.
Mu ngeri y’emu, obwongo bwe bweyongera okukula, obutoffaali bwabwo n’enkolagana yaabwo byeyongera. Olwo, ne bwe kiba nti obutoffaali bw’obwongo obumu busaanawo nga tukaddiwa oba olw’endwadde, ‘ekifo’ oba ‘ekitereke’ kitondebwawo ekiyinza okunyiga ebyonoonese n’okukuuma enkola y’obwongo eya bulijjo .
Abanoonyereza balowooza nti okugaziwa kuno okw'obwongo kuyinza okwongera okuziyiza endwadde ezijja n'okukaddiwa n'okukendeeza ku bulabe bw'okubulwa amagezi okutwalira awamu .
| Omulembe | Engeri z’obwongo | Ebiyinza okukosebwa |
|---|---|---|
| Abantu abazaalibwa mu myaka gya 1930 | Voliyumu y’obwongo ntono nnyo | Okubeera nga batera okukwatibwa ebiva mu bulwadde bw’okusannyalala. |
| Abantu abazaalibwa mu myaka gya 1970 | Okwongera ku bunene bw’obwongo n’obuwanvu bw’obwongo. | Obusobozi obusingawo okugumira ebiva mu bulwadde bw’okusannyalala (okweyongera mu ‘brain reserve’). |
Lwaki obwongo bwaffe bweyongera obunene?
Wadde nga tekisoboka kulaga nsonga emu yokka lwaki kino kivuddeko, waliwo ebintu ebikulu ebiwerako bannassaayansi bye bakkiriza.
1. Emize gy’ebyobulamu n’obulamu obulungi: Kati tufaayo nnyo ku bulamu okusinga bwe kyali kibadde. Endya ennungi okuva mu buto, okumanya obukulu bw’okukola dduyiro, puleesaOkufuga endwadde nga sukaali ne kolesterol kikosa butereevu enkula y’obwongo ennungi.
2. Okulongoosa mu by’enjigiriza: Omutindo gw’ebyenjigiriza gweyongedde okuva ku mulembe okudda ku mulala. Okusoma ye dduyiro asinga ku bwongo. Bwe tuyiga ebintu ebipya ne tugonjoola ebizibu, enkolagana empya ey’obusimu ekolebwa wakati w’obutoffaali bw’obwongo. Kino nakyo kiyamba mu nkula y’obwongo.
3. Ensonga z’obutonde: Era kirowoozebwa nti ensonga z’obutonde, gamba ng’okukendeeza ku kukwatibwa eddagala erimu ery’obulabe (e.g. lead), nazo ziyinza okubaako kye zikola.
Okunoonyereza kuno kutuufu 100%? Biki ebikoma?
Nga bwe kiri mu kunoonyereza kwonna okwa ssaayansi, waliwo obuzibu obumu bwe tulina okutegeera.
Ekikulu, okunoonyereza kuno kwakolebwa ku bantu abasinga obungi abazungu, abasomye obulungi, era abalamu obulungi ababeera mu Amerika. N’olwekyo, kyetaagisa okwongera okunoonyereza okuzuula oba ebivuddemu bino bitukwatako mu Sri Lanka, oba ku balala abali mu buwangwa n’obulamu obw’enjawulo okwetoloola ensi yonna.
Ate era wadde nga kino kirungi nnyo era kinyuma nnyo ekizuuliddwa, abakugu balaga nti kijja kutwala obudde bungi okutegeera enkola entuufu eri emabega wa kino.
Naye, okunoonyereza kuno kutuwa obubaka obw’omuwendo ennyo: nti okusalawo kwe tukola ku bulamu bwaffe, obuyigirize bwe tufuna, n’obulamu bwaffe bikwata butereevu ku bulamu bw’obwongo bwaffe n’ebiseera eby’omu maaso.
Obubaka Obutwala Awaka
- Okunoonyereza okupya kulaga nti obunene bw’obwongo bw’omuntu bweyongera okuva ku mulembe okudda ku mulala.
- Olw’okuba okugaziwa kw’obwongo kwongera ku ‘brain reserve’, kiyinza okwongera okuziyiza ebiva mu ndwadde ezeekuusa ku myaka ng’okubulwa amagezi.
- Bannasayansi balowooza nti endya ennungi, okusoma, n’obulamu obulungi biyinza okuba nga bye bivuddeko kino.
- Wadde nga gano mawulire malungi, kyetaagisa okwongera okunoonyereza okukakasa kino. N’olwekyo, bulijjo tusaanidde okufaayo ku bulamu bw’obwongo.
- Singa ggwe oba omuntu mu maka go afuna obuzibu mu kujjukira, okwerabira oba enkyukakyuka endala, kikulu nnyo okwogera n’omusawo wo nga totya oba okuswala olw’ensonga eyo.
