Peb caug feeb tiv thaiv koj lub hlwb mus ib txhis

Txoj kev tshawb no tau ua los ntawm cov kws tshawb fawb ntawm American University of Maryland, thiab lawv cov txiaj ntsig tau luam tawm nyob rau hauv qhov teeb meem tshiab kawg ntawm Kev Tshawb Fawb Txog Kev Tshawb Fawb ntawm International Neuropsychological Society.

Kom txog rau ntawm txoj kev tshawb pom, cov kws tshawb fawb tau ntsuas lub hlwb kev ua haujlwm nrog fMRI ntawm cov neeg koom nrog noj qab haus huv hnub nyoog 55 txog 85 xyoos.

Pab neeg no tseem hais kom cov neeg koom ua cov haujlwm nco uas suav nrog txheeb xyuas cov npe nrov thiab tsis muaj npe.

Raws li txoj kev tshawb no, cov txheej txheem ntawm kev nco qab cov npe nto moo ua rau muaj kev sib txuas ntawm neural ntsig txog semantic nco, uas paub tias deteriorate sij hawm vim nco poob rau cov neeg laus.

Cov kev sim no tau ua 30 feeb tom qab kev tawm dag zog hnyav ntawm lub tsheb kauj vab, thiab tom qab ntawd lawv tau ua tib yam kev sim tab sis nyob rau hnub so thaum cov neeg koom tsis tawm dag zog.

Cov kws tshawb fawb pom tias kev tawm dag zog ua rau lub hlwb hauv 4 thaj chaw cortical lub luag haujlwm rau kev nco, qhov tseem ceeb tshaj plaws yog "hippocampus" - uas ua haujlwm sib xyaw thiab khaws cov ntaub ntawv thaum xav tau - piv rau so.

Cov kws tshawb fawb tau taw qhia tias lub hippocampus shrinks nrog lub hnub nyoog thiab cheeb tsam lub paj hlwb raug cuam tshuam rau cov proteins uas ua rau Alzheimer's kab mob.

"Cov kev tshawb fawb yav dhau los tau pom tias kev tawm dag zog ib txwm muaj tuaj yeem ua kom lub ntim ntawm hippocampus, tab sis peb txoj kev tshawb fawb muab cov ntaub ntawv tshiab tias kev tawm dag zog hnyav muaj peev xwm cuam tshuam rau thaj chaw tseem ceeb ntawm lub hlwb," said Carson Smith tus thawj coj tshawb fawb.

"Ib yam li cov nqaij ntshiv hloov mus rau kev tawm dag zog rov ua dua, ib qho kev tawm dag zog ib zaug tuaj yeem txhim kho kev sib txuas lus neurocognitive hauv txoj hauv kev uas txhim kho lawv cov kev hloov mus rau kev laus, ua kom muaj kev ncaj ncees thiab kev ua haujlwm, thiab tso cai rau kev nkag tau zoo dua rau kev nco."

Alzheimer's tus kab mob yog hom dementia ntau tshaj plaws, thiab nws ua rau muaj kev pheej hmoo ntawm kev xav thiab lub hlwb ua haujlwm, thiab nco tsis tau. Tus kab mob no maj mam poob mus rau qhov tsis muaj peev xwm ua haujlwm txhua hnub, thiab sib txuas lus nrog ib puag ncig, thiab qhov xwm txheej yuav ua rau tsis zoo rau qhov tsis ua haujlwm.
