Lezizifo Eziyinkimbinkimbi Ziphazamisa okwesikhashana Imemori
I-amnesia yomhlaba wonke ejwayelekile (TGA) yi-syndrome engaqondakali eyenza ukuhluleka okuncane ukudala izinkumbulo ezintsha. Ngokuvamile kwenzeka kubantu abaneminyaka ephakathi noma asebekhulile. Lesi sifo asivamile, senze cishe cishe ku-23.5 kuya ku-32 kubantu abayi-100 000 ngonyaka kulabo abangaphezu kweminyaka engama-50.
Abantu abane-TGA bavame ukuphinda babuye umbuzo ofanayo, njengoba kungenzeka bangakhumbuli ngaphezu kwemizuzu embalwa ngesikhathi.
Inkinga ngokuvamile ihlala emahoreni owodwa kuya kwangu-10. Ngaphezu kokuhluleka ukwakha izinkumbulo ezintsha (i-anterograde amnesia ), ngokuvamile kuvamile ukuphindaphindiwe kwe-amnesia, okusho ukungakwazi ukukhumbula izinto ezenzeke esikhathini esidlule, ukubuyela emuva noma kuphi kusuka emahoreni kuya, ngokungajwayelekile, iminyaka.
Abantu abane-TGA basakwazi ukuchaza ukuthi bangobani futhi bakhumbule ukuthi bangenza kanjani imisebenzi enzima njengokushayela noma ukupheka. Ngenkathi i-amnesia isici esivelele kunazo zonke, ezinye iziguli zikhononda ngekhanda, isicashu, isizungu noma ezinye izimpawu ngesikhathi se-TGA.
Ngezinye izikhathi i-amnesia yomhlaba wonke yesikhashana ingabangelwa yizehlakalo ezingokomzwelo. Izinguquko ze-Postural, ukuphakama okuphezulu, ukuvivinya umzimba noma ukuthwala phansi kungase futhi kunciphise isiqephu.
Ngesikhathi i-TGA iphindaphinda kuphela ngamaphesenti angu-15 yesikhathi futhi ayikhombisi inkinga enkulu kakhulu, imemori efana naleyo ingase ivele ekubanjeni noma ngokushaya , okwenza kube kubalulekile ukuhlolwa ngokushesha.
Isizathu se-TGA
Isizathu se-TGA asikaziwa, kodwa izimpawu zibonisa ukungasebenzi emsebenzini we-lobe wesimanje, indawo yobuchopho equkethe i-hippocampus futhi ibalulekile ekubunjweni kwezinkumbulo ezintsha. Ezinye izifundo zibonise izilonda kule ndawo kulabo ababhekene ne-TGA, kodwa lezi zilonda azibonakali njengezivame ukuhambisana nesifo sohlangothi, njengoba zivame ukunyamalala.
Imikhombandlela ihlanganisa ushintsho oludlulayo lokugeleza kwegazi kulezi zifunda, noma mhlawumbe into eguquguqukayo ehilela izinguquko ezincane emisebenzini kagesi. Kungenzeka ukuthi i-syndrome ibangelwa izizathu ezingaphezu kweyodwa.
Ngenkathi ukunciphisa okwesikhashana ukugeleza kwegazi (ukuhlasela kwe-ischemic okudlulayo noma "i-TIA") ku-hippocampus kungalingisa i-TGA, i-TGA ivame ukuhlala isikhathi eside kunokuhlaselwa kwe-ischemic evamile. Ayikho ubudlelwano obucacile phakathi kwezimo zokubeka isifo socansi kanye ne-TGA.
Ezinye izifundo zibonisa ukuthi i- migraine ihlotshaniswa ne-TGA. Nakuba kuyaziwa kakhulu ngokubangela ikhanda, izimo ze-migraine zingabangela ngempela ukwehluleka okukhulu kwezinkinga zezinzwa ngenxa yokuhamba kancane komsebenzi kagesi ngaphesheya kobuchopho. I-Migraine ingabangela ushintsho lwe-MRI luboniswe kuma-TGA amacala, futhi isikhathi sesikhathi sokuhlasela kwe-migraine ne-TGA kufana. Kodwa-ke, i-Migraines ithinta abantu abaneminyaka eminingi, ikakhulukazi abasebasha, kanti imiphumela ye-TGA iphakathi kwabantu abadala asebekhulile.
Ekuqaleni, odokotela abathile bakholelwa ukuthi i-TGA ingase ibe yinkinga yezifo ezingenasifo esicacile, kodwa ukungabi khona kwamanye izimpawu zengqondo ezigulini kanye nesethulo esifanayo kubantu abaningi kangaka abenza lokhu kungabonakali.
Ukuphathwa kwe-TGA
I-TGA ngokwayo ayidingi ukwelashwa, njengoba isiqephu sizovame ukudlula emahoreni angu-24.
Kuyinto evamile ukuvakashela umuntu nge-TGA, kodwa, ukuqinisekisa ukuthi inkinga enkulu kakhulu ayibangeli izimpawu. Isibonelo, ngenkathi kungekho ukwelashwa okuqondile, iziguli kufanele zithole i-thiamine ukuze zingabandakanyi ukukhathazeka kwe-Wernicke, uhlobo lokulahlekelwa kwememori ngenxa yamazinga anganele amavithamini thiamine.
Ukuxilongwa kokuhlukana kufaka phakathi ukuhlukunyezwa okuvela kwi-losi ye-mesial temporal. Ngenxa yalesi sizathu, ukuthola i- electroencephalogram (i-EEG) umqondo omuhle, nakuba i-EEG evamile ingabandakanyi amathuba okusebenza okucashile okujulile kakhulu okumele atholakale yi-electrodes ye-scalp.
Uma kukhona ukukhathazeka okuphezulu kokuthunjwa, i-EEG ende ingahle iphakanyiswe, mhlawumbe umuntu owathatha isikhathi sokulala.
Ukuhlaselwa kwe-ischemic okudlulayo noma ukushaya isisu kungalingisa i-TGA, nakuba lokhu kungavamile ngaphandle kweminye izimpawu ezifana nobubuthakathaka noma ukunganaki. I-MRI ingasetshenziselwa ukukhipha lokhu kungenzeka, ikakhulukazi uma othile enesisindo esibucayi sezinto ezinjenge- sikashukela , i- cholesterol ephezulu , ukucindezela kwegazi noma ukubhema.
U-amnesia we-Psychogenic uhlobo lokuguqulwa kwesifo, okusho ukuthi isikhalazo sengqondo sibonisa ukuthi kunesidingo esingokwenyama. Ngokungafani ne-TGA, iziguli ezine-psychological amnesia zikhohlwa igama lawo noma ezinye izingcezu zolwazi lomuntu siqu. Ezinye izinto ezibalulekile okufanele zicatshangwe nge-TGA zihlanganisa ushukela wegazi ophansi , ukuphuza utshwala noma izidakamizwa noma ukuhoxiswa, i- encephalitis , noma i- delirium , nakuba lezi zimo ngokuvamile zikhona ngokudideka okuncane kunokuba nje kulahlekelwe imemori.
Isibikezelo
Abantu abane-TGA abonakala bengengozini yokwanda kwesifo noma isifo esiyingozi kakhulu. Ucwaningo olunye luphakamisa ukuthi ukulahlekelwa kwememori okucashile kungase kuhlale ngemuva kwesiqephu, nakuba abanye bengatholanga inhlangano enjalo.
Kuyinto evamile ukukhathazeka ngokuthi kungenzeka ukuphindaphinda izimpawu. Ukuphindaphindiwe okunjalo akuvamile, kepha akunakwenzeka, futhi kumele kuqhutshekwe ukuhlolwa kwezinye izincazelo.
