Yu dɔktɔ go dɔn tɛl yu fɔ du Evoked Potential Test. Dat nem kin tan lɛk se i kɔmplikt smɔl, ɛn sɔntɛm i kin ivin mek pɔsin fred smɔl, nɔto so? Bɔt i rili nɔto natin fɔ fred. Na simpul tɛst we nɔ de mek pɔsin fil pen we dɛn kin yuz bɔku tɛm fɔ no impɔtant tin dɛn bɔt aw wi nervɔs sistɛm de wok. So lɛ wi tɔk bɔt ɔl dis insay simpul wɔd dɛn tide.
Fɔ tɔk am simpul wan, wetin na dis Evoked Potential Test?
Tink bɔt wi nervɔs sistɛm lɛk wan sistɛm we gɛt aywe dɛn we de rɔn ɔlsay na wi bɔdi. Infɔmeshɔn (ilɛktrik signal) kin travul go ɛn kam bak na dɛn rod ya. Fɔ ɛgzampul, we yu si sɔntin, da infɔmeshɔn de kin kɔmɔt na yu yay ɛn go na yu bren tru dɛn nerve path dɛn ya. Na di sem tin kin apin we yu yɛri sɔntin.
di Evoked Potential Test de mכsu aw fast εn aw ilektrikal signal dεm de travul along dεn nεv path dεm ya. I de mɛzhɔ aw yu bren ɛn nerv dɛn de ansa to tin dɛn we de mek yu fil fayn - lɛk fɔ sho yu pikchɔ, yɛri sawnd, ɔ fɔ gi yu wan rili smɔl ilɛktrik shɔk.
Dis min se yu fɔ put smɔl smɔl mɛtal plet dɛn (ilɛktrod) na yu ed ɛn sɔntɛnde ɔda pat dɛn na yu bɔdi. dis dεm de ‘kapch’ di ilektrikal signal dεm we de jεnarεt na yu nεv dεm εn bren fכ ansa di stimulashכn.
Wetin dis tɛst de luk fɔ?
Sɔntɛnde, sɔm kayn pwɛl hat kin de pan di rod dɛm fɔ di nervɔs sistɛm. Dɛn tin ya kin tu smɔl fɔ mek dɛn no am bay we dɛn du nɔmal nyurolɔjik ɛgzamin. Yu nɔ go gɛt ɛni sayn fɔ di damej yet.
Di Evoked Potential Test kin no ivin rili subtil damej lɛk dis ali .
Dɔktɔ dɛn kin yuz dis tɛst wit ɔda tɛst dɛn fɔ no difrɛn tin dɛn we gɛt fɔ du wit di nervɔs sistɛm. Dis impɔtant mɔ fɔ no bɔt sik dɛn lɛk Multiple Sclerosis (MS) .
Apat frɔm dat:
- Fɔ no di tumbu ɔ ɔda tin dɛn we dɔn pwɛl di optik nɛv.
- Tεst di yεri abiliti (fכ yεri כ nכ yεri) fכ yכng bεlε pikin dεm.
- If yu sɔspɛkt kɔndishɔn lɛk bren stem tɔmɔs, mek dɛn kɔnfyus am.
- Monitor di nervous system function we yu de du sɔm ɔpreshɔn.
Aw dis difrɛn frɔm EEG?
Yu go mɔs dɔn yɛri bɔt EEG tɛst. Pan ɔl we dɛn ɔl tu de mɛzhɔ di ilɛktrik wok we di bren de du, difrɛns de bitwin dɛn tu.
- EEG (Ilektroɛnsɛfalogram): .Dɛn kin du dis bay we dɛn de rikodɔ di ilɛktrik wev dɛn we yu bren de pul we i jɔs sidɔm de, ɛn dɛn nɔ de mek ɛnitin we de mek i want fɔ du sɔntin. I tan lɛk se yu de lisin to yu bren in ‘brɔdkas’.
- Evoked Potential Test: Dis de sho aw di bren de ansa kwik ɛn aw fayn to sɔntin we de mek wi want fɔ du sɔntin (lɛk pikchɔ ɔ sawnd) we wi kin gi am bay wilful . I tan lɛk se yu aks kwɛstyɔn ɛn tɛst di ansa.
Wetin na di men kayn Evoked Potential Tests?
Tri men kayn we dɛn de fɔ dis tɛst. Yu kin du wan ɔr mɔ pan dɛn tin ya, i kin dipen pan yu sik ɛn wetin yu dɔktɔ de luk fɔ.

Yu dɔktɔ go tɛl yu mɔ bɔt dis. Nɔ fred fɔ aks if yu gɛt ɛni kwɛstyɔn.
Aw lɔng di tɛst kin tek?
Di tɛm kin difrɛn difrɛn wan bay di kayn tɛst we dɛn de du. Bɔku tɛm, i kin tek bitwin 60 ɛn 90 minit (wan awa ɛn af) . Yu kin de fil fayn insay dis tɛm. Sɔntɛnde, yu kin ivin slip. apat frכm di sכm ilektrikal stimulashכn we dεn gi we dεn de du di SEP tεst, nכ pen de frכm dεn tεst dεm ya.
Wetin di rizɔlt dɛn se?
di data (ilεktromagnetik wev dεm) frכm di tεst na wan spεshal tren nyurolכg כ nyurofysiolojist de analכz am εn dεn pripia wan ripot. We di dɔktɔ we de trit yu dɔn gɛt di ripɔt, i go ɛksplen to yu di tin dɛn we dɔn apin.
Bɔku tɛm, dɛn nɔ kin tink bɔt di tin dɛn we kin kɔmɔt frɔm dis tɛst fɔ dɛnsɛf. Dɛn kin jɔyn dɛn wit di sayn dɛm we yu gɛt, di tin dɛm we yu dɔn fɛn we yu de chɛk yu bɔdi, ɛn di rizɔlt dɛm fɔ ɔda tɛst dɛm lɛk MRI skan fɔ mek yu no di las tɛm fɔ no if yu gɛt di sik.
