Ebia wo duruyɛfo akamfo akyerɛ wo sɛ wɔnyɛ Evoked Potential Test. Ebia saa din no bɛyɛ te sɛ nea ɛyɛ den kakra, na ebia ɛyɛ hu kakra mpo, ɛnte saa? Nanso nokwarem no, ɛnyɛ biribiara a ɛsɛ sɛ wosuro. Ɛyɛ sɔhwɛ a ɛnyɛ den a ɛyaw nnim a wɔtaa de hwehwɛ nsɛm a ɛho hia a ɛfa sɛnea yɛn ntini ahorow no yɛ adwuma ho. Enti momma yɛnka ne nyinaa ho asɛm wɔ nsɛm a ɛnyɛ den mu nnɛ.
Sɛ yɛbɛka no tiawa a, dɛn ne saa Evoked Potential Test yi?
Susuw yɛn ntini ahorow no ho sɛ akwan akɛse nhyehyɛe a ɛnam yɛn nipadua nyinaa so. Nsɛm (anyinam ahoɔden nsɛnkyerɛnne) tu kwan kɔ saa akwan yi so kɔ anim ne akyi. Sɛ nhwɛso no, sɛ wuhu biribi a, saa nsɛm no fi w’ani so kɔ w’amemene mu fa saa ntini akwan yi so. Saa ara na sɛ wote biribi a.
Evoked Potential Test no susuw sɛnea anyinam ahoɔden nsɛnkyerɛnne fa ntini akwan yi so ntɛmntɛm ne sɛnea ɛkɔ yiye . Ɛsusu sɛnea w’amemene ne wo ntini yɛ wɔn ade wɔ nkannyan ho - te sɛ mfonini a ɛkyerɛ wo, nnyigyei bi a wɔte, anaasɛ anyinam ahoɔden a ɛbɔ wo ketewaa bi.
Nea ɛka eyi ho ne sɛ wode dade mprɛte nketewa (electrodes) bɛhyɛ wo ti nhwi ne ɛtɔ mmere bi a wo nipadua no afã afoforo so. Eyinom ‘kyere’ anyinam ahoɔden nsɛnkyerɛnne a ɛba wo ntini ne w’amemene mu de bua nkanyan no.
Dɛn na sɔhwɛ yi rehwehwɛ?
Ɛtɔ mmere bi a, ntini ahorow no akwan no betumi asɛe kakra. Eyinom betumi ayɛ anifere dodo sɛ wobetumi de ntini mu nhwehwɛmu a ɛfata ahu. Ebia wunnya nnyaa nneɛma a asɛe no ho sɛnkyerɛnne biara.
Evoked Potential Test no tumi hu ɔsɛe a ɛyɛ anifere koraa mpo te sɛ eyi ntɛm ara .
Nnuruyɛfo de sɔhwɛ yi ka nhwehwɛmu afoforo ho de hu tebea horow a ɛfa ntini ahorow ho. Eyi ho hia titiriw wɔ nyarewa te sɛ Multiple Sclerosis (MS) a wobehu mu .
Bio nso:

- Sɛ wususuw sɛ tebea horow te sɛ amemene mu akisikuru wɔ hɔ a, ma wonsi so dua.
- Hwɛ sɛnea ntini ahorow no yɛ adwuma bere a wɔreyɛ oprehyɛn ahorow bi no.
Ɔkwan bɛn so na eyi yɛ soronko wɔ EEG ho?
Ebia woate EEG nhwehwɛmu ho asɛm. Ɛwom sɛ abien no nyinaa susuw anyinam ahoɔden dwumadi a amemene no yɛ de, nanso nsonsonoe da abien no ntam.
- EEG (Electroencephalogram) a Wɔde Hwɛ Mmere So: .Wɔyɛ eyi denam anyinam ahoɔden asorɔkye a w’amemene no ma ɛba bere a ɛte hɔ ara kwa a wɔkyerɛw gu kasɛt so, a biribiara nkannyan no so. Ɛte sɛ nea woretie w’amemene no ‘broadcast’.
- Evoked Potential Test: Eyi kyerɛ sɛnea amemene no yɛ n’ade ntɛmntɛm ne sɛnea ɛyɛ adwuma yiye wɔ biribi a ɛkanyan (te sɛ mfonini anaa nnyigyei) a yɛhyɛ da de ma no ho . Ɛte sɛ nea worebisa asɛm bi na woasɔ mmuae no ahwɛ.
Dɛn ne Evoked Potential Tests ahorow atitiriw?
Sɔhwɛ yi ahorow atitiriw abiɛsa na ɛwɔ hɔ. Ɛdenam wo sɛnkyerɛnne ne nea wo duruyɛfo rehwehwɛ so no, wubetumi ayɛ eyinom mu biako anaa nea ɛboro saa.
