Yintoni i-EEG?

I-electroencephalogram (EEG) luvavanyo olusetyenziselwa ukuvavanya umsebenzi wombane kwingqondo. Iiseli zobuchopho zinxibelelana ngokuqhutywa ngamandla ombane. I-EEG ingasetyenziselwa ukunceda ekuboneni iingxaki ezinokubakho ezinxulumene nalo msebenzi.

Iitrekhi ze-EEG kunye neerekhodi zendlela yokujikeleza kwengqondo. Iidiski ezincinci zentsimbi ethe tyaba ezibizwa ngokuba zii electrode ziqhotyoshelwe entlonzeni ngeengcingo. Ii-electrode zihlalutya iimpembelelo zombane kwingqondo zize zithumele imiqondiso kwikhompyuter erekhoda iziphumo.

Iimpembelelo zombane kwi-EEG yokurekhoda zikhangeleka njengemigca ye-wavy eneencopho kunye neentlambo. Le migca ivumela oogqirha ukuba bavavanye ngokukhawuleza ukuba ngaba kukho iipateni ezingaqhelekanga. Nakuphi na ukungaqheleki kunokuba luphawu lokuxhuzula okanye ukuphazamiseka kwengqondo.

Kutheni kwenziwa i-EEG?

I-EEG isetyenziselwa ukukhangela iingxaki kwimisebenzi yombane yengqondo enokuthi inxulunyaniswe nokuphazamiseka okuthile kwengqondo. Imilinganiselo enikezwe yi-EEG isetyenziselwa ukuqinisekisa okanye ukulawula iimeko ezahlukeneyo, kubandakanya:

• Ukuphazamiseka kwengqondo (njengokuxhuzula)
• ukwenzakala entloko
• i-encephalitis (ukudumba kwengqondo)
• ithumba lobuchopho
• i-encephalopathy (isifo esibangela ukungasebenzi kwengqondo)
• iingxaki zememori
• iingxaki zokulala
• ukubetha
• Isifo sengqondo esiyingozi

Xa umntu ekwikhoma, i-EEG inokwenziwa ukumisela inqanaba lomsebenzi wobuchopho. Uvavanyo lunokusetyenziselwa ukubeka esweni umsebenzi ngexesha lotyando lobuchopho.

Ngaba bukhona ubungozi obunxulunyaniswa ne-EEG?

Akukho bungozi buhambelana ne-EEG. Uvavanyo alunantlungu kwaye lukhuselekile.

Ezinye ii-EEG azibandakanyi izibane okanye ezinye izinto ezikhuthazayo. Ukuba i-EEG ayivelisi nakuphi na ukungaqheleki, izinto ezinje ngezibane ze-strobe, okanye ukuphefumla ngokukhawuleza kunokongezwa ukunceda ukwenza nakuphi na ukungaqheleki.

Xa umntu enesathuthwane okanye esinye isifo sokuthimba, inkuthazo eboniswe ngexesha lovavanyo (njengokukhanya okudanyazayo) kunokubangela ukuxhuzula. Igcisa elenza i-EEG liqeqeshelwe ukulawula ngokukhuselekileyo nayiphi na imeko enokwenzeka.

Ndiyilungiselela njani i-EEG?

Ngaphambi kovavanyo, kuya kufuneka uthathe la manyathelo alandelayo:

Hlamba iinwele zakho ngobusuku obungaphambi kwe-EEG, kwaye ungazibeki naziphi na iimveliso (ezinje ngezitshizi okanye iigels) kwizinwele zakho ngosuku lovavanyo.

Buza ugqirha wakho ukuba ngaba uyekile ukuthatha nawaphi na amayeza ngaphambi kovavanyo. Kuya kufuneka wenze uluhlu lwamayeza akho kwaye ulinike uchwepheshe owenza i-EEG.

Kuphephe ukutya okanye ukusela nantoni na enecaffeine kangangeeyure ezisibhozo phambi kovavanyo.

Ugqirha wakho unokukucela ukuba ulale kancinci kangangoko ngobusuku obuphambi kovavanyo ukuba kufuneka ulale ngexesha le-EEG. Unokunikwa i-sedative ukukunceda uphumle kwaye ulale ngaphambi kokuba uvavanyo luqale.

Emva kokuba i-EEG iphelile, ungaqhubeka nomsebenzi wakho wesiqhelo. Nangona kunjalo, ukuba unikwe umthomalalisi, amayeza aya kuhlala kwinkqubo yakho okwethutyana. Oku kuthetha ukuba kuyakufuneka uze nomnye umntu ukuze bakugoduse emva kovavanyo. Kuya kufuneka uphumle kwaye uphephe ukuqhuba de iyeza liphele.

Yintoni endinokuyilindela ngexesha le-EEG?

I-EEG ilinganisa iimpembelelo zombane kwingqondo yakho ngokusebenzisa ii-electrode ezininzi eziqhotyoshelwe entlonzeni yakho. I-electrode ngumqhubi apho kungena khona okanye kushiya umbane. Ukudlulisa ulwazi kwi-electrode ukusuka kwingqondo yakho ukuya kumatshini olinganisa nokurekhoda idatha.

Iingcali ezikhethekileyo zilawula ii-EEG ezibhedlele, iiofisi zikagqirha, kunye neelebhu. Uvavanyo luhlala luthatha imizuzu engama-30 ukuya kwengama-60 ukulugqiba, kwaye lubandakanya la manyathelo alandelayo:

Uya kulala phantsi ngomqolo kwisitulo esingqengqile okanye ebhedini.

Ingcali iya kuyilinganisela intloko yakho kwaye iphawule apho ungabeka khona ii-electrode. La mabala akhuhliwe ngekhrim ekhethekileyo enceda ii-electrode zifumane ukufundwa okusemgangathweni ophezulu.

Ingcali iya kubeka i-gel yokuncamathelisa kwi-electrode ezili-16 ukuya kwezingama-25, kwaye uzincamathisele kumachaphaza entlonzeni yakho.

Nje ukuba uvavanyo luqale, ii-electrode zithumela idatha yombane ukusuka kwingqondo yakho ukuya kumatshini wokurekhoda. Lo matshini uguqula iimpembelelo zombane kwiipateni ezibonakalayo ezivela kwiscreen. Ikhompyuter igcina ezi patheni.

Ingcali inokuyalela ukuba wenze izinto ezithile ngelixa uvavanyo lusaqhubeka. Banokucela ukuba ulale ungathethi, vala amehlo, uphefumle nzulu, okanye ujonge izinto (ezinjengesibane esidanyazayo okanye umfanekiso).

Emva kokuba uvavanyo lugqityiwe, igcisa liya kususa ii-electrode kwisikhumba sakho.

Ngexesha lovavanyo, umbane omncinci kakhulu udlula phakathi kwee-electrode kunye nolusu lwakho, ke uya kuziva ungonwabi.

Ngamanye amaxesha, umntu unokufumana iiyure ezingama-24 ze-EEG. Ezi EEG zisebenzisa ividiyo ukubamba imisebenzi yokuthimba. I-EEG inokubonisa ukungaqheleki nokuba ukubanjwa akwenzeki ngexesha lovavanyo. Nangona kunjalo, ayisoloko ibonisa ukungaqheleki okudlulileyo okunxulumene nokubanjwa.

Zithetha ntoni iziphumo zovavanyo ze-EEG?

Ugqirha wemithambo-luvo (umntu ogxile kukuphazamiseka kwenkqubo yemithambo-luvo) utolika ushicilelo oluvela kwi-EEG emva koko athumele iziphumo kugqirha wakho. Ugqirha wakho unokucwangcisa ixesha lokudibana nawe ukuze ugqibe iziphumo zovavanyo nawe.

Iziphumo eziqhelekileyo

Umsebenzi wombane kwingqondo ubonakala kwi-EEG njengepateni yamaza. Amanqanaba ahlukeneyo okuqonda, njengokulala kunye nokuvuka, anoluhlu oluthile lwamaxesha amaza ngomzuzwana athathwa njengesiqhelo. Umzekelo, iipateni zamaza zihamba ngokukhawuleza xa uvukile kunokuba ulele. I-EEG iya kubonisa ukuba ubungakanani bamaza okanye iipateni ziqhelekile. Umsebenzi oqhelekileyo uthetha ukuba awunayo ingxaki yengqondo.

Iziphumo ezingaqhelekanga

Iziphumo ezingaqhelekanga ze-EEG zinokubangelwa:

• isifo sokuwa okanye esinye isifo sokuthimba
• ukopha ngokungaqhelekanga okanye ukopha
• ingxaki yokulala
• i-encephalitis (ukudumba kwengqondo)
• ithumba
• inyama efileyo ngenxa yokuvalwa kokuhamba kwegazi
• migraines
• utywala okanye iziyobisi
• ukwenzakala entloko

Kubaluleke kakhulu ukuba uxoxe ngeziphumo zakho zovavanyo kunye nogqirha wakho. Ngaphambi kokuba uphonononge iziphumo, kunokuba luncedo ukubhala phantsi nayiphi na imibuzo onokufuna ukuyibuza. Qiniseka ukuba uyathetha ukuba kukho into malunga neziphumo zakho ongayiqondiyo.
