I-sporadic iyinqanaba lesiganeko ngaphandle kwesibhubhane

Isiganeko esincinci sisinye seziganeko ezenza inkqubo yesibhedlele kunye nokubonakaliswa kobuthathaka obunobuthathaka benkqubo yesifo (epizootic).

Iinqhagamshelo zenkqubo yesifo

• Iziganeko eziqhelekileyo.
• Ubhubhane.
• Ukugula.

Yintoni eyenzekayo ngokukhawuleza

I-sporadic - oku kuthetha umntu, ukubhalisa kwimeko kuye kwimeko, ngokungavumelekanga.

Iziganeko eziqhelekileyo ngokuqhelekileyo zibizwa ngokuba yi-frequency of detectability yesifo esithile kwindawo yokufunda yendawo efundwayo, ixesha langoku lonyaka okanye iimpawu ezihambelana nomntu omnye.

Ngamanye amazwi, izifo ezidlulileyo ziyisifo, iimeko apho zisasazwa ngokulinganayo kuluntu kwaye azixhomekeke kukuxhomekeka kobhubhane kunye nomthombo oqhelekileyo wokusuleleka, kunye nokungenazo iimpawu zesifo esinesifafa, isifo. Imilinganiselo yokwehliswa kwesifo esincinci sisiganeko esingekho kweyeshumi kwiiwaka eziliqela labantu.

Izimbangela eziphambili zezifo ezinqabileyo

• Iinguqu ze-Neuroendocrine emzimbeni.
• Ukuphulwa kwe-embryogenesis eqhelekileyo.
• I-Pathology of pregnancy (ikakhulukazi izilonda ze-vascular).
• Utshintsho oluthile.

Imizekelo kunye neempawu

• I-goiter ye-sporadic. Esi sifo sinobubanzi kwaye sinxulumene, kunoko, ngokuphazamiseka kwe-neurohormonal eyenziwa emzimbeni. Ukuba eso sifo sibonisa ukuxhamla kunye neempawu zokubunjwa komhlaba okanye amanzi kwindawo esinikwe kuyo, ke le meko ayiyiyo imfuneko. Lo mzekelo kufuneka uhanjiswe kwi-pathology engapheliyo.
• I-spradic hemiplegic migraine. Icala le-migraine libhaliswe njenge-sporadic - le yilapho impawu zeclini yefomu enikeziweyo (i-migraine ne-aura ebonakaliswe ngu-hemiparesis, kwiimeko ezimbi kakhulu-ukuya kwi-hemiplegia ehlala kwixa elide) ayikho kwi-anamnesis yeyiphi na ilamane. I-migraine ye-sporadic kufuneka ihlukaniswe kwezinye iifom zesifo, ezinempawu ezifanayo, kunye neziphazamiso zokujikeleza kwe-cerebral, kubandakanywa nezidlulileyo.
• I-Amyotrophic lateral sclerosis. Umntu kwiimeko ezininzi kwiimeko eziphambanisayo. Esi sifo sinesimo sentsapho esasasazwa nge-autosomal path of inheritance. Ibhaliswe kwipesenti ezilishumi zamatyala kwizinga eliqhelekileyo lokungcola kwaye ineempawu ezithile ze-anatomical kunye neklinikhi ezikunceda ukuhlula ngokuhlukahlukana kwendawo.
