\nCercet\u0103torii italieni au f\u0103cut \u201eo hart\u0103\u201d a afec\u0163iunilor neurologice suferite de pacien\u0163ii Covid, de la accident vascular cerebral la cefalee. Cea mai frecvent\u0103 tulburare este alterarea combinat\u0103 a sim\u0163ului olfactiv \u015fi gustativ, urmat\u0103 de confuzia mental\u0103, pierderea aten\u0163iei \u015fi a memoriei.<\/p>\n
\n\u00cencep\u00e2nd cu primii pacien\u0163i din Wuhan \u015fi p\u00e2n\u0103 \u00een prezent, medicii din \u00eentreaga lume au constatat complica\u0163ii neurologice multiple \u015fi adesea prelungite la cei afecta\u0163i de Covid. Nu doar pierderea sim\u0163ului mirosului \u015fi a gustului, unul dintre semnalele de alarm\u0103 \u015fi un simptom larg r\u0103sp\u00e2ndit al infec\u0163iei, ci \u015fi probleme mai grave: de la encefalopatie la accident vascular cerebral.<\/p>\n
\nStudiul va fi prezentat la Congresul Mondial de Neurologie, din 3-7 octombrie, organizat de Federa\u0163ia Mondial\u0103 de Neurologie \u00een parteneriat cu Societatea Italian\u0103 de Neurologie, conform ANSA.<\/p>\n
\nAu fost implica\u0163i 2500 de pacien\u0163i Covid, at\u00e2t spitaliza\u0163i, c\u00e2t \u015fi trata\u0163i acas\u0103.<\/p>\n
\nStudiul arat\u0103 c\u0103 cea mai frecvent\u0103 tulburare neurologic\u0103 este alterarea combinat\u0103 a sim\u0163ului olfactiv \u015fi gustativ (la aproximativ 40% dintre pacien\u0163i). Durata acestui simptom este mai mare de o lun\u0103 \u00een 50% din cazuri \u015fi ajunge la peste 6 luni \u00een 20% din cazuri.<\/p>\n
\nO a doua tulburare, frecvent\u0103 (aproximativ 25% dintre pacien\u0163i), este encefalopatia acut\u0103, adic\u0103 o stare de confuzie mental\u0103, pierderea aten\u0163iei \u015fi a memoriei, agita\u0163ie \u015fi chiar alterarea st\u0103rii de con\u015ftien\u0163\u0103 \u015fi com\u0103. Aceast\u0103 afec\u0163iune are cauze multiple, \u00eencep\u00e2nd cu o oxigenare cerebral\u0103 deficitar\u0103, dar \u00een unele cazuri este legat\u0103 de o inflama\u0163ie cerebral\u0103 (encefalit\u0103).<\/p>\n
\nMul\u0163i pacien\u0163i neuro-COVID (aproximativ 20%) au suferit un accident vascular cerebral ischemic, fie concomitent, fie imediat dup\u0103 infec\u0163ia cu Covid, dar leg\u0103tura cauz\u0103-efect \u00eentre infec\u0163ia cu Covid \u015fi accidentul vascular cerebral este \u00eenc\u0103 dezb\u0103tut\u0103. Aproape to\u0163i ace\u015fti pacien\u0163i au factori de risc vascular clasici, iar studiile sugereaz\u0103 c\u0103 infec\u0163ia a fost un factor declan\u015fator al trombozei arteriale cerebrale.<\/p>\n
\nCefaleea asociat\u0103 cu Covid este frecvent\u0103 \u015fi nu \u00eentotdeauna de scurt\u0103 durat\u0103. \u00cen aproximativ 50% din cazuri devine cronic\u0103 \u015fi dureaz\u0103 mai mult de 2 s\u0103pt\u0103m\u00e2ni, \u00een timp ce \u00een aproape 20% din cazuri dureaz\u0103 mai mult de 3 luni.<\/p>\n
\nTulbur\u0103rile cognitive post-Covid fac parte din “sindromul long-Covid” \u015fi au fost definite \u015fi ca “cea\u0163\u0103 cognitiv\u0103”.<\/p>\n
\nNu sunt rare (aproximativ 10% dintre pacien\u0163i), dar amploarea tulbur\u0103rii este aproape \u00eentotdeauna modest\u0103 (nu atinge criteriile unei “demen\u0163e”, ci doar ale unei tulbur\u0103ri cognitive u\u015foare) \u015fi cu o important\u0103 component\u0103 emo\u0163ional\u0103, dar \u015fi cognitiv\u0103. Durata medie este de aproximativ 3 luni \u015fi se rezolv\u0103 spontan \u00een 6 luni \u00een aproape toate cazurile.<\/p>\n
\nPotrivit oamenilor de \u015ftiin\u0163\u0103, principalele cauze ale tulbur\u0103rilor neurologice sunt deficitul de oxigen cerebral, inflama\u0163ia creierului sau tromboza arterelor \u015fi venelor cerebrale, toate acestea fiind posibile consecin\u0163e ale unei infec\u0163ii cu Covid.<\/p>\n
\n\u00cen cadrul Congresului, studiul Italian va fi comparat cu studii similare realizate de alte societ\u0103\u0163i neurologice europene.<\/p>\n","protected":false},"excerpt":{"rendered":"
