Doença dos tiques: aspectos genéticos e neuroquímicos atuais

Abstract: RESUMO-Após breve revisão dos dados históricos, do conceito, do quadro clínico e dos critérios para o diagnóstico, analisamos os principais aspectos genéticos e neuroquímicos atuais dos tiques e da síndrome de Gilles de La Tourette. Dados epidemiológicos sugerem que todo tique seja de natureza orgânica, a maioria de origem genética, e que obedecem a transmissão autossômica dominante com penetrância aproximada de 100%. Ressaltamos, ainda, os recentes estudos imuno-histoquímicos, particularmente os que se refere… Show more

“…A síndrome de La Tourette (incoordenação motora, ecolalia, coprolalia e tiques) é transtorno relacionado às alterações do metabolismo e da neurotransmissão dopaminérgica, envolvendo circuitos neuronais frontais-subcorticais 21 . Há indicação cirúrgica em alguns casos, embora na maioria seja limitada à infância.…”

“…Pre or post events can also be connected to TS, where the gravity of the stressors during the pregnancy has been analyzed like factors that could contribute to the development of tic disorders and the pathogenesis of the disease (9,17). This way, because of the fact of not be determined, still, all the involved factors in the abnormal neurological condition of TS, it cannot exclude the possibility of the same to be a syndrome of multiple causes.…”
