Resumo

Introdução. Este artigo aborda as implicações neurocognitivas da síndrome pós-COVID-19, com ênfase na neuroinflamação hipocampal e seu possível impacto nos distúrbios de memória. Explorando as evidências existentes sobre a relação entre a infecção por COVID-19 e as alterações neurocognitivas, busca-se aprofundar a compreensão desses fenômenos, destacando a importância de pesquisas mais detalhadas nesse campo crítico da saúde neurológica. Objetivo. Analisar as repercussões neurocognitivas na síndrome pós-COVID-19, com foco específico na neuroinflamação hipocampal e distúrbios de memória, visando aprofundar a compreensão dos mecanismos patológicos associados. Método.  A pesquisa foi conduzida utilizando estratégias de busca em bases de dados como MEDLINE/PubMed, Science Direct e Web of Science. Os termos de busca seguiram padrões MeSH e DeCS. A questão norteadora foi sobre o impacto da síndrome pós-COVID-19 nas funções neurocognitivas, com foco na neuroinflamação hipocampal e distúrbios de memória. Resultados. A ativação microglial no hipocampo, associada ao comprometimento cognitivo por vírus, pode explicar sintomas neuropsiquiátricos em sobreviventes de COVID-19. Estudos indicam que a inflamação sistêmica, presente na sepse grave, pode desencadear comprometimento cognitivo e neurodegeneração, possivelmente compartilhando semelhanças com a COVID-19.   Conclusão. Compreender as lesões cerebrais causadas pela COVID-19 pode guiar intervenções terapêuticas, incluindo moduladores de citocinas, para mitigar queixas neuropsiquiátricas. Melhorar as complicações pós-COVID-19 reduzirá o impacto da doença, enquanto a neuropatologia pode fornecer insights valiosos para outras condições neurodegenerativas.
