У многих пациентов после перенесенной коронавирусной инфекции, помимо характерного постинфекционного астенического синдрома, развивается комплекс когнитивных расстройств с преобладанием нарушений исполнительских функций и кратковременной памяти, иногда в виде ощущений «мозгового тумана». Эти нарушения встречаются у значительного числа переболевших, имеют неоднородную структуру, комплексный механизм отличаются длительным персистирующим характером. Их особенность заключается отсутствии четкой взаимосвязи симптомами круга, значительной распространенности по сравнению другими постинфекционными нарушениями требует разработки унифицированных подходов к их оценке учетом индивидуальных особенностей пациентов. Существует потребность продолжении масштабных исследований, посвященных оптимизации комплексной нейрореабилитации постковидными расстройствами, эффективности безопасности потенциально эффективных средств восстановления стимуляции функций. средства должны влиять на механизмы системного воспаления, гемореологические параметры оказывать благоприятные нейропротекторные эффекты. Остается актуальным вопрос индивидуализированного прогноза профилактики последствий инфекции. Many patients after the COVID-19 infection, in addition to postinfectious asthenia, develop a complex of cognitive disorders with predominance impaired executive functions and short-term memory, sometimes form "brain fog". Cognitive impairment occurs significant number patients. They have heterogeneous structure mechanism, usually characterized by long-term persistence. Their specific features are lack clear relationship symptoms as well prevalence compared other post-infectious disorders. All this requires development unified approaches their assessment, considering individual characteristics There is need continue large-scale studies optimize neurorehabilitation post-COVID-19 disorders, evaluate efficacy safety potentially effective therapeutic agents for restoration stimulation functions. These pharmacological should control mechanisms systemic inflammation, hemorheological parameters provide favorable neuroprotective effects. The individualized prognosis prevention consequences coronavirus infection remains an important problem.

The present study aims to provide a critical overview of the literature on relationships between post-acute COVID-19 infection and cognitive impairment, highlighting limitations confounding factors. A systematic search articles published from 1 January 2020 July 2022 was performed in PubMed/Medline. We followed Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) guidelines. Only studies using validated instruments assessment impairment were included. Out 5515 screened records, 72 met inclusion criteria. available evidence revealed presence executive functions, speed processing, attention memory subjects recovered COVID-19. However, several reviewed should be highlighted: most small samples, not stratified by severity disease age, used as cross-sectional or short-term longitudinal design provided limited different domains.

The global coronavirus pandemic has significantly impacted public health and been a research subject since its emergence in 2019. acute phase of the disease leads to pulmonary non-pulmonary manifestations, which some individuals may progress long-lasting symptoms. In this article, we conducted narrative review current literature summarize knowledge regarding long COVID syndrome children, focusing on cognitive included search three databases (PubMed, Embase, Web Science) using key phrases “post COVID-19 pediatric”, “long “mental children”, “COVID-19 symptoms”. A total 102 studies were included. revealed that main long-term symptoms following memory concentration deficits, sleep disturbances, psychiatric states such as anxiety stress. addition direct physiological effects viral infection, there are psychological, behavioral, social factors contributing impairment, should be addressed pediatric population. high prevalence neurocognitive children emphasizes importance understanding mechanisms nervous system involvement.

Previous research and clinical reports have shown that some individuals after COVID-19 infection may demonstrate symptoms of so-called brain fog, manifested by cognitive impairment disorganization in behavior. Meanwhile, several other conditions, related to intellectual function, a specific pattern changes electric activity, as recorded quantitative electroencephalography (QEEG) has been documented. We hypothesized, post-COVID the subjective complaints be accompanied objective QEEG profile. In order test this hypothesis, we performed an exploratory study on academic staff our University with previous records originating pre-COVID-19 era. Among them, 20 subjects who revealed neurological problems sphere (confirmed covid fog/brain fog specialist) were identified. those individuals, was performed. observed, opposite baseline records, increased Theta Alpha well more intensive sensimotor rhythm (SMR) C4 (right hemisphere) relation C3 (left hemisphere). Moreover, visible increase Beta 2 SMR both hemispheres could Summarizing, clear change activity patterns previously not affected now suffering from post-COVID-19 fog. These preliminary results warrant further interest delineating their background. Here, neuroinflammation psychological stress, Sars-CoV2-infection considered. Based observation, relevance examination supportive tool for workup monitoring treatment effects is also explored.

Background: There is an urgent need to better understand the mechanisms underlying acute and long-term neurological symptoms after COVID-19. Neuropathological studies can contribute a understanding of some these mechanisms. Methods: We conducted detailed postmortem neuropathological analysis 32 patients who died due COVID-19 during 2020 2021 in Austria. Results: All cases showed diffuse white matter damage with microglial activation variable severity, including one case hemorrhagic leukoencephalopathy. Some revealed mild inflammatory changes, olfactory neuritis (25%), nodular brainstem encephalitis (31%), cranial nerve (6%), which were similar those observed non-COVID-19 severely ill patients. One previously immunosuppressed patient developed herpes simplex encephalitis. Acute vascular pathologies (acute infarcts 22%, thrombosis 12%, hypoxic–ischemic brain 40%) pre-existing small vessel diseases (34%) frequent findings. Moreover, silent neurodegenerative elderly persons common (AD neuropathologic changes 32%, age-related neuronal glial tau Lewy bodies 9%, argyrophilic grain disease 12.5%, TDP43 pathology 6%). Conclusions: Our results support previous findings apparently multifactorial most likely indirect context SARS-CoV-2 infection rather than virus-specific damage, they are line recent experimental data on SARS-CoV-2-related activation, cytokine release.

Abstract We aimed to characterize the cognitive profile of post-acute COVID-19 syndrome (PACS) patients with complaints, exploring influence biological and psychological factors. Participants confirmed SARS-CoV-2 infection complaints ≥ 8 weeks phase were included. A comprehensive neuropsychological battery (NPS) health questionnaires administered at inclusion 1, 3 6 months. Blood samples collected each visit, MRI scan baseline months, and, optionally, cerebrospinal fluid. Cognitive features analyzed in relation clinical, neuroimaging, biochemical markers follow-up. Forty-nine participants, a mean time from symptom onset 10.4 showed attention-executive function (69%) verbal memory (39%) impairment. Apathy (64%), moderate-severe anxiety (57%), severe fatigue (35%) prevalent. Visual (8%) correlated total gray matter (GM) subcortical GM volume. Neuronal damage inflammation within normal limits. Over time, test scores, depression, apathy, indexes, fluid biomarkers remained stable, although fewer participants (50% vs. 75.5%; p = 0.012) exhibited abnormal evaluations Altered attention/executive memory, common PACS, persisted most subjects without association structural abnormalities, elevated cytokines, or neuronal markers.
