Objective To investigate neurologic manifestations of post‐acute sequelae SARS‐CoV‐2 infection (Neuro‐PASC) in post‐hospitalization Neuro‐PASC (PNP) and non‐hospitalized (NNP) patients across the adult lifespan. Methods Cross‐sectional study first consecutive 200 PNP 1,100 NNP evaluated at a Neuro‐coronavirus disease 2019 (COVID‐19) clinic between May 2020 March 2023. Patients were divided into younger (18–44 years), middle‐age (45–64 older (65+ years) age groups. Results Younger individuals accounted for 142 (71%) 995 1100 (90.5%) patients. Significant age‐related differences frequencies comorbidities abnormal findings demonstrated higher prevalence Conversely, 10 months from COVID‐19 onset, we found significant symptoms indicating lower prevalence, therefore, symptom burden, individuals. Moreover, there subjective impression fatigue (median [interquartile range (IQR)] patient‐reported outcomes measurement information system [PROMIS] score: 64 [57–69], 63 [57–68], 60.5 [50.8–68.3]; p = 0.04) sleep disturbance [IQR] PROMIS 57 [51–63], 56 [53–63], 54 [46.8–58]; 0.002) group, commensurate with impairment quality life (QoL) among Finally, objective executive function National Institutes Health [NIH] toolbox 48 [35–63], 49 [38–63], 54.5 [45–66.3]; 0.01), working memory NIH 47 [40–53], 50 [44–57], [43–58]; 0.0002) patients, worst performance coming group.

The SAR-CoV-2 virus has evolved to co-exist with human hosts, albeit at a substantial energetic cost resulting in post-infection neurological manifestations [Neuro-post-acute sequelae of SARS-CoV-2 infection (PASC)] that significantly impact public health and economic productivity on global scale. One the main molecular mechanisms responsible for development Neuro-PASC, individuals all ages, is formation inadequate proteolysis/clearance phase-separated amyloid crystalline aggregates—a hallmark feature aging-related neurodegenerative disorders. Amyloidogenesis during viral persistence natural, inevitable, protective defense response exacerbated by SARS-CoV-2. Acting as chemical catalyst, accelerates hydrophobic collapse heterogeneous nucleation amorphous amyloids into stable β-sheet aggregates. clearance aggregates most effective slow wave sleep, when high levels adenosine triphosphate (ATP)—a biphasic modulator biomolecular condensates—and melatonin are available solubilize removal. dysregulation mitochondrial dynamics SARS-CoV-2, particular fusion fission homeostasis, impairs proper distinct subpopulations can remedy challenges created diversion substrates away from oxidative phosphorylation towards glycolysis support replication maintenance. subsequent reduction ATP inhibition synthesis sleep results incomplete brain aggregates, leading commonly associated age-related Exogenous not only prevents dysfunction but also elevates production, effectively augmenting solubilizing effect moiety ensure timely, optimal disaggregation pathogenic prevention attenuation Neuro-PASC.

In the intricate realm of interactions between hosts and pathogens, Toll-like receptors (TLRs), which play a crucial role in innate immune response, possess ability to identify specific molecular signatures. This includes components originating from pathogens such as SARS-CoV-2, well resulting damage-associated patterns (DAMPs), endogenous molecules released after cellular damage. A developing perspective suggests that TLRs central neuroinflammation, fundamental factor neurodegenerative conditions like Alzheimer’s Parkinson’s disease (PD). comprehensive review consolidates current research investigating potential interplay TLRs, their signaling mechanisms, processes neurodegeneration following SARS-CoV-2 infection with an aim elucidate involvement long-term neurological complications COVID-19 explore targeting means implementing intervention strategies for prevention or treatment COVID-19-associated brain outcomes.

ABSTRACT The human genome comprises 8% of endogenous retroviruses (HERVs). Though HERVS contribute to physiological functions, copies retained pathogenic potential. HERV-W ENV protein was shown expressed in patients with worse COVID-19 symptoms and post-COVID syndrome. A significant detection the mRNA encoding from B cells RNAseq reads obtained peripheral blond mononuclear cells. This data stratified increased or post-acute sequelae (long COVID) after 3 months. ENV-U3R RNA confirmed display best alignment chromosome X ERVWE2 locus. However, a stop codon precluding its translation re-addressed recent understandings ribosome readthrough mechanisms. Experimental results evidenced that this HERV gene can effectively express full-length presence molecules allowing via mechanism at level. Results not only confirm origin these patients, but show for first time how defective copy be translated into complete when specific factors make it possible present proof concept now requires further studies identify involved newly understood mechanism, following SARS-CoV-2 exposure.

Individuals recovering from COVID-19 may experience persistent impairment in verbal memory performance, potentially due to illness-related hippocampal injury. Although dysfunction is central schizophrenia, the interactions between this vulnerability and remain unclear, with no imaging studies addressing issue to-date. To explore gap generate hypotheses for future research, we adopted a multiple case study approach. Two pairs of individuals an ICD-10 diagnosis schizophrenia were selected, each consisting one positive anamnesis without. We calculated Reliable Change Index estimate clinical significance performance changes, annualized change rates volumes assessed against normative data. Compared their matches, cases did not show mutually consistent changes performance: experienced significant decline learning, while other showed general normalization test scores. Left comparatively slowed increase, right hippocampi decreased volume, although these atrophy exceed those expected population samples. Based on findings, hypothesize that alone does lead schizophrenia. Instead, relationship diseases depend additional factors. Our differed body mass index, systolic blood pressure, sex, phase illness, whole grey matter volume trajectories, leading us variables represent predictors or moderators relationship.
