AI Article Synopsis

  • Acute mild SARS-CoV-2 infections can result in a persistent cognitive issue referred to as "COVID fog."
  • Researchers, including Fernández-Castañeda, discovered that glial cell dysregulation may play a role in this cognitive impairment.
  • This glial dysfunction may lead to problems in neural circuits, contributing to the cognitive challenges faced by those with long COVID.

Article Abstract

Acute mild respiratory SARS-CoV-2 infection can lead to a more chronic cognitive syndrome known as "COVID fog." New findings from Fernández-Castañeda et al. reveal how glial dysregulation and consequent neural circuit dysfunction may contribute to cognitive impairments in long COVID.

Amidst growing concerns over COVID-19 aftereffects like fatigue and cognitive issues, NRICM101, a traditional Chinese medicine, has shown promise. Used by over 2 million people globally, it notably reduces hospitalizations and intubations in COVID-19 patients. To explore whether NRICM101 could combat COVID-19 brain fog, we tested NRICM101 on hACE2 transgenic mice administered the S1 protein of SARS-CoV-2, aiming to mitigate S1-induced cognitive issues by measuring animal behaviors, immunohistochemistry (IHC) staining, and next-generation sequencing (NGS) analysis.

Background: The impact of vaccination on the type and risk of specific post-COVID symptoms after Omicron infection is not clear. We aimed to investigate the excess risk and patterns of 22 symptoms 3-5 months after Omicron infection, comparing uninfected and infected subjects with and without recent booster vaccination.

Methods: We conducted a population-based prospective study based on four questionnaire-based cohorts linked to national health registries.

Cerebromicrovascular mechanisms contributing to long COVID: implications for neurocognitive health.

Long COVID (also known as post-acute sequelae of SARS-CoV-2 infection [PASC] or post-COVID syndrome) is characterized by persistent symptoms that extend beyond the acute phase of SARS-CoV-2 infection, affecting approximately 10% to over 30% of those infected. It presents a significant clinical challenge, notably due to pronounced neurocognitive symptoms such as brain fog. The mechanisms underlying these effects are multifactorial, with mounting evidence pointing to a central role of cerebromicrovascular dysfunction.

Persistent symptoms after COVID-19 constitute the long COVID syndrome, also called post-acute sequelae of SARS-CoV-2 infection (PASC). COVID-19 vaccines reduce the gravity of ensuing SARS-CoV-2 infections. However, whether vaccines also have an impact on PASC remain unknown.

Introduction: The SARS-CoV-2 pandemic has caused global devastations in social, economic and health systems of every nation, but disproportionately of nations in Africa. In addition to its grave effects on the global systems, there is continuation or development of new symptoms among individuals who have contracted the virus, with the potential to further stress the health systems on the continent. Therefore, the aim of this scoping review was to collate and summarise the existing research evidence on the prevalence and health effects of post-COVID-19 conditions in Africa.
