Long COVID represents the constellation of post-acute and long-term health effects caused by SARS-CoV-2 infection; it is a complex, multisystem disorder that can affect nearly every organ system be severely disabling. The cumulative global incidence long around 400 million individuals, which estimated to have an annual economic impact approximately $1 trillion-equivalent about 1% economy. Several mechanistic pathways are implicated in COVID, including viral persistence, immune dysregulation, mitochondrial dysfunction, complement endothelial inflammation microbiome dysbiosis. devastating impacts on individual lives and, due its complexity prevalence, also has major ramifications for systems economies, even threatening progress toward achieving Sustainable Development Goals. Addressing challenge requires ambitious coordinated-but so far absent-global research policy response strategy.

Cerebromicrovascular mechanisms contributing to long COVID: implications for neurocognitive health

GeroScience, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 7, 2025

Abstract 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 infection, affecting approximately 10% to over 30% those infected. It presents a significant clinical challenge, notably due pronounced neurocognitive such brain fog. The mechanisms underlying these effects are multifactorial, with mounting evidence pointing central role cerebromicrovascular dysfunction. This review investigates key pathophysiological contributing cerebrovascular dysfunction in long and their impacts on health. We discuss how endothelial tropism direct vascular trigger dysfunction, impaired neurovascular coupling, blood–brain barrier disruption, resulting compromised cerebral perfusion. Furthermore, appears induce mitochondrial enhancing oxidative stress inflammation within cells. Autoantibody formation following also potentially exacerbates injury, chronic ongoing compromise. These factors collectively contribute emergence white matter hyperintensities, promote amyloid pathology, may accelerate neurodegenerative processes, including Alzheimer’s disease. emphasizes critical advanced imaging techniques assessing health need for targeted interventions address complications.

Since the emergence of SARS-CoV-2 virus in 2019, nearly 700 million COVID-19 cases and 7 deaths have been reported globally. Despite most individuals recovering within four weeks, Center for Disease Control (CDC) estimates that 7.5% to 41% develop post-acute infection syndrome (PAIS), known as 'Long COVID'. This review provides current statistics on Long COVID's prevalence, explores hypotheses concerning epidemiological factors, such age, gender, comorbidities, initial severity, vaccine interactions, delves into potential mechanisms, including immune responses, viral persistence, gut dysbiosis. Moreover, we conclude women, advanced non-vaccination, low socioeconomic status all appear be risk factors.

The share of the elderly population is growing worldwide as life expectancy increases. Immunosenescence and comorbidities increase infectious diseases’ morbidity mortality in older adults. Here, we aimed to summarize latest findings on vaccines for against herpes zoster, influenza, respiratory syncytial virus (RSV), COVID-19, pneumococcal disease examine vaccine recommendation differences this age group Europe United States. PubMed was searched using keywords “elders” “vaccine” alongside disease/pathogen question paraphrased or synonymous terms. Vaccine recommendations were also sought European US Centers Disease Control Prevention databases. Improved vaccines, tailored elderly, mainly by novel adjuvants increasing antigen concentration, are now available. Significant exist between immunization policies, especially countries, terms recipient’s age, number doses, vaccination schedule, implementation (mandatory recommended). Understanding factors that influence immune response may help design offer long-term protection vulnerable group.
