Epidemiology & Impact (Deaths, Hospitals, Cancer, Alzheimer's etc)

COVID-19 may substantially increase the risk of developing autoimmune disease, a huge study of health records found.

A study of tens of thousands of people in Scotland found that 1 in 20 people who had been sick with COVID-19 reported not recovering at all, and another...

Two new large-scale reports, one published by Statistics Canada and the other in the Canadian Medical Association Journal, are giving a clearer picture of the long-term impacts of COVID-19 infections on Canadians and the health-care system.

People who had COVID-19 are at higher risk for a host of brain injuries a year later compared with people who were never infected by the coronavirus, a finding that could affect millions of Americans, U.S. researchers reported on Thursday.

Individuals with COVID-19 are at an increased risk for an array of neurologic disorders at 12 months, even in those who were not hospitalized during the acute phase of the infection.

September 20, 2022 — Children and adolescents who have either recovered from COVID-19 or have long COVID show persistent lung damage on MRI, according to a

The neurological deficits caused by COVID-19, which were first reported in the early months of 2020, continue to intrigue neurologists and health-care professionals worldwide. As two new studies highlight, these manifestations are frequent and are expected to increase the burden of morbidity and mortality in the acute and chronic phases of COVID-19.

COVID-19 can result in neurological manifestations and animal models could provide insights into the mechanisms. Here, the authors describe neuroinflammation, microhemorrhages and brain hypoxia in SARS-CoV-2 infected non-human primates, including in animals that don’t develop severe respiratory disease.

Viruses like HSV-1 and SARS-CoV-2 might trigger Alzheimer’s disease.

Medical experts on the basis of evidence so far disagree with claims made on social media that myocarditis following the COVID-19 vaccine is irreversible. Social media claims that “over the years,” many children diagnosed with myocarditis will die are unfounded, representatives from the Myocarditis Foundation say.

The study authors have requested the paper be retracted because the incorrect data 'vastly inflates the incidence of post-vaccine myocarditis'

Professor Massimo Hilliard and Dr Ramon Martinez-Marmol have discovered viruses such as SARS-CoV-2 can cause brain cells to fuse, initiating malfunctions that lead to chronic neurological symptoms.

Purpose Although COVID-19 typically presents with respiratory symptoms, it can also lead to severe neurological manifestations in children. While case reports of COVID-19–associated encephalopathy (including acute necrotizing encephalopathy) have increasingly appeared, gaps remain regarding optimal management strategies and outcome predictors for children with rapid-onset neurological decline. This report aims to underscore the critical need for standardized clinical approaches to severe pediatric COVID-19–related encephalopathy. Methods In this case report, We detail the case of an 8-year-old girl who presented with fever, rash, headache, and recurrent seizures. Her diagnostic workup included polymerase chain reaction (PCR) testing for SARS-CoV-2 and a range of neurological assessments: contrast-enhanced computed tomography (CT) to evaluate structural changes, transcranial Doppler ultrasound to assess intracranial hemodynamics, and electroencephalography (EEG) to monitor electrical activity. Intensive therapeutic measures—encompassing mechanical ventilation, hemodynamic support, antimicrobial agents, and corticosteroids—were initiated. In addition, a targeted narrative literature review of pediatric COVID-19–associated neurological complications was conducted to contextualize this presentation. Results The patient tested positive for COVID-19;imaging revealed brain edem, and EEG suggested brain death. Despite aggressive critical care interventions, her condition did not improve, ultimately resulting in brain death. Our review of current literature revealed several reported instances of acute necrotizing encephalopathy in pediatric COVID-19, highlighting a growing body of evidence on the potential for severe central nervous system sequelae. Conclusion This case highlights the importance of early recognition and close neurological surveillance in pediatric patients with COVID-19. Although accumulating evidence describes COVID-19–related neurological complications such as acute necrotizing encephalopathy, uncertainties persist regarding definitive treatment protocols and long-term outcomes. Greater understanding of the underlying mechanisms and standardized management pathways is imperative to improve prognosis in this vulnerable population. Clinical trial Not applicable.

Pediatric long COVID is more common than many thought, and we keep letting kids be reinfected with new variants

The calculations in the study by researchers at The University of Ottawa were used to promote the idea that the COVID-19 vaccine is unsafe for use.

Scientists have announced a major discovery that has profound importance for our understanding of brain fog and cognitive decline seen in some patients with Long COVID. The findings showed that there was disruption to the integrity of the blood vessels in the brains of patients suffering from Long COVID and brain fog. This blood vessel 'leakiness' was able to objectively distinguish those patients with brain fog and cognitive decline compared to patients suffering from Long-COVID but not with brain fog.
