MRI Study Reveals High Incidence of Brain Lesions in Kids During Omicron/ Long COVID Cognitive Impact in Children : A 12-Month Study
High Incidence of Cerebrovascular Lesions in Pediatric COVID-19 Patients During Omicron Outbreak: MRI Study
A recent study, published on February 26, 2024, has revealed a high incidence of cerebrovascular lesions in pediatric COVID-19 patients during Omicron. This retrospective case series highlights significant MRI findings and underscores the diverse neurological impact of COVID-19 on children and adolescents.
Key Findings:
MRI Abnormalities: 48.4% of pediatric patients with post-COVID-19 neurological symptoms showed MRI abnormalities.
Types of Lesions: Predominantly encephalitis/encephalopathy (73.3%), with notable findings including focal diffusion-weighted imaging (DWI) hyperintensity in the cerebral cortex and thalamus, diffuse cortical T2/DWI hyperintensity, and lesions in the medulla, pons, cerebellum, and splenium of corpus callosum.
Vascular Abnormalities: 80% of patients with MRI abnormalities exhibited vascular issues, mainly affecting the middle cerebral arteries.
Neurological Manifestations: The spectrum of symptoms ranged from seizures to Alice in Wonderland syndrome.
In-Depth Analysis
Background
The spread of the Omicron variant of COVID-19 has been associated with a significant increase in pediatric hospitalizations. Alongside respiratory symptoms, changes in neurological symptoms have been reported. This study aimed to characterize the changes observed in MRI scans of children with neurological symptoms during the acute phase of infection, focusing on cerebral vasculature changes.
Methods
The study retrospectively analyzed clinical and MRI data from 31 pediatric patients in Taiwan who exhibited neurological symptoms and MRI abnormalities during the Omicron outbreak from April 2022 to June 2022. The researchers collected data on clinical manifestations and calculated the proportion of patients with vascular abnormalities.
Results
Among the 31 pediatric patients studied, nearly half (48.4%) showed MRI abnormalities. The most common abnormality was encephalitis/encephalopathy (73.3%). Other significant MRI findings included focal DWI hyperintensity in the cerebral cortex and thalamus, diffuse cortical T2/DWI hyperintensity, and lesions in the medulla, pons, cerebellum, and splenium of the corpus callosum. Vascular abnormalities were present in 80% of the patients with MRI abnormalities, predominantly affecting the middle cerebral arteries.
The range of neurological manifestations was broad, with some children experiencing seizures and others presenting with Alice in Wonderland syndrome, highlighting the varied impact of COVID-19 on the pediatric population.
Conclusion
This study demonstrates a high incidence of cerebrovascular lesions in pediatric patients with neurological involvement during the Omicron variant infection. The findings suggest that vascular involvement plays a crucial role in the neurological manifestations observed in these patients. Clinicians should be aware of the potential for significant cerebrovascular changes in children infected with COVID-19.
Cognitive Impairment in Children Post-COVID: Key Findings and Implications
The prevalence and co-occurrence of cognitive impairment in children and young people up to 12 months after infection with the SARS-CoV-2 Omicron variant have become a pressing concern. A recent study, published on May 10, 2024, sheds light on the long-term cognitive effects experienced by young people post-infection.
Key Findings:
12 Months Post-Infection: Approximately 7% of children and young people report experiencing 'brain fog' or fluctuating cognitive impairment a year after infection.
Persistent Cognitive Impairment: 2.4% of children and young people experienced ongoing cognitive impairment at 3, 6, and 12 months post-infection.
Demographic Variations: Cognitive impairment was more commonly reported among females, individuals of white ethnicity, and older children at the time of their first infection.
Co-occurring Issues: Cognitive impairment is often accompanied by poor mental health, fatigue, and sleep problems. (Long COVID in Kids)
In-Depth Analysis
Background
Cognitive impairment, often described as 'brain fog,' is a frequently reported symptom following SARS-CoV-2 infection. Despite its prevalence, there remain significant gaps in our understanding of its long-term effects, especially in children and young people (CYP). This study aimed to fill these gaps by examining the prevalence and characteristics of cognitive impairment in CYP 12 months post-infection and exploring its correlation with other health issues.
Prevalence and Characteristics
The study found that about 7% of CYP reported cognitive impairment 12 months after infection with the Omicron variant. This impairment was not constant for all; some children experienced fluctuations, with persistent impairment observed in 2.4% at the 3-, 6-, and 12-month marks. The likelihood of reporting cognitive impairment was higher among females, children of white ethnicity, and those older at the time of infection.
Co-occurrence with Other Health Issues
Cognitive impairment did not exist in isolation. Children experiencing 'brain fog' also reported poorer mental health, increased fatigue, and sleep problems. These findings highlight the intertwined nature of cognitive and mental health post-COVID, underscoring the need for comprehensive care approaches.
Conclusion
The fluctuating nature of cognitive impairment in CYP up to a year post-infection with SARS-CoV-2 indicates a need for sustained monitoring and support. Healthcare providers should be aware of the potential for cognitive impairment and its association with sleep disturbances, mental fatigue, and emotional issues. Addressing these co-occurring problems is crucial for the holistic well-being of affected children and young people.
These studies and the many others TACT has previously highlighted underscore the significant and alarming risks that COVID-19 poses to children, with effects that persist months and potentially years after the initial infection. What impact are repeated infections having on children's brains? While we don't yet fully grasp the extent of the damage, we do know that it is affecting far too many children. Why is society turning a blind eye to the impact of this disease? We must raise awareness about the dangers repeated COVID-19 infections pose not only to children but to society as a whole. We must act now to protect our future generations from these long-term consequences. We must work Together Against COVID Transmission.

These studies have significant bias. Females are much more likely to seek healthcare than males- same is true for the parents of the children. Healthcare is racist. The algorithms are racist. I have no doubt that there are many Black, Hispanic/Latino, Pacific Islander and Native American children with brain damage from omicron..but what pediatrician is going to even request an MRI for these children?
I worked in public health 2019-21. Black children were hospitalized for MIs-c at 5 times the rate of white children. I asked the epidemiologist team to
Do something to fix this disparity…I was told
To shut up and go
Away…
Nothing was ever done.
