Brain's Frontal Lobes Can Experience Electrical Disruptions Due to COVID-19
The research unveils a connection between the neurological symptoms of COVID-19 patients and abnormalities in their brains, particularly in the frontal lobes, as revealed by EEG tests.
Approximately 15-25% of severe COVID-19 cases might experience neurological issues like headaches, confusion, seizures, and strokes. Medical professionals may order an EEG test, involving electrodes placed on the scalp to monitor brain electrical activity, for patients experiencing such symptoms.
Researchers from Baylor College of Medicine and the University of Pittsburgh analyzed EEG results from 617 patients across 84 studies. They discovered that one-third of the abnormalities were located in the frontal lobes, noted Dr. Zulfi Haneef, one of the study's co-authors. This coincides with the usual entry point of the virus, which is the nose, hinting at a possible association.
These EEG abnormalities tend to escalate with the severity of the disease and the presence of pre-existing neurological conditions. The researchers suggest that the virus may not be solely responsible for all damage; systemic effects of the infection might also contribute to EEG abnormalities that extend beyond the frontal lobes.
The study highlighted "diffuse slowing" in the background electrical activity of the whole brain in nearly 70% of patients. Some individuals who have recovered from COVID-19 claim long-lasting health issues, such as "brain fog." A recent, unpublished study on MedRxiv suggested that the virus might accelerate cognitive aging by around a decade for those who report having COVID-19. While this study doesn't necessarily prove long-term cognitive decline, it certainly raises concerns about the long-term effects of the virus on the brain.
Dr. Haneef echoes these concerns, stating that while improvements have been observed in some patients upon follow-up EEG tests, there might be long-term complications, which could explain the cognitive issues some individuals continue to experience post-recovery.
In conclusion, while further research is required to establish a definitive relationship between COVID-19 and frontal lobe abnormalities as detected by EEG tests, the findings suggest that the virus might have long-lasting effects on cognitive function. It's crucial to remain vigilant and follow COVID-19 guidelines to minimize risks and potential neurological complications.
Note: Currently, there is limited direct information available on the correlation between COVID-19 and abnormalities in the frontal lobes of the brain as detected by EEG tests. However, COVID-19 can lead to neurocognitive impairments, including memory and attention deficits. These symptoms are typically linked to brain regions including the frontal lobes, which are crucial for cognitive functions. EEG is used to assess electrical activity in the brain, and while specific studies linking COVID-19 with frontal lobe EEG abnormalities are not mentioned, EEG can detect abnormalities in brain activity, which could be relevant in assessing neurocognitive symptoms associated with COVID-19.
