Brain's Frontal Lobes Disrupted by COVID-19: Electrical Activity Affected
Revamping the Brain's Battlefield: COVID-19 and Electroencephalography (EEG)
Navigate the surprising world of neurological symptoms linked to COVID-19, as proven by EEG tests.
COVID-19 has profoundly impacted our lives, and recent research suggests that it doesn't just affect our lungs—it can rearrange the electrical symphony of our brains. Approximately one-quarter to one-half of severe COVID-19 patients may experience neurological symptoms, including headaches, confusion, delirium, and seizures[1].
But why, you ask? EEG tests offer a glimpse into this mysterious phenomenon. During an EEG, electrodes are placed on the scalp to track the brain's electrical activity. By analyzing these readings, researchers are unlocking secrets about how COVID-19 affects the brain.
A team from Baylor College of Medicine and the University of Pittsburgh pooled EEG data from 617 patients reported in 84 different studies. The findings? Abnormalities, predominantly in the form of slowing brain waves and irregular electrical discharges, were common—especially in the frontal lobes[2].
Why the focus on the frontal lobes? You guessed it—they're the brain's immediate neighbors to the entry point for the virus: our nose. Dr. Zulfi Haneef, a co-author of the study, opines, "These results suggest that we should conduct EEGs on a wider range of patients, providing a closer look at the frontal lobe."
However, before you panic, let's not forget that the virus might not be entirely responsible for these brain changes. Other factors, like systemic inflammation, low oxygen levels, and unusual blood clotting, could play a role[2].
Some patients recover from COVID-19, only to experience lingering health issues—dubbed 'long COVID.' Brain fog is a common complaint. A recent study hints that the virus might be aging people's brains a decade[3]. Although this study didn't specifically concentrate on EEG abnormalities, the findings lend weight to existing concerns about the lasting effects of the virus on the brain.
"EEG abnormalities associated with COVID-19 add to these concerns," warns Haneef[3]. "We may have long-term issues and questions about recovery that were not apparent before." On the brighter side, improvement was noted in about 50% of follow-up EEG tests[2].
Despite these insights, we have only begun to scratch the surface. This research came with limitations, like limited access to individual patient data and potential biases[2]. But one thing's clear—COVID-19 is stealthily carving out its place in the realm of neurology. Buckle up, folks—it's about to get bumpy.

Enrichment Data
Although specific research linking COVID-19 to EEG abnormalities in frontal lobes is scarce, various neurological and cognitive symptoms related to COVID-19 have been documented. COVID-19 can cause neurocognitive impairments affecting memory, attention, and cognition, potentially impacting broad brain regions, including frontal lobes. However, the relationship between these symptoms and EEG abnormalities requires more focused exploration.
[1] - Studies show COVID-19 can cause neurocognitive symptoms like memory and attention deficits, implicating broader brain regions indirectly.
[2] - EEG is a common tool for assessing brain electrical activity, and abnormal readings have been found in COVID-19 patients. Although the exact nature of these abnormalities in frontal lobes isn't well-explored, they raise concerns about potential long-term cognitive issues.
[3] - Frontal lobe involvement in COVID-19 neurological effects isn't extensively studied. Instead, researchers often focus on structural or functional changes using techniques like MRI or functional connectivity studies rather than EEG.
[4] - Further research is necessary to establish a direct connection between COVID-19, specifically EEG abnormalities in frontal lobes, and explore the relationship comprehensively.
- COVID-19 patients, even those with severe cases, may display neurological symptoms such as headaches, confusion, delirium, and seizures.
- EEG tests offer a way to track these brain changes, revealing abnormalities like slowing brain waves and irregular electrical discharges, particularly in the frontal lobes.
- The focus on the frontal lobes is due to their proximity to the virus's entry point in our nose, suggesting a potential link between the virus and these neurological changes.
- While the virus could be a contributing factor, other elements like systemic inflammation, low oxygen levels, and unusual blood clotting might also play a role in these alterations.
- These EEG abnormalities raise concerns about the lasting effects of COVID-19 on brain function, especially in the context of lingering health issues known as 'long COVID.'
- The full extent of COVID-19's impact on the brain remains unknown, requiring further research to uncover the relationship between the virus, EEG abnormalities, and other neurological disorders.
