COVID-19's impact may interfere with the electrical activity in the frontal lobes of the brain.
Fresh Take:
It seems COVID-19 isn't just affecting our lungs; research suggests it's wreaking havoc on our brains as well. Here's the scoop:
Remember that time you felt sorta fuzzy after recovering from COVID-19? Scientists call it "brain fog," and it's just one of the many neurological symptoms some folks are experiencing. Around 15-25% of severe COVID-19 patients might deal with these issues, including headaches, confusion, and seizures.
When doctors suspect neurological problems, they often carry out an electroencephalography (EEG) test. This involves sticking some electrodes on your scalp to monitor your brain's electrical activity.
Researchers decided to dive into EEG data from 617 COVID-19 patients across 84 studies. Turns out, the frontal lobes of the brain were a hotspot for abnormal EEG results. As Dr. Zulfi Haneef, co-author of the study, points out, this region is in close proximity to the nose—COVID-19's entry point.
However, it's critical to note that the virus might not be solely responsible for the brain damage. Systemic effects of the infection, like inflammation, low oxygen levels, and unusual blood clotting, may also play a role in EEG abnormalities beyond the frontal lobes.
Another intriguing finding: "Diffuse slowing" in the background electrical activity of the entire brain was nearly present in 70% of patients.
But here's the good news: Most patients who had follow-up EEG tests showed improvements!
Now, there's a new twist—a study found that individuals reporting COVID-19 performed poorly on a cognitive test compared to those who didn't believe they had the virus. Experts suspect long-term cognitive decline might be a possible lasting effect of the infection. And the fact that COVID-19 can cause EEG abnormalities in the frontal lobes adds fuel to these concerns.
So, while the road to recovery might be a little bumpy, researchers are working tirelessly to understand the long-term effects of COVID-19 on our brains. Stay tuned!
Insight:- Although neurological sequelae of COVID-19 seem to be closely associated with frontal lobe issues as reflected in EEG, there's a need for more research to establish a direct correlation between COVID-19 and frontal lobe EEG abnormalities.
