Brain's Frontal Lobes Electrical Activity Disrupted by COVID-19
Every third patient who exhibits neurological symptoms with COVID-19 shows abnormalities in their frontal lobes, according to recent research. This intriguing correlation might suggest that the virus has a direct impact on this brain region. But what exactly are these abnormalities, and what do they mean for the people who experience them?
Here, we delve deeper into the findings and explore the potential mechanisms underlying these EEG anomalies.

A bulk of the research focuses on electromagnetic brain activity, specifically via electroencephalography (EEG) tests. These tests involve placing electrodes on the scalp to monitor the electrical activity of the brain. In analyzing EEG results from 617 patients, researchers found that prolonged brain waves and abnormal electrical discharges were the most common findings.
The severity of these abnormalities correlated strongly with the severity of the disease and whether the patients had preexisting neurological conditions. Interestingly, the virus may not be solely responsible for the damage, as systemic effects of the infection such as inflammation, low oxygen levels, and improper blood clotting may also play significant roles.
Now, let's take a look at the reasons behind these EEG abnormalities:
- Neuroinflammation: COVID-19 often provokes a systemic inflammatory response, which can cross the blood-brain barrier and induce neuroinflammation. This inflammation may affect neuronal activity and connectivity in the frontal cortex, ultimately manifesting as EEG abnormalities.
- Excitatory/Inhibitory Imbalance: Changes in the excitatory/inhibitory (E/I) ratio impact neural network excitability and synchronization. Abnormalities in this ratio can reflect altered cortical states that may occur post-infections, potentially impacting frontal brain regions.
- Neurotrophic Factors: Disruptions in brain-derived neurotrophic factor (BDNF) - a crucial molecule for neuronal survival and synaptic plasticity - have been linked to cognitive impairments and mood disorders. These changes may contribute to frontal lobe dysfunction and EEG abnormalities.
- Secondary Factors: Conditions such as fatigue, depression, and cognitive deficits related to ongoing immune dysregulation, vascular changes, and direct viral effects on neural tissue may exacerbate or be reflected by frontal lobe EEG abnormalities.
By understanding these mechanisms, we can better comprehend the implications of these EEG abnormalities and the potential long-term effects of COVID-19 on the brain. Moreover, this knowledge could guide researchers in developing targeted treatments and therapies to help those affected by these neurological complications.

- The study of these EEG abnormalities in COVID-19 patients emphasizes the importance of neurological conditions, especially those related to the frontal lobe, in the health-and-wellness sphere.
- Epilepsy seizures and other neurological disorders might be associated with these EEG anomalies as the virus's impact extends beyond the respiratory system, affecting mental-health and neurological areas such as the frontal cortex.
- CBD, a compound known for its therapeutic potential in managing neurological disorders, might offer support for individuals experiencing these EEG abnormalities due to its anti-inflammatory properties.
- Coronavirus's indirect effects, including systemic inflammation, low oxygen levels, and improper blood clotting, intertwine with direct viral effects on neural tissue, potentially exacerbating neurological conditions and EEG abnormalities.
