Brain's Frontal Lobes Electrical Activity Potentially Affected by COVID-19
Exploring Brain Abnormalities Linked to COVID-19
Research suggests that an alarmingly high number of COVID-19 patients present neurological symptoms, with around 15-25% of severe cases experiencing issues such as headaches, confusion, seizures, and strokes. To better understand these symptoms and their correlation with the virus, scientists have been analyzing Electroencephalography (EEG) test results from patients across various studies.
EEG Insights
EEG tests monitor the brain's electrical activity by placing electrodes on the scalp. Recent investigations into COVID-19's impact on the brain revealed that abnormalities in EEG results, particularly in the frontal lobes, are quite common among infected patients.
Dr. Zulfi Haneef, an assistant professor of neurology/neurophysiology at Baylor College of Medicine, noted that the frontal lobes, located close to the virus's likely entry point – the nose – may be prone to damage due to the infection. He urged further research utilizing EEG tests, as well as other brain imaging techniques like MRI or CT scans, to better understand and visualize the frontal lobe's condition.
Systemic Effects
The researchers acknowledged that the virus might not be responsible for all EEG abnormalities, as systemic effects of the infection, such as inflammation, low oxygen levels, and cardiac arrest, could also contribute to these issues. The study revealed "diffuse slowing" in the background electrical activity of the brain in nearly 70% of patients, suggesting that the virus may indeed affect various regions of the brain.
Brain Fog and Long COVID
Recovered COVID-19 patients have reported experiencing ongoing health problems, which has been collectively dubbed "long COVID." One common concern is "brain fog," a cognitive decline that can linger for weeks or even months after recovery. A recent study, though yet to be peer-reviewed, demonstrated that individuals with a history of COVID-19 performed less well on an online cognitive test than those who did not believe they contracted the virus.
The study's findings emphasize concerns about long-term cognitive decline as a result of the virus, further highlighting the need for more research to accurately assess long COVID's impact on the brain. Dr. Haneef supports this perspective, noting that the EEG abnormalities associated with COVID-19 neurological symptoms only serve to increase such concerns.
Recovery and Future Research
The Baylor College of Medicine study offers a glimmer of hope, as findings revealed that approximately 56.8% of followed-up patients showed improvements in their EEG results. Despite the study's limitations, such as the lack of raw data and potential skewing of results due to the focus on patients with neurological symptoms, it paves the way for further research into the neurological impact of COVID-19 and the development of effective rehabilitation strategies.

- While COVID-19 primarily attacks the respiratory system, research also suggests a link between it and various neurological conditions, such as epilepsy seizures and strokes.
- Acknowledging the need for research, scientists are analyzing Electroencephalography (EEG) test results to understand the correlation between the virus and neurological symptoms, focusing on abnormalities in the frontal lobes.
- The potential for the coronavirus to wreak havoc on digestive health, eye health, hearing, cardiovascular health, mental health, and skin conditions remains largely unexplored due to the current focus on its neurological impact.
- The effects of the virus extend beyond the brain, with systemic issues like inflammation, low oxygen levels, and cardiac arrest possibly contributing to the observed EEG abnormalities.
- It is crucial to assess the long-term health effects of COVID-19, as patients have reported experiencing cognitive decline, or "brain fog," for weeks or even months after recovery.
- Recent studies have suggested that medical conditions like cancer, respiratory conditions, and autoimmune disorders may increase the risk of severe COVID-19 complications, but the specific link between these conditions and neurological abnormalities remains unclear.
- The environmental science community is also closely watching the potential impact of climate change on COVID-19, as changes in temperature and humidity could influence the virus's survival and transmission rates.
- To support overall health and wellness, it is vital to prioritize fitness and exercise, including proper diet, sleep, and stress management techniques, especially during the pandemic when many are confined to their homes.
- Pharmaceutical research efforts include investigating the potential of Compound CBD as a possible treatment for COVID-19 neurological complications, as it has shown promise in managing various neurological disorders.
- Beyond COVID-19, understanding the long-term impact of systemic inflammation on neurological disorders like multiple sclerosis and Alzheimer's disease should remain a focus for the medical community to improve treatment strategies and develop preventative measures.
