EEG Abnormalities in COVID-19 Patients: A Growing Concern
New research suggests that abnormalities in brain activity detected by Electroencephalography (EEG) tests are common among patients with neurological symptoms related to COVID-19. As the world grapples with the ongoing pandemic, understanding its impact on the brain becomes increasingly crucial.
The Impact of COVID-19 on the Brain
According to a review of research, around 15-25% of patients with severe COVID-19 may experience neurological symptoms, including headaches, confusion, seizures, and strokes. Doctors may refer patients experiencing such symptoms for an EEG test, which monitors the electrical activity of the brain by placing electrodes on the scalp.
Researchers from Baylor College of Medicine and the University of Pittsburgh analyzed EEG results from 617 patients reported in 84 different studies. The findings revealed several abnormalities, with the majority of these abnormalities occurring in the frontal lobes of the brain.
Interestingly, the researchers found that the severity of the disease, as well as the presence of preexisting neurological conditions, positively correlated with the extent of EEG abnormalities.
While the virus may not be directly responsible for all the damage, it's crucial to consider potential systemic effects of the infection, such as inflammation, low oxygen levels, and cardiac arrest, which may contribute to widespread EEG abnormalities.
The Persistent Challenge of Long COVID
Many individuals who have recovered from COVID-19 report ongoing health issues, commonly referred to as long COVID. Among these issues is "brain fog." A recent study suggests that COVID-19 might have a significant cognitive impact, potentially aging people by a decade.
As EEG abnormalities associated with the neurological symptoms of COVID-19 become more evident, concerns about the long-term consequences on the brain intensify. According to Dr. Zulfi Haneef, assistant professor of neurology/neurophysiology at Baylor, "There might be long-term issues that people need to be aware of."
On a positive note, approximately 56.8% of those who had follow-up EEG tests showed improvements. However, further research, including comprehensive neuroimaging studies, is needed to fully understand the impact of COVID-19 on the brain and the long-term neurological consequences.
Enlightening the Future
As the world continues to fight the coronavirus, understanding and addressing the neurological impacts of the disease become essential. Exploring treatments like transcutaneous auricular vagal nerve stimulation (taVNS) and conducting long-term follow-up studies may provide valuable insights into alleviating the symptoms of long COVID and minimizing long-term neurological effects.

- The research on EEG abnormalities in COVID-19 patients indicates a positive correlation between the severity of the disease and the extent of these abnormalities, which are often found in the frontal lobes of the brain, similar to those observed in patients with epilepsy seizures and other neurological disorders.
- As the ongoing pandemic continues to reveal long-term health implications, such as 'brain fog' and cognitive impairment, often referred to as long COVID, the focus on understanding the potential neurological consequences and developing targeted treatments like transcutaneous auricular vagal nerve stimulation (taVNS) becomes increasingly important for managing the symptoms of long COVID and minimizing long-term neurological effects.
- Healthcare professionals and scientists must continue to study various medical conditions, including COVID-19, to better understand the impact of the virus on the brain and overall health-and-wellness, especially in the context of preexisting neurological disorders and the potential systemic effects of the infection.
