Analysis Shows Nearly a Third of COVID-19 Patients Have Brain Abnormalities
An analysis of more than 80 studies reporting complications experienced by COVID-19 patients has revealed that about one-third of them have abnormalities in the frontal lobe of the brain, findings which shed light on the neurological symptoms of the disease.
The review of studies, published in Seizure: European Journal of Epilepsy, focused on abnormalities detected using electroencephalogram (EEG) scans, which are used to evaluate the electrical activity in the brain.
“We found more than 600 patients were affected in this way. Before now, when we saw this in small groups we weren’t sure if this was just a coincidence, but now we can confidently say there is a connection,” said Zulfi Haneef, an assistant professor of neurology at Baylor College of Medicine in the US.
To study the clinical value of electroencephalogram (EEG) in the diagnosis of epilepsy.
Changmin Ke, Peiping Wang and Chuna Zheng made an analysis on the clinical value of electroencephalogram in diagnosis of epilepsy, and in this research, 80 patients with epilepsy in the Fifth Affiliated Hospital of Sun Yat-sen University from January to December 2019 were taken as research objects. EEG was applied to diagnose and analyze the electrical activity of these patients, results of which were compared with those of clinical diagnosis.
According to the statistics, the number of patients with epilepsy diagnosed by clinical manifestations and EEG was 78 and 75 respectively. The accuracy of EEG was calculated to be 96.2%. There was no significant difference between the diagnostic results of these two methods, and the results didn’t reach statistical significance (p > 0.05).
The conclusion that EEG has high accuracy in detecting and diagnosing epilepsy in clinic is worth promoting.
