Over half of COVID-19 patients showed normal electroencephalography (EEG) patterns. Neurological manifestations in SARS-CoV-2 infection were not specific and similar to other conditions.
Area of Science:
- Neurology
- Infectious Diseases
- Neurophysiology
Background:
- Neurological manifestations of SARS-CoV-2 infection are increasingly reported.
- Electroencephalography (EEG) is a key tool for assessing brain function.
Purpose of the Study:
- To systematically describe the electroencephalography (EEG) characteristics in patients with SARS-CoV-2 infection.
- To identify any specific EEG patterns associated with COVID-19.
Main Methods:
- Retrospective systematic study of 40 EEGs from 36 COVID-19 patients.
- Independent review by two neurologists using standardized terminology.
- Classification of EEG alterations into five categories.
Main Results:
- 57.5% of EEGs were normal to mildly altered.
- 42.5% showed moderate to critical EEG alterations.
- Generalized periodic discharges (GPDs) or rhythmic delta activity (RDA) were observed in 32.5%.
Conclusions:
- Over half of COVID-19 patients exhibited normal EEG findings.
- EEG alterations in COVID-19 were not specific and resembled patterns seen in other conditions.
