Overview
COVID-19-associated encephalopathy must be differentiated from other causes of headache, seizure and loss of consciousness such as encephalitis, meningitis, stroke, tumor, brain hemorrhage, neurosyphilis, migraine, hypertensive encephalopathy, wernicke’s encephalopathy, abscess, drug toxicity, and seizure.

COVID-19-associated encephalopathy must be differentiated from other causes of headache, seizure and loss of consciousness such as encephalitis, meningitis, stroke, tumor, brain hemorrhage, neurosyphilis, migraine, hypertensive encephalopathy, wernicke’s encephalopathy, abscess, drug toxicity, and seizure.
