Overview
Coronaviruses impacts are not always restricted to respiratory system and they have potential for neuroinvasion under specific circumstances. Neurological manifestations such as dizziness,headache ,anosmia as well as case reports with encephalitis ,stroke,epileptic seizures associated with covid-19, have been reported.
Historical Perspective
- A women with the past medical history of seizure following herpetic encephalitis ,presented with a sudden focal myoclonus and positive test for covid 19 in Italy, 23rd of april 2020.[1]
- Also, a cohort multicentre study was done in China, April 2020, demonstrating that COVID 19 doesn't increase the risk of symptomatic seizure in patients hospitalized with the acute respiratory phase of COVID 19.Although ,some seizure-like reactions are seen because of acute reaction to stress or hypocalcemia .[2]
Classification
There isn't any established classification for covid-19 associated seizure.
Pathophysiology
Although there are some evidences suggesting SARS-COV-2 may affect CNS through two direct ways:haematogenous and neuronal retrograde dissemination ,the exact neurotropic mechanisms of this virus are yet to be known.[3]
Causes
The aetiology of seizure regardless whether it is covid-19 or not ,is divided into two categories:
- 'Provoked seizures : these seizures usually have a temporary trigger such as CNS infection,electrolytes disturbance, withdrawal syndrome,sepsis ,fever, sleep deprivation and stroke.
- Unprovoked seizures: In this catrgory ,there isn't any obvious cause or precipitating factor .[4]
Differentiating COVID-19-associated seizure from other Diseases
Apart from the viral cause of the seizure, the differential diagnosis for this disease is usually based on the presenting symptoms as below:
- Generalized convulsive movements:Epilepsy-syncope with secondary jerking movement-Involuntary movement disorders and other neurological conditions
- Drop attack:Epilepsy-Cardiac-Brainstem abnormalities-vertebrobasilar ischemia-Idiopathic
- Transient focal motor and sensory attack :tics-tonic spasms of multiple
- Facial muscles and eye movement:partial seizures-movement disorder-Other neurological conditions.[5]
