COVID-19, de novo seizures, and epilepsy: a systematic review.

ABSTRACT

OBJECTIVE: We discuss the evidence on the occurrence of de novo seizures in patients with COVID-19, the consequences of this catastrophic disease in people with epilepsy (PWE), and the electroencephalographic (EEG) findings in patients with COVID-19. METHODS: This systematic review was prepared according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. MEDLINE, Scopus, and Embase from inception to August 15, 2020 were systematically searched. These key words were used "COVID" AND "seizure" OR "epilepsy" OR "EEG" OR "status epilepticus" OR "electroencephalography". RESULTS: We could identify 62 related manuscripts. Many studies were case reports or case series of patients with COVID-19 and seizures. PWE showed more psychological distress than healthy controls. Many cases with new-onset focal seizures, serial seizures, and status epilepticus have been reported in the literature. EEG studies have been significantly ignored and underused globally. CONCLUSION: Many PWE perceived significant disruption in the quality of care to them, and some people reported increase in their seizure frequency since the onset of the pandemic. Telemedicine is a helpful technology that may improve access to the needed care for PWE in these difficult times. De novo seizures may occur in people with COVID-19 and they may happen in a variety of forms. In addition to prolonged EEG monitoring, performing a through metabolic investigation, electrocardiogram, brain imaging, and a careful review of all medications are necessary steps. The susceptibility of PWE to contracting COVID-19 should be investigated further.
