Abstract
Background and Objectives
Although immunization against coronavirus disease 2019 (COVID-19) is ongoing, adverse reactions to these vaccinations have been observed in isolated cases. We aimed to report different neurological complications developed after COVID-19 vaccination.
Materials and Methods
In our case series study, we report all cases of CNS demyelination following COVID-19 immunization. Clinical evaluation, brain MRI, and CSF analysis for oligoclonal bands and IgG index were performed for all patients. Other investigations were performed for selected patients, including spine MRI, EEG, VEP, and aquaporin-4.
Results
Eighteen patients (eight males and ten females) with no history of COVID-19 infection had neurological manifestations (vertigo, ataxia, recurrent attacks of loss of consciousness, optic neuritis, and myelitis) starting within 14 days after Pfizer (n = 12) and AstraZeneca (n = 6) vaccination. MRI was obtained during the acute stage of the disease. The most common presenting symptoms were optic neuritis and hemiparesis. Sixteen patients had altered signal intensity and multiple variable-sized, round to ill-defined oval lesions suggestive of MS. Two showed findings compatible with transverse myelitis.
Conclusion
This study identified CNS demyelination complications after COVID-19 vaccination. The COVID-19 vaccination could result in CNS complications, possibly connected to a post-vaccination inflammatory process. We recommend continuous post-marketing monitoring for adverse reactions in individuals who received the vaccines to establish a connection and guarantee the long-term safety of COVID-19 vaccines.
