Dear Editor: Coronavirus disease-2019 (COVID-19) has devastated healthcare systems and public health globally. Many patients develop a wide spectrum of persisting or new symptoms 3 months after the acute COVID-19 illness (long-COVID-19), and these symptoms can persist for at least 2 months. There is significant variability in the definitions with the lack of standardization and hence the reported frequency of long-COVID-19 also varies. Furthermore, there is sparser data with a significant heterogeneity on neurological long-COVID-19 symptoms.
