Hypersomnia secondary to severe acute respiratory syndrome coronavirus-2 infection: Natalia Bravo Quelle; Ann Clin Neurophysiol 2024;26(2):63-66. Published online September 26, 2024; DOI: https://doi.org/10.14253/acn.24004

Excessive daytime sleepiness (EDS), with or without an excessive need for sleep, is a primary reason for patients seeking consultation at the sleep unit. EDS is observed in ~5% of the general population. Common causes of EDS include obstructive sleep apnea, sleep deprivation, effects of medication, psychiatric disease (especially depression), and circadian rhythm disorders. Coronavirus disease 2019 (COVID-19) infection is a rare cause of EDS. We present a case of mild COVID-19 infection as an unusual cause of hypersomnolence.

Post-infectious basal ganglia encephalitis and axonal variant of Guillain-Barré syndrome after COVID-19 infection: an atypical case report: Jiwon Yang, Dong-Jin Shin, Hyeon-Mi Park, Yeong-Bae Lee, Young-Hee Sung; Ann Clin Neurophysiol 2022;24(2):101-106. Published online October 31, 2022; DOI: https://doi.org/10.14253/acn.2022.24.2.101; Correction in: Ann Clin Neurophysiol 2023;25(1):54

Neurological complications attributed to coronavirus disease-19 (COVID-19) infection have been reported including acute disseminated encephalomyelitis, Guillain-Barré syndrome, and so on. Herein, we report a 49-year-old woman presented with acute encephalopathy and paraplegia simultaneously after COVID-19 infection. Brain magnetic resonance imaging (MRI) showed symmetric hyperintense basal ganglia lesions on T2-weighted imaging. Cerebrospinal fluid pleocytosis, motor axonal neuropathy and enhancement of conus medullaris nerve roots on spine MRI were observed. We treated her with high-dose corticosteroid and intravenous immunoglobulin.

A Case of Glycogen Storage Disease Type V with Rhabdomyolysis after COVID-19 Vaccination: Hokyu Kim, Ye-eun Kim, Hye Lim Lee; Korean J Neuromuscul Disord 2021;13(2):55-58. Published online December 31, 2021; DOI: https://doi.org/10.46518/kjnmd.2021.13.2.55

Glycogen storage disease (GSD) type V, also known as McArdle’s disease, is an autosomal recessive genetic disease caused by a mutation of the PYGM gene related to the synthesis of the myophosphorylase enzyme. Here, we presented the case of an 83-year-old woman who was admitted for progressively worsening weakness of her legs due to rhabdomyolysis after a COVID-19 vaccination. In the muscle biopsy, myopathy with subsarcolemmal glycogen accumulation was revealed and she was diagnosed with a mild form of GSD type V. Although COVID-19 vaccines are generally safe and encouraged for everyone, adverse events following COVID-19 vaccinations are increasing. We should pay attention to the side effects of COVID-19 vaccination including rhabdomyolysis.
