- W4377011056 abstract "During corona virus pandemic, various neurological complications of COVID-19 have been reported. Recent studies demonstrated different pathophysiology for neurological manifestations of COVID-19 such as mitochondrial dysfunction and damage to cerebral vasculature. In addition, mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is a mitochondrial disorder with a variety of neurological symptoms. In this study, we aim to assess a potential predisposition in mitochondrial dysfunction of COVID-19, leading to MELAS presentation.We studied three previously healthy patients with the first presentation of acute stroke-like symptoms, following COVID-19 infection. We analyzed the patients' clinical data and brain magnetic resonance imaging (MRI) lesions that presented to the neurological center of a university-affiliated hospital in Tehran, Iran, from September 2020 to August 2021.All cases are characterized by a temporoparietal abnormality in imaging studies and electroencephalogram (EEG). Based on electrodiagnostic tests, three patients were diagnosed with myopathy. In two brothers with relatively the same symptoms, one performed muscle biopsy finding myopathic process, and genetic testing confirmed a 3243A>G point mutation in a heteroplasmic state in one of our patients.Although MELAS is not a prevalent condition, the recent increase in the number of these patients in our center might indicate the potential role of COVID-19 in triggering the silent pre- existing mitochondrial dysfunction in these patients." @default.
