Acute stroke remains a medical emergency even during the COVID-19 pandemic. Most patients with COVID-19 infection present with constitutional and respiratory symptoms; while others present with atypical gastrointestinal, cardiovascular, or neurological manifestations. Here we present a series of four patients with COVID-19 that presented with acute stroke. Methods: We searched the hospital databases for patients that presented with acute stroke and concomitant features of suspected COVID-19 infection. All patients who had radiographic evidence of stroke and PCR-confirmed COVID-19 infection were included in the study. Patients admitted to the hospital with PCR-confirmed COVID-19 disease whose hospital course was complicated with acute stroke while inpatient were excluded from the study. Retrospective patient data were obtained from electronic medical records. Informed consent was obtained. Results: We identified four patients who presented with radiographic confirmation of acute stroke and PCRconfirmed SARS-CoV-2 infection. We elucidate the clinical characteristics, imaging findings, and the clinical course. Conclusions: Timely assessment and hyperacute treatment is the key to minimize mortality and morbidity of patients with acute stroke. Stroke teams should be wary of the fact that COVID-19 patients can present with cerebrovascular accidents and should dawn appropriate personal protective equipment in every suspected patient. Further studies are urgently needed to improve current understandings of neurological pathology in the setting of COVID-19 infection.
Neurodegeneration with brain iron accumulation (NBIA) is a group of genetic disorders characterized by abnormal iron deposition in the basal ganglia. We report that de novo mutations in WDR45, a gene located at Xp11.23 and encoding a beta-propeller scaffold protein with a putative role in autophagy, cause a distinctive NBIA phenotype. The clinical features include early-onset global developmental delay and further neurological deterioration (parkinsonism, dystonia, and dementia developing by early adulthood). Brain MRI revealed evidence of iron deposition in the substantia nigra and globus pallidus. Males and females are phenotypically similar, an observation that might be explained by somatic mosaicism in surviving males and germline or somatic mutations in females, as well as skewing of X chromosome inactivation. This clinically recognizable disorder is among the more common forms of NBIA, and we suggest that it be named accordingly as beta-propeller protein-associated neurodegeneration.
Neurodegenerative disorders with high iron in the basal ganglia encompass an expanding collection of single gene disorders collectively known as neurodegeneration with brain iron accumulation. These disorders can largely be distinguished from one another by their associated clinical and neuroimaging features. The aim of this study was to define the phenotype that is associated with mutations in WDR45, a new causative gene for neurodegeneration with brain iron accumulation located on the X chromosome. The study subjects consisted of WDR45 mutation-positive individuals identified after screening a large international cohort of patients with idiopathic neurodegeneration with brain iron accumulation. Their records were reviewed, including longitudinal clinical, laboratory and imaging data. Twenty-three mutation-positive subjects were identified (20 females). The natural history of their disease was remarkably uniform: global developmental delay in childhood and further regression in early adulthood with progressive dystonia, parkinsonism and dementia. Common early comorbidities included seizures, spasticity and disordered sleep. The symptoms of parkinsonism improved with l-DOPA; however, nearly all patients experienced early motor fluctuations that quickly progressed to disabling dyskinesias, warranting discontinuation of l-DOPA. Brain magnetic resonance imaging showed iron in the substantia nigra and globus pallidus, with a 'halo' of T1 hyperintense signal in the substantia nigra. All patients harboured de novo mutations in WDR45, encoding a beta-propeller protein postulated to play a role in autophagy. Beta-propeller protein-associated neurodegeneration, the only X-linked disorder of neurodegeneration with brain iron accumulation, is associated with de novo mutations in WDR45 and is recognizable by a unique combination of clinical, natural history and neuroimaging features.

Introduction The outbreak of coronavirus disease 2019 (COVID-19) has become one of the most serious pandemics of the recent times. Since this pandemic began, there have been numerous reports about the COVID-19 involvement of the nervous system. There have been reports of both direct and indirect involvement of the central and peripheral nervous system by the virus. Objective To review the neuropsychiatric manifestations along with corresponding pathophysiologic mechanisms of nervous system involvement by the COVID-19. Background Since the beginning of the disease in humans in the later part of 2019, the coronavirus disease 2019 (COVID-19) pandemic has rapidly spread across the world with over 2,719,000 reported cases in over 200 countries [World Health Organization. Coronavirus disease 2019 (COVID-19) situation report-96.,]. While patients typically present with fever, shortness of breath, sore throat, and cough, neurologic manifestations have been reported, as well. These include the ones with both direct and indirect involvement of the nervous system. The reported manifestations include anosmia, ageusia, central respiratory failure, stroke, acute inflammatory demyelinating polyneuropathy (AIDP), acute necrotizing hemorrhagic encephalopathy, toxic-metabolic encephalopathy, headache, myalgia, myelitis, ataxia, and various neuropsychiatric manifestations. These data were derived from the published clinical data in various journals and case reports. Conclusion The neurological manifestations of the COVID-19 are varied and the data about this continue to evolve as the pandemic continues to progress.
To study the risk of acquiring Corona Virus Disease 2019 (COVID-19) and its outcomes in patients on immunosuppressive therapy (IST) for chronic autoimmune neuromuscular disorders (aNMD) and multiple sclerosis (MS). Methods: We used TriNetX, a global health collaborative clinical research platform collecting real-time electronic medical records data, which has one of the largest known global COVID-19 database. We included patients with chronic autoimmune neuromuscular disorders (aNMD) [myasthenia gravis (MG), inflammatory myositis, and chronic inflammatory neuropathies (CIN)] and MS, based on the International Classification of Disease-10 (ICD-10) coding for one year before January 20th, 2020. We examined the use of IST, rate of COVID-19, hospitalization, intubation, and mortality among the patients with aNMD and MS. Results: A total of 33,451 patients with aNMD and 42,899 patients with MS were included. Among them, 111 (0.33%) patients with aNMD and 115 patients (0.27%) with MS had COVID-19. About one third of them required hospitalization. IST did not appear to have a significant impact on overall infection risk in either group; however, risk of hospitalization for immunosuppressed patients with aNMD was higher (Odds ratio 2.86, p-value 0.011). Conclusions: IST use does not appear to make patients with aNMD and MS more vulnerable to COVID-19. IST may be continued during the pandemic, as previously suggested by expert opinion guidelines. However, it is important to consider individualizing immunotherapy regimens in some cases. Additional physician reported registry-based data is needed to further confirm these findings.
