Viral diseases of the nervous system-Selected new and old viruses
Nervenarzt. 2023 Mar 21. doi: 10.1007/s00115-023-01452-0. Online ahead of print.ABSTRACTViral diseases of the nervous system are ancient and poliomyelitis was described in Egypt as early as 2000 BC. They can cause a wide range of neurological symptoms, such as meningitis, encephalitis, meningoencephalitis, Guillain-Barré-like syndrome and stroke, often leaving mild to severe residuals. Depending on the pathogen, the symptoms appear quickly within hours, or lead to increasing chronic symptoms within 1 week or months. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which was newly identified in January 202...

Patterns of acute ischemic stroke and intracranial hemorrhage in patients with COVID-19
In this study, we sought to investigate associations between neuroimaging findings with clinical, demographic, blood and cerebrospinal fluid (CSF) parameters, pre-existing conditions and the severity of acute COVID-19.Materials and methodsRetrospective multicenter data retrieval from 10 university medical centers in Germany, Switzerland and Austria between February 2020 and September 2021. We included patients with COVID-19, acute neurological symptoms and cranial imaging. We collected demographics, neurological symptoms, COVID-19 severity, results of cranial imaging, blood and CSF parameters during the hospital stay.Resul...

Neurovascular manifestations of COVID ‑19
Nervenarzt. 2021 Mar 24. doi: 10.1007/s00115-021-01104-1. Online ahead of print.ABSTRACTEven early at the beginning of the coronavirus disease 2019 (COVID‑19) pandemic, stroke was described as a manifestation or complication of infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Current meta-analyses reported a stroke rate of approximately 1.5%. Stroke in COVID‑19 positive patients occurs more frequently in severe courses of the infection and in older patients with cardiovascular comorbidities; however, young patients without cardiovascular risk factors are also not uncommonly affected. The me...

Coronavirus disease-19 (COVID-19) related acute stroke causing Transient Global Amnesia
Transient global amnesia (TGA) presents as an acute anterograde amnesia that generally resolves within 24 hrs.1 Werner et al. had noted increasing TGA since severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak in their hospital in Germany and reported 16 patients with TGA between February 1st and May 15th 2020 compared to their 10-year average of 9.72 In our series we noted 2 patients who presented with TGA secondary to acute hippocampal stroke in COVID-19 positive patients.

Stroke Admissions, Stroke Severity, and Treatment Rates in Urban and Rural Areas During the COVID-19 Pandemic
Conclusions: During the early pandemic, deviations of stroke-related admissions from historical averages were observed in both urban and rural regions of Northeastern Germany and appear to have been mainly driven by avoidance of admissions of mildly affected stroke patients.

Stroke Care Within the COVID-19 Pandemic —Increasing Awareness of Transient and Mild Stroke Symptoms Needed
Conclusions: During the COVID-19 pandemic, resources of the healthcare system in a primary care university hospital in Germany still allowed for unchanged numbers of recanalization procedures due to ischemic stroke. However, the numbers of patients admitted to the hospital specifically due to ischemic stroke or TIA decreased, suggesting that the awareness for non-disabling stroke symptoms has to be increased.
