Evaluating the Impact of the COVID-19 Pandemic on Acute Ischemic Stroke Outcomes in the Stroke Belt

Objectives: The COVID-19 pandemic disrupted many facets of healthcare including patients delaying medical care for potentially life-threatening conditions. This study sought to compare specific key outcomes related to ischemic stroke that occurred before and during the COVID-19 pandemic. We assessed mortality rates, morbidity rates, and the administration of thrombolytics in patients with ischemic stroke admitted to emergency departments (ED) in the Stroke Belt, a region of the United States with historically worse stroke outcomes. Method(s): Cerner Real-World Data was used to identify patients residing in the Stroke Belt (Southeastern United States) who were admitted to the ED with ICD-10 codes indicating acute ischemic stroke. We determined in-hospital and 30-day mortality rates, morbidity rates (physical disability tracked 1-year post-ischemic stroke), and administration of thrombolytics for acute ischemic stroke patients before the COVID-19 pandemic (March 2019-February 2020) and during the pandemic (March 2020-February 2021). Result(s): In the defined period prior to COVID-19, 2,338 patients presented to the ED with ischemic strokes (49.5% male;mean age 64.8, SD:15.23;69.6% white). During COVID-19, 2,052 ischemic stroke patients presented to the ED (50.9% male;mean age 65.8, SD:15.04;71.5% white). Our analyses show a significant decrease in thrombolytic administration during the pandemic compared to before the pandemic (12.2% and 14.5%, respectively;p<0.05). There was no significant difference in rates of in-hospital mortality, 30-day mortality, or morbidity following ischemic strokes. Conclusion(s): The findings of our study suggest a reduction in ischemic stroke related ED encounters during the COVID-19 period, but no differences were observed in mortality and morbidity rates in ischemic stroke compared to before the pandemic. Future studies are required to determine if these trends were true in other regions of the United States, as well as to investigate other potential covariates linked to outcomes before and during the COVID-19 pandemic.Copyright © 2023

Rate of Recombinant Tissue Plasminogen Activator (rtPA) Administration for Acute Ischemic Stroke Treatment during the COVID-19 Pandemic in Thailand

Background: Coronavirus disease 2019 (COVID-19] has become a global pandemic. Preventive policy during this outbreak possibly leads to a negative influence on the highly time-sensitive diseases such as acute ischemic stroke (AIS]. Objective(s): The present study was to determine the impact of the pandemic on rate of recombinant tissue plasminogen activator (rtPA] administration for AIS in Thailand. Material(s) and Method(s): A cross-sectional descriptive study. The magnitude of COVID-19 pandemic in each province of Thailand was reviewed from the website of the Ministry of Public Health. The number of patients with AIS who received rtPA was taken from the National Health Security Office, from 1st October 2019 to 21st August 2021. The authors demonstrate the correlation between the pandemic severity and the rate of rtPA administration for patients with AIS. Result(s): During the COVID-19 pandemic, there were 37 provinces (48%] in year 2020 and SO provinces (64.9%] in year 2021 had a reduction in rate of rtPA administration, 40 provinces (51.9%] in year 2020 and 27 provinces (35%] in year 2021 had increase in rate of rtPA administration. Over a period of two years, 25 provinces (32.5%] had only decreased rate (mean=1.12% and 1.63% in year 2020 and 2021 respectively], 15 provinces (19.5%) had only increased rate (mean=1.71% and 1.17% in year 2020 and 2021 respectively], and 37 provinces (48%] had diverse in rate of rtPA administration among both years. Conclusion(s): The present study demonstrated that the COVID-19 pandemic does not cause a significant impact on the rate of rtPA administration for AIS in Thailand.Copyright © 2023 Journal of the Medical Association of Thailand.

Intravenous Thrombolysis for Acute Ischemic Stroke during COVID-19 Pandemic in Srinagarind Hospital

Background: Stroke is the leading cause of death and disability worldwide. In COVID-19 pandemic, stroke remains to be a medical emergency. To treat patients with acute ischemic stroke [AIS], early intravenous thrombolysis is highly time sensitive. This research investigated the impact of regionally imposed social and healthcare restrictions of COVID-19 on the time metrics in the management of AIS patients admitted at the stroke unit center in Srinagarind Hospital. Objective(s): Comparison of door to needle time for intravenous thrombolysis for AIS patients before and after the COVID-19 outbreak. Material(s) and Method(s): The present study is a retrospective analysis of patients with AIS who received intravenous tissue plasminogen activator [tPA] from 1 January 2019 to 31 December 2020 in Srinagarind Hospital, Khon Kaen. The patients admitted before and after the COVID-19 outbreak [January 13, 2020, as officially announced by the World Health Organization] were screened to collect sociodemographic data, medical history information, and symptom onset status from clinical medical records and to compared door-to-needle time (DNT) for intravenous thrombolysis before and after the outbreak. Result(s): A total of 239 patients were included, of which 113 were enrolled before and 126 after the COVID-19 outbreak. According to the findings, DNT is 35.3 minutes before the pandemic and 35.8 minutes after the epidemic. Conclusion(s): COVID-19 has remarkable impacts on the management of AIS. However, DNT for before and after COVID-19 outbreak is nearly identical. It was established that administering intravenous thrombolysis to patients in the emergency room rather than the stroke unit allowed for speedier access. Therefore, a policy which provides quick AIS treatments in COVID-19 situations should be implemented.Copyright © 2023 Journal of the Medical Association of Thailand.

Post-COVID-19 Multisystem Inflammatory Syndrome-Related Cerebral Infarction in a Pediatric Patient Managed with Decompressive Craniectomy.

INTRODUCTION: Most people who are infected with the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) are asymptomatic or present with mild upper respiratory symptoms. This is especially true in the pediatric population; however, rarely, a massive cytokine storm can develop, causing multisystem inflammatory syndrome associated with COVID (MIS-C). Furthermore, children may also suffer from acute ischemic strokes secondary to SARS-CoV-2 infection. CASE PRESENTATION: Here, we present a 2-year-old male who was admitted to the hospital with MIS-C and evidence of a previous SARS-CoV-2 infection. On postadmission day 2, the patient was in cardiogenic shock, had acute kidney injury, liver dysfunction, and metabolic acidosis. He had concurrent altered mental status, and his computed tomography scan showed ischemic infarcts in the territory of the right middle cerebral artery and superior cerebellar artery bilaterally. Magnetic resonance angiography confirmed occlusion of the right middle cerebral artery and right superior cerebellar artery. He underwent an emergent decompressive craniectomy due to rapid deterioration and cerebral edema. After the procedure, he continued to improve and was discharged with moderate disability that improved during outpatient rehab. CONCLUSION: Though rare in children, SARS-CoV-2 can lead to AIS, especially in the presence of underlying risk factors such as MIS-C and hypercoagulopathy. AIS can be associated with severe mortality and morbidity; however, even in this severe case of AIS, the patient was successfully treated with a decompressive craniectomy.

Developing DELPHI expert consensus rules for a digital twin model of acute stroke care in the neuro critical care unit.

INTRODUCTION: Digital twins, a form of artificial intelligence, are virtual representations of the physical world. In the past 20 years, digital twins have been utilized to track wind turbines' operations, monitor spacecraft's status, and even create a model of the Earth for climate research. While digital twins hold much promise for the neurocritical care unit, the question remains on how to best establish the rules that govern these models. This model will expand on our group's existing digital twin model for the treatment of sepsis. METHODS: The authors of this project collaborated to create a Direct Acyclic Graph (DAG) and an initial series of 20 DELPHI statements, each with six accompanying sub-statements that captured the pathophysiology surrounding the management of acute ischemic strokes in the practice of Neurocritical Care (NCC). Agreement from a panel of 18 experts in the field of NCC was collected through a 7-point Likert scale with consensus defined a-priori by ≥ 80% selection of a 6 ("agree") or 7 ("strongly agree"). The endpoint of the study was defined as the completion of three separate rounds of DELPHI consensus. DELPHI statements that had met consensus would not be included in subsequent rounds of DELPHI consensus. The authors refined DELPHI statements that did not reach consensus with the guidance of de-identified expert comments for subsequent rounds of DELPHI. All DELPHI statements that reached consensus by the end of three rounds of DELPHI consensus would go on to be used to inform the construction of the digital twin model. RESULTS: After the completion of three rounds of DELPHI, 93 (77.5%) statements reached consensus, 11 (9.2%) statements were excluded, and 16 (13.3%) statements did not reach a consensus of the original 120 DELPHI statements. CONCLUSION: This descriptive study demonstrates the use of the DELPHI process to generate consensus among experts and establish a set of rules for the development of a digital twin model for use in the neurologic ICU. Compared to associative models of AI, which develop rules based on finding associations in datasets, digital twin AI created by the DELPHI process are easily interpretable models based on a current understanding of underlying physiology.

A rare case of central post-stroke pain in a patient with migraine and lacunar infarcts in the medulla oblongata

Studies about headaches associated with acute ischemic stroke in patients suffering from migraine were limited, and therefore we present a clinical case of central post-stroke pain (CPSP) in a 47-year-old woman with migraine and lacunar infarcts in the medulla oblongata and also possible mechanisms of CPSP in patients with migraine. Magnetic resonance imaging of the brain revealed lacunar infarction in the medulla oblongata on the right (vertebral artery basin) and a single focus of gliosis in the parietal lobe on the right. Magnetic resonance angiography of cerebral vessels showed the fetal type of structure of both posterior cerebral arteries. This clinical case is a complex clinical situation of a combination of secondary headaches (post-stroke) in a patient with a primary headache (migraine), which was successfully treated by the combined administration of first-line drugs for the treatment of neuropathic pain in a patient with lacunar infarcts in the medulla oblongata. The treatment of CPSP is a difficult task due to the insufficiently unexplored mechanisms of development, the most effective approaches are those aimed at reducing the increased excitability of neurons.Copyright © 2023, Indian Association of Biomedical Scientists.

Comparison of acute ischemic stroke care quality before and during the COVID-19 pandemic in a private tertiary hospital in metro Manila, Philippines

Background: The Coronavirus Disease 2019 (COVID-19) pandemic had disrupted established medical care systems worldwide, especially for highly time-sensitive acute conditions such as stroke. Strategies to maintain the quality of stroke care during the COVID-19 outbreak are crucial to prevent indirect mortality and disability due to suboptimal care. Objective: We conducted a single center analysis to compare the time-based measures for acute ischemic stroke care quality before and during the COVID-19 pandemic. Methods: A retrospective study was done utilizing the Registry of Stroke Care Quality (RES-Q) database. All acute ischemic stroke patients who presented within 4.5 hours of symptom onset in Makati Medical Center were included. Patient characteristics, treatment received, in-hospital time-based measures of stroke care quality and clinical outcomes were compared between the two periods-pre-COVID-19 and COVID-19. Results: There were 151 patients during the pre-COVID-19 period and 108 patients during the COVID-19 period who presented to the hospital with acute ischemic strokes within 4.5 hours of symptom onset. There was significantly higher NIHSS scores on admission and MRS scores on discharge during the COVID-19 period. There was no significant difference in the door-to-scan time, door-to-needle time and door-to-groin time between the two periods. Conclusion: There is no significant change in the acute ischemic stroke care quality on the basis of in-hospital time-based measures: door-to-scan time, door-to-needle time, and door-to-groin time, between the pre-COVID-19 and COVID-19 periods. Further studies on pre-hospital challenges are recommended to identify specific targets for improvements in stroke care during pandemics. © 2023, ASEAN Neurological Association. All rights reserved.

Mechanical thrombectomy for acute multivessel occlusions with duplicated middle cerebral artery: A case report.

Acute multivessel occlusions generally have multisite clot burden with lower successful reperfusion rates, and cerebrovascular anatomical variants increase the challenge of endovascular clot retrieval. We report a case of acute anterior multivessel occlusions patient with duplicated middle cerebral artery. Combined balloon guide catheter with stent retriever and aspiration approach has gained complete revascularization and good functional outcomes at 3 months follow-up.

Pathophysiology of Cardiac Injury in COVID-19 Patients with Acute Ischaemic Stroke: What Do We Know So Far?-A Review of the Current Literature.

With the onset of the COVID-19 pandemic, it became apparent that, in addition to pulmonary infection, extrapulmonary manifestations such as cardiac injury and acute cerebrovascular events are frequent in patients infected with SARS-CoV-2, worsening clinical outcome. We reviewed the current literature on the pathophysiology of cardiac injury and its association with acute ischaemic stroke. Several hypotheses on heart and brain axis pathology in the context of stroke related to COVID-19 were identified. Taken together, a combination of disease-related coagulopathy and systemic inflammation might cause endothelial damage and microvascular thrombosis, which in turn leads to structural myocardial damage. Cardiac complications of this damage such as tachyarrhythmia, myocardial infarction or cardiomyopathy, together with changes in hemodynamics and the coagulation system, may play a causal role in the increased stroke risk observed in COVID-19 patients. These hypotheses are supported by a growing body of evidence, but further research is necessary to fully understand the underlying pathophysiology and allow for the design of cardioprotective and neuroprotective strategies in this at risk population.

Admission chest CT findings and risk assessment for stroke-associated pneumonia.

INTRODUCTION: Stroke-associated pneumonia (SAP) is a significant cause of morbidity and mortality after stroke. Various factors, including dysphagia and stroke severity, are closely related to SAP risk; however, the contribution of the baseline pulmonary parenchymal status to this interplay is an understudied field. Herein, we evaluated the prognostic performance of admission chest computed tomography (CT) findings in predicting SAP. METHODS: We evaluated admission chest CT images, acquired as part of a COVID-19-related institutional policy, in a consecutive series of acute ischemic stroke patients. The pulmonary opacity load at baseline was quantified using automated volumetry and visual scoring algorithms. The relationship between pulmonary opacities with risk of pneumonia within 7 days of symptom onset (i.e., SAP) was evaluated by bivariate and multivariate analyses. RESULTS: Twenty-three percent of patients in our cohort (n = 100) were diagnosed with SAP. Patients with SAP were more likely to have atrial fibrillation, COPD, severe neurological deficits, and dysphagia. The visual opacity score on chest CT was significantly higher among patients who developed SAP (p = 0.014), while no such relationship was observed in terms of absolute or relative opacity volume. In multivariate analyses, admission stroke severity, presence of dysphagia and a visual opacity score of ≥ 3 (OR 6.37, 95% CI 1.61-25.16; p = 0.008) remained significantly associated with SAP risk. CONCLUSIONS: Pulmonary opacity burden, as evaluated on admission chest CT, is significantly associated with development of pneumonia within initial days of stroke. This association is independent of other well-known predisposing factors for SAP, including age, stroke severity, and presence of dysphagia.

OPTIMAS: A randomised controlled trial to establish the optimal timing of anticoagulation after acute ischaemic Stroke

Introduction: Atrial fibrillation (AF) causes about one-fifth of ischaemic strokes, with a high risk of early recurrence. Oral anticoagulation is highly effective for reducing the long-term risk of recurrent ischaemic stroke in patients with AF. However, its benefit in the acute phase is unclear. OPTIMAS is an RCT aiming to establish the safety and efficacy of early anticoagulation with a direct oral anticoagulant (DOAC). Available evidence and guidelines emphasise the lack of evidence to guide clinicians and support continued randomisation into trials including OPTIMAS. Method(s): OPTIMAS will enrol 3,478 participants with ischaemic stroke and AF from 100+ stroke services in the UK. Participants are randomised 1:1 to early (within 4 days) or standard (day 7 to 14 after stroke) initiation of anticoagulation. Follow-up is at 90 days, blinded to treatment allocation. The primary outcome is the incidence of stroke of any cause, and systemic arterial embolism. Result(s): OPTIMAS opened in June 2019 and is recruiting from 95 sites. 2,053 participants have been randomised as of 29th June 2022. Recruitment and site-set up were reduced during the COVID-19 pandemic, due to national lockdowns and hospital staff being reallocated to COVID-related trials. This did temporarily slow recruitment, but we rapidly developed a successful contingency plan to face these challenges, implementing strategies including: collecting the 90-day follow-ups centrally;obtaining consents by phone;and encouraging sites to sign up to the NIHR Associate PI Scheme to help with trial-related activities. For the last 10 months the trial has consistently been recruiting at least 80 participants per month. Conclusion(s): OPTIMAS will determine the efficacy and safety of early anticoagulation in patients with ischaemic strokes and AF. The trial recruited successfully during the most challenging period of the COVID- 19 pandemic and continues to do so.

Neurologic Manifestations of COVID-19.

Coronavirus disease (COVID-19) caused by a new coronavirus, SARS-CoV-2, has become a serious health problem throughout the world. Although COVID-19 primarily presents as an acute respiratory tract infection, many neurological findings have also been described in patients. Neurological findings are classified into three groups as central, peripheral nervous system and musculoskeletal system. The most common central nervous system symptom is headache. Encephalitis, encephalopathy, seizures, acute ischemic stroke are also seen. The most common symptoms in the peripheral nervous system are loss of smell and taste. Myalgia, myositis and rhabdomyolysis also can be seen in musculoskeletal system involvement. Awareness of the neurological symptoms by physicians will be beneficial in early diagnosis and treatment of the disease.Copyright © 2022 Ankara Pediatric Hematology Oncology Training and Research Hospital.

Acute ischemic stroke due to floating thrombus of ascending aorta: An acute and subacute complication of SARS-CoV-2 infection

Objective: To describe ischemic stroke due to floating thrombus of ascending aorta occurring as acute and subacute complication of SARS-CoV-2 infection. Material(s) and Method(s): consecutive identification in clinical practice of ischemic strokes secondary to aortic arch thrombosis and history of acute or recent Covid-19 infection. Result(s): two patients had ischemic stroke with evidence of aortic arch thrombosis. The first case had concomitant acute Covid-19 infection, the second had recent Covid-19 infection. Both patients underwent intravenous thrombolysis, and subsequent anticoagulation. One patient died due to cerebral hemorrhage. Discussion and Conclusion(s): aortic arch thrombosis can be an incidental finding in acute ischemic stroke in patients with concomitant and recent COVID-19 disease. However, the infection may lead to thrombosis in non-atherosclerotic vessels and to cerebral embolism. Our findings support active radiological search for aortic thrombosis during acute stroke in patients with acute or recent COVID-19 disease.Copyright © 2022

Implementing and managing nurse led reviews of patient outcomes at 3 and 6 months following mechanical thrombectomy for acute ischaemic stroke

Introduction: 90% of patients undergoing mechanical thrombectomy (MT) require collection of a 90-day outcome (Sacks et al, 2018). This paper presents the development and operation of a Stroke clinical nurse specialist (CNS) led, telephone thrombectomy outcome clinic at a Comprehensive stroke centre (CSC). The clinic was funded and included within the CNS role. The CNS completed formal mRS training. Service managers created a template for the clinic e.g., appointment duration, frequency, and volume. The CNS curated appointments at 90days & 6 months +/- 14 days. Clinics operated weekly (10-20 patients/month) in structured 15-minute appointments. Multiple 'Did not attend's' (DNA) outcome data was obtained via GP and next of kin. Method(s): Outcome completion and DNA rates were compared from 2019- 2021 from hospital systems. A survey for stroke consultants captured perceived benefits and challenges. Result(s): Outcome completion for 2019 was 97.6% (n=164), 2020 86.9% (n=145) and 2021 99% (n=101). 2020 data was temporarily impacted by stroke CNS staffing change and the coronavirus pandemic. DNA rates reduced between 2019 - 2021 for 3 month (18% to 17%) and 6-month reviews (19% to 11%). 100% of stroke consultants agreed outcome data is vital for the service (6/6). Perceived benefits were quality assurance, standardisation, governance, and clinical continuity. Practical challenges included room availability, following up DNA's and the use of interpreters. Conclusion(s): CSC's can achieve >90% of MT case outcomes with mRS trained CNS led clinics. They provide standardised, reliable, and vital patient outcomes for improving MT services.

Neuropsychiatric Manifestations of COVID-19 in Hospitalized Pediatrics: A Multicenter Cross-sectional Study

Background: The large proportion of coronavirus disease 2019 (COVID-19) patients has been associated with a large number of neu-ropsychiatric manifestations. Despite the high prevalence of COVID-19, few studies have examined such manifestations, especially in children and adolescents. Objective(s): This study investigated neuropsychiatric manifestations in hospitalized children and adolescents admitted for COVID-19 infection in Iran. Method(s): This prospective observational study included admitted children and adolescents (4-18 years old) diagnosed with COVID-19 infection, pediatric neurologists, child and adolescent psychiatrists, and infectious disease specialists, and assessed 375 infected patients during August and December 2021. Result(s): Of the 375 patients, 176 (47%) were female, with a mean age of 9.0 +/- 3.39 years. Psychiatric and neurological manifestations were reported in 58 (15.5%) and 58 (15.5%) patients, respectively. The most prevalent psychiatric disorders were separation anxiety disorder (SAD) (5.1%), major depressive disorder (MDD) (3.5%), generalized anxiety disorder (GAD) (2.7%), insomnia (2.4%), and op-positional defiant disorder (ODD) (2.4%). Regarding neurological complications, seizures were the most prevalent (13.1%), followed by encephalitis (1.9%), transverse myelitis (0.3%), acute ischemic stroke (0.3%), and Guillain-Barre syndrome (0.3%). There was no significant relationship between the duration of COVID-19 infection (P = 0.54) and ICU admission (P = 0.44) with the emergence of psychiatric symptoms. Conclusion(s): The most prevalent neurologic and psychiatric complications among children and adolescents with COVID-19 infection were seizures and the symptoms of anxiety/mood disorders, respectively.Copyright © 2023, Author(s).

Outcome of COVID-19-Associated Acute Stroke: A Study from South India.

Background and Objective: Coronavirus 2019 (COVID-19) infection is prevalent worldwide. COVID-19 infection can lead to various neurological disorders including acute stroke. We investigated the functional outcome and its determinants among our patients with acute stroke associated with COVID-19 infection in the present setup. Materials and Methods: This study is a prospective study in which we recruited acute stroke patients with COVID-19 positivity. Data on duration of COVID-19 symptoms and type of acute stroke were recorded. All patients underwent stroke subtype workup and measurement of D-dimer, C-reactive protein (CRP), lactate-dehydrogenase (LDH), procalcitonin, interleukin-6, and ferritin levels. Poor functional outcome was defined by modified Rankin score (mRS) ≥3 at 90 days. Results: During the study period, 610 patients were admitted for acute stroke, of whom 110 (18%) tested positive for COVID-19 infection. Majority (72.7%) were men with a mean age of 56.5 years and mean duration of COVID-19 symptoms for 6.9 days. Acute ischemic and hemorrhagic strokes were observed in 85.5% and 14.5% patients, respectively. Poor outcome was observed in 52.7%, including in-hospital mortality in 24.5% patients. COVID-19 symptoms ≤5 days (odds ratio [OR]: 1.41, 95% confidence interval [CI]: 1.20-2.99), CRP positivity (OR: 1.97, 95% CI: 1.41-4.87), elevated levels of D-dimer (OR: 2.11, 95% CI: 1.51-5.61), interleukin-6 (OR: 1.92, 95% CI: 1.04-4.74), and serum ferritin (OR: 2.4, 95% CI: 1.02-6.07), and cycle threshold (Ct) value ≤25 (OR: 8.8, 95% CI: 6.52-12.21) were independent predictors of poor outcome. Conclusion: Poor outcomes were relatively higher among acute stroke patients with concomitant COVID-19 infection. In the present study, we established the independent predictors of poor outcome to be onset of COVID-19 symptoms (<5 days) and elevated levels of CRP, D-dimer, interleukin-6, ferritin, and Ct value ≤25 in acute stroke.

Patterns of acute ischemic stroke and intracranial hemorrhage in patients with COVID-19 : Results of a retrospective multicenter neuroimaging-based study from three central European countries.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is an infection which can affect the central nervous system. 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 METHODS: Retrospective 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. RESULTS: 442 patients could be included. COVID-19 severity was mild in 124 (28.1%) patients (moderate n = 134/30.3%, severe n = 43/9.7%, critical n = 141/31.9%). 220 patients (49.8%) presented with respiratory symptoms, 167 (37.8%) presented with neurological symptoms first. Acute ischemic stroke (AIS) was detected in 70 (15.8%), intracranial hemorrhage (IH) in 48 (10.9%) patients. Typical risk factors were associated with AIS; extracorporeal membrane oxygenation therapy and invasive ventilation with IH. No association was found between the severity of COVID-19 or blood/CSF parameters and the occurrence of AIS or IH. DISCUSSION: AIS was the most common finding on cranial imaging. IH was more prevalent than expected but a less common finding than AIS. Patients with IH had a distinct clinical profile compared to patients with AIS. There was no association between AIS or IH and the severity of COVID-19. A considerable proportion of patients presented with neurological symptoms first. Laboratory parameters have limited value as a screening tool.
