Coronavirus disease 2019 (COVID-19) is a global pandemic that causes flu-like symptoms. There is a growing body of evidence suggesting that both the central and peripheral nervous systems can be affected by SARS-CoV-2, including stroke. We present three cases of arterial ischemic strokes and one venous infarction from a cerebral venous sinus thrombosis in the setting of COVID-19 infection who otherwise had low risk factors for stroke. ⋯ It is important to recognize the neurological manifestations of COVID-19, especially ischemic stroke, either arterial or venous in nature. Hypercoagulability and the cytokine surge are perhaps the cause of ischemic stroke in these patients. Further studies are needed to understand the role of anticoagulation in these patients.

Comparative Study
Aneurysmal subarachnoid hemorrhage in patients with migraine and tension headache: A cohort comparison study.
Migraine headache is a common condition with an estimated lifetime prevalence of greater than 20%. While it is a well-established risk factor for cardiovascular disease and ischemic stroke, its association with subarachnoid hemorrhage is largely unexplored. We sought to compare the incidence of aneurysmal subarachnoid hemorrhage in a cohort of migraine patients with a cohort of patients with tension headache. ⋯ CPH regression on matched data showed that treated migraine patients had a significantly lower hazard of aneurysmal subarachnoid hemorrhage compared with tension headache patients (HR = 0.40, 95% CI: 0.19 - 0.86, p = 0.02). This large cohort comparison study, analyzing more than 679,000 patients, demonstrated that migraine patients undergoing pharmacologic treatment had a lower hazard of aneurysmal subarachnoid hemorrhage than patients diagnosed with tension headaches. Future work specifically focusing on migraine medications may identify the mechanisms underlying this association.

Case Reports
Vasculitis-related stroke in young as a presenting feature of novel coronavirus disease (COVID19) - Case report.
COVID-19 is the disease caused by Novel Coronavirus (SARS-CoV-2) infection and world current main public health problem, due to its easy transmissibility and multiple clinical presentations. The main symptoms reported worldwide are dry cough, dyspnea, and fever, as well as anosmia and ageusia. COVID-19 diagnosis is made with RT-PCR, but many other complementary exams may be used to guide clinical practice, such as Chest Computerized Tomography (CT), showing ground glass opacities; increase in inflammatory markers, as C-Reactive Protein and Erythrocyte Sedimentation Rate; hemogram might show hypoalbuminemia, thrombocytopenia. ⋯ Underwent brain MRI and serum serological analysis. SARS-CoV-2 capacity of affecting brain homeostasis by breaking blood-brain barrier, makes it easier to develop ischemic or inflammatory damage, and invading central nervous system. Neurological symptoms and syndromes are the main consequences of COVID-19 pandemic and must be prevented through adequate clinical management.

We describe a patient affected by Covid-19 acute respiratory distress syndrome with a cerebral nervous system vasculitis triggered by SARS-Cov-2, managed at the University hospital, in Novara, Italy in the area most impacted by the pandemic and where 749 Covid-19 positive patients were admitted from March 1st until April 25th, 2020.

COVID-19 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which was first reported in Wuhan, China in December 2019, and is ongoing pandemic. While a majority of patients with SARS-CoV-2 infection shows asymptomatic or mild disease, hospitalized patients can develop critical condition, such as pneumonia, sepsis, and respiratory failure. Some cases deteriorate into sever systemic disease and multiorgan failure. ⋯ Brain CT and MRI showed typical images of CVT in the left transvers sinus and CT pulmonary angiography showed PE. Administration of unfractionated heparin followed by edoxaban treatment reduced the levels of D-dimer and improved his clinical presentation and thrombosis. Monitoring coagulopathy is important in COVID-19 patients and in case of venous thromboembolism, including cerebral venous system, appropriate anticoagulant therapy should be initiated.
