Percutaneous Cerebral Angioplasty for Refractory Middle Cerebral Artery Stenosis Due to Varicella-Zoster Virus-Related Vasculopathy: A Case Report.

An 81-year-old man was admitted to our hospital with left hemiplegia after treatment for herpes zoster of the first branch of the right trigeminal nerve. CSF examination revealed an elevated varicella-zoster virus (VZV) antibody index. Brain MRI showed cerebral infarction in the right middle cerebral artery (MCA) territory and vessel wall thickening and enhancing effects at the ipsilateral MCA.

A Novel Mutation of VPS13D-related Disorders with Parkinsonism.

We herein report a case of VPS13D-related disorder with a novel homogeneous variant. A 58-year-old Japanese woman was referred to our hospital with slowly progressive gait disturbance and cognitive impairment. A neurological examination revealed decreased spontaneity, recent memory impairment, parkinsonism, cerebellar ataxia, pyramidal signs, and autonomic dysfunction.

Interictal epileptiform discharges as a predictive biomarker for recurrence of poststroke epilepsy.

Poststroke epilepsy is a major ischaemic/haemorrhagic stroke complication. Seizure recurrence risk estimation and early therapeutic intervention are critical, given the association of poststroke epilepsy with worse functional outcomes, quality of life and greater mortality. Several studies have reported risk factors for seizure recurrence; however, in poststroke epilepsy, the role of EEG in predicting the risk of seizures remains unclear.

Association of Cortical Superficial Siderosis with Post-Stroke Epilepsy.

Objective: To assess whether post-stroke epilepsy (PSE) is associated with neuroimaging findings of hemosiderin in a case-control study, and whether the addition of hemosiderin markers improves the risk stratification models of PSE.

Methods: We performed a post-hoc analysis of the PROgnosis of POST-Stroke Epilepsy study enrolling PSE patients at National Cerebral and Cardiovascular Center, Osaka, Japan, from November 2014 to September 2019. PSE was diagnosed when one unprovoked seizure was experienced >7 days after the index stroke, as proposed by the International League Against Epilepsy.

Statin treatment can reduce incidence of early seizure in acute ischemic stroke: A propensity score analysis.

A previous study showed early statin administration in patients with acute ischemic stroke (AIS) was associated with a lower risk of early-onset seizure (ES), which is a high risk of epilepsy, but this retrospective study design may not have eliminated confounding factor effects. We aimed to verify the determinants and prognostic significance of ES and clarify the effects of statin administration. Consecutive AIS patients without a history of epilepsy were enrolled.

Risk Factors for Nonconvulsive Status Epilepticus after Stroke.

Background: Status epilepticus (SE) sometimes occurs after stroke. SE is classified as convulsive SE (CSE) and nonconvulsive SE (NCSE). Clinical characteristics, outcomes, mortality, and recurrences of post-stroke NCSE are yet to be clarified.

Early Achievement of Blood Pressure Lowering and Hematoma Growth in Acute Intracerebral Hemorrhage: Stroke Acute Management with Urgent Risk-Factor Assessment and Improvement-Intracerebral Hemorrhage Study.

Background: Previous studies have revealed that hematoma growth mainly occurs during the first 6 h after the onset of spontaneous intracerebral hemorrhage (ICH). Early lowering of blood pressure (BP) may be beneficial for preventing hematoma growth. However, relationships between timing of BP lowering and hematoma growth in ICH remain unclear.

Nonconvulsive Status Epilepticus in Acute Intracerebral Hemorrhage.

Background And Purpose: Patients with acute intracerebral hemorrhages (ICHs) often develop nonconvulsive status epilepticus (NCSE). We aimed to identify determinants and the prognostic significance of NCSE among patients with acute ICH.

Methods: Consecutive patients with acute spontaneous ICH who were admitted to a comprehensive stroke center were enrolled.

Two-Year Outcomes of Anticoagulation for Acute Ischemic Stroke With Nonvalvular Atrial Fibrillation - SAMURAI-NVAF Study.

Background: We determined the 2-year long-term risk-benefit profile in patients with stroke or transient ischemic attack (TIA) receiving warfarin or direct oral anticoagulants (DOACs) for nonvalvular atrial fibrillation (NVAF) using a prospective, multicenter, observational registry in Japan.

Methods and results: NVAF patients within 7 days after onset of ischemic stroke/TIA were enrolled in 18 stroke centers. Outcome measures included ischemic and bleeding events and death in the 2-year follow-up period.

Urgent Detection of Acute Type A Aortic Dissection in Hyperacute Ischemic Stroke or Transient Ischemic Attack.

Background And Purpose: Urgent diagnosis of acute Stanford type A aortic dissection (AAD) in patients with acute ischemic stroke (AIS) or transient ischemic attack (TIA) is sometimes challenging. We assessed predictive values for markers of AAD in patients with AIS or TIA.

Methods: Consecutive patients with AIS or TIA with AAD who presented to our emergency room within 4.

Cerebrovascular imaging of cerebral ischemia in acute type A aortic dissection.

Background And Purpose: Stanford type A aortic dissection (AAD) sometimes causes acute ischemic stroke (AIS) or transient ischemic attack (TIA). There is little understanding of cerebrovascular imaging of AIS or TIA in patients with AAD.

Methods: Consecutive AIS/TIA patients with AAD who were admitted within 4.

Risk factors for post-stroke seizure recurrence after the first episode.

Purpose: Seizure is a common complication after stroke. However, the clinical characteristics, treatment, and recurrence rates in patients with the first episode of post-stroke seizure remain unclarified. The aim of this study was to identify the predictors of seizure recurrence in those patients.

Frequency and Detection of Stanford Type A Aortic Dissection in Hyperacute Stroke Management.

Background And Purpose: Acute Stanford type A aortic dissection (AAD) is a devastating aortic disease, and prompt diagnosis is sometimes difficult to make. Identification of AAD in suspected acute stroke patients is especially challenging. Nevertheless, the frequencies and predictive factors of AAD in suspected acute stroke patients have not been well investigated.

[Angiographically documented hemorrhagic transformation of embolic stroke: A case report].

A 81-year-old man with rheumatoid vasculitis presented with total aphasia followed by right hemiplegia. The NIHSS score was 24. Diffusion weighted magnetic resonance imaging (DWI) demonstrated an acute infarct in the left middle cerebral artery (MCA) territory, and magnetic resonance angiogram (MRA) revealed left MCA M1 occlusion.
