Cerebral infarct volume measurements to improve patient selection for endovascular treatment.

Patients who have large cerebral infarctions may not be good candidates for endovascular treatment. Various methods for determining infarct volume have been used in clinical studies. We evaluated the effectiveness of several methods for measuring infarct volume, especially regarding futile outcomes despite endovascular treatment.

Prevalence of antineuronal antibodies in patients with encephalopathy of unknown etiology: Data from a nationwide registry in Korea.

We aimed to evaluate the prevalence of antineuronal antibodies in a nationwide cohort of patients with encephalopathy of unknown etiology. We screened 1699 patients with idiopathic encephalopathy who were referred from 70 hospitals across Korea for autoimmune synaptic and classic paraneoplastic antibodies. Those with cerebellar degeneration, sensory polyneuropathy or other paraneoplastic syndromes without encephalopathy were not included in this study.

Effect of Immunotherapy on Seizure Outcome in Patients with Autoimmune Encephalitis: A Prospective Observational Registry Study.

Objective: To evaluate the seizure characteristics and outcome after immunotherapy in adult patients with autoimmune encephalitis (AE) and new-onset seizure.

Methods: Adult (age ≥18 years) patients with AE and new-onset seizure who underwent immunotherapy and were followed-up for at least 6 months were included. Seizure frequency was evaluated at 2-4 weeks and 6 months after the onset of the initial immunotherapy and was categorized as "seizure remission", "> 50% seizure reduction", or "no change" based on the degree of its decrease.

Primary stent retrieval for acute intracranial large artery occlusion due to atherosclerotic disease.

Background And Purpose: The goal of stent retriever-based thrombectomy is removal of embolic clots in patients with intracranial large artery occlusion. However, outcomes of stent retrieval may differ between acute arterial occlusions due to intracranial atherosclerotic disease (IAD) and those due to embolism. This case series describes the outcomes of stent retriever-based thrombectomy and rescue treatments in 9 patients with IAD-related occlusion.

Endovascular Therapy of Cerebral Arterial Occlusions: Intracranial Atherosclerosis versus Embolism.

Background: Treatment strategy for acute arterial occlusions due to intracranial atherosclerotic disease (IAD) may differ from those due to embolism (embolic). The aims were to differentiate and classify angiographically defined occlusion due to IAD versus embolism and identify baseline clinical factors associated with IAD-related occlusion.

Methods: Acute ischemic stroke patients with large cerebral artery occlusions on computed tomography angiography who underwent transfemoral cerebral angiography for endovascular treatment were included.

Epileptic nystagmus: A case report and systematic review.

Purpose: We aimed to define the characteristics of epileptic nystagmus and correlate those with other clinical findings in a large number of patients.

Methods: We report a patient with epileptic nystagmus and additionally reviewed the reported clinical features of 36 more patients through a systematic literature search. We analyzed the characteristics of epileptic nystagmus and attempted correlations of those with alertness of the patients and epileptic foci on EEG.
