Enhanced Interplay of Neuronal Coherence and Coupling in the Dying Human Brain.

The neurophysiological footprint of brain activity after cardiac arrest and during near-death experience (NDE) is not well understood. Although a hypoactive state of brain activity has been assumed, experimental animal studies have shown increased activity after cardiac arrest, particularly in the gamma-band, resulting from hypercapnia prior to and cessation of cerebral blood flow after cardiac arrest. No study has yet investigated this matter in humans.

Cost-effectiveness analysis in patients with an unruptured cerebral aneurysm treated with observation or surgery.

Objective: The main goal of preventive treatment of unruptured intracranial aneurysms (UIAs) is to avoid the morbidity and mortality associated with aneurysmal subarachnoid hemorrhage. A comparison between the conservative approach and the surgical approach combining endovascular treatment and microsurgical clipping is currently lacking. This study aimed to conduct an updated evaluation of cost-effectiveness comparing the two approaches in patients with UIA.

Basilar Apex Aneurysm: Case Series, Systematic Review, and Meta-analysis.

Background: A lower rate of aneurysmal recanalization in stent assisted coiling versus coiling alone has been observed in aneurysms overall. This study aims to primarily stratify and compare degree of occlusion per treatment modality in basilar apex aneurysms. Secondary outcomes were retreatment, posttreatment hemorrhage, and procedure-related complications.

Cannabis use and outcomes after aneurysmal subarachnoid hemorrhage: A nationwide retrospective cohort study.

Background: Cannabis is the most consumed recreational drug in the world. It is possible that cannabis has an association with an increased risk of vasospasm-related strokes and delayed cerebral ischemia (DCI), which are major causes of morbidity and mortality in aneurysmal subarachnoid hemorrhage (aSAH). Hence, this study aimed to explore the independent relationship between cannabis use and outcomes after aSAH using the 2016 United States Nationwide Inpatient Sample.

Headache Outcomes After Treatment of Unruptured Intracranial Aneurysm: A Systematic Review and Meta-Analysis.

Background and Purpose- While unruptured intracranial aneurysms may be discovered incidentally in the workup of chronic headache, it remains unclear whether their treatment ultimately impacts headache severity. We aim to conduct a systematic review and meta-analysis assessing headache severity after treatment of unruptured intracranial aneurysm. Methods- MEDLINE and EMBASE were systematically reviewed.

Midline cerebellar medulloblastoma in a seventy-one-year-old patient.

Background: Medulloblastoma is the most common malignant central nervous system tumour in children but, in contrast, quite rare in adults. Hemispheric, rather than midline, cerebellar medulloblastomas are more common in older children and adults. We present the unusual case of a 71-year-old man who presented with a fourth ventricular mass that proved to be a medulloblastoma.

Complications of embolization of arteriovenous malformations of the brain.

Object: The goal of this study was to determine the rates of mortality and morbidity associated with the embolization of arteriovenous malformations (AVMs) of the brain and to analyze the factors related to embolization-related complications.

Methods: The University of Toronto Brain Vascular Malformation Study Group database was reviewed. Three hundred six patients underwent 513 embolization sessions between November 1984 and September 2002.

Rare intracanalicular ophthalmic aneurysm: endovascular treatment and review of the literature.

This report outlines the diagnosis and endovascular management of a rare intracanalicular ophthalmic aneurysm in a patient presenting with progressive visual loss.
