Background: Delirium is an acute cognitive disturbance frequently characterized by abnormal psychomotor activity and sleep-wake cycle disruption. However, the degree to which delirium affects activity patterns in the acute period after stroke is unclear. We aimed to examine these patterns in a cohort of patients with intracerebral hemorrhage (ICH).
Methods: We enrolled 40 patients with intracerebral hemorrhage (ICH) who had daily DSM-5-based delirium assessments. Continuous activity measurements were captured using bilateral wrist actigraphs throughout each patient's admission. Activity data were collected in 1-min intervals, with "rest" defined as periods with zero activity. We compared differences in activity based on delirium status across multiple time intervals using multivariable models adjusted for age, ICH severity, and mechanical ventilation.
Results: There were 279 days of actigraphy monitoring, of which 199 (71%) were rated as days with delirium. In multivariable analyses, delirium was associated with 98.4 (95% CI 10.4-186.4) fewer daily minutes of rest, including 5.3% (95% CI -0.1-10.1%) fewer minutes during daytime periods (06:00-21:59) and 10.2% (95% CI 1.9-18.4%) fewer minutes during nocturnal periods (22:00-5:59), with higher levels of activity across multiple individual hourly intervals (18:00-21:00, 23:00-03:00, and 04:00-08:00). These differences were even more pronounced in hyperactive or mixed delirium, although even hypoactive delirium was associated with more activity during multiple time periods.
Conclusions: Post-stroke delirium is associated with less rest and higher overall levels of activity, especially during nocturnal periods.

Hemorrhagic stroke occurs due to a rupture of a blood vessel in the brain. This leads to initial mechanical damage at the site of injury and secondary injuries including axonal degeneration (AxD). Since axons are critical for all brain functions, we systematically reviewed studies that focused on axonal degeneration in two major types of hemorrhagic stroke, intracerebral hemorrhage and subarachnoid hemorrhage, to understand how and to what extent AxD develops and to interrogate underlying mechanisms and potential therapeutic targets.

Arteriovenous malformations (AVMs) are abnormal connections between cerebral arteries and veins that lack an intervening capillary bed. Brain AVMs affect approximately 0.1% of the population and are diagnosed in 1.

Background And Objectives: Previous studies addressing the association between multiple sclerosis (MS) and stroke yielded conflicting results. The current study aimed to evaluate the association between MS and incident stroke, overall and by main stroke subtypes.
Methods: We conducted a population-based retrospective cohort study utilizing the Clalit Health Services database, the largest healthcare provider in Israel.

Objectives: Elevated intracranial pressure (ICP) is a complication of severe traumatic brain injury (TBI) that carries a risk of secondary brain injury. This study investigated the association between ICP burden and brain injury patterns on MRI in children with severe TBI.
Design, Setting, And Patients: Secondary analysis of the Approaches and Decisions in Acute Pediatric TBI (ADAPT) study, which included children with severe TBI (Glasgow Coma Scale score < 9) who received a clinical MRI within 30 days of injury.

Background: To assess the efficacy and safety of tenecteplase in patients presenting within 24 hours of symptom onset with a large vessel occlusion and target mismatch on perfusion computed tomography.
Methods: ETERNAL-LVO was a prospective, randomized, open-label, blinded end point, phase 3, superiority trial where adult participants with a large vessel occlusion, presenting within 24 hours of onset with salvageable tissue on computed tomography perfusion, were randomized to tenecteplase 0.25 mg/kg or standard care across 11 primary and comprehensive stroke centers in Australia.
