A stroke is a life-threatening medical condition that could be disabling if left untreated. Intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) can be effective when initiated in an acute stroke, but their benefit is time-dependent and their use may be restricted by contraindications (CIs) such as anticoagulation therapy. The critical therapeutic time window, which was previously limited to 4.5-6 hours, is now extended to 24 hours in selected patients due to the development of advanced neuroimaging techniques. Herein, we discuss the case of a 50-year-old patient on rivaroxaban who developed acute ischemic stroke (AIS) and was treated successfully with intravenous recombinant tissue plasminogen activator thrombolysis more than six hours after the time he was last seen well (LSW). Our case demonstrates the importance of advanced neuroimaging techniques in identifying AIS candidates for IVT and/or MT with late or unknown time windows as well as the importance of case-by-case assessment when challenged by theoretical contraindications for thrombolysis.

Objective: This study investigated the effects of early treatment and pathophysiology on eosinophilic granulomatosis with polyangiitis neuropathy (EGPA-N).
Methods: Twenty-six consecutive patients with EGPA-N were diagnosed and treated within a day of admission and underwent clinical analysis. Peripheral nerve recovery rates were evaluated after early treatment by identifying the damaged peripheral nerve through detailed neurological findings.
The challenge of long-term stroke outcome prediction and how statistical correlates do not imply predictive value.

Personalized prediction of stroke outcome using lesion imaging markers is still too imprecise to make a breakthrough in clinical practice. We performed a combined prediction and brain mapping study on topographic and connectomic lesion imaging data to evaluate (i) the relationship between lesion-deficit associations and their predictive value and (ii) the influence of time since stroke. In patients with first-ever ischaemic stroke, we first applied high-dimensional machine learning models on lesion topographies or structural disconnection data to model stroke severity (National Institutes of Health Stroke Scale 24 h/3 months) and functional outcome (modified Rankin Scale 3 months) in cross-validation.

Introduction: Delirium, frequently experienced by ischemic stroke patients, is one of the most common neuropsychiatric syndromes reported in the Intensive Care Unit (ICU). Stroke patients with delirium have a high mortality rate and lengthy hospitalization. For these reasons, early diagnosis of delirium in the ICU is critical for better patient prognosis.

Ischemic stroke is one of the major emergency diseases leading to death and disability worldwide, characterized by its acute onset and the urgent need for prompt medical intervention to reduce mortality and long-term disability. Chronic terminal internal carotid artery and/or middle cerebral artery occlusion (CTI/MCAO) is an important subtype of intracranial artery occlusive disease. The superficial temporal artery-to-MCA (STA-MCA) bypass has been proposed to improve cerebral blood flow (CBF) and cerebrovascular reserve (CVR), potentially enhancing neurological outcomes.

Background: Malnutrition is a significant challenge in stroke patients, affecting both rehabilitation and independence. This study aims to evaluate whether early L-carnitine supplementation can effectively improve anthropometric parameters and malnutrition status in acute-phase ischemic stroke patients to mitigate the catabolic state.
Methods: Eighty-two first-ever ischemic stroke patients were randomly assigned to either the L-carnitine group (1000 mg three times/day for seven consecutive days) or the matching placebo group.
