Article Synopsis
  • Tranexamic acid, an antifibrinolytic agent, was tested in a study on patients with intracerebral hemorrhage who had ongoing bleeding (spot signs) to assess its effect on hematoma growth when administered within 4.5 hours of onset.
  • A systematic review and meta-analysis were conducted, evaluating randomized trials comparing tranexamic acid to a placebo, specifically including 162 participants with follow-up imaging.
  • Results showed that tranexamic acid treatment did not significantly reduce hematoma growth compared to placebo, with a slightly lower growth rate in the treatment group, but overall outcomes suggested continued monitoring and assessment of safety was needed.

Article Synopsis
  • A study investigated the characteristics of asymptomatic diffusion-weighted imaging-positive (aDWI+) lesions in CADASIL patients, using data from the Taiwan CADASIL Registry.
  • Out of 154 patients, 11% had aDWI+ lesions, which were linked to a higher prevalence of small vessel disease markers, like lacunes and cerebral microbleeds, compared to patients without these lesions.
  • The research found that aDWI+ lesions were smaller and less likely to impact critical brain areas compared to symptomatic diffusion-weighted imaging-positive (sDWI+) lesions, highlighting the need for further investigation into their long-term effects.

Despite recent findings indicating a paradoxical association between high-density lipoprotein cholesterol (HDL-C) levels and cardiovascular disease (CVD) mortality, the impact of HDL-C on subsequent outcomes after ischemic stroke remains unclear. The study aims to investigate the relationships between HDL-C levels and post-stroke functional outcomes while examining the potential modifying influence of HDL-C-related single nucleotide polymorphisms identified through genome-wide association studies. This cohort study included 1,310 patients diagnosed with acute ischemic stroke (AIS), all of whom had their admission serum lipid profile and genotyping information.

Tau, a hallmark of Alzheimer's disease, is poorly characterized in cerebral amyloid angiopathy. We aimed to assess the clinico-radiological correlations between tau positron emission tomography scans and cerebral amyloid angiopathy. We assessed cerebral amyloid and hyperphosphorylated tau in patients with probable cerebral amyloid angiopathy ( = 31) and hypertensive small vessel disease ( = 27) using C-Pittsburgh compound B and F-T807 positron emission tomography.

Accurately predicting the prognosis of ischemic stroke patients after discharge is crucial for physicians to plan for long-term health care. Although previous studies have demonstrated that machine learning (ML) shows reasonably accurate stroke outcome predictions with limited datasets, to identify specific clinical features associated with prognosis changes after stroke that could aid physicians and patients in devising improved recovery care plans have been challenging. This study aimed to overcome these gaps by utilizing a large national stroke registry database to assess various prediction models that estimate how patients' prognosis changes over time with associated clinical factors.

Purpose: Carotid artery web (CaW) is a rare focal fibromuscular dysplasia that can lead to embolic strokes with large vessel occlusion. This condition can be effectively treated with endovascular thrombectomy (EVT). Our study aims to assess the prevalence of CaW among patients with acute ischemic stroke (AIS) who underwent EVT and to compare the clinical characteristics of CaW with other carotid artery pathologies.

Background: Early mobilization (EM) within 24 to 72 hours post-stroke may improve patients' performance and ability. However, after intravenous thrombolysis (IVT) or mechanical thrombectomy (MT), the increased risk of hemorrhagic complications impacts the implementation of early out-of-bed mobilization. Few studies have investigated EM after IVT or MT for acute ischemic stroke (AIS), and its impact in these patients is unknown.

Lobar cerebral microbleeds are a characteristic neuroimaging finding in cerebral amyloid angiopathy (CAA) but can also be found in hypertensive arteriolosclerosis. We aimed to investigate whether CAA is more associated with intracortical lobar microbleeds than hypertensive arteriosclerosis. Ninety-one survivors of spontaneous intracerebral hemorrhage with at least one lobar microbleed were included and underwent brain MRI and amyloid PET.
