Aim - identify neuroimaging characteristics associated with different post-stroke fatigue (PSF) domains within first 6 months after ischemic strokes. There were enrolled in the study 107 patients with acute ischemic strokes. General PSF and certain PSF domains (global, physical, mental, motivational, activity-related) were measured by multidimensional fatigue inventory-20 (MFI-20) scale at hospital stay, in 1, 3 and 6 months after stroke occurrence. Brain MRI studies included cerebral infarct localization, planimetric measurements of infarct volumes, measurement of brain atrophy indexes (bifrontal, bicaudate, cortical atrophy indexes, width of third ventricle) and evaluation of leukoaraiosis severity, according to Fazekas scale...

PURPOSE: The severity of white matter lesions (WML) is a risk factor of hemorrhage and predictor of clinical outcome after ischemic stroke; however, in contrast to magnetic resonance imaging (MRI) reliable quantification for this surrogate marker is limited for computed tomography (CT), the leading stroke imaging technique. We aimed to present and evaluate a CT-based automated rater-independent method for quantification of microangiopathic white matter changes. METHODS: Patients with suspected minor stroke (National Institutes of Health Stroke scale, NIHSS < 4) were screened for the analysis of non-contrast computerized tomography (NCCT) at admission and compared to follow-up MRI...

Development of laboratory diagnosis and neuroimaging revealed a number of biomarkers for in vivo diagnosis of the most common forms of dementia (Alzheimer's disease, Lewy body dementia and vascular dementia). Currently, the highest diagnostic sensitivity and specificity of molecular biomarkers in the cerebrospinal fluid are detected for Alzheimer's disease. At the same time, the changes according to the magnetic resonance imaging are more prognostically significant for future cognitive decline than cerebrospinal fluid biomarkers...

Higher blood pressure, blood pressure variability, and leukoaraiosis are risk factors for early adverse events and poor functional outcome after ischemic stroke, but prior studies differed on whether leukoaraiosis was associated with blood pressure variability, including in ischemic stroke. In the Third International Stroke Trial, blood pressure was measured in the acute phase of ischemic stroke immediately prior to randomization, and at 0.5, 1, and 24 h after randomization. Masked neuroradiologists rated index infarct, leukoaraiosis, and atrophy on CT using validated methods...

Leukoaraiosis (LA) is one of the neuroimaging features of cerebral small vessel disease and is associated with poor long-term prognosis. Areas covered: This narrative review focuses on the predictive role of LA on the evolution of the ischemic brain damage and on the clinical outcome in the subacute phase of stroke and in the short-term period afterwards. Expert commentary: LA predicts poorer tissue outcome and clinical prognosis also in acute and subacute stroke. In acute stroke, LA is associated with a less favorable fate of brain infarct and is a marker of increased risk of thrombolysis-related hemorrhagic transformation...

Although short and long-term outcomes of aortic surgeries have been improving over the past decade, the procedure is likely to be asscociated with life-threatening complications such as neurological deficits caused by suboptimal brain protection or heavily diseased aorta. Contemporary strategies for brain protection are deep hypothermic arrest with or without retrograde cerebral perfusion retrograde cerebral perfusion or selective antegrade cerebral perfusion. At the moment, majority of evidences failed to show the superiority of selective antegrade cerebral perfusion to retrograde one...

The embolization of cancer cells to cerebral vessels occurs early in the multi-step metastatic process. We aimed to determine whether the presence of leukoaraiosis (LA) before treatment would predict the development of brain metastases (BM) in patients with lung cancer. Between January 2014 and June 2015, 1007 patients underwent initial (i.e., prior to any chemotherapy) or routine magnetic resonance (MR) imaging of the brain and exhibited no evidence of BM. Of these, 189 underwent repeat MR imaging; 34 of 189 patients (18%) developed new BM, whereas 155 patients did not...

Circular RNAs (circRNAs) are class of endogenous RNAs that have a role in the regulation of gene expression. The present study aimed to investigate the diagnostic value and role of circRNA in the pathogenesis of leukoaraiosis (LA). The present study performed Arraystar Human circRNA Array analysis of 6 samples from LA cases and 6 samples from control cases. Differentially expressed (DE) circRNAs between two samples were identified through fold‑change (>1.5‑fold) screening. Afterwards, based on DE circRNAs, the gene ontology (GO) analysis of upregulated DE genes identified from DE circRNAs demonstrated that DE genes were primarily associated with cellular metabolic processes, membrane‑bound organelles and binding...

OBJECTIVE: In people without previous stroke, covert findings on serial magnetic resonance imaging (MRI) of incident brain infarcts and worsening leukoaraiosis are associated with increased risk for ischemic stroke and dementia. We evaluated whether various measures of blood pressure (BP) and heart rate are associated with these MRI findings. APPROACH AND RESULTS: In the CHS (Cardiovascular Health Study), a longitudinal cohort study of older adults, we used relative risk regression to assess the associations of mean, variability, and trend in systolic BP, diastolic BP, and heart rate measured at 4 annual clinic visits between 2 brain MRIs with incident covert brain infarction and worsening white matter grade (using a 10-point scale to characterize leukoaraiosis)...

Leukoaraiosis is associated with increased risk of cognitive impairment, but its pathophysiological pathway is unclear. The aim of the present study was to determine whether brain structural damage or cerebral blood supply better correlated with the global cognitive outcome in subjects with leukoaraiosis. Seventy-five subjects with leukoaraiosis were included in present study, with age ranged from 43 to 85 years, with mean white matter hyperintensities (WMH) volume 30.69 ± 24.35 mL. Among them, 19(25.33%) subjects presented with cerebral microbleeds (CMB) and 40 (53...

BACKGROUND AND PURPOSE: Remote parenchymal haemorrhage (rPH) after intravenous thrombolysis is defined as hemorrhages that appear in brain regions without visible ischemic damage, remote from the area of ischemia causing the initial stroke symptom. The pathophysiology of rPH is not clear and may be explained by different underlying mechanisms. We hypothesized that rPH may have different risk factors according to the bleeding location. We report the variables that we found associated with deep and lobar rPH after intravenous thrombolysis...

Cerebral autosomal dominant arteriopathy with subcortical infarctions and leucoencephalopathy (CADASIL) is an inherited CNS disease, which is caused by mutations in the NOTCH3 gene. Selective disorders of small vessels underlie the disease pathogenesis. Clinically CADASIL is characterized by headaches, multiple stroke-like disorders (in most cases transient ischemic attacks and lacunar strokes), and different focal neurological symptoms and dementia. There are specific MRI signs of the disease: multiple lacunar infarctions located in the basal ganglia, brain steam and cerebellum, focal lesions of temporal poles, capsula externa, periventricular and subcortical areas; diffuse white matter changes and leukoaraiosis can be observed as well...

Cardioembolic stroke due to atrial fibrillation (AF) and/or rheumatic heart disease (RHD) often involves hemorrhagic transformation (HT), and we examined whether leukoaraiosis (LA) was associated with HT in these cases. We prospectively enrolled 251 patients who were admitted to two hospitals within one month of experiencing cardioembolic stroke due to AF/RHD. LA severity was assessed using three visual rating scales. HT was identified in 99 patients (39.4%) based on baseline computed tomography (CT) and post-admission magnetic resonance imaging or second CT...
