BACKGROUND: Hypoxic but viable neural tissue is seen on 1-(2-18F-fluoro-1-[hydroxymethyl]ethoxy) methyl-2-nitroimidazole (18F-FRP170) positron emission tomography (PET) in patients with chronic cerebral ischemia with a combination of misery perfusion and moderately reduced oxygen metabolism. Cognitive function sometimes improves after revascularization surgery in patients with chronic cerebral ischemia. OBJECTIVES: We used brain perfusion single-photon emission computed tomography (SPECT) and 18F-FRP170 PET to determine whether hypoxic tissue was reduced following the restoration of cerebral perfusion after carotid endarterectomy (CEA) in patients with severe stenosis of the cervical internal carotid artery (ICA) and whether the reduction in hypoxic tissue was associated with cognitive improvement...

BACKGROUND: Cerebrovascular disease is an important cause of cognitive impairment. The aim of this study is to report the relationship between cognitive function and risk factors at baseline and during follow-up in the Stenting and Aggressive Medical Management for Preventing Recurrent stroke in Intracranial Stenosis (SAMMPRIS) trial. METHODS: Subjects in the SAMMPRIS trial were included in this study. In order to have an assessment of cognitive function independent of stroke, patients with a stroke as a qualifying event whose deficits included aphasia or neglect were excluded from these analyses as were those with a cerebrovascular event during follow-up...

BACKGROUND: The natural history of vertebrobasilar artery (VBA) stenosis or occlusion remains understudied. METHODS: Patients with diagnosis of ischemic stroke or transient ischemic attack (TIA) who were noted to have VBA stenosis based on computed tomography or magnetic resonance imaging or catheter-based angiogram were selected from Taiwan Stroke Registry. Cox proportional hazards model was used to determine the hazards ratio (HR) of recurrent stroke and death within 1 year of index event in various groups based on severity of VBA stenosis (none to mild: 0-49%; moderate to severe: 50-99%: occlusion: 100%) after adjusting for differences in demographic and clinical characteristics between groups at baseline evaluation...

BACKGROUND: Aortic complicated lesions (ACLs) are key parameters for evaluating aortic embolic sources in embolic stroke, and are usually diagnosed using transesophageal echocardiography (TEE). However, alternative methods for diagnosing ACLs have not been well established. We investigated associations between high-intensity areas on T1-weighted imaging (T1WI) with magnetization-prepared rapid acquisition with gradient echo (MPRAGE) and ACLs on TEE among ischemic stroke patients. METHODS: Participants comprised 135 patients (mean age, 71 years; 35 women) with ischemic stroke or transient ischemic attack who underwent TEE for evaluation of embolic sources and plaque imaging using MPRAGE for evaluation of aortic or carotid plaques...

BACKGROUND: While returning to paid work is a crucial marker of stroke recovery, little is known about the differences in unpaid work by sex following stroke. We aimed to determine the sex differences in participation in unpaid work 12 months after stroke. METHODS: Psychosocial outcomes in stroke were a prospective, multicentre observational study that recruited individuals, 18-64 years, within 28 days of stroke from New South Wales, Australia. Unpaid work was defined as ≥5 h per week of one or more of: unpaid domestic work for the household; unpaid care of others; looking after own children without pay or looking after someone else's children without pay...

BACKGROUND: Blood pressure variability (BPV) is associated with target organ damage progression and increased cardiovascular events, including stroke. The aim of this study was to evaluate the associations between short-term BPV during acute periods and recanalization degree, early neurological deterioration (END) occurrence, and functional outcomes in acute ischemic stroke patients who had undergone intra-arterial thrombectomy (IAT). METHODS: We retrospectively analyzed 303 patients with large vessel occlusive stroke who underwent IAT...

BACKGROUND: The association that exists between livedo reticularis (LR) and stroke is known as Sneddon's syndrome (SnS). The disorder is classified as primary SnS (PSnS), if the cause remains unknown and secondary SnS. The condition is rare and it occurs mainly sporadically. In 2014, 2 independent teams described a new genetic disorder with childhood-onset, which was called deficiency of adenosine deaminase 2 (DADA2), characterized by recurrent fevers and vascular pathologic features that included LR and stroke...

BACKGROUND: There are limited epidemiologic data on cerebral venous sinus thrombosis (CVST). We aim to summarize baseline characteristics and outcomes using a large nationally representative administrative database. METHODS: Using the 2013 Nationwide Readmissions Database, we used validated International Classification of Disease, Ninth Revision codes to identify baseline characteristics of patients admitted with CVST. We calculated readmission rates (per 100,000 index hospitalizations) for neurological complications...

BACKGROUND: Recently, finger-like projections (FLP) and subarachnoid haemorrhage extension (SAHE) of lobar intracerebral haemorrhage (LH) on acute CT together with ApoE4 genotype have been used in a prediction model for histopathologically proven cerebral amyloid angiopathy (CAA). Our aim was to analyse FLP and SAHE on acute/early subacute magnetic resonance imaging (MRI) and to assess the association with probable CAA diagnosis according to modified Boston criteria. METHODS: We retrospectively studied MRI scans (and CT if available) performed <7 days in a cohort of consecutive acute LH patients >55 years...

INTRODUCTION: Serotonin affects several brain functions including cognition. The serotonin transporter (SERT) regulates brain serotonin levels through reuptake into neurons. The gene encoding this transporter, the SERT gene, has several functional polymorphisms affecting the number of transporters and thereby the serotonin levels. SERT gene expression may be important for cognition and selective serotonin reuptake inhibitors (SSRI) may improve cognition post stroke. We therefore examined the association between SERT genotypes, cognitive function and early treatment with the SSRI citalopram among non-depressed Caucasian stroke patients...

OBJECTIVES: Endovascular treatment (EVT) has emerged as the gold standard therapy for stroke due to large vessel occlusion (LVO). There is however limited evidence to suggest that similar efficacy can be expected in elderly patients. We aimed to assess the efficacy and safety of EVT in elderly patients (aged > 80), comparing outcomes to younger patients (aged < 80). MATERIAL AND METHODS: A total of 195 patients with LVO stroke treated with EVT were included and dichotomized by age...

BACKGROUND: Noncontrast three-dimensional time-of-flight magnetic resonance angiography (3D TOF MRA) is commonly used to examine intracranial arterial stenosis, although it can be difficult to identify the etiology of the stenosis. Our aim was to determine the effectiveness of 3D TOF MRA in differentiating an intracranial arterial dissection from atherosclerosis. METHODS: During 2015-2017, 356 patients had confirmed intracranial arterial stenosis based on high resolution-magnetic resonance imaging...

BACKGROUND: Early neurological deterioration (END) following acute stroke is associated with poorer long-term outcomes. Identification of patients at risk could assist early monitoring and treatment decisions. This review summarised the evidence describing non-radiological biomarkers for END. SUMMARY: Electronic searches from January 1990 to March 2017 identified studies reporting a blood/cerebrospinal fluid (CSF)/urine biomarker measurement within 24 h of acute stroke and at least 2 serial assessments of clinical neurological status (< 24 h and < 7 days)...
