PURPOSE This study aims to assess the phase relationship of prefrontal tissue oxyhemoglobin oscillations using wavelet phase coherence analysis of cerebral Delta [HbO₂] signals in cerebral infarction (CI) patients during the resting state. METHODS Continuous recordings of near-infrared spectroscopy signals were obtained from the left and right prefrontal lobes in 21 subjects with CI (Group CI...

BACKGROUND Matrix metalloproteinase 10 (MMP10) plays an important role in ischemic stroke and has a close relationship with some stroke risk factors. The aim of this study was to investigate the relationship between two single nucleotide polymorphisms (SNP) in the exon regions of the MMP10 gene and atherothrombotic cerebral infarction risk. METHODS Five hundred and thirty-seven hospital-based...

BACKGROUND AND PURPOSE Delayed cerebral ischemia is a significant cause of morbidity and mortality after aneurysmal SAH, leading to poor outcomes. The purpose of this study was to evaluate the usefulness of CTP in determining delayed cerebral ischemia in patients with aneurysmal SAH. MATERIALS AND METHODS We conducted a systematic review evaluating studies that assessed CTP in patients with a...

The validity of a clinical classification system was assessed for subtypes of cerebral infarction for use in clinical trials of putative stroke therapies and clinical decision making in a population based stroke register (n = 536) compiled in Perth, Western Australia in 1989-90. The Perth Community Stroke Project (PCSS) used definitions and methodology similar to the Oxfordshire Community Strok...

Rapid and targeted diagnostic evaluation is essential in the clinical diagnosis of cerebral ischaemic infarction. According to the principle “time is brain”, clinical evaluation should be performed as a matter of urgency to initiate potential treatment without any delay. Cerebral infarction is a medical emergency and accordingly, patients with suspected cerebral infarction have priority in the ...

AIMS To determine the prevalence of unilateral neonatal cerebral infarction in infants born at 32 weeks gestation and above; to describe the clinical course, imaging results, and outcome of neonatal cerebral infarction; and to investigate possible aetiology. METHODS Twelve cases of unilateral neonatal cerebral infarction were identified from neonatal unit records for the years 1987-93. Each c...

Cerebral infarction is a severe hypoxic ischemic necrosis with accelerated neuronal cell apoptosis in the brain. As a monoclonal antibody against interleukin 6, tocilizumab (TCZ) is widely used in immune diseases, whose function in cerebral infarction has not been studied. This study aims to reveal the role of TCZ in regulating neuronal cell apoptosis in cerebral infarction. The cerebral infarc...

BACKGROUND AND PURPOSE Methods have not been well developed and tested to predict the extent of remote degeneration in the central nervous system that follows cerebral infarction. We hypothesized that the extent of infarction overlap with the cerebral hemispheric course of the corticospinal tract (CST) on structural MR imaging predicts the extent of ipsilateral cerebral peduncular atrophy in pa...

BACKGROUND Thrombus migration (TM) in intracranial vessels during ischemic stroke has been reported in the form of case reports, but its incidence, impact on the technical success of subsequent endovascular thrombectomy and patients' outcome have never been studied systematically. METHODS AND RESULTS Retrospective analysis was done of 409 patients with isolated middle cerebral artery occlusio...

BACKGROUND AND PURPOSE The clinical patterns of stroke and the angiographic distribution of cerebral atherosclerosis in Chinese people are different from those in whites. Studies relating carotid atherosclerosis and vascular risk factors to various types of stroke in Chinese people are lacking. METHODS Based on clinical information, we separated 367 stroke patients living in Taiwan into four ...
