BACKGROUND: Cerebral small vessel disease (SVD) is associated with increased risk of cerebral infarction and hemorrhage. Obstructive sleep apnea (OSA) is known to increase the risk of cerebrovascular disease. This study aimed to investigate the association between cerebral SVD and severity of OSA. METHODS: A total of 170 patients were included from the patient registry at the present Sleep Center; these patients underwent both magnetic resonance imaging (MRI) of the brain and polysomnography (PSG) for suspected OSA...

Sickle cell disease is a common and life-threatening haematological disorder that affects millions of people worldwide. Abnormal sickle-shaped erythrocytes disrupt blood flow in small vessels, and this vaso-occlusion leads to distal tissue ischaemia and inflammation, with symptoms defining the acute painful sickle-cell crisis. Repeated sickling and ongoing haemolytic anaemia, even when subclinical, lead to parenchymal injury and chronic organ damage, causing substantial morbidity and early mortality. Currently available treatments are limited to transfusions and hydroxycarbamide, although stem cell transplantation might be a potentially curative therapy...

The consequences of cerebrovascular disease are among the leading health issues worldwide. Large and small cerebral vessel disease can trigger stroke and contribute to the vascular component of other forms of neurological dysfunction and degeneration. Both forms of vascular disease are driven by diverse risk factors, with hypertension as the leading contributor. Despite the importance of neurovascular disease and subsequent injury after ischemic events, fundamental knowledge in these areas lag behind our current understanding of neuroprotection and vascular biology in general...

BACKGROUND: Increased level of blood viscosity, which is one of the major factors that determine blood rheology, has been reported as a risk factor or predictor for cerebrovascular events. We investigated how blood viscosity is associated with acute stroke and chronic radiological manifestations of cerebral small vessel disease, and how blood viscosity changes after stroke. METHODS: We prospectively enrolled consecutive patients with acute ischemic stroke. Whole blood viscosities at a low or high shear rate were measured using a scanning capillary tube viscometer, and were referred to as diastolic blood viscosity (DBV) and systolic blood viscosity (SBV), respectively...

Current image processing techniques capture large vessels reliably but often fail to preserve connectivity in bifurcations and small vessels. Imaging artifacts and noise can create gaps and discontinuity of intensity that hinders segmentation of vascular trees. However, topological analysis of vascular trees require proper connectivity without gaps, loops or dangling segments. Proper tree connectivity is also important for high quality rendering of surface meshes for scientific visualization or 3D printing...

BACKGROUND AND PURPOSE: Chronic infections and cardiac dysfunction are risk factors for stroke. We hypothesized that blood biomarkers of infection (procalcitonin) and cardiac dysfunction (midregional proatrial natriuretic peptide [MR-proANP]), previously associated with small vessel stroke and cardioembolic stroke are also associated with subclinical cerebrovascular damage, including silent brain infarcts and white matter hyperintensity volume. METHODS: The NOMAS (Northern Manhattan Study) was designed to assess risk factors for incident vascular disease in a multiethnic cohort...

BACKGROUND: The presences of white matter hyperintensity (WMH) and lacunar infarct are recognized as risk factors of dementia, stroke, and mortality. It is undetermined whether visceral adipose tissue (VAT) area is associated with an increased risk of cerebral small vessel disease. We explored whether VAT area was responsible for cerebral small vessel disease through the identification of WMH and lacunar infarct. SUBJECTS: A total of 2046 subjects free of cerebrovascular disease who underwent brain magnetic resonance imaging (MRI) and abdominal fat computed tomography (CT) during a general health check-up were enrolled...

Over the past few decades, vascular flow-dependent imaging techniques have proven to be effective for the visualization of large vessel diseases. However, these approaches are unlikely to be efficacious for small vessels because the affected small vessels cannot always be visualized directly, owing to a lack of detection sensitivity. Recently, many researchers have introduced state-of-the-art imaging techniques to visualize cerebral microvessels using ultra-high-field (UHF) magnetic resonance angiography (MRA)...

Progressive neurovasculopathy in children with sickle cell disease (SCD) results in decreased cognitive function and quality of life (QoL). Hematopoietic cell transplantation (HCT) is believed to halt progression of neurovasculopathy. Quantitative analysis of T2-weighted fluid attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) for white matter hyperintensity (WMH) burden provides a meaningful estimate of small vessel cerebrovascular disease. We asked if quantitative analysis of WMH could complement standardized clinical assessment of MRI/magnetic resonance angiography (MRA) for assessing SCD central nervous system vasculopathy before and after HCT...

BACKGROUND: Although 20-30% of all strokes occur in the posterior circulation, few studies have explored the characteristics of patients with strokes in the posterior compared to the anterior circulation so far. Especially data on young patients is missing. METHODS: In this secondary analysis of data of the prospective multi-centre European sifap1 study that investigated stroke and transient ischemic attack (TIA) patients aged 18-55 years, we compared vascular risk factors, stroke aetiology, presence of white matter hyperintensities (WMH) and cerebral microbleeds (CMB) between patients with ischaemic posterior circulation stroke (PCS) and those having suffered from anterior circulation stroke (ACS) based on cerebral MRI...

OBJECTIVES: Large prospective studies have established that sleep-disordered breathing (SDB) is associated with an increased incidence of cardiovascular and cerebrovascular diseases. Heterogeneous results have been published about SDB and ischaemic stroke mechanism. The aim of this study was to evaluate the relationship between poststroke apneic syndrome and stroke aetiologies according to the ASCO classification. METHODS: A total of 134 patients with acute ischaemic cerebrovascular events were prospectively included...

A 68-year-old female patient was admitted in our clinic with severe frontal bilateral headache, dizziness, depression and cognitive decline in the context of a previously diagnosed acromegaly. She also had high blood pressure, dyslipidemia, secondary diabetes mellitus. Acromegaly was caused by a growth hormone (GH) secreting-pituitary macroadenoma, so a transsphenoidal surgery was performed. The postoperative magnetic resonance imaging (MRI) scan revealed a 20÷22÷25 mm pituitary mass remnant and medical therapy with somatostatin analogues (SSAs) was started...

BACKGROUND: Microbleeds (MBs) are observed frequently in Alzheimer's disease (AD) and suggested to play a crucial role in the pathophysiology, but their clinical significance remains unclear. MATERIALS AND METHODS: The study recruited 100 patients with AD who were diagnosed at the memory clinic in Seoul Medical Center in 2014. For each patient, baseline characteristics, neuropsychological tests, cerebrovascular risk factors, medial temporal lobe atrophy (MTLA), and severity of small vessel disease (SVD) according to the existence of MBs were evaluated...

OBJECTIVE: To study the association of N-terminal pro-brain natriuretic peptide (NT-proBNP) with several brain MRI markers of brain vascular disease in a sample of participants free of stroke and dementia. METHODS: NT-proBNP plasma level was determined by means of a sandwich immunoassay method in a cohort study comprising 278 hypertensive patients. The presence of silent brain infarcts, brain microbleeds, enlarged perivascular spaces, and white matter hyperintensity volumes was assessed by brain MRI...

Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder and cause of dementia and is characterized by amyloid plaques and neurofibrillary tangles. AD has traditionally been considered to primarily affect gray matter, but multiple lines of evidence also indicate white matter (WM) pathology and associated small-vessel cerebrovascular disease. WM glucose delivery and metabolism may have implications for local tissue integrity, and [(18)F]-fluorodeoxyglucose positron emission tomography (FDG-PET) may be helpful to assess neuroglial and axonal function in WM...
