Title:Basal Ganglia Enlarged Perivascular Spaces are Linked to Cognitive Function in Patients with Cerebral Small Vessel Disease. VOLUME: 11 ISSUE: 2. Author(s):Marjolein Huijts, Annelien Duits, Julie Staals, Abraham A Kroon, Peter W de Leeuw and Robert J van Oostenbrugge. Affiliation:Department of Neurology, Maastricht University Medical Centre, PO Box 5800, 6202 AZ Maastricht , The Netherlands.. Keywords:Cerebral small vessel disease, cognition, enlarged perivascular spaces, hypertension, lacunar stroke, white matter lesions.. Abstract:Enlarged perivascular spaces (EPVS) are a feature of cerebral small vessel disease (cSVD) and have been related to cSVD severity. A higher number of EPVS were related to decreased cognition in healthy elderly, but this has never been investigated in patients at high risk of cSVD. We included 189 patients with a high risk of cSVD (hypertensive patients and lacunar stroke patients). Patients underwent brain MRI and extensive neuropsychological assessment. EPVS ...
Cerebral small vessel disease is considered hereditary in about 5% of patients and is characterized by lacunar infarcts and white matter hyperintensities on MRI. Several monogenic hereditary diseases causing cerebral small vessel disease and stroke have been identified. The purpose of this systematic review is to provide a guide for determining when to consider molecular genetic testing in patients presenting with small vessel disease and stroke. CADASIL, CARASIL, collagen type IV mutations (including PADMAL), retinal vasculopathy with cerebral leukodystrophy, Fabry disease, hereditary cerebral hemorrhage with amyloidosis, and forkhead box C1 mutations are described in terms of genetics, pathology, clinical manifestation, imaging, and diagnosis. These monogenic disorders are often characterized by early-age stroke, but also by migraine, mood disturbances, vascular dementia and often gait disturbances. Some also present with extra-cerebral manifestations such as microangiopathy of the eyes and ...
OBJECTIVES: We hypothesized that common variants in the collagen genes COL4A1/COL4A2 are associated with sporadic forms of cerebral small vessel disease. METHODS: We conducted meta-analyses of existing genotype data among individuals of European ancestry to determine associations of 1,070 common single nucleotide polymorphisms (SNPs) in the COL4A1/COL4A2 genomic region with the following: intracerebral hemorrhage and its subtypes (deep, lobar) (1,545 cases, 1,485 controls); ischemic stroke and its subtypes (cardioembolic, large vessel disease, lacunar) (12,389 cases, 62,004 controls); and white matter hyperintensities (2,733 individuals with ischemic stroke and 9,361 from population-based cohorts with brain MRI data). We calculated a statistical significance threshold that accounted for multiple testing and linkage disequilibrium between SNPs (p | 0.000084). RESULTS: Three intronic SNPs in COL4A2 were significantly associated with deep intracerebral hemorrhage (lead SNP odds ratio [OR] 1.29, 95%
© Cambridge University Press 2014. Introduction: Cerebral ischemia is thought to be an important disease mechanism in cerebral small vessel disease (SVD). It has been hypothesized that acute ischemia in the territory of the perforating artery results in lacunar stroke, while chronic ischemia occurring in the distal territories of the perforating arteries results in changes to cerebral white-matter, known as leukoaraiosis. The spatial pattern of leukoaraiosis, with changes first occurring in the brain regions furthest from the origin of the perforating arteries, would be consistent with disease occurring due to hypoperfusion. This has led to the suggestion that cerebral blood flow (CBF) is reduced in SVD, and many studies have been performed to investigate this issue. In addition, cerebral arteriopathy underlying SVD may also impair the ability of small cerebral vessels to vasodilate, leading to problems maintaining perfusion in response to drops in blood pressure and perfusion pressure. Impairments of
Obkective: Fibrinogen levels and fibrinogen clot structure have been implicated in pathogenesis of vascular disease. We examined fibrinogen levels and variation in fibrinogen genes (fibrinogen γ (FGG), α (FGA) and β (FGB)), associated with fibrin clot structure and fibrinogen levels, in relation to cerebral small vessel disease (SVD). Methods and Results This study was performed in the Rotterdam Scan Study, a population-based study among 1077 elderly with cerebral magnetic resonance imaging. Plasma fibrinogen levels and haplotypes were determined. We examined the association of fibrinogen levels and haplotypes with silent brain infarcts and white matter lesions by means of logistic regression models. We constructed seven haplotypes (frequency ,0.01) that describe the total common variation in the FGG and FGA genes. Haplotype 2 (G-A-T-A-G-T-G) was associated with presence of silent brain infarcts when compared to the most frequent haplotype (G-G-T-G-G-T-A) (odds ratio (OR) 1.41, 95% CI ...
Cerebral small vessel disease (SVD) is an important cause of vascular cognitive impairment. Recent studies have demonstrated that structural connectivity of brain networks in SVD is disrupted. However, little is known about the extent and location of the reduced connectivity in SVD. Here they invest …

I am a Stroke Association Post-Doctoral Fellow and part time research radiographer at Edinburgh Imaging. My research interests include chronic systemic inflammatory arthropathies and their effects on the brain, and cerebral small vessel disease. My post doc focuses on the morphological changes in retinal vessels and retinal nerve fibre layers and relationships to cerebral small vessel disease.. My PhD investigated the role of inflammation in cerebral small vessel disease (SVD), work conducted under supervision of Professors Joanna Wardlaw (stroke; neuroimaging) and Stuart Ralston (rheumatology). My PhD was cross-disciplinary as we were interested in inflammatory arthropathies and effects on the brain. I found, for the first time, an increased burden of enlarged perivascular spaces (PVS) as a marker of inflammation in a group of patients with systemic lupus erythematosus, a chronic inflammatory disease, versus healthy controls and stroke patients with overt SVD, suggesting that inflammation is ...

Cerebral small vessel disease (CSVD) is a common group of neurological conditions that confer a significant burden of morbidity and mortality worldwide. In most cases, CSVD is only recognized in its advanced stages once its symptomatic sequelae develop. However, its significance in asymptomatic healthy populations remains poorly defined. In population-based studies of presumed healthy elderly individuals, CSVD neuroimaging markers including white matter hyperintensities, lacunes, cerebral microbleeds, enlarged perivascular spaces, cortical superficial siderosis, and cerebral microinfarcts are frequently detected. While the presence of these imaging markers may reflect unique mechanisms at play, there are likely shared pathways underlying CSVD. Herein, we aim to assess the etiology and significance of these individual biomarkers by focusing in asymptomatic populations at an epidemiological level. By primarily examining population-based studies, we explore the risk factors that are involved in the ...

Cognitive impairment is common in patients with cerebral small vessel disease, but is not well detected using common cognitive screening tests which have been primarily devised for cortical dementias. We developed the Brief Memory and Executive Test (BMET); a rapid screening measure sensitive to the impaired executive function and processing speed characteristic of small vessel disease (SVD). To assess the BMETs validity for general use, we evaluated it when administered by non-psychologists in a multicentre study and collected control data to derive normative scores. Two-hundred participants with SVD, defined as a clinical lacunar stroke and a corresponding lacunar infarct on MRI, and 303 healthy controls aged between 40-90 years old were recruited. The BMET, as well as the Montreal Cognitive Assessment (MoCA) and Mini Mental State Examination (MMSE), were performed. Overall, 55 SVD participants underwent repeat testing at 3 months to assess the BMET test-retest reliability. Administering the BMET
Results: We enrolled 612 ICH survivors, and followed them for a median of 46.3 months (Inter-Quartile Range: 35.5-58.7). A total of 214/612 (35%) participants developed dementia. Higher global CSVD scores at baseline were associated with faster cognitive decline (Coeff -0.25, Standard Error [SE] 0.02) and dementia risk (Sub-Hazard Ratio 1.35, 95% CI 1.10-1.65). The global score outperformed the CAA and HTNA scores in predicting post-ICH dementia (all p,0.05). Compared to a model including readily available clinical and CT data, inclusion of the global CSVD score resulted in improved prediction of post-ICH dementia (Area Under the Curve [AUC] 0.89, SE 0.02 vs. AUC 0.81, SE 0.03, p = 0.008 for comparison). Global CSVD scores ≥ 2 had highest sensitivity (83%) and specificity (91%) for dementia diagnosis. ...

Here, we demonstrated that endothelial dysfunction is an early precipitant of disease development in a rat model of SVD and a sample of humans with sporadic SVD. We identified a deletion in Atp11b and loss of ATP11B protein that cause endothelial dysfunction, with abnormalities of the BBB TJs, increased EC proliferation, and reduction in eNOS and NO. This dysfunction led to secretion of factors, including HSP90α, which blocked the maturation of OPCs into myelinating oligodendrocytes, consistent with the impairment of myelination and inherent vulnerability of white matter to damage seen in adult humans with SVD (42). We also demonstrated therapeutic reversal of endothelial dysfunction and associated reduction in white matter vulnerability. The early reduction of the BBB TJ markers but lack of tracer leakage (along with the brain slice culture experiments) showed that leakage of substances through the BBB is not important for initial SVD pathology in our model. However, it is highly likely that ...
Scans of sufficient quality for data analysis were available in 29 cases and 35 controls. NAA was significantly reduced in patients compared with controls (lower by 7.27%, P = 0.004). However, when lesion load within each individual voxel (mean 22% in SVD vs 5% in controls, P , 0.001) was added as a covariate, these differences were no longer significant, suggesting that the metabolite differences arose primarily from differences in lesioned tissue. In patients with SVD, there was no correlation between cognitive scores and any brain metabolite. No lactate, an indicator of anaerobic metabolism, was detected. ...

Stroke and dementia are common and debilitating health issues worldwide. Cerebral small vessel disease (SVD) underlies a large proportion of these cases. However, the cause of SVD is unknown. Research into the causes and pathophysiological mechanisms of SVD is hampered by the fact that small vessels themselves are difficult to visualise in people. The wide range of clinical
The connection between COPD and cerebral small vessel disease was suggested by two earlier studies, but the connection between COPD and cerebral microbleeds, the location of which can help elucidate underlying disease mechanisms, has not been studied, said researchers Lies Lahousse, PhD, of the Department of Respiratory Medicine at Ghent University Hospital in Belgium and Bruno Stricker, PhD, of the Department of Epidemiology at Erasmus Medical Center in Rotterdam, the Netherlands. In the current study, we found, for the first time, that COPD increases the risk of cerebral microbleeds in deep or infratentorial brain regions, not only in a cross-sectional analysis but also in a longitudinal analysis in subjects without microbleeds at baseline.. Microbleeds in deep (deep gray matter of the basal ganglia and thalamus and white matter of the corpus callosum, internal, external, and extreme capsule) or infratentorial (brainstem and cerebellum) locations are suggestive of hypertensive or ...
Pulmonary hypertension is a significant cause of morbidity and mortality. Unfortunately, non-specific presentation and lack of awareness of the disease frequently lead to significant delay in diagnosis, often with the onset of right heart failure, when prognosis is poor and therapy is of limited effectiveness. The classification of pulmonary hypertension is a clinical one grouping diseases into categories with similar patho-physiological mechanism and therapeutic options. Pulmonary biopsy can provide a definitive diagnosis but is hazardous in patients with pulmonary hypertension. Imaging has emerged as an invaluable tool in differentiating the aetiology, assessing disease severity and directing further management. One of the most important roles of imaging is to differentiate diseases resulting from obstruction of the large pulmonary arteries from those secondary to diffuse small vessel disease, as these have very different prognosis and are also treated differently. Small vessel diseases ...

Cerebrovascular disease is currently the second most common cause of death after ischemic heart disease. In this article, we mainly focus on the application of permeability imaging in cases of ischemic and hemorrhagic stroke, and cerebral small vessel disease. In this review, we discuss the application of permeability imaging in ischemic stroke from two aspects: 1) for the prediction of hemorrhagic transformation after infarction, and 2) for the evaluation of newborn secondary and tertiary collateral circulations. Quantitative measurements of blood-brain barrier (BBB) disruption by the Dynamic Contrast Enhance MR (DCE-MR) can reveal the severity of intracranial hemorrhage (ICH)-induced brain damage, and that the technique has the potential to be used for testing the efficacy of interventions aimed at reducing tissue damage around the hematoma. Currently, DCE-MR is mostly applied for the assessment of tumors in patients. There is less research focused on the evaluation of mild BBB defects in normal or

Cardiac magnetic resonance imaging (CMR) with adenosine-stress myocardial perfusion is gaining importance for the detection and quantification of coronary artery disease (CAD). However, there is little knowledge about patients with CMR-detected ischemia, but having no relevant stenosis as seen on coronary angiography (CA). The aims of our study were to characterize these patients by CMR and CA and evaluate correlations and potential reasons for the ischemic findings. 73 patients with an indication for CA were first scanned on a 1.5T whole-body CMR-scanner including adenosine-stress first-pass perfusion. The images were analyzed by two independent investigators for myocardial perfusion which was classified as subendocardial ischemia (n = 22), no perfusion deficit (n = 27, control 1), or more than subendocardial ischemia (n = 24, control 2). All patients underwent CA, and a highly significant correlation between the classification of CMR perfusion deficit and the degree of coronary luminal ...

Treatment options for patients with advanced HCC increased by sorafenib, and long-term survival for patients with advanced stage HCC has become possible to some extent. However, development of a more potent fi rst-line novel molecular targeted agent replacing sorafenib and a potent second-line agent after disease progression on or intolerant to sorafenib has been warranted because sorafenib lacks tumor shrinking/necrotizing effects and induces relatively severe adverse events such as hand foot skin reaction. Many agents in the 1st line and 2nd line setting were attempted to develop between 2007 and 2016, but all of these clinical trials failed. On the other hand, clinical trials of 4 agents (regorafenib, lenvatinib, cabozantinib, and ramucirumab) succeeded in succession in ...

We know that sleep apnea can seriously affect the heart (right-sided failure) and brain (increased risk of small vessel disease and mini strokes). But why the eyes? Some investigators feel the cause is mechanical stress--i.e. smashing and stretching the eye against pillow--which is supported by the fact that one-sided sleepers often get one-sided F.E.S. Others wonder if alternating ischemia (not enough oxygenated blood) followed by reperfusion (flood of oxygen-rich blood when the apnea ceases) results in tissue inflammation. Studies of floppy lids (what happened to the sleeper upon which these lids resided!?!) showed an inflammatory injury reaction consistent with both stress and ischemia as seen in other tissue types ...
Tough problem. I cant make recommendations, but diffuse small vessel disease can be tough to manage. Stents and bypasses to the heart need a minimum diameter and only work with discrete blockages not a narrowing of an entire vessel. Treatment often involves anti-platelets (aspirin etc) aggressive diabetes control, cholesterol control, diet, weight loss. Talk with your doctor maybe second opinion if not happy ...

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. 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. Correlations between blood viscosity and acute stroke etiology or chronic radiological manifestations of cerebral small vessel disease were investigated. The temporal profiles of blood viscosity at the onset of stroke and follow-up at 1 and 5 weeks were investigated. Of the 127 patients admitted with acute ischemic stroke, 63 patients were included in the

N2 - Small vessel diseases (SVDs) of the brain are likely to become increasingly common in tandem with the rise in the aging population. In recent years, neuroimaging and pathological studies have informed on the pathogenesis of sporadic SVD and several single gene (monogenic) disorders predisposing to subcortical strokes and diffuse white matter disease. However, one of the limitations toward studying SVD lies in the lack of consistent assessment criteria and lesion burden for both clinical and pathological measures. Arteriolosclerosis and diffuse white matter changes are the hallmark features of both sporadic and hereditary SVDs. The pathogenesis of the arteriopathy is the key to understanding the ...

Stroke is an important risk factor for dementia. Epidemiological studies have indicated a high incidence of dementia in stroke patients. There is currently no effective biomarker for the diagnosis of post-stroke dementia (PSD). D-amino acid oxidase (DAO) is a flavin-dependent enzyme widely distributed in the central nervous system. DAO oxidizes D-amino acids, a process which generates neurotoxic hydrogen peroxide and leads to neurodegeneration. This study aimed to examine post-stroke plasma DAO levels as a biomarker for PSD. In total, 53 patients with PSD, 20 post-stroke patients without dementia (PSNoD), and 71 age- and gender-matched normal controls were recruited. Cognitive function was evaluated at more than 30 days post-stroke. Plasma DAO was measured using the enzyme-linked immunosorbent assay. White matter hyperintensity (WMH), a neuroimaging biomarker of cerebral small vessel diseases, was determined by magnetic resonance imaging. We found that plasma DAO levels were independently higher in PSD

Although several pathogenic mechanisms including an unbalance between production and clearance of amyloid beta (Aβ) protein as well as the prion hypothesis have been invoked as possible disease triggers, they do not explain completely the disease pathogenesis. This incomplete disease knowledge ...

Results: A total of 212 patients, mean age (±SD) 69.5 years (±16.1), 102 (48%) male, had available MR before IV thrombolysis. Evidence of BBB leakage was present in 175 (80%) and 205 (94%) patients in the ischemic and nonischemic area, respectively. Lacunar infarcts (β = 0.17, p = 0.042) were associated with BBB leakage in the ischemic area, and brain atrophy was associated with BBB leakage in both ischemic (β = 0.20, p = 0.026) and nonischemic (β = 0.27, p = 0.001) areas. Increasing SVD grade was independently associated with BBB leakage in both ischemic (β = 0.26, p = 0.007) and nonischemic (β = 0.27, p = 0.003) area. ...

The patient had a very poor response to aggressive medical and surgical approaches. The clinical improvement with 20 hyperbaric oxygen sessions @ 2.0 ATA for 90 minutes each, was dramatic. She had decreased swelling (edema), no pain or bleeding and was able to wear shoes and resume activities of daily living such as shopping. After 40 sessions the wounds were completely healed and the overall functional skills of the patient improved significantly.. ...
INTRODUCTION: White matter hyperintensities (WMHs) are areas of abnormal signal on magnetic resonance images (MRIs) that characterize various types of histopathological lesions. The load and location of WMHs are important clinical measures that may indicate the presence of small vessel disease in aging and Alzheimers disease (AD) patients. Manually segmenting WMHs is time consuming and prone to inter-rater and intra-rater variabilities. Automated tools that can accurately and robustly detect these lesions can be used to measure the vascular burden in individuals with AD or the elderly population in general. Many WMH segmentation techniques use a classifier in combination with a set of intensity and location features to segment WMHs, however, the optimal choice of classifier is unknown. METHODS: We compare 10 different linear and nonlinear classification techniques to identify WMHs from MRI data. Each classifier is trained and optimized based on a set of features obtained from co-registered MR ...
The term cognition describes the human brains ability to learn, think, and process information. For a normal daily life to be possible, cognitive functions must be intact. Impairment of cognitive functions results in difficulties in coping with both complex and everyday activities, such as daily planning, meeting the demands of work life, managing finances, preparing food, keeping order, socializing, or cultivating interests. Impaired cognitive functions also lead to an increased sensitivity to stress.. There are several disorders and medical procedures that show cognitive impairment as an important - though not always identified - manifestation, such as affective disorders, schizophrenia, abuse, neurological motor disorders, MS, traumatic brain injury, cancer, infections, vascular disease (ischemic heart disorder, heart failure, hypertension, diabetes mellitus, stroke, small vessel disease), coronary by-pass surgery, and other major surgical procedures. Multimorbidity relatively often result ...
The Special Course which typically launches the annual AANP meeting was anything but typical this year. Rather than the usual series of research presentations which has characterized the first day of the meeting, the 2015 edition of the Special Course focused on need-to-know practical topics. Dr. Beatriz Lopes put together a program that offered something for everyone -- from trainee to seasoned practitioner. The morning started with a presentation by Dr. Caterina Giannini on primary CNS lymphoma, as well as its mimickers and precursors. Far from being a straightforward diagnosis, lymphoma -- particularly in the setting of corticosteroid therapy -- can be mistaken for anything from multiple sclerosis to infarct. Next, two eminent scholars from Paris, Drs. Francoise Gray and Elisabeth Tournier-Lasserve, presented a three-part lecture on the hereditary non-amyloid small vessel diseases of the brain. Then Charles Eberhart showed up from Johns Hopkins to provide a primer on ophthalmic pathology, ...

Bob,. Tks for sharing that article with us. Alot of people are still using these medicines in their daily treatment plan with good results, but there are some that hopefully their doctors are weighing the odds of this treatment.. I wonder, if in this study that was conducted, if these patients were checked for undetected underlying causes that could have caused the their negative reactions like, heart disease, lung conditions and in my case, small vessel disease that wasnt detected in me until I had a minor stroke.. Of course we all know that all medicines have risks and the drug companies have to list every possible reaction or interaction. This can be scarey to anyone that reads all this information, but in most cases the serious reactions are rare.. Hopefully patients are being more proactive in their care and questioning all aspects of treatment with their doctors before starting anything new.. Tks again, Babs. ...

A new report estimates that nearly half of all U.S. adults have some form of heart or blood vessel disease, a medical milestone thats mostly due to recent guidelines that expanded how many people have high blood pressure. The American Heart Association said today that more than 121 million adults had cardiovascular disease in 2016. Taking out those with only high blood pressure leaves 24 million, or 9 percent of adults, who have other forms of disease such as heart failure or clogged arteries.. Measuring the burden of diseases shows areas that need to improve, the heart associations chief science and medical officer, Dr. Mariell Jessup, said in a statement.. High blood pressure, which had long been defined as a top reading of at least 140 or a bottom one of 90, dropped to 130 over 80 under guidelines adopted in 2017. It raises the risk for heart attacks, strokes and many other problems, and only about half of those with the condition have it under control.. Being diagnosed with high blood ...
