Sporadic cerebral small vessel disease (cSVD) is primarily attributed to heritability and vascular risk factors. Still, our understanding of the causative factors in cSVD lesion burden in the brain is far from complete. This is exemplified by this case of identical twins with remarkably similar vascular risk profiles, where one twin had developed severe cSVD on neuroimaging with cognitive deficits, while the other twin had no cSVD. This case highlights the need to search for further causes of cSVD, also beyond genetic and conventional vascular risk factors. Identification of other potential risk factors or disease mechanisms should be a priority for cSVD research to improve our understanding, prevention and treatment of this common cause of vascular brain injury with major clinical consequences.

Objective: To evaluate the preliminary efficacy of remote ischemic conditioning (RIC) on patients with cerebral small vessel disease (SVD). Methods: Thirty patients diagnosed with symptomatic SVD within 30 days of onset were enrolled in this prospectively randomized controlled study for 1 year. All patients received routine medical treatment including treating vascular risk factors according to the guideline. Patients in the experimental group (n=14) were administered 5 cycles consisting of ischemia followed by reperfusion for 5 minutes on bilateral upper limbs twice daily for 1 year. Those in the control group (n=16) underwent sham ischemia-reperfusion cycles. Primary outcome was the change of cognitive function measured by mini-mental state examination (MMSE) and montreal cognitive assessment scale (MoCA), and secondary outcomes were changes of plasma biomarkers, cerebral hemodynamic parameters measured by vascular ultrasound and brain lesions measured by MRI FLAIR both at baseline and at the end of 1 year visit. Results: Compared with patients in the control group, patients in the RIC group had higher flow velocity (FV), and lower pulsatility index (PI), but without statistical difference. Patients in the RIC group had improvement in visuospatial and executive abilities (3.86±1.03 vs. 4.43±0.85, p=0.026), reduced plasma triglyceride (1.60±0.74 vs. 1.25±0.38, p=0.019), low density lipoprotein (2.89±0.81 vs. 2.26±0.67, p=0.003) and homocysteine (15.66±10.11 vs. 13.66±9.80 p=0.017). Similarly in the RIC group, the diastolic flow velocity (DFV) of middle cerebral artery (MCA) (right: 33.93±7.67 vs. 36.93±6.12, p=0.032; left: 33.93±7.67 vs. 36.93± 6.12, p=0.032) and the mean flow velocity (MFV) of left MCA (35.00±5.04 vs. 39.50±5.59, p=0.003) increased, and the PI of MCA (right: 1.11±0.19 vs. 1.02±0.14 p=0.030; left: 1.10±0.22 vs. 0.99±0.14, p=0.037) decreased. Conclusion: RIC appears to be potentially effective for improving cognition, enhancing cerebral perfusion, and modifying vascular risk factors in SVD patients. Further studies focusing on long-term neurological outcomes and potential mechanisms underlying RIC on SVD patients are needed.

Background: Changes in the extracranial vasculature may be associated with small vessel disease in the brain. We sought to examine the association of carotid stiffness and carotid diastolic diameter with white matter hyperintensity volume (WMHV), a magnetic resonance imaging (MRI) measure for cerebral small vessel disease, in a multi-ethnic community-based cohort. Methods: We evaluated 1140 stroke-free participants in the Northern Manhattan study who underwent brain MRIs and high-resolution carotid ultrasounds. We used linear regression to examine carotid stiffness and diastolic diameter with WMHV after adjusting for sociodemographics, lifestyle behaviors, and traditional vascular risk factors. Results: Among 1140 participants (mean age: 70.6±9.0 years; 61% women; 15% White, 16% Black, 59% Hispanics), the mean carotid stiffness was 8.19 ± 5.39, mean carotid diastolic diameter was 6.16 ± 0.93 mm, and mean WMHV 0.68 ± 0.84. In a fully adjusted model, diastolic diameter was associated with log-WMHV (β=0.10, p=0.001). In a stratified multivariable linear model, greater carotid arterial stiffness and diastolic diameter were associated with log-WMHV among Hispanics (β=0.15, p=0.005 and β=0.13, p<0.001, respectively), but not among blacks or whites. Conclusion: Greater carotid stiffness and diastolic diameter were associated with greater WMHV independent of demographics and traditional vascular risk factors, especially among Hispanics. Further studies are needed to understand how these large artery characteristics relate to WMH formation and lesion load. Carotid ultrasound may be a useful tool to assess the risk of increased brain white matter disease in a pre-clinical stage.

Introduction. Cerebral ischemic small-vessel disease (SVD), causing lacunar infarcts and white matter hyperintensities on brain magnetic resonance imaging (MRI), is a progressive disease associated with an increased risk of stroke, dementia and death. Increased arterial stiffness has been associated with ischemic stroke and cerebral SVD independently of common vascular risk factors. Objective. The aim of the study was to analyze arterial stiffness in our patients with symptomatic SVD. Methods. In a cross-sectional study design we included 30 patients with clinical and MRI evidence of cerebral SVD and 30 age-, gender- and risk factor-matched control subjects with no neurological diseases. Patients were evaluated at the Ultrasound Laboratory at the Neurology Clinic, Clinical Center of Serbia in Belgrade, during a three-month period (from September 1st to December 1st 2012). Baseline demographic and vascular risk factors were recorded. All patients underwent standard carotid ultrasound scans with measuring of intima-media thickness (IMT) and analysis of atheromatous plaques. Internal carotid artery stiffness was evaluated with the use of e-tracking option as beta stiffness index (BSI) value. Results. There were no differences between study groups in regard to degree of carotid stenosis and type of carotid plaques (p>0.05). Patients in SVD group had significantly higher mean IMT (p=0.0093) and mean BSI (p<0.0001) than subjects in the control group. No significant correlation was detected between IMT and BSI in SVD group (r=0.168; p=0.376). Brain lesions severity correlated with BSI (r=0.733; p<0.0001). Conclusion. Arterial stiffness is increased in symptomatic patients with SVD, independently of vascular risk factors and IMT.

Background and Purpose Left ventricular hypertrophy (LVH) is associated with the risk of stroke and dementia independently of other vascular risk factors, but its association with cerebral small vessel disease (CSVD) remains unknown. Here, we employed a systematic review and meta-analysis to address this gap.<br/>Methods Following the MOOSE guidelines (PROSPERO protocol: CRD42018110305), we systematically searched the literature for studies exploring the association between LVH or left ventricular (LV) mass, with neuroimaging markers of CSVD (lacunes, white matter hyperintensities [WMHs], cerebral microbleeds [CMBs]). We evaluated risk of bias and pooled association estimates with random-effects meta-analyses.<br/>Results We identified 31 studies (n=25,562) meeting our eligibility criteria. In meta-analysis, LVH was associated with lacunes and extensive WMHs in studies of the general population (odds ratio [OR]lacunes, 1.49; 95% confidence interval [CI], 1.12 to 2.00) (ORWMH, 1.73; 95% CI, 1.38 to 2.17) and studies in highrisk populations (ORlacunes: 2.39; 95% CI, 1.32 to 4.32) (ORWMH, 2.01; 95% CI, 1.45 to 2.80). The results remained stable in general population studies adjusting for hypertension and other vascular risk factors, as well as in sub-analyses by LVH assessment method (echocardiography/electrocardiogram), study design (cross-sectional/cohort), and study quality. Across LV morphology patterns, we found gradually increasing ORs for concentric remodelling, eccentric hypertrophy, and concentric hypertrophy, as compared to normal LV geometry. LVH was further associated with CMBs in high-risk population studies.<br/>Conclusions LVH is associated with neuroimaging markers of CSVD independently of hypertension and other vascular risk factors. Our findings suggest LVH as a novel risk factor for CSVD and highlight the link between subclinical heart and brain damage.

Objective: To study the association of cerebral microbleeds (CMB) on MRI and performance on a comprehensive neuropsychological test battery in a community based cohort free of stroke and dementia. Background: CMB represent hemorrhage-prone cerebral small vessel disease (SVD) and have been related to increased risk of dementia. In non-demented individuals, CMB may negatively affect cognition and the pattern of impaired cognitive performance may differ according to lesion topography. Methods: We evaluated 1744 Framingham Offspring Study participants (mean age 64.6 years, 54% women) attending a baseline examination (1998-2008), who had brain MRI allowing for CMB detection and underwent concurrent NP testing. Using multivariable linear regression we related CMB presence overall and stratified by brain location (lobar, deep or mixed) to performance on NP tests representing cognitive domains including memory, executive function, abstraction, language and visuospatial function. Results: CMB were observed in 7.7% of subjects (66% lobar, 20% deep, 14% mixed). After adjustment for sex, age, level of education and MRI markers of ischemic small vessel disease, presence of any CMB was associated with impaired performance on tests of abstraction (β -0.71, p=0.02) and language (β -0.13, p=0.04). The associations were attenuated after adjustment for vascular risk factors (hypertension, diabetes, smoking, prevalent cardiovascular disease). Lobar CMB showed similar marginal associations (p=0.05), also attenuated after adjustment for vascular risk factors. Mixed location CMB were associated with tests of executive function, an association that remained significant after adjustment for MRI markers of ischemic SVD and vascular risk factors (β-0.12, p= 0.02). CMB in only deep location did not show any significant association with NP test performance. Conclusions: CMB were associated with lower cognitive performance in a community-based sample of middle-aged adults. Our findings are limited given the cross sectional study design and small sample in subgroups of deep and mixed CMB, but concur with studies suggesting a negative impact of CMB on cognition, and expand prior studies by showing that the relations are independent of ischemic cerebral SVD.
