Background: Age and hypertension are widely considered to be the main risk factors for white matter hyperintensity (WMH), but they do not account for all the pathophysiological mechanisms of WMH.Therefore, identifying novel risk factors is significant to improve our understanding of the etiology and consequences of WMH. Objective: To examine the association of heart rate(HR) and common vascular risk factors with WMH burden in patients hospitalized for Cerebral Small Vessel Disease(CSVD) Method: The study consisted of 778 patients who underwent 24-hour ambulatory blood pressure and HR monitoring and brain magnetic resonance imaging(MRI). The relationship of HR measures and vascular risk factors with the presence of log WMHV4 was analyzed.Univariable and multivariable analysis was carried out to investigate the relationship of incidence of severe WMH (4th quartile, ≥19.64 ml) and HR measures and common vascular risk factors. Results: Multivariate analysis showed that WMHV was independently predicted by nighttime HR ( OR (95% CI): 1.041（1.02~1.062）, P<0.001),Homocysteine ( OR (95% CI): 1.019（1.005~1.033）, P=0.009), and cerebral infarction ( OR (95% CI): 0.463（0.31~0.691）, P<0.001), No similar association was observed for daytime HR、HR variability and other vascular risk factors . Conclusion: As nighttime HR、Hcy increased, log WMHV increased accordingly; furthermore, patients with cerebral infarction were more likely to have higher levels of WMHV. nighttime HR 、Hcy、cerebral infarction was associated with WMHV, suggesting independent roles of their in WMHV. The influence of HRV on WMHV needs to be addressed by further studies.

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.

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.

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.

The Relationship

Background: Prior studies have shown the association between periodontal disease, lacunar strokes and cognitive impairment. Using the Atherosclerosis Risk in Communities (ARIC) cohort study we investigated the relationship between periodontal disease (PD) and the development of MRI verified small vessel disease. Methods: Using the ARIC database data we extracted data for 1143 (mean age 77 years, 76% white, 24% African-American and 45% male) participants assessed for PD (N=800) versus periodontal health (N=343). These participants were assessed for small vessel disease on 3T MRI as measured by the log of white matter hyperintensity volume (WMHV). WMHV were derived from a semiautomated segmentation of FLAIR images. Student t-test was then used to evaluate the relationship between small vessel disease as the log of WMHV in subjects with PD or periodontal health. Based on WMHV the patients were grouped into quartiles and the association of PD with WMHV were tested using the group in periodontal health and lowest quartile of WMHV as the reference groups. Multinomial logistic regression was used to compute crude and adjusted odds ratio (OR) for the higher quartiles of WMHV compared to the reference quartile. Results: There was a significant increase in the presence of small vessel disease measured as log WMHV in the PD cohort as compared to periodontal health cohort with p= 0.023 on Independent Sample t-est. Based on WMHV the subjects were grouped into quartiles 0-6.41, >6.41-11.56, >11.56-21.36 and >21.36 cu mm3). PD was associated with only the highest quartile of WMHV on univariate (crude OR 1.77, 95% CI 1.23-2.56) and multivariable (adjusted OR 1.61, 95% CI 1.06-2.44) analyses. The later was adjusted for age, race, gender, hypertension, diabetes and smoking. Conclusion: Based on this prospective cohort there is data to suggest that PD may be associated with cerebral small vessel disease. Maintaining proper dental health may decrease future risk for the associated lacunar strokes and vascular cognitive impairment.

Total Homocysteine

Objectives: Increased serum total homocysteine (tHcy) levels have been associated with not only vascular injury but also dementia. However, given an association between Hcy and vascular injury, such as cerebral small-vessel disease (SVD) or renal impairment, to what extent Hcy would impact future dementia beyond these confouders is unknown. We assessed the predictive value of tHcy levels with the risk of dementia in patients with vascular risk factors, when controlling for the MRI-findings and renal imapirment. Methods: Within a Japanese cohort of partients with vascular risk factors in an observational study from 2001, we evaluated the association between tHcy levels at baseline, defined as a continuous variable (per 1 μmol/L) and as a categorical variable (the tertile of tHcy), the prevalence of MRI-findings, and incident all-cause dementia during follow-up. Baseline brain MRI was used to determine SVD (lacuna, white matter hyperintensities and cerebral microbleeds [CMBs]) and atrophy (medial-temporal lobe atrophy). Cox proportional hazards analyses were performed for predictors of dementia adjusting for age, sex, APOEε4 allele, educational level, cerebrovascular events, estimated glomerular filtration rate (eGFR), vascular risk factors, and MRI-findings. Results: Of the 643 subjects (mean:67.2±8.4years, male:59%, 12.9±2.6years of schooling), in multivariable analyses adjusted for age, sex, hypertension, cerebrovascular events, eGFR, and intima-media thickness, the highest tHcy tertile (vs lowest) were associated with lacuna, CMBs and strictly deep CMBs, respectively. During the mean 7.3-year follow-up (range:3-13), 47 incident dementia patients (Alzheimer’s disease:24; vascular dementia:18; mixed-type:3; other:2) were diagnosed. In multivariable analyses adjusted for age, sex, cerebrovascular events, eGFR, and MRI-findings, tHcy level or the highest tertile of tHcy for all-cause dementia remained significant, respectively (relative risk [RR]1.09: p=0.02, RR;2.59: p=0.021). Conclusions: Our results provide additional evidence of Hcy that leads to increased susceptibility to the risk of dementia, suggesting that this association may be mediated by independent mechanisms.

AbstractBACKGROUNDLittle is known of the mechanisms of cerebral small vessel disease (CSVD). Both atherosclerosis or non-atherosclerotic diffuse arteriopathy are involved.METHODSA single-center, prospective, case-control study was performed in consecutive patients with different CSVD manifestations. The study group consisted of 205 patients: 52 with lacunar stroke (LS), 20 with subcortical hemorrhagic stroke (HS), 50 with vascular dementia (VaD), 28 with vascular parkinsonism (VaP) and 55 controls (CG) free of cerebrovascular disease but with high vascular risk.RESULTSPatients with CSVD had significantly higher prevalence of vascular risk factors including hypertension, diabetes mellitus, polymetabolic syndrome and chronic kidney disease. Patients with CSVD had also significantly higher fasting blood glucose, homocysteine, fibrinogen, systolic blood pressure, IMT values and lower eGFR, albumin and HDL levels. After adjustment for age and sex, low eGFR, albumin and high levels of uric acid and fibrinogen were associated with all CSVD groups, elevated fasting glucose was related to LS and HS. In the multivariate analysiss, the independent predictors for CSVD were female sex, low albumin, high fibrinogen, fasting glucose and uric acid. Patients with LS had significantly higher IMT values comparing to other CSVD groups, patients with VaP had a trend towards higher homocysteine levels.CONCLUSIONRisk factor profile for CSVD as a whole differs from subjects with proatherogenic profile without history of cerebrovascular disease. Our results support the concept that CSVD is not homogeneous, and that unique risk factors profiles exist for different clinical manifestations of the disease.

Background Evidence suggests that enlarged perivascular spaces (PVSs) may represent a marker for cerebral small‐vessel disease. We investigated whether vascular risk factors are correlated with visible PVS in older adults. Methods and Results This population‐based study included 530 participants (age ≥60 years) who were free from dementia and functional dependence, derived from the Swedish National study on Aging and Care in Kungsholmen (2001–2003). We collected data on demographics, vascular risk factors, and health conditions through interviews, clinical examinations, laboratory tests, and patient registers. Cerebral PVSs and white matter hyperintensities on magnetic resonance images were visually assessed with semiquantitative visual rating scales. Data were analyzed using the general linear regression models. After controlling for demographics and cardiovascular disease, very high blood pressure (≥160/100 mm Hg) was significantly associated with global PVS score (β‐coefficient, 1.30; 95% CI, 0.06–2.53) and orthostatic hypotension was associated with PVS score in the basal ganglia (β‐coefficient 0.37; 0.03–0.70), but the associations became non‐significant when adjusting for white matter hyperintensity load. Orthostatic hypotension was significantly associated with global and lobar PVS scores in carriers but not in noncarriers of the APOE ε4 allele. Global or regional PVS score was not significantly associated with other traditional vascular risk factors such as smoking, diabetes mellitus, physical inactivity, and overweight or obesity. Conclusions This study provides limited evidence supporting a correlation of magnetic resonance imaging–visible PVS with traditional vascular risk factors in older adults. The association of orthostatic hypotension with lobar PVS among APOE ε4 carriers suggests that lobar PVS may be a marker for amyloid‐associated small‐vessel disease.
