Introduction: Recently, various causative genes have been identified in adult-onset white matter disorders. Some of these genes cause cerebral small vessel disease (CSVD). However, the frequency of genetic CSVD is unknown in the group of adult-onset white matter disorders (leukoencephalopathy). The purpose of this study is to clarify the frequency of genetic CSVD in adult-onset leukoencephalopathy patients and to examine their clinical features. Methods: One hundred patients in the Japanese cohort were included. All patients had neurological symptoms/signs and white matter lesions of grade 3/III classified by Fazekas grade on magnetic resonance imaging. Initially, genetic tests for cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), high-temperature requirement A serine peptidase 1 (HTRA1)- related CSVD and retinovasculopathy with cerebral leukoencephalopathy (RVCL) were performed by Sanger method. For the remaining samples, we preformed whole exome sequencing. Patients were divided into groups according to the age at onset of neurological signs/symptoms and family history. Results: In 40 of 100 patients with leukoencephalopathy, we identified genetic mutations that cause CSVD: twenty-five patients with CADASIL,10 patients with HTRA1 -related CSVD, 3 patients with pseudoxanthoma elasticum (PXE), 1 patient with RVCL, and 1 patient with a mutation in COL4A1 . More than 85% patients have mutations in NOTCH3 or HTRA1 . In addition, we identified 3 patients with vanishing white matter disease, and 1 patient with X-linked adrenoleukodystrophy. The hereditary CSVDs other than CADASIL or HTRA1 -related CSVD were identified in the groups of age at onset ≤ 40 years-old irrespective of family history or age at onset ≤ 55 years-old with family history. Conclusions: The frequencies of genetic CSVDs were quite high among patients with leukoencephalopathy with neurological signs/symptoms. Although the genetic tests for CADASIL and HTRA1- related CSVD are sufficient for the most patients, we should consider the other genetic diseases especially for the patients with younger age onset of neurological signs/symptoms or positive family history.

ABSTRACT:Clinical differentiation between forms of progressive dementia can prove difficult, particularly when relatively rare forms of dementia are involved. Factors such as family history of dementia, age at onset, presenting features such as personality change, cognitive deficits, psychiatric symptoms, and clinical course (progressive deterioration; retention of skills over time) may prove useful for directing investigations to identify underlying pathology and genetic implications. This is illustrated by two patient reports. Each patient had the onset of memory/behavioral problems at approximately age 40 years, was initially given a psychiatric, non-dementing diagnosis, and had a positive family history for early onset behavioral and memory problems. After longitudinal assessment, the diagnosis of Alzheimer disease was confirmed at autopsy in one patient and a diagnosis of familial, adult-onset metachromatic leukodystrophy in the other.

Objective: Recent studies have shown the benefit of revascularization in select patients with extended window large vessel occlusion (EWLVO). We sought to assess the effect of cerebral small vessel disease (CSVD) burden on eligibility for intervention with mechanical thrombectomy (MT) and functional outcomes in patients with EWLVO. Methods: We conducted a retrospective single-center study of 135 patients with anterior circulation LVO who presented in the extended time window, 6 to 24 hours from LKW, between August 2018 and March 2020. All patients underwent perfusion imaging at initial presentation and those with target ischemic core to penumbra mismatch profiles, as defined by DAWN/DEFUSE3 criteria, were treated with MT. Included patients were evaluated for CSVD burden using T2-FLAIR MRI. The Fazekas scale (0-3) was used to quantify the amount of white matter T2 hyperintense lesions in both the periventricular (PVWM) and deep white matter (DWM). Patients’ functional outcomes were assessed at 90 days using the mRS. Multivariate ordinal logistic regression models were used and adjusted for age, gender, thrombus location and LKW to perfusion imaging time. Patient information was collected from the Houston Methodist Hospital Outcomes Based Prospective Endpoints in Stroke (HOPES) registry. Results: Of the 135 patients, 111 met imaging inclusion criteria for revascularization with MT for EWLVO. MT was deferred in 44 of these patients due to other clinical exclusions or patient refusal. Patients ineligible for MT were approximately 13 times more likely to have a higher PVWM Fazekas grade (OR =13.53, 95% CI. [2.94 - 62.39], p=0.001) and 17 times more likely to have a higher DWM Fazekas grade (OR =17.54, 95% CI. [4.20 - 73.17], p<0.001), when compared to patients who were eligible for MT. Patients who did not meet criteria for MT were nearly 7 times more likely to have poor functional outcomes at 90 days (OR =6.85, 95% CI. [2.09 - 22.44], p=0.001). Conclusion: Based on our analytical cohort of EWLVO patients, those with severe CSVD burden were more likely to be excluded from MT and had worse functional outcomes. Poor cerebrovascular reserve and diminished collateral flow leading to rapid infarct progression in patients with greater CSVD burden may be a potential explanation.

Some degree of ischemic injury to white matter tracts occurs naturally with age and is visible on magnetic resonance imaging as focal or confluent white matter hyperintensities (WMHs). Its relationship to cognition, however, remains unclear. To explore this, community-dwelling adults between the ages 55-80 years old completed structural imaging, neuropsychological testing, and questionnaires to provide objective measures and subjective experience of executive functioning. Volumetric lesion burden derived from structural MRI identified those with significant WMH burden (~10 cubic cm). Half of those recruited met this criterion and were designated as the cerebral small vessel disease (CSVD) group. Subjective complaints but not objective test scores differentiated adults with and without CSVD. Hierarchical clustering revealed two CSVD subgroups that differentiated those with impaired versus preserved executive function relative to controls. Overall these results provide some explanation for behavioural heterogeneity often observed in studies of age-related white matter changes. They also support the use of questionnaires to assess subjective complaints that may be able to detect subtle effects of pathology not evident on standardized cognitive scores.

Introduction: White matter hyperintensities (WMH) are a radiographic marker for cerebral small vessel disease (CSVD). Conditions altering cerebral venous outflow such as elevated central venous pressure and right atrial pressure in individuals with cardiac valvular disease have been implicated in the development of WMH. Hypothesis: We hypothesize that increased right-heart chamber size in individuals without significant cardiac valvular disease is associated with worse WMH. Methods: A retrospective chart review of adults with a brain MRI and a 2-dimensional transthoracic echocardiogram (TTE) was performed. Worst burden of WMH by way of Fazekas score, either periventricular or deep white matter, served as the primary outcome. Statistical analysis was performed using a multivariate ordinal logistic regression model. Results: A total of 132 individuals were included. Right atrial area (OR 0.93, 95% CI 0.87 to 1.00, p = 0.0041), right ventricular internal diameter (OR 0.48, 95%CI 0.27 to 0.83, p = 0.008) and left atrial area (OR 0.93, 95%CI 0.88 to 0.98, p = 0.007) was identified as being significant. Cardiac functional markers were not significant, including tricuspid annular plane systolic excursion (OR 0.99, 95%CI 0.93 to 1.05, p = 0.670), right ventricular ejection fraction (OR 0.99, 95%CI 0.96 to 1.02, p = 0.670) and left ventricular ejection fraction (OR 0.99, 95%CI 0.96 to 1.02, p = 0.567). Analysis of isolated DWM or PVWM Fazekas scores did not find significant predictors in relation to cardiac structure or function. Conclusions: Through non-invasive cardiac imaging, we identified that cardiac structural abnormalities as opposed to functional abnormalities were associated with worse WMH. Mechanistically this may result from altered intracerebral arteriovenous coupling or a shared pathophysiologic pathway between WMH and coronary microvascular disease.

Background: Association between high homocysteine level and cerebral small-vessel disease has been implicated in cross-sectional studies, but results from longitudinal studies have been less clear. The aim of this study was to investigate whether homocysteine level at 3-months poststroke relates to the occurrence of white matter changes (WMC), the surrogate of cerebral small-vessel disease. We also investigated whether it relates to the prognosis after ischemic stroke regarding the risk of dementia at 3-months and mortality in long-term follow-up. Methods: A total of 321 consecutive acute ischemic stroke patients aged 55 to 85 were included in the study and followed up to 12 years. Plasma homocysteine level and occurrence of WMC in MRI were measured 3 months poststroke and dementia according to DSM-III was evaluated at the same time. Findings: The median homocysteine level was 13.50 μmol/l (interquartile range [IQR] 10.60-18.50 μmol/l). Total of 81 patients (25.2%) had homocysteine level above 18.50 μmol/l. In logistic regression analysis, homocysteine level above 18.50 μmol/l was not associated with severe WMC nor with dementia at 3 months poststroke. In Kaplan-Meier analysis, homocysteine level above 18.50 μmol/l was not associated with survival in 12-year follow-up. For further analysis, the group was divided in quartiles according to homocysteine level. The quartiles did not differ in occurrence of severe WMC at baseline, in the risk of dementia at 3 months, nor in the risk of mortality in 12-year follow-up. Interpretation: In our poststroke cohort homocysteine level is not associated with WMC. Further, it does not relate to impaired prognosis manifested as dementia at 3 months or mortality in 12-year follow-up.

Introduction: Cerebrovascular small vessel disease, seen on brain imaging as lacunes and white matter hyperintensities (WMH), is a substrate for dementia in older adults. Diffusion tensor imaging (DTI) is thought to provide early signs of loss of white matter (WM) integrity due to microvascular disease and predicts WM hyperintensity volume. Retinal fundus photography provides surrogate measures of cerebral microvasculature. No studies have quantified the long-term association between retinal signs and DTI measures. Hypothesis: Microvascular retinal signs measured in midlife are associated with small vessel disease measured on brain magnetic resonance imaging (MRI) 18 years later, including reduced WM microstructural integrity (lower fractional anisotrophy [FA] and greater mean diffusivity [MD] by DTI), greater WM hyperintensity volume and greater lacune prevalence. Methods: In a biracial prospective cohort study, retinal signs were measured using fundus photography (1993-1995) with 3-T magnetic resonance imaging conducted in 2011-13. Multivariable-adjusted linear regression was used to quantify the relationships of retinal signs with WM measures. Prevalence of lacunar infarcts by retinal sign status was estimated using log binomial regression. Analyses were adjusted for age [linear and quadratic terms], education, sex, race, intracranial volume, body mass index, smoking, diabetes, hypertension, and ≥1 APOE ε4 alleles. Results: In 1829 men and women (60% [N=1100] female, 27% [N=489] black race, aged 50-72 years when retinal signs were measured), a binary measure comprised of two retinal signs suggestive of arteriolar damage due to hypertension (focal arteriolar narrowing and/or arteriovenous nicking) was associated with worse (lower) FA (standardized β=-0.19, 95% confidence interval [CI]=-0.35, -0.02), worse (higher) MD (β=0.15, 95% CI=0.00, 0.30), greater WM hyperintensity volume (β=0.15, 95% CI=0.01, 0.30), and greater prevalence of lacunes (prevalence ratio=1.33, 95% CI: 0.99, 1.80). Generalized arteriolar narrowing, measured as the central retinal arteriolar equivalent (CRAE, narrowest quartile vs. widest three quartiles) was associated with worse FA (β=-0.13, 95% CI=-0.24, -0.01) and worse MD (β=0.12, 95% CI=0.01, 0.23). Results did not differ by sex, race, hypertension status or APOE ε4 genotype. No associations were found for retinopathy, but only 56 participants had retinopathy. Conclusions: Consistent with prior work, and as expected based on a common underlying pathology, retinal signs predicted WM disease and lacunar infarcts 18 years later. Novel to this study, we found that retinal signs related to arteriolar damage also predicted loss of white matter microvascular integrity measured using DTI.
