To assess whether high cerebral microbleeds (CMBs) are associated with carotid intima-media thickness (CIMT), a marker of systemic atherosclerosis, we cross-sectionally evaluated participants from a community-based study, the I-Lan Longitudinal Aging Study. The participants' demographics and cardiovascular risk factors were determined by questionnaire and/or laboratory measurements. CIMT was measured by ultrasonography. CMBs were assessed by susceptibility-weighted-imaging on 3 T MRI. Of the 962 subjects [62...

Metabolic syndrome is a cluster of cardiovascular risk factors defined by the presence of abdominal obesity, glucose intolerance, hypertension and/or dyslipidemia. It is a major public health epidemic worldwide, and a known risk factor for the development of cognitive dysfunction and dementia. Several studies have demonstrated a positive association between the presence of metabolic syndrome and worse cognitive outcomes, however, evidence of brain structure pathology is limited. Diffusion tensor imaging has offered new opportunities to detect microstructural white matter changes in metabolic syndrome, and a possibility to detect associations between functional and structural abnormalities...

BACKGROUND AND AIMS: Cerebral white matter hyperintensity (WMH) is commonly found in ischemic stroke patients, especially when accompanied by intracranial atherosclerosis (ICAS). However, the relationship between WMH and ICAS in a healthy population has not been evaluated. METHODS: A total of 3159 healthy subjects who underwent health checkups, including brain magnetic resonance imaging and angiography, were enrolled. ICAS was defined as an occlusion or more than 50% stenosis of intracranial vessels on magnetic resonance angiography...

BACKGROUND: In patients with craniosynostosis, intracranial pressure (ICP) has been reported to increase even in the absence of overt symptoms. The early and non-invasive detection of intracranial hypertension is important for reducing the risk of abnormal brain development in pediatric patients. PURPOSE: To assess whether the apparent diffusion coefficient (ADC) of white matter during the cardiac cycle (ΔADC) would change after surgery to relieve ICP in children with craniosynostosis...

BACKGROUND: Higher dietary salt intake increases the risk of stroke and may increase white matter hyperintensity (WMH) volume. We hypothesized that a long-term higher salt intake may be associated with other features of small vessel disease (SVD). METHODS: We recruited consecutive patients with mild stroke presenting to the Lothian regional stroke service. We performed brain magnetic resonance imaging, obtained a basic dietary salt history, and measured the urinary sodium/creatinine ratio...

The approaches that facilitate white matter plasticity may prompt functional recovery after a stroke. The effects of different exercise methods on motor recovery in stroke rats have been investigated. However, it is not clear whether their effects on axonal plasticity different. The aim of this study was to compare the effects of the forced running wheel exercise (RWE) and skilled reaching training (SRT) on axonal plasticity and motor recovery. Cortical infarctions were generated in stroke-prone renovascular hypertensive rats...

White matter hyperintensities (WMH) can be incidentally found in patients with carotid atherosclerosis on brain magnetic resonance imaging (MRI). We investigated the relationship between WMH and characteristics of carotid plaques in asymptomatic patients without indication for carotid revascularization. We prospectively screened 235 consecutive patients with carotid stenosis <70%. After excluding patients with confounding causes of cerebral damage, 67 asymptomatic patients underwent carotid computed tomography angiography (CTA), contrast-enhanced ultrasound and brain MRI...

High neutrophil to lymphocyte ratio (NLR) is correlated with the occurrence, morbidity and mortality of cerebrovascular disease as a marker of systemic inflammation. However, its effect on cerebral white matter hyperintensity (WMH) is unclear. We investigated high NLR burden as a surrogate marker of WMH volume in a healthy population. Healthy subjects with voluntary health check-ups between January 2006 and December 2013, including brain MRI and laboratory examination, were collected. WMH volumes were rated quantitatively...

In amyloid β-related angiitis of the central nervous system (also called cerebral amyloid angiopathy-related inflammation), cerebral amyloid angiopathy occurs in association with primary vasculitis of small- and medium-sized leptomeningeal and cortical arteries. To avoid brain biopsy, clinicoradiological criteria (including clinical features due to inflammation-related uni/multifocal white matter hyperintensities) for the diagnosis of cerebral amyloid angiopathy-related inflammation have been validated recently...

While recent 'big data' analyses discovered structural brain networks that alter with age and relate to cognitive decline, identifying modifiable factors that prevent these changes remains a major challenge. We therefore aimed to determine the effects of common cardiovascular risk factors on vulnerable gray matter (GM) networks in a large and well-characterized population-based cohort. In 616 healthy elderly (258 women, 60-80 years) of the LIFE-Adult-Study, we assessed the effects of obesity, smoking, blood pressure, markers of glucose and lipid metabolism as well as physical activity on major GM-networks derived using linked independent component analysis...

AIM: The response to donepezil in patients with Alzheimer's disease varies, and it is important to identify the potential responder before therapy. Cerebral white matter changes (WMC) are frequently observed in older patients, and the effect of WMC on therapeutic response remains controversial. The present study aimed to investigate the relationships between the location of WMC, severe WMC and the response to donepezil. METHODS: Among 418 patients with Alzheimer's disease receiving donepezil, 196 patients were eligible for analysis...

OBJECTIVE: Women with a history of preeclampsia are at an increased risk of hypertension and structural brain changes. However, the combined effect of both preeclampsia and late-life hypertension on brain structural changes is not known and was investigated in this study. METHODS: Participants were identified from the population-based Rochester Epidemiology Project cohort. Four groups of women were recruited and investigated in this study: first, women with a history of normotensive pregnancy who have late-life hypertension (n = 8, median age = 62), second, women with a history of normotensive pregnancy who do not have late-life hypertension (n = 32, median age = 59), third, women with a history of preeclampsia who have late-life hypertension (n = 24, median age = 60), and fourth, women with a history of preeclampsia who do not have late-life hypertension (n = 16, median age = 57)...

Importance: Reemergence of previous stroke-related deficits (or poststroke recrudescence [PSR]) is an underrecognized and inadequately characterized phenomenon. Objective: To investigate the clinical features, triggers, and risk factors for PSR. Design, Setting, and Participants: This retrospective study incorporated a crossover cohort study to identify triggers and a case-control study to identify risk factors. The study used the Massachusetts General Hospital Research Patient Data Repository to identify patients for the period January 1, 2000, to November 30, 2015, who had a primary or secondary diagnosis of cerebrovascular disease, who underwent magnetic resonance imaging of the brain at least once, and whose inpatient or outpatient clinician note or discharge summary stated the term recrudescence...

OBJECTIVES: We evaluate the alternative use of texture analysis for evaluating the role of blood-brain barrier (BBB) in small vessel disease (SVD). METHODS: We used brain magnetic resonance imaging from 204 stroke patients, acquired before and 20 min after intravenous gadolinium administration. We segmented tissues, white matter hyperintensities (WMH) and applied validated visual scores. We measured textural features in all tissues pre- and post-contrast and used ANCOVA to evaluate the effect of SVD indicators on the pre-/post-contrast change, Kruskal-Wallis for significance between patient groups and linear mixed models for pre-/post-contrast variations in cerebrospinal fluid (CSF) with Fazekas scores...
