BACKGROUND AND PURPOSE: Despite extensive studies on post-stroke depression (PSD), the role of the total burden of cerebral small-vessel disease (cSVD) in its pathogenesis remains unclear. METHODS: We conducted a magnetic resonance imaging (MRI)-based cohort study to investigate the relationship between total MRI burden of cSVD and PSD among patients with first-ever lacunar stroke. From June 2013 to January 2016, 374 patients were consecutively recruited. PSD was identified using the Chinese version of the Structured Clinical Interview for DSM-IV...

Cardio-cerebrovascular disease greatly influences the prognosis of diabetic patients. Silent lacunar infarcts, white matter lesions (WMLs), and cerebral microbleeds are magnetic resonance imaging (MRI) markers of cerebral small vessel disease (SVD) and as they are associated with stroke and dementia, prevention of their incidence and progression is important in clinical practice. The findings of previous autopsy and clinical studies suggest that lacunar infarcts are more prevalent in diabetic patients. On the other hand, the findings of studies on an association between diabetes and WMLs have been inconsistent...

Little is known about the significance of asymptomatic intra-cranial lesions (ICL) identified by brain MRI in coronary artery disease (CAD) patients. Silent cerebral lesions are suggested to be associated with arterial stiffness in healthy subjects. We investigated whether subclinical ICL are associated with arterial stiffness and the prognosis in CAD patients without medical history of cerebrovascular diseases. We recruited CAD patients who required percutaneous coronary intervention (PCI), did not meet exclusion criteria, and agreed with MRI before PCI...

BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited cerebral microangiopathy presenting with variable features, including migraine, psychiatric disorders, stroke, and cognitive decline and variable disability. On neuroimaging, CADASIL is characterized by leukoencephalopathy, multiple lacunar infarcts, and microbleeds. Previous studies suggest a possible role of endothelial impairment in the pathogenesis of the disease...

A 67-year-old right-handed woman experienced a sudden anterograde and retrograde short-term memory deficit that recovered on the next day. Magnetic resonance imaging (MRI) showed a spotty high-intensity lesion in the left putamen in the diffusion-weighted and fluid-attenuated inversion recovery images. Transient global amnesia due to lacunar infarction of the left putamen was diagnosed. Transient global amnesia is characterized by a sudden onset of anterograde amnesia that disappears within 24 hours. The cause of transient global amnesia is still uncertain...

Lacunar cerebral infarction (LI) is one of risk factors of vascular dementia and correlates with progression of cognitive impairment including the executive functions. However, little is known on spatial navigation impairment and its underlying microstructural alteration of white matter in patients with LI and with or without mild cognitive impairment (MCI). Our aim was to investigate whether the spatial navigation impairment correlated with the white matter integrity in LI patients with MCI (LI-MCI). Thirty patients with LI were included in the study and were divided into LI-MCI (n=17) and non MCI (LI-Non MCI) groups (n=13) according neuropsychological tests...

The aim of this study was to determine whether pulse wave velocity (PWV), a marker of vascular endothelial impairment and arteriosclerosis, predicts future ischemic stroke in patients who developed acute lacunar infarction. Patients with a first-ever ischemic stroke due to acute lacunar infarction were enrolled in this study. An oscillometric device (Form PWV/ABI; Omron Colin, Tokyo, Japan) was used to measure brachial-ankle PWV 1 week after stroke onset. Patients were followed for at least 5 years. The main end point of the study was recurrent ischemic stroke...

PURPOSES: Few population-based MRI studies on stroke, particularly in African-descent populations, are available. Based on a 1-year Afro-Caribbean population-based study MRI, ischemic stroke characteristics were extensively analyzed. METHODS: All strokes occurring in Martinique (390,371 inhabitants) were prospectively included. Ascertainment was based, whenever possible, on MRI. All patients were categorized as single- (subclassified as cortical, cortical-subcortical, subcortical, lacunar) or multiple-lesion pattern, and vascular (single, multiple or junctional) territory...

Imaging is critical in the diagnosis and treatment of dementia, particularly in vascular cognitive impairment, due to the visualization of ischemic and hemorrhagic injury of gray and white matter. Magnetic resonance imaging (MRI) and positron emission tomography (PET) provide structural and functional information. Clinical MRI is both generally available and versatile - T2-weighted images show infarcts, FLAIR shows white matter changes and lacunar infarcts, and susceptibility-weighted images reveal microbleeds...

BACKGROUND: It has been reported that some patients with lacunar infarction have transient ischemic attacks (TIAs) before stroke. This study was aimed at evaluating the factors and prognostic value related to TIAs preceding acute lacunar stroke. METHODS: A total of 1,424 patients were admitted to the hospital for first-ever ischemic stroke. Of which 314 patients with acute lacunar infarction were enrolled for this study. The patients were divided into 2 groups based on the occurrence of TIAs before stroke...

BACKGROUND: It is well known that renal dysfunction and cerebral small-vessel disease (SVD), including microbleed, lacunar infarction, and white matter lesion (WML), are associated with poor prognosis after ischemic stroke. However, the prognostic relationship between renal dysfunction and SVD has not been well evaluated in acute ischemic stroke survivors. Therefore, in this study, we evaluated the prognostic relationships between estimated glomerular filtration rate (eGFR) and cerebral SVD after acute ischemic stroke...

Arterial structure and function change progressively with advancing age. Owing to long-lasting repetitive stretch with intermittent cardiac contraction, elastic fibers in the tunica media of large arteries gradually degenerate and are replaced by collagenous fibers. Such medial degeneration causes elastic arteries to stiffen and dilate. However, the speed of the vascular aging varies considerably among individuals; a discrepancy often exists between the chronological age of an individual and the biological age of his or her arteries...

Stroke is known to frequently recur in patients with a history of cerebrovascular disease, and the control of hypertension is extremely important for the treatment of those patients. The robust relationship between the recurrent cerebrovascular disease and blood pressure control has been demonstrated in large-scale clinical studies. The antihypertensive drug therapy significantly reduces the recurrence rate of all types of cerebrovascular disease, incidences of myocardial infarction and all vascular events...

Observational studies have conveyed the connection between hypertension and cognitive impairment. Several forms of dementia are more frequent in hypertensive subjects or those with previous history of hypertension compared to subjects with normal blood pressure.In many studies, hypertension occuring in mid-life is a risk factor of dementia occuring in later age. Long-standing hypertension will induce structural damages in the brain. It is also widely known that hypertension attributes to small vessel diseases causing lacunar infarcts and white matter lesions associated with cognitive decline...

INTRODUCTION: The poststroke acute and rehabilitation length of stay (LOS) are key markers of stroke care efficiency. This study aimed to describe the characteristics and identify the predictors of poststroke acute, rehabilitation and total LOS. This study also defined a subgroup of patients as "short" LOS and compared its complication rates and functional outcomes in rehabilitation with a "long" acute LOS group. MATERIALS AND METHODS: A prospective cohort study (n = 1277) was conducted in a dedicated rehabilitation unit within a tertiary academic acute hospital over a 5-year period between 2004 and 2009...

BACKGROUND AND PURPOSE: The presence of subclinical vascular brain disease, including white matter lesions and lacunar infarcts, substantially increases the risk of clinical stroke. White matter microstructural integrity is considered an earlier, potentially better, marker of the total burden of vascular brain disease. Its association with risk of stroke, a focal event, remains unknown. METHODS: From the population-based Rotterdam Study, 4259 stroke-free participants (mean age: 63...
