The Association between Cerebral Small Vessel Disease and the Gut Microbiome: A Cross-Sectional Analysis
Cerebral small vessel disease (SVD) has been a research focus as a risk factor for both stroke and dementia.1 Cerebral SVD is characterised by brain magnetic resonance imaging (MRI) abnormalities, as silent lacunar infarcts (SLIs), white matter hyperintensities (WMHs), cerebral microbleeds (CMBs), and enlarged periventricular spaces (EPVSs).1 These findings are frequently encountered in patients with vascular risk factors, and are also common in patients with early stages of cognitive impairment.

Low NIHSS score large vessel occlusion caused by infective endocarditis treated with thrombectomy
A 24-year-old woman had undergone dental treatment 3 weeks before and had a mild fever for a week. She presented to the emergency department with the chief complaint of weakness in the right upper limb after waking up. She had mild paralysis of the right upper limb (National Institutes of Health Stroke Scale [NIHSS] score 1). Head magnetic resonance imaging (MRI) showed scattered infarcts in the left frontal and parietal lobes and left internal cerebral artery (ICA) occlusion (Fig. 1A, B). Cerebral angiography showed that the left ICA was occluded immediately after its origin (Fig.

Associations of carotid artery flow parameters with MRI markers of cerebral small vessel disease and patterns of brain atrophy
Cerebral small vessel disease (CSVD) affects small arteries, arterioles, veins and capillaries of the brain. Although a common and often silent condition occurring among healthy elderly people, it is associated with stroke, dementia, gait disturbances, cognitive decline and depression.1 –4 Magnetic resonance imaging (MRI) markers of CSVD include: white matter changes (WMC), microbleeds (MB) and lacunar infarctions (LAC).5 They can be investigated either individually or be viewed as a dynamic whole-brain disease.

Investigation of inpatient convalescent rehabilitation outcomes in branch atheromatous disease
Branch atheromatous disease (BAD) is a form of ischemic stroke characterized by unique findings in penetrating artery infarcts on magnetic resonance imaging (MRI) and progressive motor deficits in the acute phase.1-5 In daily practice, the most prominent clinical issue in patients with BAD is neurological deterioration and the consequent development of severe neurological sequelae requiring rehabilitation.

Correlation Between Severity of Carotid Stenosis and Vascular Reserve Measured by Acetazolamide Brain Perfusion Single Photon Emission Computed Tomography
This study examined that relationship. A total of 56 ICAs in 43 patients were included. Computed tomography scan or magnetic resonance imaging showed no evidence of infarction in any of these patients. Both iodine-123-N-isopropyl-p-iodoamphetamine (123IMP)–single photon emission computed tomography (SPECT) in the resting state and 123IMP-SPECT with acetazolamide (ACZ) enhancement were performed. Quantitated cerebral blood flow (CBF) images were acquired with the 123IMP autoradiography technique. The mean CBF without ACZ administration (resting CBF) and CVR in the middle cerebral artery territory were calculated using ste...

Efficacy and Safety of Single versus Dual Antiplatelet Therapy for Coiling of Unruptured Aneurysms
Conclusion: Our data suggest that dual antiplatelet therapy may better prevent ischemic complications from coiling for wide-necked aneurysms compared with single antiplatelet therapy.

Suitability of the Montreal Cognitive Assessment versus the Mini-Mental State Examination in Detecting Vascular Cognitive Impairment
The Mini-Mental State Examination (MMSE) has been criticized as being an insufficient screening test for patients with vascular cognitive impairment because of its insensitivity to visuospatial and executive functional deficits. The Montreal Cognitive Assessment (MoCA) was designed to be more sensitive to such deficits, and thus may be a superior screening instrument for vascular cognitive impairment. Twelve patients with extensive leukoaraiosis detected on magnetic resonance imaging (average age, 76.0 ± 8.7 years) underwent neurologic and cognitive testing, including MMSE and the Japanese version of the MoCA (MoCA-J). Ac...

Arterial Spin-Labeling Magnetic Resonance Imaging After Revascularization of Moyamoya Disease
Arterial spin labeling (ASL) magnetic resonance imaging (MRI) is a technique for depicting cerebral perfusion without contrast medium. The purpose of this study was to determine whether ASL can be used to detect hyperperfusion after revascularization for moyamoya disease as effectively as N-isopropyl-[123I]β-iodoamphetamine (123I-IMP) single-photon emission computed tomography (SPECT). Fifteen consecutive patients with moyamoya disease were included in the study. All patients underwent surgical revascularization. Postoperatively, regional cerebral blood flow (rCBF) was measured by flow-sensitive alternating inversion reco...

Diagnosis of Moyamoya Disease on Magnetic Resonance Imaging: Are Flow Voids in the Basal Ganglia an Essential Criterion for Definitive Diagnosis?
In this report, flow voids in the basal ganglia and cisternal flow voids of the sylvian valley were evaluated in patients with moyamoya disease, and their diagnostic value was verified. A total of 41 consecutive patients with moyamoya disease were included in this analysis. The number of flow voids in the basal ganglia and the sylvian valley were counted on each side by 3 observers. Then the numbers of flow voids were compared between the patients with moyamoya disease and controls. The patients with moyamoya disease had a significantly higher mean number of flow voids in the basal ganglia and the sylvian valley (P

Hippocampal Magnetic Resonance Imaging Abnormalities in Cardiac Arrest are Associated with Poor Outcome
Conclusions: Bilateral hippocampal hyperintensities on MRI may be a specific imaging finding that is indicative of poor prognosis in patients who suffer global hypoxic–ischemic injury. More research on the prognostic significance of this and similar neuroimaging patterns is indicated.

Cerebral White Matter Hyperintensity in African Americans and European Americans with Type 2 Diabetes
Previous studies involving inner city populations detected higher cerebral white matter hyperintensity (WMH) scores in African Americans (AAs) compared with European Americans (EAs). This finding might be attributable to the higher prevalence of cardiovascular disease (CVD) risk factors and poorer access to healthcare in AAs. Despite racial differences in CVD risk factor profiles, AAs have paradoxically lower levels of subclinical CVD. We hypothesized that AAs with diabetes and good access to healthcare would have comparable or lower levels of WMH as EAs. Racial differences in the distribution of WMH were analyzed in 46 AA...

Association of Physical Activity with the Visuospatial/Executive Functions of the Montreal Cognitive Assessment in Patients with Vascular Cognitive Impairment
Conclusions: These results suggest that MoCA is useful to detect a biologically determined specific relationship between physical activity and executive function. In addition, physical exercise, such as walking, may help enhance cognitive function in patients with vascular cognitive impairment of subcortical origin.

Thrombosis of a Developmental Venous Anomaly in Inflammatory Bowel Disease: Case Report and Radiologic Follow-up
We describe the clinical and neuroradiologic follow-up of a 62-year-old man with a history of inflammatory bowel disease (IBD) presenting with new onset epilepsy and intracranial hemorrhage caused by thrombosis of a DVA who fully recovered after treatment with oral anticoagulant therapy. Patients with IBD have an increased risk of thrombosis because of inflammatory activity and the hypercoagulable state. Here we describe the first case of DVA thrombosis in a patient with IBD, and we show clinical and neuroradiologic follow-up after anticoagulant therapy.

Penumbral Imaging by Using Perfusion Computed Tomography and Perfusion-Weighted Magnetic Resonance Imaging: Current Concepts
Perfusion computed tomography and perfusion-weighted magnetic resonance imaging are used to evaluate the extent of the area with ischemic penumbra; however, different parameters, algorithms, and software packages show significant discrepancies in the size of perfusion abnormalities, which should be minimized. Recently, cross-validation studies were performed using digital phantoms and have elucidated the precision and reliability of various penumbral imaging techniques. These research initiatives can promote further multicenter trials on recanalization therapies by providing accurate inclusion/exclusion criteria for approp...
