Correlation Between Intracranial Arterial Calcification and Imaging of Cerebral Small Vessel Disease
Conclusion: Intracranial artery calcification is common in patients with ischemic cerebrovascular disease and the intracranial carotid artery is most frequently affected. Intracranial arterial calcifications might be associated with imaging markers of SVD and are highly correlated with WMHs, lacunes, and CMBs. Quantification of calcification on CT provides additional information on the pathophysiology of SVD. Intracranial arterial calcification could act as a potential marker of SVD. Introduction Atherosclerosis is a systemic vascular process that is considered a major cause of cerebrovascular and cardiovascular di...

Air pollution linked to silent strokes
Conclusion This cross-sectional study has suggested a link between exposure to small particles in the air (one form of pollution) and the presence of "silent stroke" in older adults – small areas of damage to the brain tissue that are not severe enough to cause obvious symptoms. There are a number of limitations to be aware of when assessing the results of this study: While there was an association between particulate matter in the air and total brain volume, this was no longer statistically significant after taking into account whether people have conditions such as high blood pressure, which can also affec...

Cerebral Small Vessel Disease and Renal Function: Systematic Review and Meta-Analysis
Conclusion: We found no specific association between renal impairment and lacunar stroke, but we did find that in individuals who had not had a stroke, having more SVD features on imaging was associated with a worse renal function, which remained significant after controlling for hypertension. However, this finding does not exclude a powerful co-associate effect of age or vascular risk factor exposure. Future research should subtype lacunar stroke sensitively and control for major risk factors.Cerebrovasc Dis 2015;39:39-52

Consecutive Slides on Axial View Is More Effective Than Transversal Diameter to Differentiate Mechanisms of Single Subcortical Infarctions in the Lenticulostriate Artery Territory
Conclusion: Consecutive slides on axial view (≥4 consecutive slices) might be more effective than transversal diameter to identify the atherosclerotic mechanisms of SSIs in the lenticulostriate artery territory. Clinical Trial Registration: http://www.clinicaltrials.gov. Unique identifier: NCT00664846 Introduction Single subcortical infarctions (SSIs) have been considered to be caused by lipohyalinosis degeneration in small artery disease, traditionally called lacunar infarct (1). However, atherosclerosis occurring in the parental artery blocking the orifice of the branch artery or atherosclerosis in the p...

Characterizing the Penumbras of White Matter Hyperintensities and Their Associations With Cognitive Function in Patients With Subcortical Vascular Mild Cognitive Impairment
Conclusion In this study, reduced CBF and FA and increased MD in the inner NAWM layers for both PVWMH and DWMH suggested extensive WM alterations beyond the visible WM lesions commonly observed on clinical MRI of svMCI subjects. CBF penumbras cover more extensive WM at risk than DTI penumbras, suggesting the likelihood that compromised CBF precedes white matter integrity changes, and CBF penumbras may be a potential target for the prevention of further microstructural white matter damage. The imaging parameters investigated, however, did not correlate to cognition. Author Contributions YZ, QX, and XG conceived and desig...

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Preserve the Brain Primary Goal in the Therapy of Atrial Fibrillation ∗
Treatment of atrial fibrillation (AF) involves 3 major strategies: prevention of stroke, maintenance of sinus rhythm, and rate control (1). Stroke is the most dreaded complication of AF, and its prevention is key. Anticoagulation with warfarin and the newer agents dabigatran, rivaroxaban, and apixaban is highly effective in preventing strokes in patients with AF (1,2,3,4). However, defining the appropriate patient for anticoagulant therapy is not an exact science, and the stroke risk schema CHADS2 (Congestive heart failure, Hypertension, Age ≥75 years, Diabetes mellitus, previous Stroke/transient ischemic attack) and CH...

A Case of Transient Global Amnesia: A Review and How It May Shed Further Insight into the Neurobiology of Delusions
Conclusion In closing, our patient’s episode of TGA combined with her emotional and perceptual response lends credence to the proposal of a “fear/paranoia” circuit in the genesis of paranoid delusions—a circuit incorporating amygdala, frontal, and parietal cortices. Here, neutral or irrelevant stimuli, thoughts, and percepts come to engender fear and anxiety, while dysfunction in frontoparietal circuitry engenders inappropriate social predictions and maladaptive inferences about the intentions of others.[54] Hippocampus relays information about contextual information based on past experiences and the current situat...

Acute Silent Brain Infarction in Monocular Visual Loss of Ischemic Origin
Background and Purpose: Non-arteritic branch/central retinal artery occlusions (BRAO/CRAO) and amaurosis fugax (AF) are predominantly caused by embolism. Additionally, transported embolic material could cause ischemic stroke. The aim of the study was to investigate the prevalence, pattern and underlying cause of concurrent acute brain infarctions in unselected patients with RAO and AF. Methods: A total of 213 consecutive patients with BRAO (20.7%), CRAO (47.4%), or AF (31.9%) were retrospectively studied from 2008 to 2013. Magnetic resonance imaging (MRI) was used to detect acute brain infarctions and a cardiovascular work...

Investigating silent strokes in hypertensives: a magnetic resonance imaging study (ISSYS): rationale and protocol design
DiscussionImproving the knowledge on the frequency and determinants of these lesions in our setting might help in the future to optimize treatments or establish new preventive strategies to minimize clinical and socioeconomic consequences of stroke and cognitive decline.

Interaction of incidental microbleeds and prior use of antithrombotics with early hemorrhagic transformation: Causative or protective ?
Conclusion: Presence of incidental CMBs was not associated with increased risk for early HT of an ischemic stroke. Interestingly, the prior intake of antiplatelets was found to be protective against HT of ischemic stroke.

Studying the imaging features and infarction mechanism of vertebrobasilar dolichoectasia with high-resolution magnetic resonance imaging
In this study, we retrospectively analyzed the imaging characteristics of high-resolution magnetic resonance imaging (HR-MRI) in patients with VBD to explore the possible mechanisms of ischemic stroke (IS) in patients with VBD. Patients with VBD were recruited from the HR-MRI database between July 2017 and June 2021. HR-MRI was used to evaluate the diameter, bifurcation height, laterality, arterial dissection, and atherosclerotic plaques of the basilar artery (BA). Transcranial Doppler was used to measure the vertebrobasilar mean velocity (Vm), peak systolic velocity (Vs), end-diastolic velocity (Vd), and pulsatile index. ...
