Moyamoya syndrome is an unusual cerebrovascular disorder, which has rarely been reported in association with hereditary spherocytosis. We present the case of a 6-year-old boy with hereditary spherocytosis who was diagnosed with Moyamoya syndrome following a stroke. We discuss why these conditions may coexist and briefly outline the management of such children.

BACKGROUND: HIV+ patients on highly active antiretroviral therapy (HAART) with suppressed viral loads have a low incidence of HIV-associated dementia, but increased prevalence of milder forms of HIV-associated neurocognitive disorders (HAND). These milder forms of HAND are often associated with minimal histological abnormalities, and their pathophysiology is unclear. Comorbidities, altered amyloid metabolism, accelerated brain aging, and activated interferon responses are suspected to play a role in HAND pathogenesis in HAART-treated persons...

Cigarette smoking (CS) is associated with vascular endothelial dysfunction in a causative way primarily related to the TS content of reactive oxygen species (ROS), nicotine, and inflammation. TS promotes glucose intolerance and increases the risk of developing type-2 diabetes mellitus (2DM) with which it shares other pathogenic traits including the high risk of cerebrovascular and neurological disorders like stroke via ROS generation, inflammation, and blood-brain barrier (BBB) impairment. Herein we provide evidence of the role played by nuclear factor erythroid 2-related factor (Nrf2) in CS-induced cerebrobvascular/BBB impairments and how these cerebrovascular harmful effects can be circumvented by the use of metformin (MF; a widely prescribed, firstline anti-diabetic drug) treatment...

Interspecies differences, anatomical and physiological aspects as wells as simplified study designs contribute to an overestimation of treatment effects and limit the transferability of experimental results into clinical applications. Confounders of cell therapies for cerebrovascular disorders (CVD) include common CVD comorbidities, frequent medications potentially affecting endogenous and transplanted stem cells, as well as age- and immune-system-related effects. All of those can contribute to a substantial modelling bias, ultimately limiting the prospective quality of preclinical research programs regarding the clinical value of a particular cell therapy...

BACKGROUND: Moyamoya disease is an idiopathic progressive cerebrovascular steno-occlusive disorder characterized by the formation of numerous collaterals called moyamoya vessels. Accurate evaluation of vascular status and CBF is needed for prompt treatment to prevent ischemic and/or hemorrhagic events. The pathogenesis of the ivy sign on fluid attenuated inversion recovery (FLAIR) images of moyamoya disease patients is unclear. We report a moyamoya disease case wherein the ivy sign changed in relation to SPECT-measured CBF during progression and following treatment...

Stroke is a leading cause of death in adult life, closely behind ischemic heart disease, and causes a significant and abiding socioeconomic burden. However, current therapies are not able to ensure full neurologic and/or sequelae-free recovery to all stroke survivors. We believe treatment efficacy and patient rehabilitation could be enhanced significantly by targeting blood-brain barrier (BBB) deregulation and inflammation-induced barrier loss occurring after stroke. In this pathological context, bone marrow-derived endothelial progenitor cells (EPC) enter the bloodstream towards the lesion site but their insufficient numbers and impaired angiogenic ability compromise neurovascular regeneration...

Sickle cell disease is a common and life-threatening haematological disorder that affects millions of people worldwide. Abnormal sickle-shaped erythrocytes disrupt blood flow in small vessels, and this vaso-occlusion leads to distal tissue ischaemia and inflammation, with symptoms defining the acute painful sickle-cell crisis. Repeated sickling and ongoing haemolytic anaemia, even when subclinical, lead to parenchymal injury and chronic organ damage, causing substantial morbidity and early mortality. Currently available treatments are limited to transfusions and hydroxycarbamide, although stem cell transplantation might be a potentially curative therapy...

Cerebrovascular disease typically manifests with stroke, cognitive impairment, or both. Vascular cognitive impairment refers to all forms of cognitive disorder associated with cerebrovascular disease, regardless of the specific mechanisms involved. It encompasses the full range of cognitive deficits from mild cognitive impairment to dementia. In principle, any of the multiple causes of clinical stroke can cause vascular cognitive impairment. Recent work further highlights a role of microinfarcts, microhemorrhages, strategic white matter tracts, loss of microstructural tissue integrity, and secondary neurodegeneration...

OBJECTIVE: Antiphospholipid antibody syndrome (APS) is one of the most common acquired thrombophilic disorders resulting in arterial and venous thromboses. APS is a major cause for cerebrovascular accidents or stokes, myocardial infarction, venous thromboembolism and recurrent abortions/pregnancy losses especially in young patients. APS patients have an increased risk of atherosclerotic cardiovascular events. There are only two studies on lipid abnormalities in APS patients. None of them have studied the relationship between individual laboratory tests for APS and lipid profile abnormalities...

BACKGROUND: Cerebrovascular accident (CVA) is the third leading cause of death and disability in developed countries. Anyone suspected of having a stroke should be taken immediately to a medical facility for diagnosis and treatment. The symptoms that follow a stroke aren't significant and depend on the area of the brain that has been affected and the amount of tissue damaged. Parameters for predicting long-term outcome in such patients have not been clearly delineated, therefore the aim of this study was to investigate this possibility and to test a system that might practicably be used routinely to aid management and predict outcomes of individual stroke patients...

Neurovascular changes are likely to interact importantly with the neurodegenerative process in idiopathic Parkinson's disease (IPD). Markers of neurovascular status (NVS) include white matter lesion (WML) burden and arterial spin labelling (ASL) measurements of cerebral blood flow (CBF) and arterial arrival time (AAT). We investigated NVS in IPD, including an analysis of IPD clinical phenotypes, by comparison with two control groups, one with a history of clinical cerebrovascular disease (CVD) (control positive, CP) and one without CVD (control negative, CN)...

: Metabolic syndrome (MetS) is a common and complex disorder combining hypertension, obesity, dyslipidemia, and insulin resistance. MetS represents a risk factor for changes in cognitive functions in older age, and several studies have suggested that MetS may be linked to dementia. This article reviews the main evidences about the relationship between MetS and neurodegenerative disease. Starting from an epidemiological point of view, the article analyzes medico-social aspects related to MetS, considering the reduction of work capacity and the condition of disability that it involves...
