Advanced lesion mapping and connectivity analyses are currently the main tools used to understand the mechanisms underlying post-stroke cognitive deficits. However, the factors contributing to pre-stroke architecture of cognitive networks are often ignored, even though they reportedly play a decisive role in the manifestation of cognitive impairment in neurodegeneration. The present review on post-stroke cognitive deficits therefore adopts the concept of brain and cognitive reserve, which was originally developed to account for the individual differences in the course of aging and neurodegenerative diseases...

Leukoaraiosis or white matter hyperintensities are frequently observed on magnetic resonance imaging of stroke patients. We investigated how white matter hyperintensity volumes affect stroke outcomes, generally and by subtype. In total, 5035 acute ischaemic stroke patients were enrolled. Strokes were classified as large artery atherosclerosis, small vessel occlusion, or cardioembolism. White matter hyperintensity volumes were stratified into quintiles. Mean age (± standard deviation) was 66.3 ± 12.8, 59.6% male...

Futile recanalization occurs when successful recanalization fails to improve clinical outcome in acute ischemic stroke patients. Predictors of futile recanalization are still debated and may help in selecting patients for reperfusion strategies. We aim to determine whether leukoaraiosis may be useful in predicting futile recanalization in acute ischemic stroke patients treated by endovascular mechanical thrombectomy. We included in the analysis patients with acute ischemic stroke due to anterior circulation large vessel occlusion undergoing endovascular mechanical thrombectomy obtaining complete vessel recanalization...

BACKGROUND: Diabetes is the most common metabolic disease with many chronic complications, and cognitive disorders are one of the common complications in patients with diabetes. Previous studies have showed that autophagy played important roles in the progression of metabolic syndrome, diabetes and other diseases. So we investigated whether aged diabetic mice are prone to be associated with the cognitive and affective disorders and whether Beclin-1-mediated autophagy might be involved in thepahological process...

BACKGROUND: In India, the correlates of leukoaraiosis (LA) have not been widely reported. This study was designed to investigate the factors which correlate with LA. MATERIALS AND METHODS: We included patients with LA who consented for the study and graded their severity on the basis of Fazekas scale. We excluded patients with LA who did not consent/cooperate for the study as also patients with other white matter changes which mimic LA. RESULTS: LA is a common and under-rated cause of disability...

REVIEW
Suzanne M de la Monte
Alzheimer's disease (AD) should be regarded as a degenerative metabolic disease caused by brain insulin resistance and deficiency, and overlapping with the molecular, biochemical, pathophysiological, and metabolic dysfunctions in diabetes mellitus, non-alcoholic fatty liver disease, and metabolic syndrome. Although most of the diagnostic and therapeutic approaches over the past several decades have focused on amyloid-beta (Aβ42) and aberrantly phosphorylated tau, which could be caused by consequences of brain insulin resistance, the broader array of pathologies including white matter atrophy with loss of myelinated fibrils and leukoaraiosis, non-Aβ42 microvascular disease, dysregulated lipid metabolism, mitochondrial dysfunction, astrocytic gliosis, neuro-inflammation, and loss of synapses vis-à-vis growth of dystrophic neurites, is not readily accounted for by Aβ42 accumulations, but could be explained by dysregulated insulin/IGF-1 signaling with attendant impairments in signal transduction and gene expression...

Cerebrovascular diseases are one of the most common causes of secondary movement disorders. Hypokinetic or hyperkinetic movement disorders may occur after an ischemic or hemorrhagic stroke, either immediately or thereafter. Such disorders are also known to be caused by diffuse leukoaraiosis, vascular malformations and dural fistulas in the basal ganglia or other brain regions. Area covered: The aim of this review was to describe movement disorders secondary to cerebrovascular diseases, and highlight their pivotal pathophysiological aspects, clinical features, diagnostic criteria and therapeutic options...

BACKGROUND: Cerebral small vessel disease (SVD) is characterised by progressive white matter hyperintensities (WMH), cognitive decline and loss of functional independence. The correspondence between neuroimaging findings and the severity of clinical symptoms has been modest, however, and thus the outcome may be affected by various host factors. We investigated the predictive value of educational and occupational attainments as proxy measures of cognitive reserve on long-term cognitive and functional outcome in patients with different degrees of WMH...

The role of the cerebral microbleeds (CMB) as a potential predictor of hemorrhagic complications of thrombolytic therapy is discussed. CMB are small perivascular hemosiderin deposits in the brain detected by magnetic resonance imaging in gradient echo T2* or SWI sequences. They are associated (along with leukoaraiosis or lacunes) with cerebral microangiopathies. Most often CMB are associated with hypertensive arteriopathy (the main cause of CMB localization) or cerebral amyloid angiopathy (the main cause of cerebral CMB)...

REVIEW
Mark R Etherton, Ona Wu, Natalia S Rost
Leukoaraiosis, a radiographic marker of cerebral small vessel disease detected on T2-weighted brain magnetic resonance imaging (MRI) as white matter hyperintensity (WMH), is a key contributor to the risk and severity of acute cerebral ischemia. Prior investigations have emphasized the pathophysiology of WMH development and progression; however, more recently, an association between WMH burden and functional outcomes after stroke has emerged. There is growing evidence that WMH represents macroscopic injury to the white matter and that the extent of WMH burden on MRI influences functional recovery in multiple domains following acute ischemic stroke (AIS)...

Endothelial dysfunction (ED), in particular cerebral ED, may be an essential biomarker for ischaemic cerebrovascular disease. However, there is no consensus on methods to best estimate cerebral ED. In this systematic review, we evaluate the use of l-arginine and N(G) -monomethyl-l-arginine (l-NMMA) for assessment of cerebral ED. A systematic search of PubMed, EMBASE and the Cochrane Library was done. We included studies investigating cerebrovascular response to l-arginine or l-NMMA in human subjects with vascular risk factors or ischaemic cerebrovascular disease...

The administration of thrombolytic therapy in elderly patients with dementia and acute ischemic stroke may be controversial, because the reported risk of rt-PA associated intracerebral hemorrhage in these patients is higher compared with that of patients without dementia and because these patients are already disabled. Moreover, there are known risk factors for hemorrhagic transformation in patients with dementia: amyloid angiopathy, leukoaraiosis and the presence of microbleeds. In this review, we describe the impact of dementia on functional outcome following thrombolytic therapy for acute ischemic stroke and discuss some of the issues related to the use of this therapy in this specific patient's population...
