Stroke-prone spontaneously hypertensive rats (SHRSP) on high-salt diet are characterized by extremely high arterial pressures, and have been endorsed as a model for hypertensive small vessel disease and vascular cognitive impairment. However, rapidly developing malignant hypertension is a well-known cause of posterior reversible encephalopathy syndrome (PRES) in humans, associated with acute neurological deficits, seizures, vasogenic cerebral edema and microhemorrhages. In this study, we aimed to examine the overlap between human PRES and SHRSP on high-salt diet...

Multiple intrinsic and extrinsic mechanisms contribute to vulnerability of cognitive decline and nurses play a significant role in assisting individuals and families to use strategies for healthy cognitive aging. The objective of this narrative review is to provide a synthesis of the intrinsic and extrinsic mechanisms of cognitive decline and conditions that are associated with cognitive decline. Well-established intrinsic mechanisms of cognitive decline include aging, apolipoprotein E (APOE) ε4 carrier status, SORL1 mutations, neuroinflammation, mitochondrial dysfunction, amyloid deposition, and demyelination...

BACKGROUND: Various techniques have been employed for the early detection of perioperative cerebral ischaemia and hypoxia. Cerebral near-infrared spectroscopy (NIRS) is increasingly used in this clinical scenario to monitor brain oxygenation. However, it is unknown whether perioperative cerebral NIRS monitoring and the subsequent treatment strategies are of benefit to patients. OBJECTIVES: To assess the effects of perioperative cerebral NIRS monitoring and corresponding treatment strategies in adults and children, compared with blinded or no cerebral oxygenation monitoring, or cerebral oxygenation monitoring based on non-NIRS technologies, on the detection of cerebral oxygen desaturation events (CDEs), neurological outcomes, non-neurological outcomes and socioeconomic impact (including cost of hospitalization and length of hospital stay)...

BACKGROUND: Stroke is associated with an increased risk of dementia; however, the impact of stroke on cognition has been found to be variable, such that stroke survivors can show decline, remain stable, or revert to baseline cognitive functioning. Knowing the natural history of cognitive impairment after stroke is important for intervention. The aim of this systematic review is to investigate the longitudinal course of cognitive function in stroke survivors. METHODS AND RESULTS: Three electronic databases (Medline, Embase, PsycINFO) were searched using OvidSP from inception to July 15, 2016...

The risk of developing dementia is increased in patients with atrial fibrillation (AF), with the incidence of both conditions increasing with aging. Patients with dementia frequently do not receiving adequate thrombo-prophylaxis, because of the inability to monitor INR and/or to achieve and maintain good compliance with anticoagulant treatment. Under-treatment is therefore an important contributor to the increased risk of ischemic stroke and mortality in this subgroup of AF patients. In newly-diagnosed patients with AF starting oral anticoagulation, the presence of cognitive impairment should be considered in addition to the calculation of the SAMe-TT2R2 score, as part of an integrated decision management pathway to choose the most appropriate oral anticoagulant [i...

Cognitive impairment is common in patients with hypertension. Left ventricular hypertrophy (LVH) is recognised as a marker of hypertension-related organ damage and is a strong predictor of coronary artery disease, heart failure and stroke. There is evidence that LVH is independently associated with cognitive impairment, even after adjustment for the presence of hypertension. We conducted a systematic review that examined cognitive impairment in adults with LVH. Independent searches were performed in Ovid MEDLINE, Ovid psycInfo and PubMed with the terms left ventricular hypertrophy and cognition...

PURPOSE: Whether intermittent fasting (IF) treatment after stroke can prevent its long-term detrimental effects remains unknown. Here, we investigate the effects of postoperative IF on cognitive deficits and its underlying mechanisms in a permanent two-vessel occlusion (2VO) vascular dementia rat model. METHODS: Rats were subjected to either IF or ad libitum feeding 1 week after 2VO surgery. The cognition of rats was assessed using the novel object recognition (NOR) task and Morris water maze (MWM) 8 weeks after surgery...

INTRODUCTION: Stroke is one of the primary causes of death and disability worldwide, leaving a considerable proportion of survivors with persistent cognitive and functional deficits. Despite the prevalence of poststroke cognitive impairment, there is no established treatment aimed at improving cognitive function following a stroke. Therefore, the aims of this systematic review are to identify psychological interventions intended to improve poststroke cognitive function and establish their efficacy...

INTRODUCTION: There is little control of cardiovascular (CV) risk factors in secondary prevention after an ischaemic stroke, in part due to a lack of adherence to treatment. The CV polypill may contribute to proper treatment adherence, which is necessary for CV disease prevention. This study aimed to establish how and in what cases the CV polypill should be administered. METHODS: A group of 8 neurologists drafted consensus recommendations using structured brainstorming and based on their experience and a literature review...

BACKGROUND: Recent studies of functional or effective connectivity in the brain have reported that motor-related brain regions were activated during motor execution and motor imagery, but the relationship between motor and cognitive areas has not yet been completely understood. The objectives of our study were to analyze the effective connectivity between motor and cognitive networks in order to define network dynamics during motor execution and motor imagery in healthy individuals. Second, we analyzed the differences in effective connectivity between correct and incorrect responses during motor execution and imagery using dynamic causal modeling (DCM) of electroencephalography (EEG) data...

BACKGROUND AND PURPOSE: Walking in the community is an important aspect of independence and quality of life (QOL) that poses challenges for individuals with stroke. This study investigated whether performance on the Functional Gait Assessment (FGA) differentiated spatiotemporal gait parameters, QOL, and fall history of community-ambulating individuals with stroke. We hypothesized that those scoring higher on the FGA would present with better gait speed and cadence, stride width and length, and improved load time on the paretic limb, report a higher QOL, and be less likely to have a fall history than those who scored lower on the FGA...

Background Stroke is the leading cause of severe disability and many survivors report long-term physical or cognitive impairments that may impact their ability to achieve community mobility (CM). PURPOSE: To determine the extent to which people with chronic stroke achieve CM compared to age-matched norms or non-neurologically impaired controls. Methods The StrokEDGE outcome measures were searched to identify validated tools that included >25% of items addressing CM. MEDLINE, CINAHL, Google Scholar, PubMed, PEDro and the Cochrane databases were searched from 2001 to 2015 with the identified outcome measures cross-referenced against search terms related to stroke and CM...
