Systematic Review and Meta-Analysis of Interventions Tested in Animal Models of Lacunar Stroke Basic Sciences
Conclusions— No intervention has yet been tested in sufficient range and depth to support translation to clinical trial. There is limited reporting of measures to reduce the risk of bias and evidence for a substantial publications bias.

Stroke and Neurodegeneration Induce Different Connectivity Aberrations in the Insula Brief Reports
Conclusions— Functional insular cortex connectivity is affected differently by cerebral ischemia and neurodegeneration, possibly because of differences in the cause-specific pathophysiological mechanisms of each disease. These findings have important clinical and theoretical implications.

Progressive Cognitive Deficits in a Mouse Model of Recurrent Photothrombotic Stroke Brief Reports
Conclusions— Our results show progressive cognitive deficits in a mouse model of recurrent photothrombotic stroke. The presented model resembles the clinical features of human multi-infarct dementia and enables the investigation of its pathophysiological mechanisms and the evaluation of treatment strategies.

Methodological Factors in Determining Risk of Dementia After Transient Ischemic Attack and Stroke: (II) Effect of Attrition on Follow-Up Clinical Sciences
Conclusions— Exclusion of patients unavailable for clinic follow-up reduces the measured risk of postevent dementia. Use of multiple follow-up methods, including home visits, telephone assessments, and consent, to access primary care records substantially increases ascertainment of longer-term dementia outcomes.

Genetic Study of White Matter Integrity in UK Biobank (N=8448) and the Overlap With Stroke, Depression, and Dementia Clinical Sciences
Conclusions—Genetic variants within the VCAN gene may play a role in the mechanisms underlying microstructural integrity of the white matter in the brain measured as FA and MD. Mechanisms underlying white matter alterations are shared with cerebrovascular disease, and inherited differences in white matter microstructure impact on Alzheimer disease and major depressive disorder.

Poststroke dementia is associated with recurrent ischaemic stroke
Conclusions Poststroke dementia predicts recurrence of ischaemic stroke in long-term follow-up and should be considered when estimating prognosis.

Baseline Cognitive Function, Recurrent Stroke, and Risk of Dementia in Patients With Stroke Clinical Sciences
Conclusions— Patients with stroke with low MMSE scores are at high risk of dementia over time, even in the absence of a recurrent stroke, and should therefore be followed closely for further cognitive decline.

Importance of Considering Competing Risks in Time-to-Event Analyses: Application to Stroke Risk in a Retrospective Cohort Study of Elderly Patients With Atrial Fibrillation Original Articles
Conclusions: The incidence of death without stroke was 9-fold higher than that of stroke, leading to biased estimates of stroke risk with traditional time-to-event methods. Statistical methods that appropriately account for competing risks should be used to mitigate this bias.

Diet Beverages Linked To Increased Stroke Risk & Heart Attacks
This study, as well as other research on the connection between diet beverages and vascular disease, is observational and cannot show cause and effect. That’s a major limitation, researchers say, as it’s impossible to determine whether the association is due to a specific artificial sweetener, a type of beverage or another hidden health issue. “Postmenopausal women tend to have higher risk for vascular disease because they are lacking the protective effects of natural hormones,” North Carolina cardiologist Dr. Kevin Campbell said, which could contribute to increased risk for heart disease and stroke...

Cognitive impairment after lacunar stroke: systematic review and meta-analysis of incidence, prevalence and comparison with other stroke subtypes
Background Cognitive impairment and dementia are common after stroke. It is unclear if risk differs between ischaemic stroke subtypes. Lacunar strokes might be less likely to affect cognition than more severe, larger cortical strokes, except that lacunar strokes are associated with cerebral small vessel disease (SVD), which is the commonest vascular cause of dementia. Methods We searched MEDLINE and PsychINFO for studies of mild cognitive impairment (MCI) or dementia after lacunar or cortical ischaemic stroke. We calculated the OR for cognitive impairment/dementia in lacunar versus non-lacunar stroke, and their incidence ...

ICARUSS, the Integrated Care for the Reduction of Secondary Stroke trial: rationale and design of a randomized controlled trial of a multimodal intervention to prevent recurrent stroke in patients with a recent cerebrovascular event, ACTRN = 12611000264987
ConclusionThe ICARUSS study aims to recruit and follow up patients between 2007 and 2013 and demonstrate the effectiveness of exposure to the ICARUSS model in stroke survivors to reduce recurrent stroke or vascular events and promote the implementation of best practice risk factor management at primary care level.

Does the Influence of Stroke on Dementia Vary by Different Levels of Prestroke Cognitive Functioning?: A Cohort Study Clinical Sciences
Conclusions— Stroke and prestroke cognition were independently associated with increased probability of poststroke dementia. Stroke results in disproportionate increase in the risk of dementia when premorbid cognitive functioning is high.

Prevention of Stroke in Patients With Silent Cerebrovascular Disease: A Scientific Statement for Healthcare Professionals From the American Heart Association/American Stroke Association AHA/ASA Scientific Statement
Two decades of epidemiological research shows that silent cerebrovascular disease is common and is associated with future risk for stroke and dementia. It is the most common incidental finding on brain scans. To summarize evidence on the diagnosis and management of silent cerebrovascular disease to prevent stroke, the Stroke Council of the American Heart Association convened a writing committee to evaluate existing evidence, to discuss clinical considerations, and to offer suggestions for future research on stroke prevention in patients with 3 cardinal manifestations of silent cerebrovascular disease: silent brain infarcts...
