Study: 'mini strokes should be treated immediately with aspirin'
Conclusion The study supports current recommended practice that people with a TIA or ischaemic stroke caused by a blood clot are treated with aspirin as soon as possible. NHS experts are considering whether to recommend that you take aspirin yourself while waiting for medical help. The reason this isn't recommended at present is that some people will have had a haemorrhagic (bleeding) stroke, and aspirin can make the bleeding worse. For people who've had a full stroke, an urgent brain scan is usually performed to exclude bleeding as a cause and check it's safe to proceed with anti-clotting treatment. The risk of trans...

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...

Risk of aspirin-related bleeding is higher in the over-75s
Conclusion This valuable cohort study helps to quantify the extent of bleeding risk in people taking aspirin for secondary prevention of cardiovascular disease. Aspirin is well known to carry bleeding risk – particularly in older adults – but this study suggests the risk may be higher than previously thought. The researchers say that for adults under the age of 75, the annual bleeding risk at around 1% is similar to that suggested by previous trials, as is the ratio of bleeds to the number of cardiovascular events. However, this risk increases for older adults, especially for major bleeds of the stomach and upper diges...

Fruit may be good for you, but don’t ditch the statins
Conclusion The study adds to evidence that fresh fruit is likely to be good for our cardiovascular health, although we can't be sure from this study that it definitely prevents deaths, heart attacks or strokes. Observational studies cannot prove that one factor causes another, even when they are as big as this study, because other unmeasured factors could be responsible for the results. In this case, a major potential confounder that the researchers failed to take into account was whether the participants were taking any medication – they only excluded people taking blood pressure tablets. The link with statins, made by ...

Vertigo and Dizziness in Anterior Circulation Cerebrovascular Disease: A Systematic Review (P3.092)
CONCLUSIONS: Vertigo and dizziness are not rare manifestations of carotid territory ischemia, particularly in the temporo-parietal regions. Although dizziness is generally more prevalent in women, anterior circulation stroke causing dizziness appears to be more prevalent in men. Clinicians should carefully consider a search for anterior circulation vascular disease in patients presenting with vestibular symptoms.Disclosure: Dr. Zhou has nothing to disclose.

Statins are 'safe, effective and should be used more widely'
Conclusion This study reviews evidence from randomised controlled trials (RCTs) and observational studies to better evaluate the effects and safety of statin therapy. It provides valuable data on the size of the benefits compared with the risks, informing a topic that has had much media coverage in recent times. The researchers highlight that the benefits of statin therapy for people at risk of cardiovascular disease events far outweigh any possible side effects. But it is still for a doctor and their patient to come to a conclusion about what the best treatment for them may be. If you have been prescribed a statin, it...

Functional MRI of Letter Cancellation Task Performance in Older Adults
Conclusion The present work is the first to identify neural correlates of the LCT using fMRI and tablet technology in a healthy aging population. Across all ages, the activation was found to be bilateral, including in the cerebellum, superior temporal lobe, precentral gyrus, frontal gyrus, and various occipital and parietal areas. With increasing age, performance generally decreased and brain activity was reduced in the supplementary motor area, middle and inferior frontal gyrus, middle occipital gyrus, putamen and cerebellum. Better LCT performance was correlated with increased activity in the middle frontal gyrus, and r...

High-dose painkiller heart risk: small but significant
Conclusion This large review adds to, and expands on, the current evidence on the risks of vascular disease and gastrointestinal complications for different NSAIDs. It largely concentrates on trials of high doses of NSAIDs that can only be prescribed by a doctor. It is unclear from this study whether there is any risk from taking lower doses available over the counter. While most experts advise that low-dose NSAIDs, taken occasionally, are safe for most people, an accompanying editorial points out that there are still “large gaps” in evidence on the risks with lower doses of NSAIDs. While the risk to individuals is sma...

Glyn Humphreys obituary
Key figure in cognitive neuroscience whose research helped many stroke victimsWhen the neuropsychologist Glyn Humphreys, who has died suddenly aged 61, took up his first lectureship, at Birkbeck College, London, a student with a background in physiotherapy joined his class. She asked about the implications of David Marr’s theory of visual perception for the understanding of patients who experience visual disturbances after suffering a stroke. This led to a lively discussion and a subsequent visit to a stroke clinic. It proved to be a turning point in Glyn’s research, highlighting the many ways in which brain damage can...

Risk-benefit profile of statin therapy 'may be more positive than expected'
This study showed that providing an effective low-cost statin therapy to 10,000 patients for five years would prevent major cardiovascular events such as heart attacks, strokes and coronary artery bypasses in 1,000 people with preexisting vascular disease, as well as 500 people who are at increased risk but have not yet had a vascular event. By contrast, only 50 to 100 cases of symptomatic adverse events would be expected over the same period, as well as 50 to 100 new cases of diabetes, five cases of myopathy and between five and ten haemorrhagic strokes. Should statins be more widely used? Currently, about six million peo...

Statins side effects 'have been overstated,' says study
Conclusion This is a complex study that provides a plausible explanation for the difference in reports of adverse effects of statins in RCTs and observational studies, some of which have suggested as many as 1 in 5 people get side effects from statins. However, we need to be aware of some limitations and unanswered questions: When people knew they were taking statins, they were more likely to report muscle pain than those not taking statins. But they were less likely to report muscle pain than in the first phase of the study, when they didn't know whether they were taking statins or placebo. We don't know why this is. ...

Benefits of Motor Imagery for Human Space Flight: A Brief Review of Current Knowledge and Future Applications
Conclusion: How to Implement MI Into the Preparation and Mission of the Astronauts Motor imagery should ideally be performed before, during, and after exposure to microgravity to prepare for the lack of gravity, counteract the effects of weightlessness and promote the re-adaptation to normogravity. A quite similar theoretical viewpoint had been nicely proposed by Bock et al. (2015), who more specifically focused on the preparation period few days before landing. These authors developed two phases of individual MI training program to reach an optimal level of preparation before exposure to microgravity. In the first phase,...

Age Is a Greater Influence on Small Saccades Than Target Size in Normal Subjects on the Horizontal Video Head Impulse Test
Conclusion: While this study suggests that target size may have a statistically significant impact on the vHIT saccade profile of normal subjects, age has a greater influence on the incidence and size of small vHIT saccades. Introduction The video head impulse test (vHIT) is a quantitative adaptation of the clinical head impulse test (1), and enables functional assessment of the high-frequency angular vestibulo-ocular reflex (VOR) in all three planes of head rotation (2, 3). Lightweight goggles worn by the subject detect head movement using an accelerometer and gyroscope, and a high frame rate video camera tracks eye...

Ability of brain to protect itself from damage revealed
(University of Oxford) The origin of an innate ability the brain has to protect itself from damage that occurs in stroke has been explained for the first time. The Oxford University researchers hope that harnessing this inbuilt biological mechanism, identified in rats, could help in treating stroke and preventing other neurodegenerative diseases in the future.
