Conclusions: Mechanical thrombectomy for anterior circulation strokes based on CTP did not result in a significant functional outcome improvement. The duration of the thrombectomy procedure was the sole time-interval related to improved functional outcome. Published on 2020-01-20 12:01:10

AbstractPurpose of the ReviewWith no disease-modifying treatments for Alzheimer ’s disease (AD) currently established, a priority for public health is prevention of cognitive decline and dementia. Treatment and prevention of cardiovascular disease (CVD) may provide such an opportunity.Recent FindingsWhile the pathology of athero- and arteriolosclerotic cerebrovascular disease was once thought of as distinct from AD pathobiology, accumulating evidence suggests that there is more overlap in vascular and AD-related pathologies than previously recognized. CVD and its risk factors are associated with cognitive decline and...

Semin Neurol DOI: 10.1055/s-0039-3402737Isolated dizziness and vertigo due to vascular mechanisms are frequently misdiagnosed as peripheral vestibulopathy or vestibular migraine. For diagnosis of strokes presenting with an acute prolonged (≥ 24 hours) vestibular syndrome, findings on clinical examination, such as HINTS (negative head impulse tests, detection of direction-changing gaze-evoked nystagmus, and presence of skew deviation), are more sensitive than findings on neuroimaging. Since HINTS alone cannot securely detect anterior inferior cerebellar artery strokes, additional attention should be paid to the pa...

Abstract Atrial fibrillation (AF) is the most common type of arrhythmia, which undermines cardiac function. Atrial fibrillation is a multi-facet malady and it may occur as a result of other diseases or it may trigger other problems. One of the main complications of AF is stroke due to the possibility of clot formation inside the atrium. However, the possibility of stroke occurrence due to the AF and the location from which an embolus dispatches are subject of debate. Another hypothesis about the embolus formation during AF is thrombus formation in aorta and carotid arteries, embolus detachment and its movement. To...

Authors: Sheen JJ, Kim YW Abstract Three randomized control trials (RCTs), published in 2013, investigated efficacy of mechanical thrombectomy in large vessel occlusions and did not show better results compared to intravenous (IV) recombinant tissue-type plasminogen activator (tPA) alone. However, most clinicians treating stroke consider mechanical thrombectomy as the standard treatment rather than using IV tPA alone. This paradigm shift was based on five RCTs investigating efficacy of mechanical thrombectomy in acute ischemic stroke conducted from 2010 to 2015. They demonstrated that mechanical thrombectomy was ef...

AbstractBackgroundPatients with atrial fibrillation (AF) and dementia experience reduced quality of life and increased mortality. Technetium 99m ECD brain perfusion single-photon emission computed tomography (99mTc-ECD brain perfusion SPECT) is a beneficial modality for diagnosing dementia and identifying high-risk patients with mild cognitive impairment. The aim of this study was to evaluate the prognostic value of brain perfusion using99mTc-ECD SPECT in patients with AF and dementia.MethodsOf a total of 405 consecutive patients diagnosed with AF as cardiac outpatients with dementia using the Mini-Mental State Examination...

CONCLUSIONS: The collateral-based imaging paradigm using multiphase CTA compares well with CTP in selecting patients for endovascular thrombectomy in the late time window.

Conclusions: There is no justification for the use of reperfusion procedures in acute ischaemic stroke in the anterior circulation in patients with initially unfavourable multimodal computed tomography scores. PMID: 31908703 [PubMed]

Low-dose aspirin reduces the frequency of adverse vascular events in those at increased risk of occlusive cardiovascular disease (CVD). People who benefit include those: with a history of myocardial infarction, ischaemic stroke, unstable or stable angina, peripheral arterial disease, or atrial fibrillation (1). The pathophysiology of CVD risk contributes to cognitive decline through multiple pathways that include cerebral hypo-perfusion, hypoxia, hippocampal atrophy, emboli, or infarcts (2,3). However, the value of aspirin use in prevention of cognitive impairment remains uncertain since results relating to the influence o...
