INTRODUCTION: Despite recent advances in the management of acute stroke, fewer than 10% of patients receive reperfusion therapy. One of the main reasons for such a low rate of administration is the delay on the part of patients and their families in seeking medical attention. This study aimed to analyse this delay. METHODS: A prospective observational study was conducted on consecutive stroke or transient ischaemic attack. Data on sociodemographic and clinical parameters, decision delay, pre-hospital delay, and first medical contact were collected...

Vascular dementia (VaD) is widely recognised as the second most common type of dementia. Consensus and accurate diagnosis of clinically suspected VaD relies on wide-ranging clinical, neuropsychological and neuroimaging measures in life but more importantly pathological confirmation. Factors defining subtypes of VaD include the nature and extent of vascular pathologies, degree of involvement of extra and intracranial vessels and the anatomical location of tissue changes as well as time after the initial vascular event...

Cerebral small vessel disease (CSVD) occurs often in memory clinic patients. Apart from cognitive deficits, these patients can express physical decline, which predicts adverse health outcomes. In this study, we investigated the cooccurrence of clinically relevant impairments in physical performance and CSVD in memory clinic patients. We included 131 patients with vascular brain injury, mild cognitive impairment or Alzheimer disease with available 3T MRI and physical performance scores. CSVD was visually rated according to 3 subtypes and as a total burden score, composed of the presence of white matter hyperintensities (WMH), lacunar infarcts (LI), and cerebral microbleeds (MB)...

BACKGROUND: There is emerging interest in the relationship between neuroimaging location of lacunar infarcts and underlying stroke risk factors. Recent methods used for localization of lacunar infarcts are affected by high inter-rater variability. We used a novel algorithm-driven method that provided quantitative assessment of the distance of the lacunar infarct from the origins of the lenticulostriate arteries. METHODS: We conducted a retrospective analysis of patients who presented with lacunar infarcts between 2007 and 2011...

Advances in neuroimaging have enabled greater understanding of the progression of cerebral degenerative processes associated with ageing-related dementias. Leukoaraiosis or rarefied white matter (WM) originally described on computed tomography is one of the most prominent changes which occurs in older age. White matter hyperintensities (WMH) evident on magnetic resonance imaging have become commonplace to describe WM changes in relation to cognitive dysfunction, types of stroke injury, cerebral small vessel disease and neurodegenerative disorders including Alzheimer's disease...

CLINICAL PROBLEM: Intracerebral cysts are common findings in imaging of the neurocranium and are not always clinically significant. The pathological spectrum of intracerebral cysts is, however, very broad and in addition to incidental findings includes developmental disorders, malformation tumors, primary and secondary neoplasms and infectious etiologies, such as cerebral abscess formation, cysticercosis or residuals after congenital cytomegalovirus infections. Intracerebral cystic defects may be caused by inflammatory central nervous system (CNS) diseases, such as multiple sclerosis as well as by mitochondriopathies, leukodystrophy, electrolyte disturbances or osmotic demyelination syndrome or brain infarctions, e...

BACKGROUND AND AIMS: Enlarged basal ganglia perivascular spaces (BG-PVS) are a marker of cerebral small vessel disease (SVD). The association between enlarged BG-PVS and atherosclerosis has been explored, but knowledge is limited to extracranial vessels. We aimed to assess whether enlarged BG-PVS correlate with carotid siphon calcifications (CSC), used as a surrogate of intracranial atherosclerosis. METHODS: Atahualpa residents aged ≥60 years underwent head computed tomography (CT) for assessment of CSC, and brain magnetic resonance imaging (MRI) for evaluation of BG-PVS and other imaging markers of SVD...
