Domain-specific characterisation of early cognitive impairment following spontaneous intracerebral haemorrhage.

2018

Cognitive deficits after spontaneous intracerebral haemorrhage (ICH) are common and result in functional impairment, but few studies have examined deficits across cognitive domains in the subacute phase. This study aims to describe the cognitive profile following acute ICH and explore how cerebral amyloid angiopathy (CAA) may impact performance. We retrospectively reviewed 187 consecutive patients with ICH (mean age 58.9 years, 55.6% male) with available imaging and neuropsychological data (median 12 days after stroke). In our cohort, 84% (n = 158) were impaired in at least one cognitive domain and 65% (n = 122) in two or more domains. Deficits in non-verbal IQ (76.6%), information processi…

Regulatory effects of simvastatin and apoJ on APP processing and amyloid-beta clearance in blood-brain barrier endothelial cells

2017

Amyloid-β peptides (Aβ) accumulate in cerebral capillaries indicating a central role of the blood-brain barrier (BBB) in the pathogenesis of Alzheimer’s disease (AD). Although a relationship between apolipoprotein-, cholesterol- and Aβ metabolism is evident, the interconnecting mechanisms operating in brain capillary endothelial cells (BCEC) are poorly understood. ApoJ (clusterin) is present in HDL that regulates cholesterol metabolism which is disturbed in AD. ApoJ levels are increased in AD brains and in plasma of cerebral amyloid angiopathy (CAA) patients. ApoJ may bind, prevent fibrillization, and enhance clearance of Aβ. We here define a connection of apoJ and cellular cholesterol home…

Transient Focal Neurological Events in Cerebral Amyloid Angiopathy and the Long-term Risk of Intracerebral Hemorrhage and Death: A Systematic Review …

2021

Importance Transient focal neurological episodes (TFNEs) are a frequently overlooked presentation of cerebral amyloid angiopathy (CAA), a condition with prognostic implications that are still not well described. Objective To perform a systematic review and meta-analysis to examine the factors associated with incident lobar intracerebral hemorrhage (ICH) and death in patients with CAA presenting with TFNEs. Data Sources A systematic review and individual participant meta-analysis including (1) a hospital-based cohort and (2) the results obtained from a systematic search performed in MEDLINE and Embase completed in December 2019. Study Selection Included studies were observational reports of …

Prevalence and Cognitive Impact of Medial Temporal Atrophy in a Hospital Stroke Service: Retrospective Cohort Study

2015

Background Cerebrovascular disease and neurodegeneration cause cognitive impairment and frequently coexist. Aims Our objectives were to investigate the prevalence and cognitive impact of medial temporal lobe atrophy – a radiological marker often associated with Alzheimer's disease – in a hospital stroke service. Methods Retrospective cohort study of patients from a hospital stroke service. Patients assessed for suspected ischemic stroke or transient ischemic attack, irrespective of final diagnosis, underwent neuropsychological testing and magnetic resonance imaging. medial temporal lobe atrophy, white matter hyperintensities, lacunes, and cerebral microbleeds were rated using established cr…

Cerebral microbleeds and vascular cognitive impairment

2010

Abstract MRI manifestations of small vessel diseases including white matter hyperintensities and lacunes have been recognized as potential substrates of vascular cognitive impairment for many years. Cerebral microbleeds (CMBs) – small, perviascular haemorrhages seen as small, well-demarcated, hypointense, rounded lesions on MRI sequences sensitive to magnetic susceptibility effects – are also now recognized as an imaging marker for small vessel pathology, but their clinical impact on cognition remains uncertain. CMBs are present in about a third of patients with ischaemic stroke, and in a high proportion of patients with Alzheimer's disease, cerebral amyloid angiopathy, and vascular dementi…

Radiographic Features with Pathological Correlation in Cerebral Amyloid Inflammatory Vasculopathy A Case Report

2014

Cerebral Amyloid Angiopathy (CAA) is characterized by deposit of β-amyloid protein in the cortical and leptomeningeal arteries. It tends to increase in prevalence with advancing age and seems to have slight predilection for temporal, parietal and occipital lobes. It has recently been identified an inflammatory form of this angiophaty. This report describes a case presenting as an inflammatory vasculitis-perivasculitis form successfully treated with steroids and discuss about typical features and findings of this condition.
