Abstract
Sporadic cerebral amyloid angiopathy is a common, well-defined small vessel disease and a largely untreatable cause of intracerebral haemorrhage and contributor to age-related cognitive decline. The term 'cerebral amyloid angiopathy' now encompasses not only a specific cerebrovascular pathological finding, but also different clinical syndromes (both acute and progressive), brain parenchymal lesions seen on neuroimaging and a set of diagnostic criteria-the Boston criteria, which have resulted in increasingly detected disease during life. Over the past few years, it has become clear that, at the pathophysiological level, cerebral amyloid angiopathy appears to be in part a protein elimination failure angiopathy and that this dysfunction is a feed-forward process, which potentially leads to worsening vascular amyloid-β accumulation, activation of vascular injury pathways and impaired vascular physiology. From a clinical standpoint, cerebral amyloid angiopathy is characterized by individual focal lesions (microbleeds, cortical superficial siderosis, microinfarcts) and large-scale alterations (white matter hyperintensities, structural connectivity, cortical thickness), both cortical and subcortical. This review provides an interdisciplinary critical outlook on various emerging and changing concepts in the field, illustrating mechanisms associated with amyloid cerebrovascular pathology and neurological dysfunction.

Remote Intracerebral Hemorrhage After Intravenous Thrombolysis. Stroke 2016; 47:2003-9.

Abstract
Background and Purpose—
Remote parenchymal hemorrhage (rPH) after intravenous thrombolysis with recombinant tissue-type plasminogen activator may be associated with cerebral amyloid angiopathy, although supportive data are limited. We aimed to investigate risk factors of rPH after intravenous thrombolysis with recombinant tissue-type plasminogen activator.
Methods—
This is an observational study of patients with ischemic stroke who were treated with intravenous thrombolysis with recombinant tissue-type plasminogen activator and were included in a multicenter prospective registry. rPH was defined as any extraischemic hemorrhage detected in the follow-up computed tomography. We collected demographic, clinical, laboratory, radiological, and outcome variables. In the subset of patients who underwent a magnetic resonance imaging examination, we evaluated the distribution and burden of cerebral microbleeds, cortical superficial siderosis, leukoaraiosis, and recent silent ischemia in regions anatomically unrelated to the ischemic lesion that caused the initial symptoms. We compared patients with rPH with those without rPH or parenchymal hemorrhage. Independent risk factors for rPH were obtained by multivariable logistic regression analyses.
Results—
We evaluated 992 patients (mean age, 74.0±12.6 years; 52.9% were men), and 408 (41%) of them underwent a magnetic resonance imaging. Twenty-six patients (2.6%) had a rPH, 8 (0.8%) had both rPH and PH, 58 (5.8%) had PH, and 900 (90.7%) had no bleeding complication. Lobar cerebral microbleeds (odds ratio, 8.0; 95% confidence interval, 2.3–27.2) and recent silent ischemia (odds ratio, 4.8; 95% confidence interval, 1.6–14.1) increased the risk of rPH.
Conclusions—
The occurrence of rPH after intravenous thrombolysis with recombinant tissue-type plasminogen activator in patients with ischemic stroke is associated with lobar cerebral microbleeds and multiple ischemic lesions in different regions.
