Cerebral Amyloid

Amyloid angiopathy–associated intracerebral hemorrhage (ICH) comprises 12%–15% of lobar ICH in the elderly. This growing population has an increasing incidence of thrombolysis-related hemorrhages, causing the management of hemorrhages associated with cerebral amyloid angiopathy (CAA) to take center stage. A concise reference assimilating the pathology and management of this clinical entity does not exist. Amyloid angiopathy–associated hemorrhages are most often solitary, but the natural history often progresses to include multifocal and recurrent hemorrhages. Compared with other causes of ICH, patients with CAA-associated hemorrhages have a lower mortality rate but an increased risk of recurrence. Unlike hypertensive arteriolar hemorrhages that occur in penetrating subcortical vessels, CAA-associated hemorrhages are superficial in location due to preferential involvement of vessels in the cerebral cortex and meninges. This feature makes CAA-associated hemorrhages easier to access surgically. In this paper, the authors discuss 3 postulates regarding the pathogenesis of amyloid hemorrhages, as well as the established clinicopathological classification of amyloid angiopathy and CAA-associated ICH. Common inheritance patterns of familial CAA with hemorrhagic strokes are discussed along with the role of genetic screening in relatives of patients with CAA. The radiological characteristics of CAA are described with specific attention to CAA-associated microhemorrhages. The detection of these microhemorrhages may have important clinical implications on the administration of anticoagulation and antiplatelet therapy in patients with probable CAA. Poor patient outcome in CAA-associated ICH is associated with dementia, increasing age, hematoma volume and location, initial Glasgow Coma Scale score, and intraventricular extension. The surgical management strategies for amyloid hemorrhages are discussed with a review of published surgical case series and their outcomes with a special attention to postoperative hemorrhage.

Objectives: Intracerebral hemorrhage (ICH) patients with CT angiography (CTA) spot sign are at increased risk of hematoma expansion and poor outcome. Since ICH is often the acute manifestation of a chronic cerebral vasculopathy, we investigated whether different clinical or imaging characteristics predict spot sign presence in patients with different underlying vasculopathies. Using ICH location as a surrogate for hypertension-related ICH and cerebral amyloid angiopathy-related ICH, we identified risk factors associated with spot sign. METHODS: We retrospectively analyzed a prospective cohort of consecutive spontaneous ICH patients with available CTA. Spot sign presence was ascertained by two independent readers blinded to clinical data. We assessed potential predictors of spot sign be performing uni- and multivariable logistic regression, analyzing deep and lobar ICH separately. RESULTS: 649 patients were eligible, 291 (45%) deep and 358 (55%) lobar ICH. Median time from symptom onset to CTA was 4.5 (IQR 5.2) and 5.7 (IQR 7.4) hours in patients with deep and lobar ICH, respectively. At least one spot sign was present in 76 (26%) deep and 103 (29%) lobar ICH patients. In mutivariable logistic regression, independent predictors of spot sign in deep ICH were warfarin (OR 2.82 [95%CI 1.06-7.57]; p=0.03), time from symptom onset to CTA (OR 0.9 [95%CI 0.81-0.97]; p=0.02), and baseline ICH volume (OR 1.27 [95%CI 1.14-1.43]; p=2.5E-5; per 10 mL increase). Predictors of spot sign in lobar ICH were preexisting dementia (OR 2.7 [95%CI 1.15-6.43]; p=0.02), warfarin (OR 4.01 [95%CI 1.78-9.29]; p=0.009), and baseline ICH volume (OR 1.27 [95%CI 1.17-1.39]; p=5.4E-8; per 10 mL increase). As expected, spot sign presence was a strong predictor of hematoma expansion in both deep (OR 3.52 [95%CI 1.72-7.2]; p=0.0005) and lobar ICH (OR 6.53 [95%CI 3.23-13.44]; p=2.2E-7). CONCLUSIONS: The most potent associations with spot sign are shared by deep and lobar ICH, suggesting that ICH caused by different vasculopathic processes share biological features. The relationship between preexisting dementia and spot sign in lobar ICH, but not deep ICH, suggests that ICH occurring in the context of more advanced cerebral amyloid angiopathy may be more likely to have prolonged bleeding.

Cerebral amyloid angiopathy is a common small vessel disease in the elderly involving vascular amyloid-β deposition. Cerebral amyloid angiopathy is one of the leading causes of intracerebral hemorrhage and a significant contributor to age-related cognitive decline. The awareness of a diagnosis of cerebral amyloid angiopathy is important in clinical practice as it impacts decisions to use lifelong anticoagulation or nonpharmacological alternatives to anticoagulation such as left atrial appendage closure in patients who have concurrent atrial fibrillation, another common condition in older adults. This review summarizes the latest literature regarding the management of patients with sporadic cerebral amyloid angiopathy, including diagnostic criteria, imaging biomarkers for cerebral amyloid angiopathy severity, and management strategies to decrease intracerebral hemorrhage risk. In a minority of patients, the presence of cerebral amyloid angiopathy triggers an autoimmune inflammatory reaction, referred to as cerebral amyloid angiopathy-related inflammation, which is often responsive to immunosuppressive treatment in the acute phase. Diagnosis and management of cerebral amyloid angiopathy-related inflammation will be presented separately. While there are currently no effective therapeutics available to cure or halt the progression of cerebral amyloid angiopathy, we discuss emerging avenues for potential future interventions.

Background: Cerebral amyloid angiopathy (CAA) is a common cause of cerebrovascular disease in the elderly. There is accumulating evidence suggestive of transmissibility of β-amyloid resulting in amyloid pathology at younger age. According to the Boston criteria, defining CAA in patients <55 years requires histological evidence which may hamper diagnosis. We explored the role of amyloid PET in the diagnosis of possible transmissible CAA in young adults. Cases: We report 4 young adults (<55 years) presenting with clinical and neuroimaging features suggestive of CAA but without genetic evidence of hereditary CAA explaining the young onset. A common factor in all cases was a medical history of neurosurgery during childhood. All patients underwent amyloid PET to support the diagnosis of an amyloid-related pathology and the result was positive in all 4. Conclusion: Combining the clinical presentation and imaging findings of the 4 cases, we postulate transmissible CAA as the possible diagnosis. Further epidemiological studies are required to gain more insight in the prevalence of this novel entity. Amyloid PET may be a useful, non-invasive tool in these analyses especially since pathological evidence will be lacking in most of these studies.

We report the case of long-term follow-up of brain magnetic imaging of cerebral amyloid angiopathy. Cerebral amyloid angiopathy is often considered a major cause of spontaneous intracerebral hemorrhage in the elderly. This case illustrates the markedly progressive clinical and radiological features of the vasculopathic process in 10 years.

Background and Purpose: The general cardiovascular Framingham risk score (FRS) identifies adults at increased risk for stroke. We tested the hypothesis that baseline FRS is associated with the presence of postmortem cerebrovascular disease (CVD) pathologies. Methods: We studied the brains of 1672 older decedents with baseline FRS and measured CVD pathologies including macroinfarcts, microinfarcts, atherosclerosis, arteriolosclerosis, and cerebral amyloid angiopathy. We employed a series of logistic regressions to examine the association of baseline FRS with each of the 5 CVD pathologies. Results: Average age at baseline was 80.5±7.0 years and average age at death was 89.2±6.7 years. A higher baseline FRS was associated with higher odds of macroinfarcts (odds ratio, 1.10 [95% CI, 1.07–1.13], P <0.001), microinfarcts (odds ratio, 1.04 [95% CI, 1.01–1.07], P =0.009), atherosclerosis (odds ratio, 1.07 [95% CI, 1.04–1.11], P <0.001), and arteriolosclerosis (odds ratio, 1.04 [95% CI, 1.01–1.07], P =0.005). C statistics for these models ranged from 0.537 to 0.595 indicating low accuracy for predicting CVD pathologies. FRS was not associated with the presence of cerebral amyloid angiopathy. Conclusions: A higher FRS score in older adults is associated with higher odds of some, but not all, CVD pathologies, with low discrimination at the individual level. Further work is needed to develop a more robust risk score to identify adults at risk for accumulating CVD pathologies.
