Objective: The clinical and pathological characteristics of 10 cases of cerebral amyloid angiopathy (CAA)-related cerebral lobar hemorrhage (CLH) that was diagnosed at autopsy were investigated to facilitate the diagnosis of this condition.
Methods: The clinical characteristics of 10 cases of CAA-related CLH were retrospectively reviewed, and a neuropathological examination was performed on autopsy samples.
Results: The 10 cases included two with a single lobar hemorrhage and eight with multifocal lobar hemorrhages. In all of the cases, the hemorrhage bled into the subarachnoid space. Pathological examinations of the 10 cases revealed microaneurysms in two, double barrel-like changes in four, multifocal arteriolar clusters in five, obliterative onion skin-like intimal changes in four, fibrinoid necrosis of the vessels in seven, neurofibrillary tangles in eight, and senile plaques in five cases.
Conclusion: CAA-related CLHs were located primarily in the parietal, temporal, and occipital lobes. These hemorrhages normally consisted of multiple repeated CLHs that frequently bled into the subarachnoid space. CAA-associated microvascular lesions may be the pathological factor underlying CLH.

Introduction: While cerebral amyloid angiopathy is likely responsible for intracerebral hemorrhage (ICH) occurring in superficial (grey matter, vermis) cerebellar locations, it is unclear whether hypertensive arteriopathy (HA), the other major cerebral small vessel disease (cSVD), is associated with cerebellar ICH (cICH) in deep (white matter, deep nuclei, cerebellar peduncle) regions. We tested the hypothesis that HA-associated neuroimaging markers are significantly associated with deep cICH compared to superficial cICH.
Patients And Methods: Brain MRI scans from consecutive non-traumatic cICH patients admitted to a referral center were analyzed for cSVD markers.

Background And Purpose: Lobar intracerebral hemorrhage (ICH) is associated with a high risk of recurrence, particularly in elderly patients, where cerebral amyloid angiopathy (CAA) is often the primary cause. Diagnostic markers of CAA-related ICH, including subarachnoid hemorrhage (SAH) and finger-like projection (FLP), have recently been developed. Here, we aimed to explore the associations between SAH, FLP and the risk of ICH recurrence in lobar ICH patients.

Seizure is a relatively common neurological consequence after spontaneous intracerebral hemorrhage (SICH). This study aimed to investigate risk factors of early, late, and overall seizures in patients with SICH. Retrospective analysis was performed on all patients with SICH who completed two years of follow-up.

Importance: Baseline cerebral microbleeds (CMBs) and APOE ε4 allele copy number are important risk factors for amyloid-related imaging abnormalities in patients with Alzheimer disease (AD) receiving therapies to lower amyloid-β plaque levels.
Objective: To provide prevalence estimates of any, no more than 4, or fewer than 2 CMBs in association with amyloid status, APOE ε4 copy number, and age.
Design, Setting, And Participants: This cross-sectional study used data included in the Amyloid Biomarker Study data pooling initiative (January 1, 2012, to the present [data collection is ongoing]).

Objectives: Cerebral amyloid angiopathy (CAA) is the main driver of amyloid-related imaging abnormalities (ARIAs) in Alzheimer disease (AD). We compared different versions of the Boston criteria for CAA diagnosis in AD.
Methods: This article presents a single-center analysis (outpatient neurodegenerative clinic) of patients with AD with mild cognitive impairment (MCI) or early dementia, meeting NIA-AA criteria and having biological amyloid confirmation (CSF or imaging).
