Objective: Cerebral microbleeds (CMBs) are known as the neuroimaging markers of risk in stroke and dementia. Many studies on CMBs in elderly patients with hemorrhagic or ischemic stroke have been reported; however, reports on CMBs in young populations with intracerebral hemorrhage (ICH) are lacking.
Materials And Methods: A total of 272 patients aged 18-54 years presented to our hospital with ICH between December 2009 and August 2017. Among these, CMB presence, count, and topography with respect to ICH were evaluated on magnetic resonance imaging (MRI) gradient echo images (GREs). We also evaluated the prevalence and risk factors of CMBs.
Results: Among 272 patients, only 66 underwent GRE T2-weighted MRI. CMBs were detected in 40 patients (61%), with 29 (73%) being of the multifocal type. Among the 219 CMBs, 150 (68.5%) were of the deep type and 69 (31.5%) of the lobar type. CMB prevalence was higher in men. In multivariate logistic regression analysis, history of hypertension (adjusted odds ratio [aOR], 4.048; 95% confidence interval [CI], 1.14-14.32; = 0.030), and male sex (aOR, 4.233; 95% CI, 1.09-16.48; = 0.037) were independently associated with CMBs.
Conclusion: In young patients who presented with spontaneous ICH, CMBs were highly prevalent in 61% of patients and strongly associated with history of hypertension and male sex.

Objectives: This study investigated the correlation between retinal vasculature and cerebral small vessel disease (CSVD) imaging markers, providing new evidence for the retina-brain association.
Methods: Two hundred and thirty-nine participants aged 55-85 were enrolled in the study. CSVD indicators, encompassing white matter hyperintensities (WMHs), lacunes (LAs), cerebral microbleeds (CMBs), and enlarged perivascular spaces (EPVSs), were assessed.

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]).

Purpose Of Review: Recent advancements in molecular biomarkers and therapeutic options for Alzheimer's disease have brought into focus the need for greater progress in the second most common cause of dementia, vascular cognitive impairment and dementia (VCID). We examine how the study of monogenic causes of VCID has contributed to the understanding of its pathophysiology and potential biomarker and treatment research.
Recent Findings: It is widely accepted that conditions which disrupt the cerebral small vessels contribute to vascular pathologies including stroke and cerebral microbleeds, ultimately leading to vascular cognitive impairment and dementia.

Background: Neonatal cerebral microbleeds (CMBs) occur infrequently, and during the initial phase, they often present without noticeable clinical symptoms, which can result in delays in both diagnosis and treatment. There has been relatively little research conducted on neonatal CMBs, with even less focus on their related risk factors. However, identifying risk factors and proactively preventing microbleeds is particularly crucial for effective treatment.

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).
