Normal brain aging is characterized by declining neuronal integrity, yet it remains unclear how microstructural injury influences cognitive aging and whether such mechanisms differ between sexes. Using restriction spectrum imaging (RSI), we examined sex differences in associations between brain microstructure and cognitive function in 147 community-dwelling older men and women (56-99 years). Gray and white matter microstructure correlated with global cognition, executive function, visuospatial m...

Introduction: Cardiac papillary fibroelastomas (PFEs) are the most common primary benign cardiac tumors, although they are somewhat unusual in children and typically seen on the left-sided cardiac valves. Case summary: A 10-week-old patient was found to have a partial atrioventricular canal defect, with associated tricuspid and mitral regurgitation. He was medically managed until 1 year of age, when surgical correction was done. During the procedure, a PFE was found incidentally on the TV. Concl...

Electroencephalography (EEG) and magnetoencephalography (MEG) are among the most important techniques for non-invasively studying cognition and disease in the human brain. These signals are known to originate from cortical neural activity, typically described in terms of current dipoles. While the link between cortical current dipoles and EEG/MEG signals is relatively well understood, surprisingly little is known about the link between different kinds of neural activity and the current dipoles t...

Abstract: Congenital fistulae covers a wide spectrum of vascular disorder including arteriovenous malformations and venovenous communications. This chapter primarily deals with the diagnosis and management of coronary arterial malformations and specifically fistulae. However the catheter intervention techniques described can also be applied to extra-cardiac malformations as well. We detail both antegrade and retrograde approaches to interventions techniques. We discussed the use of various coils...

ABSTRACT Importance Both cognitive reserve and modifiable lifestyle behaviors are associated with dementia risk. The effect of early lifestyle behaviors and cognitive reserve on late midlife brain aging could inform early identification and risk reduction of future dementia. Objective Determine associations of young adult cognitive reserve, early midlife lifestyle behaviors, and the reserve-by-lifestyle interaction on late midlife brain age. Examine the relationship between mild cognitive impair...

Abstract Cytoarchitectural brain changes within gray matter and fiber tracts during normal aging remain poorly characterized, and it is unclear whether rates and patterns of brain aging differ by sex. This study used restriction spectrum imaging (RSI) to examine associations between age and brain microstructure in 147 community-dwelling participants (aged 56-99). Widespread associations with older age in multiple diffusion compartments, including increased free water, decreased restricted and hi...

Brain morphology has been shown to be highly heritable, yet only a small portion of the heritability is explained by the genetic variants discovered so far. Here we exploit the distributed nature of genetic effects across the brain and apply the Multivariate Omnibus Statistical Test (MOSTest) to genome-wide association studies (GWAS) of vertex-wise structural magnetic resonance imaging (MRI) measures from N=35,657 participants in the UK Biobank. We identified 1598 loci for cortical surface area ...
