Both brain atrophy and T2-weighted white matter hyperintensities (WMH) are common findings in the brains of asymptomatic elderly individuals as well as in disease-specific brains. The study of the relationship between these two salient features is therefore important. To investigate such a relationship, we performed a brain magnetic resonance imaging (MRI) study on 397 asymptomatic individuals ...

AIMS Alcohol induces cytokine secretion by Kupffer cells, which may exert also deleterious effects on distant organs, mediated in part by cytokine-derived increased production of reactive oxygen species (ROS). It is therefore important to assess antioxidant levels. The objective of this study is to analyse the relation of antioxidant vitamins with brain atrophy and cognitive dysfunction. METH...

Using magnetic resonance imaging and digitized brain computed tomography, we evaluated 33 elderly patients with documented lacunar stroke and divided them into three groups (nondemented, n = 15; borderline, n = 9; and demented, n = 9) by neuropsychological assessments and DSM III criteria. We evaluated the extent of white matter lesions and the degree of atrophy of specific anatomic structures,...

We examined the association between brain atrophy and vascular brain lesions (i.e., white matter lesions [WMLs] or brain infarcts), alone or in combination, with decline in memory and executive functioning over 4 years of follow-up in 448 patients (57 ± 9.5 years) with symptomatic atherosclerotic disease from the Second Manifestations of ARTerial disease--Magnetic Resonance SMART-MR study. Auto...

OBJECTIVE To determine whether baseline cerebral atrophy can predict the rate of future chronic subdural hematoma (CSDH) after head trauma and compare indirect markers of brain atrophy with volumetric analysis of computed tomography (CT). METHODS Single institution case-control study involving 1,476 patients who visited our hospital after head trauma from January 2009 to December 2014. Forty-...

We aimed to identify and characterize subtypes of Alzheimer's disease (AD) exhibiting different patterns of regional brain atrophy on MRI using age- and gender-specific norms of regional brain volumes. AD subjects included in the Alzheimer's Disease Neuroimaging Initiative study were classified into subtypes based on standardized values (Z-scores) of hippocampal and regional cortical volumes on...

We describe an improved method of measuring brain atrophy rates from serial MRI for multi-site imaging studies of Alzheimer's disease (AD). The method (referred to as KN-BSI) improves an existing brain atrophy measurement technique-the boundary shift integral (classic-BSI), by performing tissue-specific intensity normalization and parameter selection. We applied KN-BSI to measure brain atrophy ...

Hemoglobin degradation products result in brain injury after intracerebral hemorrhage (ICH). Recent studies found that intracerebral infusion of heme oxygenase inhibitors reduces hemoglobin- and ICH-induced brain edema in rats and pigs. The present study examined whether systemic use of zinc protoporphyrin (ZnPP), a heme oxygenase inhibitor, can attenuate brain edema, behavioral deficits, and b...
