Patients with bipolar disorder (BD) show alterations in both gray matter volume (GMV) and white matter (WM) integrity compared with healthy controls (HC). However, it remains unclear whether the phenotypically distinct BD subtypes (BD-I and BD-II) also exhibit brain structural differences. This...

MRI features of grey matter atrophy and White Matter Hyperintensities (WMHs) of cerebrovascular origin have been linked to cognitive symptoms in Parkinson's disease (PD) (Yau 2018, Dadar 2018). Here we assess the relationship between WMH burden, gray matter atrophy in the Hippocampi and cognitive...
Voxel-based morphometry versus region of interest: a comparison of two methods for analyzing gray matter differences in schizophrenia Many previous studies exploring cortical gray matter (GM) differences in schizophrenia have used "region of interest" (ROI) measurements to manually deline... NR ...
By 24 h post-HI, damage was apparent in both white and gray matter. Thus, MR imaging detected acute tissue edema following cerebral HI in both gray and white matter but did not distinguish between the early irreversible tissue injury detected histologically in white but not gray matter in ...
Width of the third ventricle, width of the central sulcus, and attenuation in gray matter (GM) and white matter (WM) from the same area of the basal ganglia, centrum semiovale, and high convexity were statistically compared between AMCT and PMCT. Both the width of the third ventricle and...
It has been shown that scores in both subtests show the best preservation with aging versus other subtests of the WAIS (Ardila, 2007). We analyzed the correlation between global gray/white matter volumes and these cognitive functions. In evaluating global gray matter volume, we calculated the ...
In keeping with the grey matter findings, white matter tracts within the temporal lobes are consistently affected with significant changes identified in the inferior longitudinal fasciculus (ILF) and uncinate fasciculus (UNC) [19]. Involvement of white matter tracts connecting temporal lobes to other ...
groups of patients with focal brain lesions in different parts of their brains. More specifically, they wanted to know if such lesions were more likely to result in cognitive impairment if they occurred in white matter versus gray matter—tissue in the brain made up mainly ofnerve cellsand ...
