Gray Matter Age Prediction as a Biomarker for Risk of Dementia

Aging and dementia: more gray hair and less gray matter.

Medical Risk factors for dementia; A case-control study

Introduction: Dementia, the fifth cause of death in older adults with the most significant financial, social and caring burden on health systems across the world. Aim: to determine the most common medical risk factors for dementia in the retired population. Methods: A case-control methodology was utilized for this study, within which 180 established dementia patients compared to 371 controls ...

Quantitative meta-analysis of gray matter abnormalities in semantic dementia.

Cumulative evidence of gray matter abnormalities in semantic dementia (SD) has been reported using voxel-based morphometry (VBM). However, these studies have not been reviewed quantitatively. To estimate gray matter changes in SD quantitatively, we systematically searched whole-brain VBM studies comparing SD patients with healthy controls in the PubMed, ISI Web of Science, and EMABSE databases ...

A Novel MRI Biomarker of Spinal Cord White Matter Injury: T2*-Weighted White Matter to Gray Matter Signal Intensity Ratio.

BACKGROUND AND PURPOSE T2*-weighted imaging provides sharp contrast between spinal cord GM and WM, allowing their segmentation and cross-sectional area measurement. Injured WM demonstrates T2*WI hyperintensity but requires normalization for quantitative use. We introduce T2*WI WM/GM signal-intensity ratio and compare it against cross-sectional area, the DTI metric fractional anisotropy, and mag...
