Change in brain volume and cortical thickness after behavioral and surgical weight loss intervention

NeuroImage: Clinical, 2019
Obesity is associated with reduced cortical thickness and brain volume, which may be related to poor nutrition. Given that brain atrophy in anorexia nervosa recovers with nutritional improvements and weight gain, it is worth examining how brain structure

White matter is increased in the brains of adults with neurofibromatosis 1

Orphanet Journal of Rare Diseases, 2022
Background Neurofibromatosis 1 (NF1) is a rare autosomal dominant disease characterized by increased Schwann cell proliferation in peripheral nerves. Several small studies of brain morphology in children with NF1 have found increased total brain volume ...

Brain Structural Alterations, Diabetes Biomarkers, and Cognitive Performance in Older Adults With Dysglycemia

Frontiers in Neurology, 2021
Despite the high risk of dementia in older adults with type 2 diabetes, the neuroanatomical correlates of cognitive dysfunction that are particularly affected by diabetes are not well characterized.

Partial‐volume model for determining white matter and gray matter cerebral blood volume for analysis of gliomas [PDF]

Journal of Magnetic Resonance Imaging, 2006
AbstractPurposeTo model the partial voluming of gray matter (GM) and white matter (WM) in perfusion imaging, and to use this model to estimate the cerebral blood volume (CBV) of pure WM and GM, which could then be used to normalize data across patients in preparation for analyzing tumor perfusion.Materials and MethodsDynamic susceptibility contrast ...

Regional grey and white matter changes in heavy male smokers.

PLoS ONE, 2011
Cigarette smoking is highly prevalent in the general population but the effects of chronic smoking on brain structures are still unclear. Previous studies have found mixed results regarding regional grey matter abnormalities in smokers.

Impact of Decreased Visibility of Deep Medullary Veins on White Matter Integrity in Patients with Cerebral Small Vessel Disease

Journal of Integrative Neuroscience, 2023
Background: Based on susceptibility-weighted imaging (SWI) visibility, deep medullary vein (DMV) scores are related to white matter damage (WMD) in patients with cerebral small vessel disease (CSVD).

Percentage brain volume change in multiple sclerosis mainly reflects white matter and cortical volume [PDF]

, 2022
Brain atrophy in multiple sclerosis (MS), as measured by percentage brain volume change (PBVC) from brain magnetic resonance imaging (MRI), has been established as an outcome parameter in clinical trials.

Automated White Matter Total Lesion Volume Segmentation in Diabetes [PDF]

American Journal of Neuroradiology, 2013
WM lesion segmentation is often performed with the use of subjective rating scales because manual methods are laborious and tedious; however, automated methods are now available. We compared the performance of total lesion volume grading computed by use of an automated WM lesion segmentation algorithm with that of subjective rating scales and expert ...

Influence of white matter inhomogeneous anisotropy on EEG forward computing [PDF]

, 2008
In this paper, we model the human head using the Volume and Wang’s constraint methods, and study the inhomogeneous anisotropic conductivity for white matter (WM) using finite element method (FEM).
