MRI study of white matter microstructural alterations in attention deficit/hyperactivity disorder

Sichuan jingshen weisheng, 2021
The development of cerebral white matter is essential for the establishment of normal behavior and cognitive functions， and several studies have shown that the alterations in white matter microstructure are associated with core symptoms and cognitive ...

Crystallinity characterization of white matter in the human brain

New Journal of Physics, 2021
Human brain tissue is a heterogeneous material, consisting of soft outer grey matter tethered internally by stiffer cords of white matter. These white matter tracts conduct electrical impulses between grey matter regions, thereby underpinning neuronal ...

Associations of physical activity and screen time with white matter microstructure in children from the general population

NeuroImage, 2020
Physical activity and sedentary behaviors have been linked to a variety of general health benefits and problems. However, few studies have examined how physical activity during childhood is related to brain development, with the majority of work to date ...

Cigarette smoking and white matter microstructure in schizophrenia [PDF]

Psychiatry Research: Neuroimaging, 2012
The majority of patients with schizophrenia smoke cigarettes. Both nicotine use and schizophrenia have been associated with alterations in brain white matter microstructure as measured by diffusion tensor imaging (DTI). The purpose of this study was to examine fractional anisotropy (FA) in smoking and non-smoking patients with schizophrenia and in ...

Abdominal obesity and white matter microstructure in midlife [PDF]

Human Brain Mapping, 2017
AbstractThe aging U.S. population and the recent rise in the prevalence of obesity are two phenomena of great importance to public health. In addition, research suggests that midlife body mass index (BMI) is a risk factor for dementia, a particularly costly disease, in later life.

The development of brain white matter microstructure

NeuroImage, 2018
Throughout infancy, childhood, and adolescence, our brains undergo remarkable changes. Processes including myelination and synaptogenesis occur rapidly across the first 2-3 years of life, and ongoing brain remodeling continues into young adulthood.

Multiparametric mapping of white matter microstructure in catatonia [PDF]

Neuropsychopharmacology, 2020
Catatonia is characterized by motor, affective and behavioral abnormalities. To date, the specific role of white matter (WM) abnormalities in schizophrenia spectrum disorders (SSD) patients with catatonia is largely unknown. In this study, diffusion magnetic resonance imaging (dMRI) data were collected from 111 right-handed SSD patients and 28 healthy ...

In vivo myelin imaging and tissue microstructure in white matter hyperintensities and perilesional white matter [PDF]

Brain Communications, 2021
Abstract White matter hyperintensities negatively impact white matter structure and relate to cognitive decline in aging. Diffusion tensor imaging detects changes to white matter microstructure, both within the white matter hyperintensity and extending into surrounding (perilesional) normal-appearing white matter.

White Matter Regions With Low Microstructure in Young Adults Spatially Coincide With White Matter Hyperintensities in Older Adults

Frontiers in Aging Neuroscience, 2019
Microstructural and macrostructural white matter damage occurs frequently with aging, is associated with negative health outcomes, and can be imaged non-invasively as fractional anisotropy (FA) and white matter hyperintensities (WMH), respectively.
