White matter microstructure correlates of age, sex, handedness and motor ability in a population-based sample of 3031 school-age children

NeuroImage, 2021
Understanding the development of white matter microstructure in the general population is an imperative precursor to identifying its involvement in psychopathology. Previous studies have reported changes in white matter microstructure associated with age

Widespread White Matter Microstructure Alterations Based on Diffusion Tensor Imaging and Diffusion Kurtosis Imaging in Patients With Pontine Infarction

Frontiers in Aging Neuroscience, 2021
Neurological deficits after stroke are closely related to white matter microstructure damage. However, secondary changes in white matter microstructure after pontine infarction (PI) in the whole brain remain unclear.

Modeling white matter microstructure [PDF]

Functional Neurology, 2016
Quantitative magnetic resonance imaging can be combined with advanced biophysical models to measure microstructural features of white matter. Non-invasive microstructural imaging has the potential to revolutionize neuroscience, and acquiring these measures in clinically feasible times would greatly improve patient monitoring and clinical studies of ...

Schizophrenia polygenic risk score influence on white matter microstructure [PDF]

, 2020
Schizophrenia (SZ) and bipolar disorder (BD) are highly heritable, share symptomatology, and have a polygenic architecture. The impact of recent polygenic risk scores (PRS) for psychosis, which combine multiple genome-wide associated risk variations ...

Cigarette smoking and white matter microstructure [PDF]

Psychopharmacology, 2012
Diffusion tensor imaging has been used before in testing associations between cigarette smoking and white matter integrity, with inconsistent results. Published reports indicate higher fractional anisotropy (FA, a measure of linear water diffusion) in some brain regions and lower FA in others in adult smokers compared to nonsmokers.

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 ...

Neuropsychiatry and White Matter Microstructure in Huntington’s Disease [PDF]

Journal of Huntington's Disease, 2015
Abstract Background: Neuropsychiatric symptoms in Huntington’s disease (HD) are often evident prior to clinical diagnosis. Apathy is highly correlated with disease progression, while depression and irritability occur at different stages of the disease, both before and after clinical onset.

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 ...
