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 ...

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.

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.

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.

Aberrant white matter microstructure in treatment-resistant schizophrenia✰ [PDF]

Psychiatry Research: Neuroimaging, 2020
Treatment response in schizophrenia divides into three subcategories: treatment-responsive (first-line responders; FLR), treatment-resistant (TRS), and ultra-treatment-resistant schizophrenia (UTRS). White matter abnormalities could drive antipsychotic resistance but little work has investigated differences between TRS and UTRS. The current study aimed

Premature white matter microstructure in female children with a history of concussion

Developmental Cognitive Neuroscience, 2023
Childhood concussion may interfere with neurodevelopment and influence cognition. Females are more likely to experience persistent symptoms after concussion, yet the sex-specific impact of concussion on brain microstructure in children is understudied ...

White matter microstructure alterations: a study of alcoholics with and without post-traumatic stress disorder. [PDF]

PLoS ONE, 2013
Many brain imaging studies have demonstrated reductions in gray and white matter volumes in alcoholism, with fewer investigators using diffusion tensor imaging (DTI) to examine the integrity of white matter pathways.

Microstructural white matter changes preceding white matter hyperintensities in migraine

Neurology, 2019
We used magnetization transfer imaging to assess white matter tissue integrity in migraine, to explore whether white matter microstructure was more diffusely affected beyond visible white matter hyperintensities (WMHs), and to explore whether focal invisible microstructural changes precede visible focal WMHs in migraineurs.We included 137 migraineurs ...

General factors of white matter microstructure from DTI and NODDI in the developing brain

NeuroImage, 2022
Preterm birth is closely associated with diffuse white matter dysmaturation inferred from diffusion MRI and neurocognitive impairment in childhood. Diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI) are distinct

White matter hyperintensity microstructure in amyloid dysmetabolism [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2016
Accumulating evidence suggests associations between cerebrovascular disease (CVD) and Alzheimer’s disease (AD). White matter hyperintensities of presumed vascular origin (WMHs) are increased in subjects with mild cognitive impairment (MCI) and AD, but the exact pathomechanistic link is unknown.
