Early detection of microstructural white matter changes associated with arterial pulsatility

Increased cerebral blood flow pulsatility is common in vascular dementia and is associated with macrostructural damage to cerebral white matter or leukoaraiosis (LA). In this study, we examine whether cerebral blood flow pulsatility is associated with macrostructural and microstructural changes in cerebral white matter in older adults with no or mild LA and no evidence of dementia. Diffusion Te...

PS249. White matter microstructural changes are associated with alcohol use in patients with panic disorder

BACKGROUND A close relationship between panic disorder (PD) and alcohol use disorder (AUD) has been suggested. We aimed to investigate alterations in white matter (WM) volume or integrity in patients with PD comorbid with AUD. METHODS Forty-nine patients with PD, free of comorbid AUD (PD-AUD), and 20 patients with PD comorbid with AUD (PD+AUD) were investigated. All subjects were assessed usi...

Early microstructural white matter changes in patients with HIV: A diffusion tensor imaging study

BACKGROUND Previous studies have reported white matter (WM) brain alterations in asymptomatic patients with human immunodeficiency virus (HIV). METHODS We compared diffusion tensor imaging (DTI) derived WM fractional anisotropy (FA) between HIV-patients with and without mild macroscopic brain lesions determined using standard magnetic resonance imaging (MRI). We furthermore investigated wheth...

Multifractal analysis of deep white matter microstructural changes on MRI in relation to early-stage atherosclerosis.

Multifractal analysis based on generalized concepts of fractals has been applied to evaluate biological tissues composed of complex structures. This type of analysis can provide a precise quantitative description of a broad range of heterogeneous phenomena. Previously, we applied multifractal analysis to describe heterogeneity in white matter signal fluctuation on T2-weighted MR images as a new...

Longitudinal changes in microstructural white matter metrics in Alzheimer's disease

BACKGROUND Alzheimer's disease (AD) is a progressive neurodegenerative disorder. Current avenues of AD research focus on pre-symptomatic biomarkers that will assist with early diagnosis of AD. The majority of magnetic resonance imaging (MRI) based biomarker research to date has focused on neuronal loss in grey matter and there is a paucity of research on white matter. METHODS Longitudinal DTI...
