Antisocial behavior with callous-unemotional traits is associated with widespread disruptions to white matter structural connectivity among low-income, urban males

NeuroImage: Clinical, 2019
Antisocial behavior (AB), including violence, criminality, and substance abuse, is often linked to deficits in emotion processing, reward-related learning, and inhibitory control, as well as their associated neural networks.

Widespread Effects of Alcohol on White Matter Microstructure [PDF]

Alcoholism: Clinical and Experimental Research, 2014
BackgroundEvidence suggests that chronic misuse of alcohol may preferentially affect the integrity of frontal white matter (WM) tracts, which can impact executive functions important to achieve and maintain abstinence.MethodsGlobal and regional WM microstructure was assessed using diffusion magnetic resonance measures of fractional anisotropy (FA) for ...

White matter changes underlie hypertension-related cognitive decline in older adults

NeuroImage: Clinical, 2023
Hypertension has been well recognized as a risk factor for cognitive impairment and dementia. Although the underlying mechanisms of hypertension-affected cognitive deterioration are not fully understood, white matter changes (WMCs) seem to play an ...

Response inhibition is associated with white matter microstructure in children [PDF]

Neuropsychologia, 2010
Cognitive control of thoughts, actions and emotions is important for normal behaviour and the development of such control continues throughout childhood and adolescence. Several lines of evidence suggest that response inhibition is primarily mediated by a right-lateralized network involving inferior frontal gyrus (IFG), presupplementary motor cortex ...

Microstructural White Matter Properties Mediate the Association between APOE and Perceptual Speed in Very Old Persons without Dementia. [PDF]

PLoS ONE, 2015
Reduced white matter integrity, as indicated by lower fractional anisotropy (FA) and higher mean diffusivity (MD), has been related to poorer perceptual speed (PS) performance. As the ε4 allele has been associated with lower white matter integrity in old

Effect of sex on the APOE4-aging interaction in the white matter microstructure of cognitively normal older adults using diffusion-tensor MRI with orthogonal-tensor decomposition (DT-DOME)

Frontiers in Neuroscience, 2023
The influence of the apolipoprotein E ε4 allele (APOE4) on brain microstructure of cognitively normal older adults remains incompletely understood, in part due to heterogeneity within study populations.

Histological validation of high-resolution DTI in human post mortem tissue

Frontiers in Neuroanatomy, 2015
Diffusion tensor imaging (DTI) is amongst the simplest mathematical models available for diffusion magnetic resonance imaging, yet still by far the most used one.

White matter damage and cognitive impairment after traumatic brain injury

, 2010
White matter disruption is an important determinant of cognitive impairment after brain injury, but conventional neuroimaging underestimates its extent.
