White matter volumes and periventricular white matter hyperintensities in aging and dementia

Neurology, 2000
To determine the relationship between MRI periventricular white matter hyperintensities, cerebral white matter volumes, neuropathologic findings, and cognitive status in aged individuals.The significance of periventricular white matter hyperintensities seen on MR images in aged individuals remains controversial.

White matter lesion volumes and caudate volumes in late‐life depression

International Journal of Geriatric Psychiatry, 2006
AbstractBackgroundDecreased caudate volumes and increased white matter lesions (WMLs) are associated both with aging and late‐life depression, but the relationship between the two is unclear. We examined the association between WML and caudate volume, hypothesizing there would be a negative association, which would be stronger for WMLs located in ...

Abnormal gray matter and white matter volume in ‘Internet gaming addicts’

Addictive Behaviors, 2015
Internet gaming addiction (IGA) is usually defined as the inability of an individual to control his/her use of the Internet with serious negative consequences. It is becoming a prevalent mental health concern around the world. To understand whether Internet gaming addiction contributes to cerebral structural changes, the present study examined the ...

White matter volumes in youth offspring of bipolar parents

Journal of Affective Disorders, 2017
Studying youth at high risk of developing bipolar disorder may clarify neurobiological factors associated with vulnerability to this illness. We present here a baseline characterization of brain structure in youth at-risk for bipolar disorder.Magnetic resonance images were obtained from 115 child and adolescent offspring of bipolar disorder type I ...

White matter volume predicts reaction time instability

Neuropsychologia, 2007
Information processing speed is a central concept in cognitive psychology and neuropsychology. Previous studies have mostly focused on mean reaction time (RT), and largely ignored intra-individual differences (the standard deviation of the RT: sdRT). Still, intra-individual inconsistency across trials has been shown to correlate with age, neurological ...

Abnormal gray and white matter volume in delusional infestation

Progress in Neuro-Psychopharmacology and Biological Psychiatry, 2013
Little is known about the neural basis of delusional infestation (DI), the delusional belief to be infested with pathogens. Case series and the response to anti-dopaminergic medication indicate disruptions in dopaminergic neurotransmission in the striatum (caudate, putamen), but did not allow for population-based inference.

White matter lesions volume and motor performances in the elderly

Annals of Neurology, 2009
Abstract Objectives To investigate the cross‐sectional and longitudinal associations between performance‐based measures of motor function and volume of white matter lesions (WMLs), and to examine the influence of the localization of these lesions.

Reduced hippocampal volume and total white matter volume in posttraumatic stress disorder

Biological Psychiatry, 2002
Reduced hippocampal volumes in posttraumatic stress disorder (PTSD) patients are thought to reflect specific changes of this structure. Previous magnetic resonance imaging (MRI) studies have not consistently examined indices of overall brain atrophy, therefore it cannot be completely ruled out that hippocampal changes are explained by whole-brain ...
