Correlation between baseline regional gray matter volume and global gray matter volume decline rate

NeuroImage, 2011
Evaluating whole-brain or global gray matter volume decline rate is important in distinguishing neurodegenerative diseases from normal aging and in anticipating cognitive decline over a given period in non-demented subjects. Whether a significant negative correlation exists between baseline regional gray matter volume of several regions and global gray

Neck Circumference and Cerebral Gray Matter Volume

Alzheimer Disease & Associated Disorders, 2020
Background: While obesity is linked with brain atrophy and dementia incidence, associations with regional adiposity are uncertain. Our goal was to determine whether cerebral gray matter volume is related to neck circumference (NC), a measure of regional adiposity having unique relationships with metabolic disorders and ...

Sleep Duration, Sleep Apnea, and Gray Matter Volume

Journal of Geriatric Psychiatry and Neurology, 2021
This study aimed to evaluate the effect of sleep duration on brain structures in the presence versus absence of sleep apnea in middle-aged and older individuals. The study investigated a population-based sample of 2,560 individuals, aged 49-80 years. The presence of sleep apnea and self-reported sleep duration were examined in relation to gray matter ...

Gray matter volume differences and the effects of smoking on gray matter in schizophrenia

Schizophrenia Research, 2007
Many studies have evaluated differences in gray matter volume in schizophrenia, but have not considered the possible effects of smoking, which is extraordinarily common in people with the illness. The present study used voxel-based morphometry (VBM) to examine differences in gray matter in subjects with schizophrenia and evaluate the effects of smoking

Volume Changes in Gray Matter in Patients With Schizophrenia

American Journal of Psychiatry, 2002
Schizophrenia is generally characterized by a progressive decline in functioning. Although structural brain abnormalities, particularly decrements in gray matter volume, are considered important to the pathology of schizophrenia, it is not resolved whether the brain abnormalities become more prominent over time.Magnetic resonance brain images from 159 ...

Gray matter volume in relation to cardio-vascular stiffness

Journal of the Neurological Sciences, 2014
Hemodynamic disturbances are associated with aging as well as the chronic process of left ventricular and arterial stiffening. This process can influence gray matter volume and thereby contribute to brain atrophy. We performed a comprehensive assessment of left ventricular and arterial function as well as central hemodynamics.

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.

Decreased regional cortical gray matter volume in schizophrenia

American Journal of Psychiatry, 1994
The authors hypothesized that cortical gray matter volume reduction in schizophrenia is greatest in the heteromodal association cortex. This area comprises a highly integrated, reciprocally interconnected system that coordinates higher order cortical functions.Total brain and regional gray matter volumes were calculated in 46 schizophrenic patients and

Changes in Gray Matter Volume in Patients with Bipolar Disorder

Biological Psychiatry, 2005
Several lines of evidence suggest the presence of neurofunctional abnormalities in patients with bipolar disorder. These functional abnormalities may stem from structural pathology in these or connected brain regions. Previous studies have generally used a region of interest (ROI) approach to study morphologic changes in bipolar disorder with ...

Reduced volume of gray matter in patients with trigeminal neuralgia

Brain Imaging and Behavior, 2016
Accumulating evidence from brain structural imaging studies has supported that chronic pain could induce changes in brain gray matter volume. However, few studies have focused on the gray matter alterations of Trigeminal neuralgia (TN). In this study, twenty-eight TN patients (thirteen females; mean age, 45.86 years ±11.17) and 28 healthy controls (HC;
