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.

Prefrontal gray matter volume mediates genetic risks for obesity

Molecular Psychiatry, 2017
Genetic and neuroimaging research has identified neurobiological correlates of obesity. However, evidence for an integrated model of genetic risk and brain structural alterations in the pathophysiology of obesity is still absent. Here we investigated the relationship between polygenic risk for obesity, gray matter structure and body mass index (BMI) by

Localized gray matter volume abnormalities in generalized anxiety disorder

European Archives of Psychiatry and Clinical Neuroscience, 2010
Generalized anxiety disorder (GAD) is characterized by excessive and persistent worrying. Neural substrates of this disorder are insufficiently understood, which relates to functional as well as to structural brain abnormalities. Especially, findings on the neuroanatomy of GAD have been inconsistent and were predominantly derived from pediatric samples.

Amygdalar Gray Matter Volume and Social Relating in Schizophrenia

Neuropsychobiology, 2016
<b><i>Background:</i></b> Poor social relating is a prominent feature of schizophrenia. The amygdala has been suggested as an important node in social brain networks. <b><i>Methods:</i></b> By using structural magnetic resonance imaging, this study examined, for the first time, the relationship between ...

Prefrontal Gray Matter Volume Reduction in First Episode Schizophrenia

Cerebral Cortex, 2001
Functional measures have consistently shown prefrontal abnormalities in schizophrenia. However, structural magnetic resonance imaging (MRI) findings of prefrontal volume reduction have been less consistent. In this study, we evaluated prefrontal gray matter volume in first episode (first hospitalized) patients diagnosed with schizophrenia, compared ...

Smaller Frontal Gray Matter Volume in Postmortem Schizophrenic Brains

American Journal of Psychiatry, 2002
The prefrontal cortex exhibits prominent functional, biochemical, and anatomic abnormalities in schizophrenic patients. However, smaller than normal volume of the frontal lobe has not been found in previous postmortem studies of schizophrenic subjects, and magnetic resonance imaging (MRI) scans of schizophrenic subjects have not consistently revealed ...

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.

Gray matter volume modifications in migraine

Neurology, 2018
To explore cross-sectional and longitudinal gray matter (GM) volume changes in patients with migraine and their association with patients' clinical characteristics and disease activity.Brain T2-weighted and 3-dimensional T1-weighted scans were acquired from 73 episodic migraineurs and 46 age- and sex-matched nonmigraine controls at baseline.

Normal frontal lobe gray matter-white matter CT volume ratio in children

Neuroradiology, 1985
We attempted to establish a computed tomographic value representing the normal volume ratio of gray matter to white matter (G/W) in children in order to have a baseline for studying various developmental disorders such as white matter hypoplasia. The records of 150 children 16 years of age or younger who had normal cranial computed tomography were ...
