Widespread Cerebral Gray Matter Volume Deficits in Schizophrenia

Archives of General Psychiatry, 1992
Magnetic resonance imaging was used to investigate whether the structural brain differences commonly observed in patients with schizophrenia as compared with normal control subjects are specific to gray or white matter, and furthermore whether such abnormalities are localizable to circumscribed cortical regions. Accordingly, 22 patients meeting DSM-III-

Hypothalamic gray matter volume loss in hypnic headache

Annals of Neurology, 2010
AbstractObjectiveHypnic headache (HH) is a rare primary headache disorder characterized by strictly nocturnal headache attacks that mostly occur at the same time at night. The pathophysiology of this disease is poorly understood, but hypothalamic involvement was suspected as the hypothalamus represents the cerebral management center of sleep regulation

A meta-analysis of gray matter volume abnormalities in HIV patients

Psychiatry Research: Neuroimaging, 2023
HIV infection is known to have significant effects on central nervous system. This study conducted a meta-analysis of whole voxel-based morphometry (VBM) in HIV patients (N = 435) and HIV-uninfected controls (N = 397). This study observed a reduction of limbic lobe, cingulate gyrus, frontal lobe, middle frontal gyrus, sub-lobar, insula, inferior ...

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 ...

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 ...

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.

Longitudinal gray-matter volume change in the default-mode network: utility of volume standardized with global gray-matter volume for Alzheimer’s disease: a preliminary study

Radiological Physics and Technology, 2014
Our aim was to show whether sensitivity for detecting volume changes in regional gray matter in default mode network (DMN) at converted [from mild cognitive impairment to Alzheimer's disease (from MCI to AD)] phase was improved by use of a standardized volume with global gray-matter volume.

Cortical thickness, gray matter volume, and white matter anisotropy and diffusivity in schizophrenia

Neuroradiology, 2011
The study was conducted to evaluate simultaneously gray matter changes and white matter changes in patients with schizophrenia.Cortical thickness, gray matter volume, and white matter anisotropy and diffusivity changes in schizophrenic patients (n = 21) were assessed relative to age-, gender-, and parental socioeconomic status-matched healthy controls (

Alterations of Gray Matter Volume and White Matter Integrity in Maternal Deprivation Monkeys

Neuroscience, 2018
Maternal deprivation (MD) in rhesus monkeys has been demonstrated to be an effective model to mimic early adversity in humans because of the close phylogenetic similarity affinity. Although behavioral and hormonal abnormalities have been observed in MD monkeys, the neurobiological underpinning of the long-term deleterious effect of MD on monkeys is ...
