Inferior frontal white matter volume and suicidality in schizophrenia

Psychiatry Research: Neuroimaging, 2008
The neurobiology of suicidality in schizophrenia is largely unknown. We therefore assessed gray and white matter volumes associated with past suicidality and current self-aggression in schizophrenia. Fifty-five outpatients with schizophrenia (n=55) and healthy controls (n=55), matched for age, gender and handedness, were recruited.

White Matter Volume and White/Gray Matter Ratio in Mammalian Species as a Consequence of the Universal Scaling of Cortical Folding [PDF]

Proceedings of the National Academy of Sciences of the United States of America, 2019
Because the white matter of the cerebral cortex contains axons that connect distant neurons in the cortical gray matter, the relationship between the volumes of the 2 cortical compartments is key for information transmission in the brain.

Effects of Age on Volumes of Cortex, White Matter and Subcortical Structures

Neurobiology of Aging, 2005
The effect of age was investigated in and compared across 16 automatically segmented brain measures: cortical gray matter, cerebral white matter, hippocampus, amygdala, thalamus, the accumbens area, caudate, putamen, pallidum, brainstem, cerebellar cortex, cerebellar white matter, the lateral ventricle, the inferior lateral ventricle, and the 3rd and ...

Volume of White Matter Hyperintensities, and Cerebral Micro-Bleeds

Journal of Stroke and Cerebrovascular Diseases, 2021
In the past years the significance of white matter hyperintensities (WMH) has gained raising attention because it is considered a marker of severity of different pathologies. Another condition that in the last years has been assessed in the neuroradiology field is cerebral microbleeds (CMB).

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 ...

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.
