Factors Associated With the Dilation of Perivascular Space in Healthy Elderly Subjects

Frontiers in Aging Neuroscience, 2021
Background: The dilation of perivascular space (PVS) has been widely used to reflect brain degeneration in clinical brain imaging studies. However, PVS characteristics exhibit large differences in healthy subjects.

Global and regional associations of smaller cerebral gray and white matter volumes with gait in older people. [PDF]

PLoS ONE, 2014
BACKGROUND: Gait impairments increase with advancing age and can lead to falls and loss of independence. Brain atrophy also occurs in older age and may contribute to gait decline. We aimed to investigate global and regional relationships of cerebral gray

Calendar age and puberty-related development of regional gray matter volume and white matter tracts during adolescence [PDF]

, 2021
Background Adolescence is a critical time for brain development. Findings from previous studies have been inconsistent, failing to distinguish the influence of pubertal status and aging on brain maturation.

Differential Impact of Cognitive Impairment in MCI Patients: A Case-Based Report

Case Reports in Neurology, 2020
Mild cognitive impairment (MCI) traditionally refers to an intermediate stage between healthy individuals and early Alzheimer disease. Evidence shows grey and white matter volume changes and decrease in several executive functions, albeit the relation ...

APPLICATION OF STEREOLOGICAL METHODS TO STUDY THE WHITE MATTER AND MYELINATED FIBERS THEREIN OF RAT BRAIN

Image Analysis and Stereology, 2011
An efficient and unbiased stereological method was applied to estimate the white matter volume, the total volume, total length and mean diameter of the myelinated fibers in the white matter and the total volume of the myelin sheaths in the white matter ...

Regional distribution of white matter hyperintensities in vascular dementia, Alzheimer's disease and healthy aging [PDF]

, 2004
Background: White matter hyperintensities (WMH) on MRI scans indicate lesions of the subcortical fiber system. The regional distribution of WMH may be related to their pathophysiology and clinical effect in vascular dementia (VaD), Alzheimer's disease ...

White matter volume abnormalities and associations with symptomatology in schizophrenia [PDF]

Psychiatry Research: Neuroimaging, 2010
The cerebral white matter (WM) is critically involved in many bio-behavioral functions impaired in schizophrenia. However, the specific neural systems underlying symptomatology in schizophrenia are not well known. By comparing the volume of all brain fiber systems between chronic patients with DSM-III-R schizophrenia (n=88) and matched healthy ...
