Migraine and white matter hyperintensities

Current Pain and Headache Reports, 2005
Patients with migraine are at increased risk for white matter hyperintensities detected on magnetic resonance imaging. The presence of nonspecific white matter hyperintensities may cause uncertainty for physicians and anxiety for patients. The pathophysiology and long-term consequences of these lesions are unknown. Occasionally, white matter lesions in

White matter hyperintensities in dementia: Does it matter?

Magnetic Resonance Imaging, 1994
The aim of the study was to investigate whether the regional distribution of white matter hyperintensities (WMH) observed by magnetic resonance imaging differed between vascular dementia and patients with late onset Alzheimer's disease. Another aim was to investigate the relations between the occurrence and degree of WMH and clinical and laboratory ...

White matter hyperintensities and chronicity of depression

Journal of Psychiatric Research, 2005
White matter hyperintensities (WMHs) on T(2)-weighted magnetic resonance imaging (MRI) of the brain are associated with advanced age and late-life depression. Most investigations predominantly found these lesions in frontal lobe and basal ganglia supporting the hypothesis of a fronto-striatal dysfunction in depression.

Neuropathologic correlates of white matter hyperintensities

Neurology, 2008
White matter hyperintensities (WMH) are commonly seen on neuroimaging scans, but their underlying histopathologic substrate is unclear. The aim of this work was to establish the pathologic correlates of WMH in unselected elderly cases using two study designs.

Impact of white matter hyperintensities on surrounding white matter tracts

Neuroradiology, 2018
It is unclear how white matter hyperintensities disrupt surrounding white matter tracts. The aim of this tractography study was to determine the spatial relationship between diffusion characteristics along white matter tracts and the distance from white matter hyperintensities.Diffusion tensor 3-T MRI scans were acquired in 29 participants with white ...

White Matter Hyperintensities

Neurology, 2021
The management of white matter hyperintensities (WMH) of presumed vascular origin is a common challenge in neurologic clinical practice. Such lesions may be identified incidentally during workup for common neurologic complaints such as headaches. In addition, they may be observed on imaging performed as part of stroke assessment and management or as ...

White matter volumes and periventricular white matter hyperintensities in aging and dementia

Neurology, 2000
To determine the relationship between MRI periventricular white matter hyperintensities, cerebral white matter volumes, neuropathologic findings, and cognitive status in aged individuals.The significance of periventricular white matter hyperintensities seen on MR images in aged individuals remains controversial.

Abdominal fatness and cerebral white matter hyperintensity

Journal of the Neurological Sciences, 2019
Although obesity has been proven as a risk factor of metabolic and cardiovascular diseases, there have been few studies addressing the association between obesity and cerebral white matter hyperintensity (WMH) volume with controversial findings.

White matter hyperintensities and their dynamic nature: diffusion MRI analysis of white matter hyperintensity regression

ISMRM Annual Meeting, 2023
White matter hyperintensities (WMH) have been shown to progress over time but they might regress too. Little is known about the regression of WMH as the main focus has been on progression. We investigate WMH regression and their dynamic properties using diffusion MRI.

White Matter Hyperintensities and Cognition

2005
Despite the well-established relationship between cerebrovascular disease (CVD) and cognitive decline, confusion remains regarding the clinical importance of the white matter hyperintensities (WMH), also called leukoaraiosis (1), that frequently appear on neuroimaging.
