Deep White Matter Hyperintensity Is Associated With the Dilation of Perivascular Space [PDF]

Journal of Cerebral Blood Flow and Metabolism, 2021
Understanding the pathophysiology of white matter hyperintensity (WMH) is necessary to reduce its harmfulness. Dilated perivascular space (PVS) had been found related to WMH. In the present study, we aimed to examine the topological connections between WMH and PVS, and to investigate whether increased interstitial fluid mediates the correlation between

Occipital Deep White Matter Hyperintensity as Seen by MRI: 1. Clinical Significance

Brain and Development, 1992
Magnetic resonance imaging was performed in 270 patients with various neurologic complaints (1-15Y) with a 0.5 tesla superconducting imaging system using a field echo T1-weighted sequence and spin echo T2-weighted and PD-weighted sequences. Twenty-seven of them had deep white matter hyperintensity (DWMH) in the occipital lobe on T2-weighted images. The

MRI Deep white matter hyperintensity in a psychiatric population

Biological Psychiatry, 1991
The authors evaluated magnetic resonance imaging (MRI) of deep white matter hyperintensity (DWMH) in 90 adult psychiatric inpatients in whom MRIs were clinically indicated and 25 age-matched, medically healthy controls. Forty-two percent of the psychiatric patients and 12% of the controls had evidence of DWMH on MRI. Both incidence and severity of DWMH

Cerebrovascular reactivity as a determinant of deep white matter hyperintensities in migraine

Neurology, 2019
To evaluate the association between the cerebrovascular reactivity to carbon dioxide (CO2-CVR) and the deep white matter hyperintensity (WMH) burden in patients with migraine.A total of 86 nonelderly patients with episodic migraine without vascular risk factors and 35 headache-free controls underwent 3T MRI.

Cortical thinning related to periventricular and deep white matter hyperintensities

Neurobiology of Aging, 2012
Previous studies showed that white matter hyperintensities (WMH) are related to cognitive decline in patients with mild cognitive impairment (MCI) or dementia. Moreover, periventricular WMH (periventricular white matter hyperintensities (PWMH)) and deep WMH (deep white matter hyperintensities (DWMH)) may have different effects on cognition. The purpose
