White matter hyperintensities (WMH) is a non-specific term that refers to white matter (WM) signal hyperintensity areas on T2 weighted MRI scans, and correlates with WM rarefaction (leucoaraiosis) as defined on CT scans. 1 The main risk factors associated with development of WMH are older age and blood hypertension. 2 WMH occur both in demented patients and in healthy elderly subjects, and their relevance to cognitive status has not been fully established.
Background: White matter hyperintensities, prevalent in patients with Parkinson's disease (PD), significantly affect parkinsonian motor symptoms. The objective of this study was to investigate the relationship between white matter hyperintensities and nigrostriatal dopamine depletion and their interaction or mediating effects on motor symptoms in patients with drug-naive early-stage PD.

However, their significance and correlation to migraine disease burden remain unclear. This study aims to examine the correlation of WMHs with migraine features and explore the relationship between WMHs and migraine prognosis. Methods A total of 69 migraineurs underwent MRI scans to evaluate WMHs For executive functions, neither the participants with depression within the first white matter hyperintensities tertile group (z-score difference −0.28, 95% CI −1.45 to 0.91, P = 0.643) nor those within the second white matter hyperintensities tertile differed from the reference group (z-score difference −0.77, 95% CI −2.18 to 0.64, P = 0.276; test for interaction: b = −0.50, 95% CI Objective To test the hypotheses that hypertension and nocturnal blood pressure are related to white matter hyperintensity (WMH) volume, an MRI marker of small vessel cerebrovascular disease, and that WMH burden statistically mediates the association of hypertension and dipping status with memory functioning, we examined the relationship of hypertension and dipping status on WMH volume and White matter hyperintensities are thought to be caused by small vessel infarcts (restriction in blood flow) in the white matter and ultimately result in impairment of brain functions, such as cognition, balance and gait, that depend on complicated interactions between regions. 11.

2021-04-17 · White matter hyperintensities (WMH) is a non-specific term that refers to white matter (WM) signal hyperintensity areas on T2 weighted MRI scans, and correlates with WM rarefaction (leucoaraiosis) as defined on CT scans.
Cognitive effects
White matter diseases include a wide spectrum of disorders that have in common impairment of normal myelination, either by secondary destruction of previously myelinated structures (demyelinating processes) or by primary abnormalities of myelin formation (dysmyelinating processes). Background: White matter hyperintensities of presumed vascular origin (WMH) are one of the imaging features of cerebral small vessel disease. Controversies persist about the effects of WMH on cognitive dysfunction. White matter hyperintensities (WMHs),detected on T2-weighted Fluid-Attenuated Inversion Recovery (FLAIR) sequence on brain magnetic resonance imaging (MRI),are presumed to be the result of chronic hypoperfusion of the white matter and disruption of the blood–brain barrier, leading to chronic leakage of plasma into the white matter [9,10]. Abbreviations: WMH, white matter hyperintensities; PVH, periventricular hyperintensities; DWMH, deep subcortical white matter hyperintensities. Statistical analysis The characteristics of our study were summarized using means and standard deviations (SD) for continuous variables and frequencies and percentages (%) for categorical variables. 12.1 Introduction.
