Objective To examine the relationship between white matter hyperintensities and headache. Methods White matter hyperintensities burden was assessed semi-quantitatively using Fazekas and Scheltens scales, and by manual and automated volumetry of MRI in a sub-study of the general population-based Nord-Trøndelag Health Study (HUNT MRI). Using validated questionnaires, participants were categorized into four cross-sectional headache groups: Headache-free (n = 551), tension-type headache (n = 94), migraine (n = 91), and unclassified headache (n = 126). Prospective questionnaire data was used to further categorize participants into groups according to the evolution of headache during the last 12 years: Stable headache-free, past headache, new onset headache, and persistent headache. White matter hyperintensities burden was compared across headache groups using adjusted multivariate regression models. Results Individuals with tension-type headache were more likely to have extensive white matter hyperintensities than headache-free subjects, with this being the case across all methods of white matter hyperintensities assessment (Scheltens scale: Odds ratio, 2.46; 95% CI, 1.44–4.20). Migraine or unclassified headache did not influence the odds of having extensive white matter hyperintensities. Those with new onset headache were more likely to have extensive white matter hyperintensities than those who were stable headache-free (Scheltens scale: Odds ratio, 2.24; 95% CI, 1.13–4.44). Conclusions Having tension-type headache or developing headache in middle age was linked to extensive white matter hyperintensities. These results were similar across all methods of assessing white matter hyperintensities. If white matter hyperintensities treatment strategies emerge in the future, this association should be taken into consideration.

Abstract Background: Although homocysteine (Hcy) and white matter hyperintensities (WMH) have been proven to be correlated with increased risks of ischemic stroke, there have been few studies addressing the association between serum Hcy and WMH in a population with asymptomatic intracranial arterial stenosis (aICAS). Thus, the aim of the present study is to describe the association between Hcy and WMH in rural-dwelling Chinese people with aICAS. Methods: In this study, 150 participants diagnosed as aICAS by magnetic resonance angiography were recruited from the Kongcun Town Study, which was a population-based study aimed to investigate the prevalence of aICAS in general population aged 40 to 90 years old, free of ischemic stroke history, and living in the Kongcun town, Pingyin county, Shandong, China. Data on demographics, risk factors, and serum Hcy levels were collected via interview, clinical examination, and laboratory tests. The WMH volumes were calculated through the lesion segmentation tool system for the Statistical Parametric Mapping package based on magnetic resonance imaging. The association between Hcy and WMH volume was analyzed using both linear and logistic regression analysis. Results: After adjusting for all confounders, high Hcy (HHcy) (serum Hcy ≥15umol/L) was significantly associated with severe WMH (the highest quartile in WMH volume) (OR: 2.972, 95%CI: 1.017-7.979, P <0.05). However, with changing of WMH volumes, only trends towards association with HHcy were observed in all 3 models (P values only slightly exceeded 0.05). After being stratified by age, sex, or ever smoking, the association between HHcy and WMH became more significant in participants who were ≥60 years old, male, or ever smoker. Conclusions: HHcy is associated with severe WMH in rural-dwelling Chinese people with aICAS, especially in participants ≥60 years old, male participants, or ever smokers, indicating these may be risk factors that contribute to the association between HHcy and severe WMH.

The Relationship

We examined the relationship between white matter hyperintensities (WMH) and cortical neurodegeneration in cerebral small vessel disease (CSVD) by investigating whether cortical thickness is a remote effect of WMH through structural fiber tract connectivity in a population at increased risk of CSVD. We measured cortical thickness on T1-weighted images and segmented WMH on FLAIR images in 930 participants of a population-based cohort study at baseline. DWI-derived whole-brain probabilistic tractography was used to define WMH connectivity to cortical regions. Linear mixed-effects models were applied to analyze the relationship between cortical thickness and connectivity to WMH. Factors associated with cortical thickness (age, sex, hemisphere, region, individual differences in cortical thickness) were added as covariates. Median age was 64 [IQR 46–76] years. Visual inspection of surface maps revealed distinct connectivity patterns of cortical regions to WMH. WMH connectivity to the cortex was associated with reduced cortical thickness ( p = 0.009) after controlling for covariates. This association was found for periventricular WMH ( p = 0.001) only. Our results indicate an association between WMH and cortical thickness via connecting fiber tracts. The results imply a mechanism of secondary neurodegeneration in cortical regions distant, yet connected to subcortical vascular lesions, which appears to be driven by periventricular WMH.

Vessel Disease

White matter hyperintensities (WMHs) of presumed vascular origin are a frequent finding in cerebral magnetic resonance imaging of older people. They are attributed to small vessel disease and involved in the pathogenesis of cognitive decline. Since vascular risk factors, especially arterial hypertension, predispose to small vessel disease, we analyzed the association of systolic blood pressure (SBP), diastolic blood pressure (DBP), and antihypertensive medications with WMH volume in 560 participants of the 1000BRAINS study, drawn from the population-based Heinz Nixdorf Recall study (65.2±7.5 years; 51.4% men). Further, we analyzed treatment efficacy using a classification of 6 BP treatment groups defined by antihypertensive medication and level of BP: (1) untreated BP <120/<80 mm Hg, (2) untreated SBP 120 to 139 or DBP 80 to 89 mm Hg, (3) untreated BP ≥140 or ≥90 mm Hg, (4) treated BP <120/<80 mm Hg, (5) treated SBP 120 to 139 or DBP 80 to 89 mm Hg, and (6) treated BP ≥140 or ≥90 mm Hg. Median WMH volume (Q1–Q3) was 4.6 (3.0–7.8) cm 3 ; mean±SD of SBP and DBP was 128.6±17.4 and 76.1±9.8 mm Hg. In multivariable linear regression models, continuous SBP (β=0.63 cm 3 per 10 mm Hg [95% CI, 0.32–0.94]), DBP (0.64 cm 3 per 5 mmHg [95% CI, 0.37–0.91]), and antihypertensive treatment (1.23 cm 3 [95% CI, 0.14–2.23]) were significantly associated with WMH volume. Regarding treatment efficacy, only participants with hypertension despite treatment (treated BP ≥140 or ≥90 mm Hg) had significantly increased WMH volume (4.24 cm 3 [2.36–6.13]) compared with normotension without treatment (untreated BP <120/<80 mm Hg). Our results suggest that WMHs represent a marker of advanced hypertension pathology. Hence, early treatment should prevent WMHs.

Abstract Background The contribution of cerebral small vessel disease (cSVD) to the pathogenesis of frailty remains uncertain. We aimed to examine the associations between cSVD with progression of frailty in a population-based study of older people. Methods People aged between 60 and 85 years were randomly selected form the electoral roll to participate in the Tasmanian Study of Cognition and Gait. Participants underwent self-reported questionnaires, objective gait, cognitive and sensorimotor testing over three phases ranging between 2005 and 2012. These data were used to calculate a 41-item frailty index (FI) at three time points. Baseline brain magnetic resonance imaging was performed on all participants to measure cSVD. Generalized mixed models were used to examine associations between baseline cSVD and progression of frailty, adjusted for confounders of age, sex, level of education, and total intracranial volume. Results At baseline (n = 388) mean age was 72 years (SD = 7.0), 44% were female, and the median FI score was 0.20 (interquartile range [IQR] 0.12, 0.27). In fully adjusted models higher burden of baseline white matter hyperintensity (WMH) was associated with frailty progression over 4.4 years (β = 0.03, 95% CI: 0.01, 0.05; p = .004) independent of other SVD markers. Neither baseline infarcts (p = .23), nor microbleeds at baseline (p = .65) were associated with progression of frailty. Conclusions We provide evidence for an association between baseline WMHs and progression of frailty. Our findings add to a growing body of literature suggesting WMH is a marker for frailty.
