Abstract

Objective Evidence is mixed as to whether periventricular or deep white matter hyperintensities (WMHs) increase the risk for depressive symptoms, partly because of heterogeneity in depression measurement, short follow-up, and confounding by prodromal dementia. The study objective was to evaluate WMH volume in relation to discrete depressive symptoms over 10 years, stratifying by incident depression and dementia. Methods In this prospective longitudinal cohort study of a representative population sample from Dijon, France, 1,440 participants aged 65–80 years (median age: 72 years; 59.5% women) without depression, dementia, or stroke at baseline were studied. Baseline T2-weighted images were obtained in a 1.5-T scanner to quantify WMHs (log cm 3 ). Clinic visits were performed up to five times in a 10-year period to assess incident neurologic diseases and comorbidities. Depressive symptoms were measured with the Center for Epidemiologic Studies Depression Scale and converted to factor z scores, representing somatic symptoms, depressed affect, low positive affect, and interpersonal problems. Results Periventricular WMH volume was uniquely associated with low positive affect among incident depression cases (β = 0.15; 95% confidence interval [CI]: 0.02–0.29; p = 0.026). Deep WMH volume was uniquely associated with depressed affect among incident dementia cases (β = 0.36; 95% CI: 0.05–0.68; p = 0.025). WMH volume (periventricular, deep, and total) was associated with interpersonal problems among persons who developed dementia with depression. Conclusion The findings highlight that regional WMH volumes and specific depressive symptoms have clinical and prognostic relevance to help differentiate between persons at risk for depression and dementia.

Abstract

Background and Purpose— We examined the association of white-matter hyperintensity (WMH) volume and covert brain infarcts, which are the 2 major magnetic resonance imaging markers of covert cerebrovascular disease in older adults, with long-term risk of ischemic stroke and intracerebral hemorrhage (ICH) in the general population. Methods— Participants were 1731 individuals aged ≥65 years from the Three-City Dijon study. We studied the association of WMH volume and brain infarct, with incident ischemic stroke overall, and by subtype, and with incident ICH. Results— High total, periventricular, and deep WMHs were associated with incident ICH. Extensive periventricular WMH volume was associated with increased risk of ischemic stroke (hazard ratio, 1.94; 95% confidence interval, 1.12–3.35), particularly cardioembolic stroke. Covert brain infarcts were associated with incident ICH but not with incident ischemic stroke or its subtypes. Conclusions— Although of ischemic nature, both WMH volume and covert brain infarcts portend a major risk of ICH. If confirmed in independent studies, these findings could have important implications for the clinical management of covert vascular brain lesions.

Abstract

International audience; Cerebral β-amyloid (Aβ) deposition and atrophy are central features of Alzheimer disease. Studies of Alzheimer disease biomarkers have largely focused on Aβ in cerebrospinal fluid (CSF), and there is uncertainty as to what plasma Aβ may be a marker. We examined the association of Aβ levels in the plasma with magnetic resonance imaging (MRI)-markers of brain aging, including longitudinal changes in global and regional brain volumes, in dementia-free persons. We studied 1530 participants of the Three-City-Dijon cohort, aged 65-80 years. Plasma Aβ measurement and magnetic resonance imaging were performed at baseline and after a 4-year follow up. Total brain, gray matter, and hippocampal volume were estimated using voxel-based morphometry, and annualized change in brain volumes was calculated. Increased plasma Aβ1-40 was associated with lower baseline hippocampal volume. Although baseline plasma Aβ levels were not associated with longitudinal change in brain volumes, consistently high plasma Aβ1-40 levels were associated with faster total brain atrophy and consistently low plasma Aβ1-42/Aβ1-40 ratio, with increased total brain atrophy and gray matter atrophy. In dementia-free older adults, high plasma Aβ1-40 and low plasma Aβ1-42/Aβ1-40 ratio were associated with smaller hippocampal volume and accelerated global and regional brain atrophy respectively.

Abstract

International audience; INTRODUCTION:The purpose of this study was to study the effect of donepezil on the rate of hippocampal atrophy in prodromal Alzheimer's disease (AD).METHODS:A double-blind, randomized, placebo-controlled parallel group design using donepezil (10 mg/day) in subjects with suspected prodromal AD. Subjects underwent two brain magnetic resonance imaging scans (baseline and final visit). The primary efficacy outcome was the annualized percentage change (APC) of total hippocampal volume (left + right) measured by an automated segmentation method.RESULTS:Two-hundred and sixteen only subjects were randomized across 28 French expert clinical sites. In the per protocol population (placebo = 92 and donepezil = 82), the donepezil group exhibited a significant reduced rate of hippocampal atrophy (APC = -1.89%) compared with the placebo group (APC = -3.47%), P < .001. There was no significant difference in neuropsychological performance between treatment groups.DISCUSSION:A 45% reduction of rate of hippocampal atrophy was observed in prodromal AD following 1 year of treatment with donepezil compared with placebo.

Abstract

Background— The burden of cerebral white matter hyperintensities (WMH) is associated with an increased risk of stroke, dementia, and death. WMH are highly heritable, but their genetic underpinnings are incompletely characterized. To identify novel genetic variants influencing WMH burden, we conducted a meta-analysis of multiethnic genome-wide association studies. Methods and Results— We included 21 079 middle-aged to elderly individuals from 29 population-based cohorts, who were free of dementia and stroke and were of European (n=17 936), African (n=1943), Hispanic (n=795), and Asian (n=405) descent. WMH burden was quantified on MRI either by a validated automated segmentation method or a validated visual grading scale. Genotype data in each study were imputed to the 1000 Genomes reference. Within each ethnic group, we investigated the relationship between each single-nucleotide polymorphism and WMH burden using a linear regression model adjusted for age, sex, intracranial volume, and principal components of ancestry. A meta-analysis was conducted for each ethnicity separately and for the combined sample. In the European descent samples, we confirmed a previously known locus on chr17q25 ( P =2.7×10 −19 ) and identified novel loci on chr10q24 ( P =1.6×10 −9 ) and chr2p21 ( P =4.4×10 −8 ). In the multiethnic meta-analysis, we identified 2 additional loci, on chr1q22 ( P =2.0×10 −8 ) and chr2p16 ( P =1.5×10 −8 ). The novel loci contained genes that have been implicated in Alzheimer disease (chr2p21 and chr10q24), intracerebral hemorrhage (chr1q22), neuroinflammatory diseases (chr2p21), and glioma (chr10q24 and chr2p16). Conclusions— We identified 4 novel genetic loci that implicate inflammatory and glial proliferative pathways in the development of WMH in addition to previously proposed ischemic mechanisms.

Abstract

Whether novel risk variants of Alzheimer's disease (AD) identified through genome-wide association studies also influence magnetic resonance imaging-based intermediate phenotypes of AD in the general population is unclear. We studied association of 24 AD risk loci with intracranial volume, total brain volume, hippocampal volume (HV), white matter hyperintensity burden, and brain infarcts in a meta-analysis of genetic association studies from large population-based samples (N = 8175-11,550). In single-SNP based tests, AD risk allele of APOE (rs2075650) was associated with smaller HV (p = 0.0054) and CD33 (rs3865444) with smaller intracranial volume (p = 0.0058). In gene-based tests, there was associations of HLA-DRB1 with total brain volume (p = 0.0006) and BIN1 with HV (p = 0.00089). A weighted AD genetic risk score was associated with smaller HV (beta +/- SE = -0.047 +/- 0.013, p = 0.00041), even after excluding the APOE locus (p = 0.029). However, only association of AD genetic risk score with HV, including APOE, was significant after multiple testing correction (including number of independent phenotypes tested). These results suggest that novel AD genetic risk variants may contribute to structural brain aging in nondemented older community persons. (C) 2015 Elsevier Inc. All rights reserved.

Abstract

Background Stroke in patients with acute cervical artery dissection may be anticipated by initial transient ischemic or nonischemic symptoms. Aim Identifying risk factors for delayed stroke upon cervical artery dissection. Methods Cervical artery dissection patients from the multicenter Cervical Artery Dissection and Ischemic Stroke Patients study were classified as patients without stroke ( n = 339), with stroke preceded by nonstroke symptoms (delayed stroke, n = 244), and with stroke at onset ( n = 382). Demographics, clinical, and vascular findings were compared between the three groups. Results Patients with delayed stroke were more likely to present with occlusive cervical artery dissection ( P < 0·001), multiple cervical artery dissection ( P = 0·031), and vertebral artery dissection ( P < 0·001) than patients without stroke. No differences were observed in age, smoking, arterial hypertension, hypercholesterolemia, migraine, body mass index, infections during the last week, and trauma during the last month, but patients with delayed stroke had less often transient ischemic attack ( P < 0·001) and local signs (Horner syndrome and cranial nerve palsy; P < 0·001). Conclusions Occlusive cervical artery dissection, multiple cervical artery dissection, and vertebral artery dissection were associated with an increased risk for delayed stroke. No other risk factors for delayed stroke were identified. Immediate cervical imaging of cervical artery dissection patients without ischemic stroke is needed to identify patients at increased risk for delayed ischemia.

Abstract

Erratum in: Familial occurrence and heritable connective tissue disorders in cervical artery dissection. [Neurology. 2016]; International audience; In a large series of patients with cervical artery dissection (CeAD), a major cause of ischemic stroke in young and middle-aged adults, we aimed to examine frequencies and correlates of family history of CeAD and of inherited connective tissue disorders. We combined data from 2 large international multicenter cohorts of consecutive patients with CeAD in 23 neurologic departments participating in the CADISP-plus consortium, following a standardized protocol. Frequency of reported family history of CeAD and of inherited connective tissue disorders was assessed. Putative risk factors, baseline features, and 3-month outcome were compared between groups. Among 1,934 consecutive patients with CeAD, 20 patients (1.0%, 95% confidence interval: 0.6%-1.5%) from 17 families (0.9%, 0.5%-1.3%) had a family history of CeAD. Family history of CeAD was significantly more frequent in patients with carotid location of the dissection and elevated cholesterol levels. Two patients without a family history of CeAD had vascular Ehlers-Danlos syndrome with a mutation in COL3A1. This diagnosis was suspected in 2 additional patients, but COL3A1 sequencing was negative. Two patients were diagnosed with classic and hypermobile Ehlers-Danlos syndrome, one patient with Marfan syndrome, and one with osteogenesis imperfecta, based on clinical criteria only. In this largest series of patients with CeAD to date, family history of symptomatic CeAD was rare and inherited connective tissue disorders seemed exceptional. This finding supports the notion that CeAD is a multifactorial disease in the vast majority of cases.

Abstract

Objective: We investigated the relation of circulating plasma β-amyloid (Aβ) with MRI markers of small vessel disease (SVD) in dementia-free community persons. Methods: Participants were 1,690 individuals aged 65 to 80 years from the Three-City Dijon Study. Plasma Aβ measurement and MRI examination were performed at baseline and after a 4-year follow-up. MRI markers of SVD included white matter hyperintensities (WMH), lacunes, and enlarged perivascular spaces. We examined the relation of plasma Aβ levels with MRI markers of SVD at baseline and with progression of WMH over follow-up (n = 1,057). We also assessed whether these relations were modified by vascular risk factors, notably blood pressure. Results: Low plasma Aβ 1–40 levels were associated with increased progression of WMH, and low Aβ 1–42 with higher odds of extensive WMH progression over the follow-up (odds ratio = 1.66, 95% confidence interval = 1.16–2.38). Consistently low Aβ 1–40 and Aβ 1–42 levels on both measurements were associated with accelerated progression of WMH. These associations were modified by blood pressure levels but not the APOE e4 genotype. Conclusions: Progression of WMH volume in dementia-free older persons is associated with levels of circulating plasma Aβ. These results reinforce the notion of an interrelation of vascular and neurodegenerative mechanisms in cerebral aging.
