White matter hyperintensities (WMH) are frequently seen on neuroimaging of elderly and associated with cognitive decline the development dementia. Yet, temporal dynamics conversion normal-appearing white (NAWM) into WMH remains unknown. We examined whether when progression was preceded by changes in fluid-attenuated inversion recovery diffusion tensor imaging values, thereby taking account differences between participants mild versus severe baseline WMH.From 266 RUN DMC study (Radboud...
<b>Background: </b> Subjective cognitive failures (SCF) and subjective memory (SMF) have been reported to be an early predictor of Alzheimer disease (AD) attributed white matter lesions (WML). Since AD is characterized by hippocampal degeneration, it surprising that its relation with atrophy has investigated only sparsely. Previous studies on this are rare, limited in sample size, did not adjust for WML. <b>Objective: To determine the between SCF volume strata objective performance among...
The relation between progression of cerebral small vessel disease (SVD) and gait decline is uncertain, diffusion tensor imaging (DTI) studies on are lacking. We therefore investigated the longitudinal associations (micro) structural brain changes in SVD using DTI. 275 participants were included from Radboud University Nijmegen Diffusion Magnetic resonance Cohort (RUN DMC), a prospective cohort with aged 50-85 years. Gait (using GAITRite) magnetic measures assessed during baseline (2006-2007)...
<h3>Importance</h3> Gait and cognition have been related to mortality in population-based studies. This association is possibly mediated by cerebral small vessel disease (SVD), which has associated with as well. It unknown factors can predict individuals SVD. Identification of high-risk patients may provide insight into that reflect their vital health status. <h3>Objectives</h3> To assess SVD identify potential clinical and/or imaging mortality. <h3>Design, Setting, Participants</h3> A...
The relationship between cerebral small vessel disease (SVD) and dementia has been studied without considering white matter (WM) volume, the microstructural integrity of WM surrounding SVD, grey (GM).We prospectively investigated these structures risk dementia, formed a prediction model to investigate which characteristics (macro- or microstructural) explained most variance.The RUN DMC study is prospective cohort among 503 non-demented participants with an age 50 85 years at baseline,...

We computed properties using graph theory from probabilistic tractography calculated changes psychomotor speed...
To promote shared decision-making (SDM) during discharge planning of patients with stroke, a patient decision aid (PtDA) was implemented in seven Dutch hospitals. This mixed-methods process evaluation assessed: 1) PtDA use, 2) the SDM process, 3) facilitators and barriers influencing health care professional (HCP) adoption PtDA, 4) HCP experiences PtDA. Rates use were derived from hospital registries log data. levels consultations quantitatively assessed using OPTION-5 (score range 0-100);...
White matter hyperintensities (WMH) constitute the visible spectrum of cerebral small vessel disease (SVD) markers and are associated with cognitive decline, although they do not fully account for memory decline observed in individuals SVD. We hypothesize that WMH might exert their effect on indirectly by affecting remote brain structures such as hippocampus. investigated temporal interactions between WMH, hippocampal atrophy older adults Five hundred three participants RUNDMC study...

We screened DWI scans (n = 1,152) for DWI+ lesions, assessed lesion evolution...
Introduction: Cerebral small vessel disease is one of the most important risk factors for dementia, and has been related to hippocampal atrophy, which among first observed changes on conventional MRI in patients with dementia.However, these volumetric might be preceded by loss microstructural integrity hippocampus not sensitive enough.Therefore, we investigated relation between diffusion parameters incident using tensor imaging, independent volume.Methods: The RUNDMC study a prospective 503...
Traditional markers of cerebral small vessel disease (SVD) are related to cognition and cognitive decline, but this relation is weak. Therefore other factors may determine the transition from intact performance such as damage white matter at microstructural level. Little known about association between integrity changes in cognition. In study we investigated baseline change function.503 participants RUN DMC with SVD without dementia, 398 whom (79.1%) underwent repeated testing follow-up, a...
Cerebral small vessel disease (SVD) is a frequent pathology in aging and contributor to the development of dementia. Plasma Aβ (amyloid β) levels may be useful as early biomarker, but role plasma SVD remains elucidated.
