Tract-specific white matter hyperintensities and neuropsychiatric syndromes: a multicentre memory clinic study.
J Neurol Neurosurg Psychiatry
January 2025
Background: White matter hyperintensities (WMH) have been implicated in the pathogenesis of neuropsychiatric symptoms of dementia but the functional significance of WMH in specific white matter (WM) tracts is unclear. We investigate whether WMH burden within major WM fibre classes and individual WM tracts are differentially associated with different neuropsychiatric syndromes in a large multicentre study.
Method: Neuroimaging and neuropsychiatric data of seven memory clinic cohorts through the Meta VCI Map consortium were harmonised.
Background: White matter hyperintensities (WMHs) are established structural imaging markers of cerebral small vessel disease. The pathophysiologic condition of brain tissue varies over the core, the vicinity, and the subtypes of WMH and cannot be interpreted from conventional magnetic resonance imaging. We aim to improve our pathophysiologic understanding of WMHs and the adjacently injured normal-appearing white matter in terms of microstructural and microvascular alterations using quantitative magnetic resonance imaging in patients with sporadic and genetic cerebral small vessel disease.

- NOTCH3cys variants are common and linked to various small vessel diseases, including early-onset stroke and dementia, but there is no comprehensive staging system to assess their severity.
- A cohort study created and validated a simple staging system for NOTCH3-SVD by analyzing data from several international cohorts and the UK Biobank, focusing on the impact of these variants on CVD outcomes and cognition.
- The new system includes 9 disease stages, aiding in understanding the relationship between stages and clinical outcomes like ischemic strokes, cognitive function, and brain damage.
Article Synopsis
- The study aimed to evaluate relationships between three key cerebrovascular functions (blood-brain barrier permeability, vascular pulsatility, and cerebrovascular reactivity) in patients with cerebral small vessel diseases (SVD), including both sporadic cases and a genetic condition known as CADASIL.
- Researchers used advanced brain imaging techniques to analyze these functions in a group of 77 patients, assessing how they relate to SVD severity, subtype, and specific brain changes.
- Findings revealed that worse white matter hyperintensity (WMH) was linked to lower cerebrovascular reactivity and blood plasma volume fraction, with the type of SVD having little impact on these vascular functions after accounting for WMH severity.
Introduction: While incident ischemic lesions (IILs) are not unusual on follow-up magnetic resonance imaging (MRI) following stroke, their risk factors and prognostic significance remain unknown.
Methods: In a prospective multicenter study of 503 acute stroke patients, we assessed IILs on registered MRI images at baseline and 6 months, analyzing risk factors and clinical outcomes across 36 months.
Results: At 6 months, 78 patients (15.
