Despite extensive research over the last decades the clinical significance of white matter lesions (WMLs) is still a matter of debate. Here, we review current knowledge of the correlation between WMLs and cognitive functioning as well as their predictive value for future stroke, dementia, and functional decline in activities of daily living. There is clear(More)
OBJECTIVE We explored cognitive impairment in metabolic syndrome in relation to brain magnetic resonance imaging (MRI) findings. RESEARCH DESIGN AND METHODS We studied 819 participants free of clinical stroke and dementia of the population-based Austrian Stroke Prevention Study who had undergone brain MRI, neuropsychological testing, and a risk factor(More)
BACKGROUND Quantitative susceptibility mapping (QSM) and R2* relaxation rate mapping have demonstrated increased iron deposition in the substantia nigra of patients with idiopathic Parkinson's disease (PD). However, the findings in other subcortical deep gray matter nuclei are converse and the sensitivity of QSM and R2* for morphological changes and their(More)
BACKGROUND AND PURPOSE Elevated concentrations of homocysteine are associated with cerebral small vessel disease (CSVD). B-vitamin supplementation with folate and vitamins B12 and B6 reduces homocysteine concentrations. In a substudy of the VITAmins TO Prevent Stroke (VITATOPS) trial, we assessed the hypothesis that the addition of once-daily supplements of(More)
Cerebral cavernous hemangiomas (CCH) are one of the most frequent vascular malformations in the brain and are often just an incidental finding on neuroimaging. Although CCH bleeding is an important cause of intracerebral hemorrhage (ICH) in younger adults, the spontaneous bleeding risk is generally considered to be low and it is currently not recommended to(More)
BACKGROUND Diagnostic criteria separating vascular dementia from other dementias, particularly Alzheimer's disease (AD) neglect the real world in which most AD cases present with at least some vascular brain lesions. Most importantly, vascular lesions, even if subtle, exert significant effects on the patients' cognitive functioning if they coexist with AD(More)
BACKGROUND AND PURPOSE Magnetization transfer imaging detects cerebral microstructural tissue alterations. We examined the association between the Framingham Stroke Risk Profile (FSRP) score and magnetization transfer imaging (MTI) measures in pathological and normal appearing brain tissue in clinically normal elderly subjects to determine if stroke risk(More)
BACKGROUND AND PURPOSE The presence of anticardiolipin antibodies (aCLs) has been associated with vascular occlusive events. The role of aCLs as a risk factor for stroke has been a matter of debate, and scarce information exists on the relationship between aCLs and other cerebral disorders. Reports exist for seizures, chorea and subtle cognitive(More)
