BACKGROUND Although post-stroke depression is widely recognized, less is known about depressive symptoms in the acute stage of stroke and especially in young stroke patients. We thus investigated depressive symptoms and their determinants in such a cohort. METHODS The Stroke in Young Fabry Patients study (sifap1) prospectively recruited a large(More)
The thalamus comprises numerous nuclei that can be grouped into five major functional domains: (1) the reticular and intralaminar nuclei influence arousal and nociception, (2) sensory nuclei handle afferent pathways, (3) the effector nuclei are involved in motor function and language, (4) associative nuclei participate in higher cognitive functions and (5)(More)
Better-performing younger adults typically express greater brain signal variability relative to older, poorer performers. Mechanisms for age and performance-graded differences in brain dynamics have, however, not yet been uncovered. Given the age-related decline of the dopamine (DA) system in normal cognitive aging, DA neuromodulation is one plausible(More)
BACKGROUND The mismatch between diffusion weighted imaging (DWI) lesion and perfusion imaging (PI) deficit volumes has been used as a surrogate of ischemic penumbra. This pathophysiology-orientated patient selection criterion for acute stroke treatment may have the potential to replace a fixed time window. Two recent trials - DEFUSE and EPITHET -(More)
Functional magnetic resonance data acquired in a task-absent condition ("resting state") require new data analysis techniques that do not depend on an activation model. Here, we propose a new analysis method called Connectivity Concordance Mapping (CCM). The main idea is to assign a label to each voxel based on the reproducibility of its whole-brain pattern(More)
BACKGROUND Stroke is associated with a considerable burden of disease worldwide. Data about prevalence needs regular updating to facilitate health care planning and resource allocation. The purpose of the present study was to determine stroke prevalence in a large urban population in an easy and reliable way. METHODS In a population survey a total of(More)
The 36-item short-form health survey (SF-36) is one of the most commonly used health status instruments in patients with cerebrovascular disease. However, responsiveness to change in health-related quality of life (HRQoL) has not yet been assessed for the SF-36 and its shortened version, the SF-12. The main objective of the present study was to determine(More)
For longitudinal studies in patients suffering from cerebrovascular diseases the poor reproducibility of perfusion measurements via dynamic susceptibility-weighted contrast-enhanced MRI (DSC-MRI) is a relevant concern. We evaluate a novel algorithm capable of overcoming limitations in DSC-MRI caused by partial volume and saturation issues in the arterial(More)
A patient with a circumscribed infarction of the right paramedian thalamus developed a tremor of both eyelids on voluntary eye closure. Co-registration of the magnetic resonance image to a stereotactic atlas of the human thalamus revealed that the lesion was confined to a small subgroup of paramedian nuclei, including the parvocellular part of the(More)
OBJECTIVES The present study aimed to evaluate the frequency of warning signs in younger patients with stroke with a special regard to the 'FAST' scheme, a public stroke recognition instrument (face, arm, speech, timely). SETTING Primary stroke care in participating centres of a multinational European prospective cross-sectional study (Stroke in Young(More)
