Neurotrophins like brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) are thought to play an important role in neuronal repair and plasticity. Recent experimental evidence suggests neuroprotective effects of these proteins in multiple sclerosis (MS). We investigated the response of serum NGF and BDNF concentrations to standardized acute(More)
OBJECTIVE Depression and fatigue are among the most common symptoms of multiple sclerosis (MS). These symptoms frequently co-occur and partially overlap in MS but their underlying biological substrates are unclear. In this study, the relative role of cytokines and hypothalamic-pituitary-adrenal (HPA) axis activity in depression and fatigue were examined in(More)
In recent years it has become clear that multiple sclerosis (MS) patients benefit from physical exercise as performed in aerobic training but little is known about the effect on functional domains and physiological factors mediating these effects. We studied immunological, endocrine and neurotrophic factors as well as coordinative function and quality of(More)
We investigated electrophysiological correlates of fatigue in patients with multiple sclerosis (MS). Transcranial magnetic stimulation (TMS) was used to explore motor excitability in three groups of subjects: MS patients with fatigue (MS-F), MS patients without fatigue (MS-NF) and healthy control subjects. All participants had to perform a fatiguing(More)
Multiple sclerosis is a heterogeneous disease with varying clinical picture. There have been substantial efforts to develop outcome measurements for therapeutic interventions but very few studies have addressed the value of bodily functions from the patient perspective. In a randomly selected cohort of early (<5 years, n=84) and longer lasting disease(More)
Patient self-report health measures have received increasing recognition as supplementary outcome parameters in multiple sclerosis (MS). Given the high prevalence of cognitive problems in this population, reliability and validity of self-report instruments in patient groups with cognitive impairment is essential, especially when using such scales(More)
We tested the hypothesis that the type of vascular occlusion, recanalisation and collateralisation are predictive of outcome after thrombolytic therapy in acute ischaemic stroke. We carried out angiography and local intra-arterial (97) or systemic (14) thrombolysis within 6 h of the onset in patients with an ischaemic stroke in the territory of the internal(More)
BACKGROUND Fatigue is a major complaint of multiple sclerosis (MS) patients. However, little is known about its pathophysiological mechanisms. Evidence from chronic fatigue syndrome and studies on sickness behaviour suggest that immune and neuroendocrine factors may play a causative role in the development of fatigue. METHODS We compared whole blood(More)
Cognitive impairment is one of the most frequent symptoms in patients with multiple sclerosis (MS) but its underlying mechanisms are poorly understood. A number of pathogenetic correlates have previously been proposed including psychosocial factors (such as depression and fatigue), inflammation, neurodegeneration, and neuroendocrine dysregulation. However,(More)
Disease progression in multiple sclerosis (MS)--an inflammatory demyelinating and neurodegenerative disease with a presumed T-cell driven autoimmune origin--has long been hypothesized to be associated with stress. However, this notion has only recently been supported by prospective clinical studies. Several clinical and molecular studies in MS and its(More)
