The clinical diagnosis of multiple system atrophy (MSA) is fraught with difficulty and there are no pathognomonic features to discriminate the parkinsonian variant (MSA-P) from Parkinson's disease (PD). Besides the poor response to levodopa, and the additional presence of pyramidal or cerebellar signs (ataxia) or autonomic failure as major diagnostic(More)
BACKGROUND Multiple system atrophy (MSA) is a fatal and still poorly understood degenerative movement disorder that is characterised by autonomic failure, cerebellar ataxia, and parkinsonism in various combinations. Here we present the final analysis of a prospective multicentre study by the European MSA Study Group to investigate the natural history of(More)
We present the efficacy and side effects of bilateral deep brain stimulation (DBS) of the subthalamic nuclei (STN) performed with a more simplified surgical procedure than described by the Grenoble group. A consecutive series of 26 patients with advanced and levodopa-responsive Parkinson's disease and motor complications was evaluated using the Unified(More)
The objective of this paper is to evaluate the accuracy of conventional diagnostic criteria for Parkinson's disease and give an overview of alternative causes to parkinsonian syndromes. We also propose a new approach to the clinical diagnosis of Parkinson's disease, which may improve the diagnostic accuracy. The available information on autopsy findings in(More)
Direct genomic DNA sequencing fails to detect epsilon-sarcoglycan (SGCE) mutations in up to 30% of familial myoclonus-dystonia (M-D) cases. We identified novel large heterozygous deletions of SGCE exon 5 or exon 6 in two M-D pedigrees. Like nonsense mutations, exon rearrangements result in the generation of premature stop codons downstream of the deleted(More)
In this Danish-Norwegian randomized double-blind parallel-group multicentre study, we compared the therapeutic response of slow-release Madopar HBS to standard Madopar in 134 de novo patients with idiopathic Parkinson's disease during a 5-year period. The drugs were dosed according to the individual need of the patients. The Webster, NUDS, UPDRS and Hoehn &(More)
In 39 parkinsonian patients, CSF somatostatin content was 88.0 +/- 4.1 pg per milliliter, which was about 40% less than in controls (147.3 +/- 5.1 pg per milliliter). Somatostatin values were unrelated to age, sex, body weight, total CSF protein, immunoglobulin, or cell count in either group. Parkinsonian values were not related to duration of disease,(More)
A defective antioxidant scavenging system plays a major role in one of the theories of the pathogenesis of Parkinson's disease. The aim of this study was to investigate whether there is a general difference in antioxidant activity between early and advanced cases of Parkinson's disease. Twenty five recently diagnosed patients, without any clinical(More)
Cabergoline is a potent D2 receptor agonist with a half-life of 65 hours that may provide continuous dopaminergic stimulation administered once daily. In this study, we randomized de novo Parkinson's disease (PD) patients to treatment with increasing doses of cabergoline (0.25 to 4 mg/d) or levodopa (100 to 600 mg/d) up to the optimal or maximum tolerated(More)
