An ambulatory gait analysis method using body-attached gyroscopes to estimate spatio-temporal parameters of gait has been proposed and validated against a reference system for normal and pathologic gait. Later, ten Parkinson's disease (PD) patients with subthalamic nucleus deep brain stimulation (STN-DBS) implantation participated in gait measurements using(More)
The identification of genetic causes for Mendelian disorders has been based on the collection of multi-incident families, linkage analysis, and sequencing of genes in candidate intervals. This study describes the application of next-generation sequencing technologies to a Swiss kindred presenting with autosomal-dominant, late-onset Parkinson disease (PD).(More)
An ambulatory system for quantification of tremor and bradykinesia in patients with Parkinson's disease (PD) is presented. To record movements of the upper extremities, a sensing units which included miniature gyroscopes, has been fixed to each of the forearms. An algorithm to detect and quantify tremor and another algorithm to quantify bradykinesia have(More)
OBJECTIVE To study the reappearance of the clinical signs of PD when subthalamic nucleus (STN) deep brain stimulation (DBS) was turned off. METHOD The authors studied 35 patients treated with STN DBS 6.7 +/- 3.3 months (mean +/- SD) after implantation. All were clinically improved. Twenty-four had not required any antiparkinsonian medication for many(More)
No biological marker is currently available for the routine diagnosis of stroke. The aim of this pilot study was to determine whether heart-fatty acid binding protein (H-FABP) could be used as a valid diagnostic biomarker for stroke, as compared with neuron-specific enolase (NSE) and S100B proteins. Using two-dimensional gel electrophoresis separation of(More)
OBJECTIVE To report the study of a multigenerational Swiss family with dopa-responsive dystonia (DRD). METHODS Clinical investigation was made of available family members, including historical and chart reviews. Subject examinations were video recorded. Genetic analysis included a genome-wide linkage study with microsatellite markers (STR), GTP(More)
We report on 4 new cases of valvular heart disease in Parkinson's disease patients treated with the ergot derivative dopamine agonists pergolide and cabergoline. Noninflammatory fibrotic degeneration of cardiac valves has been reported to occur in patients with carcinoid syndrome and to occasionally complicate therapies with the anti-migraine ergot alkaloid(More)
BACKGROUND AND PURPOSE Brain MR imaging is routinely performed in the work-up of suspected PD, yet its role is essentially limited to the exclusion of other pathologies. We performed a pattern-recognition analysis based on DTI data to detect subjects with PD at the individual level. MATERIALS AND METHODS We included 40 consecutive patients with(More)
The diagnosis of Alzheimer's disease (AD), the most common form of dementia in the general population, usually relies upon the presence of typical clinical features and structural changes on brain magnetic resonance imaging. Over the last decade, a number of biological abnormalities have been reported in the cerebrospinal fluid (CSF) of AD patients, in(More)
Early diagnosis and immediate therapeutic interventions are crucial factors to reduce the damage extent and the risk of death. Currently, the diagnosis of stroke relies on neurological assessment of the patient and neuro-imaging techniques including computed tomography and/or magnetic resonance imaging scan. An early diagnostic marker of stroke, ideally(More)
