OBJECTIVE (1) To determine if there are changes in event-related desynchronization/event-related synchronization (ERD/ERS) patterns when the movement is sustained? (2) To determine, from a technical point of view for ERD calculation, if it is possible to take the reference period during muscular activation? METHODS Eight healthy subjects performed two(More)
OBJECTIVE Abnormal low- and high-frequency oscillatory activities have been linked to abnormal movement control in Parkinson's disease. We aimed to study how low- and high-frequency oscillatory activities are modulated by movement in the contralateral and ipsilateral subcorticocortical loops. METHODS We studied mu, beta and gamma rhythm event-related(More)
The objective of this study was to use the Lille Apathy Rating Scale to assess apathy in a large population of Parkinson's disease (PD) patients and identify several different apathy profiles. One hundred fifty-nine patients with probable PD and 58 healthy controls participated in the study. Apathy was assessed using the Lille Apathy Rating Scale. Motor,(More)
BACKGROUND Pathophysiological mechanisms involved in amyotrophic lateral sclerosis (ALS) are complex and none has identified reliable markers useful in routine patient evaluation. The aim of this study was to analyze the CSF of patients with ALS by (1)H NMR (Nuclear Magnetic Resonance) spectroscopy in order to identify biomarkers in the early stages of the(More)
The purpose of this paper is to describe the effect of 5 years of subthalamic nucleus deep brain stimulation (STN DBS) on levodopa-induced complications, both in everyday life and during an acute challenge with levodopa. Thirty three patients were evaluated during an acute levodopa challenge before surgery and then 1 and 5 years afterwards (both off stim(More)
AIMS The pathophysiological role of iron in Parkinson's disease (PD) was assessed by a chelation strategy aimed at reducing oxidative damage associated with regional iron deposition without affecting circulating metals. Translational cell and animal models provided concept proofs and a delayed-start (DS) treatment paradigm, the basis for preliminary(More)
Sir, In 2007, we described the clinical features and natural history of neuroferritinopathy in 41 patients defined at the molecular genetic level by the presence of EcoN1 restriction digestion site in exon 4 of FTL (also referred to as FTL1), the gene coding for the ferritin light polypeptide (Chinnery et al., 2007). Three French patients in our paper(More)
The studies of duodenal infusion of a levodopa on small groups of parkinsonian patients have reported beneficial effects on motor complications. However, little is known about the patient profile and indications for duodenal levodopa infusion. The purpose of this study is to exhaustively investigate the clinical characteristics of the population and(More)
Apathy is characterized by lack of interest, loss of initiative, and flattening of affect. It is a frequent, very disabling nonmotor complication of Parkinson's disease (PD). The condition may notably occur when dopaminergic medications are tapered after the initiation of subthalamic stimulation and thus can be referred to as "dopaminergic apathy." Even in(More)
BACKGROUND Benign hereditary chorea (BHC) is a rare autosomal dominant disorder characterised by childhood onset that tends to improve in adulthood. The associated gene, NKX2-1 (previously called TITF1), is essential for organogenesis of the basal ganglia, thyroid and lungs. The aim of the study was to refine the movement disorders phenotype. We also(More)
