CONTEXT Tardive dyskinesia (TD) is a common and potentially disabling disorder induced by use of antipsychotic drugs for which medical treatment often gives disappointing results. OBJECTIVE To assess the efficacy of bilateral deep brain stimulation of the internal part of the globus pallidus to treat severe TD. DESIGN Prospective phase 2 multicenter(More)
During the pre-surgical evaluation of drug-resistant epilepsy, the assessment of the extent of the epileptogenic zone and its organization is a crucial objective. Indeed, the epileptogenic zone may be organized as a simple focal lesional site or as a more complex network (often referred to as the 'epileptogenic network') extending beyond the lesion. This(More)
The aim of this study was to assess the outcome of nonmotor fluctuations (NMF) after chronic Subthalamic nucleus (STN) Deep Brain Stimulation (DBS) in Parkinson's disease(PD). Chronic stimulation of the STN has proved to be an effective treatment for advanced PD with motor complications. The outcome of NMF, which are also disabling, remains unknown.(More)
According to most existing literature, the absence of an MRI lesion is generally associated with poorer prognosis in resective epilepsy surgery. Delineation of the epileptogenic zone (EZ) by intracranial recording is usually required but is perceived to be more difficult in 'MRI negative' cases. Most previous studies have used subdural recording and there(More)
Human mesial temporal lobe epilepsies (MTLE) are the most frequent form of partial epilepsies and display frequent pharmacoresistance. The molecular alterations underlying human MTLE remain poorly understood. A two-step transcriptional analysis consisting in cDNA microarray experiments followed by quantitative RT-PCR validations was performed. Because the(More)
Intrathecal morphine (ITM) is commonly used for the treatment of cancer pain. There is reluctance for its use in France to treat chronic noncancer pain. In order to appreciate its popularity, efficacy, dose escalation with time, and long-term tolerance, we carried out a retrospective study in the neurosurgery departments of university teaching hospitals in(More)
BACKGROUND The modulation of extracellular adenosine concentration by opioids provides evidence that the antinociceptive effects of these compounds involve endogenous adenosine. The aim of this study was to determine whether there is a relation between the inhibition of brain synaptosome adenosine uptake by opioid agonists and the analgesic effects of these(More)
