We sought to define the influence of ageing in clinical, cognitive, and quality-of-life outcomes after subthalamic nucleus deep brain stimulation (STN-DBS) in Parkinson's disease (PD). We performed motor assessment (UPDRS), mood tests, cognitive, and quality of life evaluation (PDQ-39) on PD patients before surgery, and 12 and 24 months after, and we(More)
To describe a family with a hereditary ferritinopathy (HF) due to a mutation in the ferritin light chain gene (FTL498-499InsTC mutation). Case reports of the clinical features, MRI, (18)FDG PET, and pathological findings observed in this family with two patients described in more details. Postural tremor (phenotype-1) or cerebellar signs (phenotype-2) were(More)
OBJECTIVE To investigate the contribution of group II spinal pathways in Parkinsonian upper limb rigidity and the modulation of spinal excitability of group I and group II pathways by L-DOPA and subthalamic nucleus-high-frequency stimulation (STN-HFS). METHODS The effect of ulnar nerve electrical stimulation on Flexor Carpi Radialis Electromyogram (FCR(More)
OBJECTIVE The AMANDYSK trial was designed to assess long-term efficacy of chronic treatment with amantadine in patients with Parkinson disease (PD) and levodopa-induced dyskinesia (LID). METHODS This was a 3-month, multicenter, randomized, double-blind, placebo-controlled, parallel-group, wash-out study conducted in 57 amantadine-treated (≥200 mg/d for ≥6(More)
BACKGROUND Despite optimum medical management, many patients with Parkinson's disease are incapacitated by gait disorders including freezing of gait. We aimed to assess whether methylphenidate--through its combined action on dopamine and noradrenaline reuptake--would improve gait disorders and freezing of gate in patients with advanced Parkinson's disease(More)
BACKGROUND Patients suffering from Parkinson's disease (PD) describe painful sensations that could be related to neuropathic pain. Experimental data have indicated the involvement of basal ganglia and dopaminergic pathways in central nociceptive processing. AIM The objective of this study was to assess and compare the effect of levodopa on the objective(More)
BACKGROUND Multiple system atrophy (MSA) is an atypical parkinsonian syndrome including cerebellar impairment and poor response to levodopa. We assessed right hand motor activation in patients with MSA before and after an acute levodopa challenge in comparison with patients with PD and healthy volunteers (HVs). METHODS Eighteen patients with MSA, 8(More)
The "Ardouin Scale of Behavior in Parkinson's Disease" is a new instrument specifically designed for assessing mood and behavior with a view to quantifying changes related to Parkinson's disease, to dopaminergic medication, and to non-motor fluctuations. This study was aimed at analyzing the psychometric attributes of this scale in patients with Parkinson's(More)
OBJECTIVE To assess levodopa dose effect on pain thresholds in Parkinson's disease (PD) patients using an experimental nociceptive thermal stimulation. PATIENTS AND METHODS We evaluated pain thresholds in 20 PD patients treated by dopaminergic drugs. We assessed heat and cold pain thresholds by using 2 different methods (method of limits and method of(More)
Painful sensations are common in Parkinson's disease. In many patients, such sensations correspond to neuropathic pain and could be related to central alterations of pain processing. Subthalamic nuclei deep brain stimulation improves motor function in Parkinson's disease. Several structures of the basal ganglia are involved in nociceptive function, and deep(More)
