BACKGROUND Given that memantine is thought to decrease N-methyl-D-aspartic-acid-related (NMDA) glutamatergic hyperactivity and improve locomotion in rats, we sought to assess the drug's impact on axial symptoms in advanced Parkinson's disease (PD). METHODS We performed a 90-day, randomised, double-blind, study with two parallel arms: 20 mg/day memantine(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)
In this focus, we review, in the light of the recent literature, the modalities and indications of surgical cerebral revascularization for Moyamoya (MM) disease or syndrome. We also report our experience in the surgical management of adult MM. In symptomatic forms, with presence of severe disturbances of perfusion or cerebrovascular reactivity on multimodal(More)
After more than 50 years of treating Parkinson's disease with l-DOPA, there are still no guidelines on setting the optimal dose for a given patient. The dopamine transporter type 1, now known as solute carrier family 6 (neurotransmitter transporter), member 3 (SLC6A3) is the most powerful determinant of dopamine neurotransmission and might therefore(More)
[(123)I]-Ioflupane single photon emission computed tomography (SPECT) is widely used to evaluate the impairment of the nigrostriatal pathway in patients with parkinsonism. We describe a patient with visually undetectable specific striatal [123I]-ioflupane binding in the striatum. Of the 950 [123I]-ioflupane SPECT scans of patients acquired in our(More)
