The contribution of dopaminergic systems to cognitive defects in Parkinson's disease and the cognitive effects of levodopa remain controversial. The levodopa plasma levels and the neuropsychological performance of 10 parkinsonian patients with a stable motor response to the drug and 10 matched parkinsonian patients with a 'wearing-off' phenomenon were(More)
We report the case of a 69-year-old man with severe Tourette's syndrome (TS) who underwent a bilateral prefrontal leucotomy at the age of 29 years to alleviate coprolalia, copropraxia, and obsessive-compulsive disorder. No improvement was observed during the 5 years after the leucotomy. Tics and associated behavioral abnormalities disappeared thereafter, to(More)
INTRODUCTION Impulse control disorders (ICD) including hypersexuality, compulsive gambling, buying, eating, shopping and dopaminergic medication use, have been reported to occur frequently in Parkinson's disease (PD). Punding (complex, repetitive, excessive, non-goal oriented behaviours) have also been described. As patients may not report such behaviours(More)
Streptococcus salivarius is a usual commensal of skin, gastrointestinal tract, genitourinary tract, oral cavity and paranasal sinuses. Although it is usually considered to have low virulence, S. salivarius may cause life-threatening infections, particularly endocarditis. On the other hand, bacterial meningitis after spinal anesthesia is very rare, there(More)
Some of the selective serotonin reuptake inhibitors (SSRI)-induced motor side effects are mediated by stimulating 5-HT2 receptors in the basal ganglia, probably because serotonin inhibits the subsequent neuronal dopamine release. We hypothesized that nefazodone, a serotonin 2 antagonist/reuptake inhibitor (SARI) that selectively blocks 5-HT2 receptors,(More)
In cirrhotic patients, even in the non-encephalopathic state, MRI may show an increased signal in globus pallidus in T1-weighted sequences, the clinical significance of which is still poorly characterized. A dysfunction of the motor circuit of the basal ganglia might be predicted if the increased MRI signal expressed alterations in the globus pallidus(More)
