OBJECTIVES Parkinson's disease (PD) is characterized by the dopaminergic neuronal death in substantia nigra, and genetic factors appear to be involved in the pathophysiology of this disease. Brain-derived neurotrophic factor (BDNF) is widely expressed in the central nervous system and is necessary for the survival of dopaminergic neurons in substantia(More)
INTRODUCTION The corpus callosum is the major neopallial connection between the two cerebral hemispheres. The corpus callosum agenesis (CCA) is found in 14% of CNS malformations. The diagnosis is based on neuroimaging procedures (ultrasonography, CT, MRI). The CCA is usually associated with facial dysmorphia, developmental delay and epileptic seizures. Two(More)
INTRODUCTION Zolpidem is a non-benzodiazepine drug used for the therapy of insomnia, which has selectivity for stimulating the effect of GABA-A receptors. Recently, a paradoxical arousing effect of zolpidem in patients with severe brain damage has been repeatedly reported. METHODS A placebo-controlled magnetic resonance study was conducted to evaluate its(More)
BACKGROUND Focal thalamic lesions have been associated with a variety of involuntary movements such as tremor, dystonia, and chorea-ballism. METHODS We describe a patient with severe hyperkinesias of the right arm secondary to a thalamic infarction in the left postero-ventral region of the thalamus. RESULTS The dystonia and tremor of the right upper(More)
BACKGROUND We report a 15 year-old girl with sickle cell disease, who developed important cognitive impairment due to multiple strokes, and who had been diagnosed with PVS. Nonetheless, when she was later admitted to our Institute, according to the presence of inconsistent but clearly demonstrable behavioral evidence of consciousness awareness, we changed(More)
OBJECTIVE The initial phases and transitional periods of sleep facilitate electroclinical manifestations of juvenile myoclonic epilepsy (JME). The period at the time of waking is identified in the different phases of sleep by cyclic electrophysiological oscillations, which in turn are synchronous with the spike-and-wave or multiple spike-and-wave activity(More)
