Frequency analysis may have some advantages over back-averaging in the neurophysiological assessment of patients with suspected cortical myoclonus in whom myoclonic EMG bursts repeat rhythmically at high frequency. However, the clinical utility of EEG-EMG coherence and related EMG-EMG coherence is not established. Equally, there is an incomplete(More)
PURPOSE Mutations of the protocadherin19 gene (PCDH19) cause a female-related epilepsy of variable severity, with or without mental retardation and autistic features. Despite the increasing number of patients and mutations reported, the epilepsy phenotype associated with PCDH19 mutations is still unclear. We analyzed seizure semiology through ictal(More)
DCX mutations cause mental retardation in male subjects with lissencephalypachygyria and in female subjects with subcortical band heterotopia (SBH). We observed four families in which carrier women had normal brain magnetic resonance imaging (MRI) and mild mental retardation, with or without epilepsy. Affected male subjects had SBH or pachygyria-SBH. In two(More)
We describe a pedigree in which eight individuals presented with a non-progressive disorder with onset between the ages of 12 and 50 years. It was characterized by predominantly distal, semi-continuous rhythmic myoclonus (all patients), generalized tonic-clonic seizures (all patients) and complex partial seizures (three patients). Most individuals had(More)
ENM is an etiologically heterogeneous disorder clinically evident as brief (less than 500 msec) lapses of tonic muscular contraction which seems to be related to lesions or dysfunction of different anatomofunctional levels of the CNS (Fig. 13). ENM can occur in heterogeneous epileptic disorders, ranging from benign syndromic conditions (such as BECTS) to(More)
PURPOSE Carisbamate, a novel neuromodulatory agent with antiepileptic properties, was evaluated in patients with photoparoxysmal responses to intermittent photic stimulation (IPS) in this multicenter, non-randomized, single-blind, placebo-controlled, proof-of-concept study. METHODS Eighteen Caucasian patients (14 females, 4 males) with a mean age of 30(More)
PURPOSE To report on the association of childhood absence epilepsy and paroxysmal dyskinesia (PD). METHODS We describe six patients aged 6 to 27 years (mean, 14 years) who were identified in five centers participating in a European study group. Patients had been followed up clinically from the first symptoms and had been studied with video-EEG recordings(More)
We describe a pedigree in which 3 members in the same generation are affected by Rolandic epilepsy (RE), paroxysmal exercise-induced dystonia (PED), and writer's cramp (WC). Both the seizures and paroxysmal dystonia had a strong age-related expression that peaked during childhood, whereas the WC, also appearing in childhood, has been stable since diagnosis.(More)
An 8-year-old girl with Lennox-Gastaut syndrome showed a partial reduction in seizure frequency when lamotrigine (LTG), 15 mg/kg per day, was added to clobazam (CLB) and vigabatrin (VGB). An increase in LTG dosage to 20 mg/kg per day produced no further improvement and was followed by myoclonic status epilepticus. The condition developed insidiously and(More)
