PURPOSE Childhood epilepsy with occipital paroxysms (CEOP) is characterised by ictal visual hallucinations and occipital epileptiform activity on interictal EEG. A variant has been described with nonvisual symptoms including tonic head and eye deviation, vomiting, and episodes of partial status epilepticus. We fully documented the electroclinical features(More)
Since the age of three years the patient suffered from early drug-resistant partial epilepsy with electric status during slow sleep, owing to a micropolygyric malformation of the right fronto-temporo-parietal lobes. The hemispherotomy (when five years of age) was followed by immediate and persistent disappearance of the seizures and withdrawal of the(More)
OBJECTIVE To analyse a population of children with focal cortical dysplasia operated on for drug resistant partial epilepsy, with emphasis on clinical features, seizure semiology, interictal and ictal EEG and stereo EEG findings, histological and topographical characteristics of the lesions, extension and localisation of cerebral excision, and its(More)
Severe myoclonic epilepsy of infancy (SMEI) has been long suspected to have a genetic origin. Recently mutations in the gene encoding a voltage-gated alpha-1 sodium channel subunit-SCN1A-have been identified as a common cause of SMEI. Moreover, a mutation in the gene encoding the gamma2 subunit of the GABA(A) receptor-GABRG2-has been described in a GEFS+(More)
OBJECTIVES Mutations in the EFHC1 gene have been reported in six juvenile myoclonic epilepsy (JME) families from Mexico and Belize. In this study, we screened 27 unrelated JME Italian families for mutations in the EFHC1 gene. MATERIALS AND METHODS Twenty-seven families (86 affected individuals, 52 women) with at least two affected members with JME were(More)
In congenital mirror movements (MM), it is unclear whether the "mirror" motor cortex (M1) produces output during intended unimanual movements. In two patients with MM, the cortical silent period (CSP) was abnormally short after focal transcranial magnetic stimulation (TMS) of either M1, but simultaneous bilateral TMS led to significant CSP lengthening.(More)
Merosin-deficient congenital muscular dystrophy (MD) type 1A (MDC1A) is one of the most frequent forms of CMD in Western countries. The classical form, characterized by a total lack of laminin alpha2 chain expression, usually shows severe clinical features; cases with complete laminin alpha2 deficiency and mild phenotype have also been reported, although(More)
15q.13.3 microdeletion has been described in a variety of neurodevelopmental disorders. Epilepsy appears to be a common feature and, specifically, the 15q13.3 microdeletion is found in about 1% of patients with idiopathic generalized epilepsy. Recently, absence seizures with intellectual disability (ID) have been reported in patients carrying this mutation.(More)
