PURPOSE The role of the familial background in severe myoclonic epilepsy of infancy (SMEI) has been traditionally emphasized in literature, with 25-70% of the patients having a family history of febrile seizures (FS) or epilepsy. We explored the genetic background of SMEI patients carrying SCN1A mutations to further shed light on the genetics of this(More)
The clinical understanding of the CDKL5 disorder remains limited, with most information being derived from small patient groups seen at individual centres. This study uses a large international data collection to describe the clinical profile of the CDKL5 disorder and compare with Rett syndrome (RTT). Information on individuals with cyclin-dependent(More)
The authors describe 7 new cases of Angelman syndrome (AS: 3 males and 4 females) diagnosed on the basis of clinical features (dysmorphic facial features, severe mental retardation with absent speech, peculiar jerky movements, ataxic gait and paroxysms of inappropriate laughter) and neurophysiological findings. Failure to detect deletion of the long arm of(More)
The KCNT1 gene encodes for subunits contributing to the Na(+)-activated K(+) current (KNa), expressed in many cell types. Mutations in KCNT1 have been found in patients affected with a wide spectrum of early-onset epilepsies, including Malignant Migrating Partial Seizures in Infancy (MMPSI), a severe early-onset epileptic encephalopathy characterized by(More)
PURPOSE To evaluate the potential efficacy of levetiracetam as an antiabsence agent in children and adolescents with newly diagnosed childhood or juvenile absence epilepsy. METHODS Patients were randomized in a 2:1 ratio to receive de novo monotherapy with levetiracetam (up to 30 mg/kg/day) or placebo for 2 weeks under double-blind conditions. Responder(More)
PURPOSE A locus for benign familial convulsions (BFICs) has been recently mapped on chromosome 19q12-13.1 by studying five families of Italian descent. The main goal of this study was to investigate the role of this locus in a set of seven newly identified families with at least three affected cases. METHODS Five polymorphic microsatellite markers(More)
The Italian League Against Epilepsy Commission Guidelines Subcommittee on Status Epilepticus (SE) has published an article on the management of SE in adults, and now presents a report on the management of convulsive status epilepticus (CSE) in children, excluding the neonatal period. Children's greater susceptibility than adults to epileptic seizures(More)
PURPOSE Benign familial infantile seizures (BFIS) is a genetically heterogeneous condition characterized by partial seizures, onset age from 3 to 9 months, and favorable outcome. BFIS loci were identified on chromosomes 19q12-13.1 and 16p12-q12, allelic to infantile convulsions and choreathetosis. The identification of SCN2A mutations in families with only(More)
A cohort of 582 Italian primary school teachers underwent a questionnaire survey to test their knowledge and attitudes toward epilepsy and verify whether an intensive and focused educational program could result in improvement of knowledge and attitudes. The program consisted of a presentation of the clinical manifestations of epilepsy and the distribution(More)
Haemophagocytic lymphohistiocytosis (HLH) is characterized anatomically by an infiltration of multiple tissues with lymphocytes and haemophagocytic histiocytes. First symptoms are usually hepatosplenomegaly, pancytopenia, and intractable fever. Up to 73% of those with HLH develop CNS involvement during the disease course. The peculiarity of the two patients(More)
