Myoclonic epilepsy in infancy

Dravet syndrome, previously known as severe myoclonic epilepsy of infancy (SMEI), is an autosomal dominant genetic disorder which causes a catastrophic form of epilepsy, with prolonged seizures that are often triggered by hot temperatures or fever. It is very difficult to treat with anticonvulsant medications. It often begins before 1 year of age. :: Severe myoclonic epilepsy in infancy Synonyms: Dravet syndrome Definition: The typical form of severe myoclonic epilepsy in infancy combines: normal psychomotor development prior to epilepsy, convulsive crises which are often febrile and long lasting at about six months of age, even earlier. These Myoclonic epilepsy in infancy (MEI) is characterized by brief generalized myoclonic seizures associated with generalized spike‐wave paroxysms without other seizure types occurring in the first 3 years of life in developmentally normal children. In this study we analyze the electroclinical features, treatment, and outcome of 38 patients with MEI. Diacomit is used in children with a very rare type of epilepsy called ‘severe myoclonic epilepsy in infancy’ (SMEI), also known as Dravet’s syndrome.

Voltage-gated sodium channels (Na(V)) are critical for initiation of action potentials. Heterozygous loss-of-function mutations in Na(V)1.1 channels cause severe myoclonic epilepsy in infancy (SMEI).

2012-07-20 · [Reflex myoclonic epilepsy in infancy: a new reflex epilepsy syndrome or a variant of benign myoclonic epilepsy in infancy] Caraballo R, Cassar L, Monges S, Yepez I, Galicchio S, Cersosimo R, Fejerman N. Rev Neurol, (5):429-432 MED: 12640595 Objectives: SCN1A mutations were recently reported in several patients with severe myoclonic epilepsy in infancy (SMEI). The authors analyzed SCN1A mutations in 93 patients with SMEI and made genotype-phenotype correlation to clarify the role of this gene in the etiology of SMEI. Mutations in the neuronal voltage-gated sodium channel α-subunit type I gene ( SCN1A ) were found responsible for severe myoclonic epilepsy in infancy (SMEI). The authors describe novel mutations of SCN1A in Japanese patients with SMEI. They screened 12 unrelated patients and a pair of monozygotic twins and detected 10 mutations that lead to truncation of the protein.

Mutations in SMEI include missense, nonsense, and frameshift mutations more commonly arising de novo in affected patients. This finding is difficult to reconcile with the family Using Next Generation Sequencing for the screening of patients with idiopathic epilepsy, we identified the p.Arg550Cys (c.1648C>T) heterozygous mutation on HCN4 in two brothers affected by benign myoclonic epilepsy of infancy. athy, early myoclonic epilepsy, infantile spasms/West syndrome, severe myoclonic epilepsy of infancy, myo-clonic-astaticepilepsy,generalizedepilepsywithfebrile seizures plus, malignant migrating partial seizures of infancy, hemiconvulsions-hemiplegia-epilepsy, benign myoclonic epilepsy, and benign familial/nonfamilial infantile seizures. 2021-04-09 · An electroclinical epilepsy syndrome diagnosis enables physicians to predict outcomes as well as select appropriate treatment options.

This syndrome was recognizable from the second or third seizure in the first year of life, although epileptiform EEG abnormalities were lacking until the age of 11 to over 30 months. The mainstays of medical therapy for myoclonic epilepsy are valproic acid (sodium valproate), ethosuximide, or benzodiazepines (clonazepam or clobazam). [] .
