Myoclonic epilepsy in infancy has traditionally been divided into three types based upon the clinical features and prognosis, but they all share the common feature of myoclonic seizures with very sudden and brief muscle contractions (“jerks”) that typically involve the head and upper extremities.
av BH Skogman · 2008 · Citerat av 1 — Four cases of childhood Neuroborreliosis. Case reports are published of rare conditions associated with NB, such as myoclonus (Vukelic et al. 2000), ataxia (Ylitalo et al. The children with OND were diagnosed as having epilepsy (n=8),.
The RDP phenotype does not usually cause paroxysmal dystonia, but persistent dystonia and/or parkinsonism of subacute onset. How is the diagnosis made? Myoclonic epilepsy of infancy is diagnosed by key clinical and electroencephalography (EEG) features. This includes normal background EEG patterns.
Patients and Methods: Alpha-subunit type A of voltage-gated sodium channel (SCN1A) mutational screening was performed by denaturing high-performance liquid chromatography (DHPLC) and multiplex ligation … We compared mutation data generated by DNA array sequencing of DNA samples from patients with severe myoclonic epilepsy in infancy to the data generated by capillary sequencing. Results. Heterozygosity was detected in 44 of 48 patients (92%). BMEI - Benign Myoclonic Epilepsy in Infancy. Looking for abbreviations of BMEI?

Myoclonic epilepsy in infancy: an electroclinical study and long-term follow-up of 38 patients MEI is a well-defined epileptic syndrome of unknown etiology, but likely of a genetic cause. It is self-limited and pharmacosensitive mainly to valproic acid. MEI is a well-defined epileptic syndrome of unknown etiology, but likely of a genetic cause.
The outcome is generally benign. In rare cases, myoclonic epilepsy such as Juvenile Myoclonic Epilepsy may follow Benign Myoclonic Epilepsy in Infancy Clinic Summary: Severe myoclonic epilepsy of infancy (SMEI) is a newly recognized epileptic syndrome. It is characterized by multiple febrile seizures, often prolonged, subsequent development of uncontrollable mixed‐myoclonic seizures, and, eventually, psychomotor retardation.
Cerebral blood flow requirement for brain viability in newborn infants is lower by propofol-induced sedation in children with severe myoclonic epilepsy: a study
MEI is a well-defined epileptic syndrome of unknown etiology, but likely of a genetic cause. 38 rows Purpose: Benign myoclonic epilepsy in infancy (BMEI) is a nosologically well-defined entity, characterized by myoclonic seizures (MS) in normal children younger than 3 years and by a good long term prognosis. In some cases the seizures are reflex. Benign myoclonic epilepsy in infancy (BMEI), first described by Dravet and Bureau in 1981, is a rare epilepsy syndrome. 1 It is classified among the idiopathic generalized epilepsies and typically begins by the age of 3 years.
in patients treated with anti-epileptic agents in several indications. such as grand mal, mixed seizure patterns, myoclonic jerk patterns etc.

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.
This disease affects men and women and does not seem to be more prevalent in any particular race. While some people require treatment throughout the Myoclonic seizures involve muscle jerking and worsen with alcohol, inadequate sleep, and infections.
