Dravet syndrome (DS) is an intractable paediatric electroclinical syndrome beginning in the first 24 months of life, with generalized or hemi-convulsive seizures initiated by fever (often associated with vaccines) or hyperthermia, which are often prolonged. Dravet syndrome is a rare form of epilepsy that starts when an otherwise healthy child is a baby.. Dravet syndrome (previously known as “severe myoclonic epilepsy of infancy”) was first described by Dr. Charlotte Dravet in 1978. This phenotype comprised heterogeneous seizure types with nocturnal generalized tonic-clonic seizures predominating, mild to severe intellectual disability, and variable motor abnormalities. Most cases are due to severe SCN1A gene mutations. In a small amount of cases, a clinical diagnosis of Dravet Syndrome is linked to a mutation in genes other than SCN1A. Careful semiological analysis of the seizures and a prolonged video-EEG during wakefulness and sleep periods allowing interictal analysis and seizure capture may help. ABSTRACT: Dravet syndrome and Lennox-Gastaut syndrome are severe epileptic encephalopathies that manifest during early childhood. Novel mutations were described for 11 adult patients; one patient had three SCN1A mutations. As children with Dravet syndrome get older, their decline in cognitive function stabilizes. But for all, the condition is complex, symptoms can be interrelated and seizures can be highly unpredictable. Most children develop varying degrees of developmental disability. The condition causes a lot of seizures that are hard to control. We identify several key findings. Dravet syndrome begins to appear at a child’s first year of life with periodic seizures that is related with fever and on the second year of life, other types of seizures start to come out. This content is not intended to be a substitute for professional medical advice, diagnosis, or treatment. We aimed to delineate the cognitive, behavioral, and psychosocial functioning of children and adults with Dravet syndrome. Dravet syndrome is a rare, drug-resistant epilepsy that begins in the first year of life in an otherwise healthy infant. Introduction. They all had seizures not responding to epilepsy medicines. Dravet Syndrome News is strictly a news and information website about the disease. Clinical course of Dravet Syndrome – Comorbidities. They attend occupational day centres, sheltered workshops or special professional schools. The purpose of our study was to acquire information concerning the potential risks and benefits of (ox)carba(ma)zepine withdrawal in adult patients with genetically confirmed Dravet syndrome. Gait abnormalities seem to worsen during adolescence. Seizures may be difficult to treat. New webinar - 'COVID-19 & Dravet Syndrome: Latest Updates' taking place via Zoom at 8pm on Monday 11th January. Twenty-two adults with Dravet syndrome, 10 female, were included, median age 39 years (range 20-66). First, most participants had global cognitive impairment; however, in the small sample who were able to comply with further neuropsychological testing, we identified intact visual perception abilities and an ability to distinguish … Although Dravet Syndrome is recognised as a rare form of epilepsy, epilepsy is just one part of living with Dravet Syndrome - the range and severity of symptoms vary from one individual to another. In both cohorts, we collected information about genetic mutation, and semiology of seizures at onset and during disease course. Dravet Syndrome Treatments. It is lifelong. Adult patients with Dravet syndrome are usually partially dependent or live in special institutions. More than 85% of children and adults diagnosed with Dravet Syndrome have a mutation in a gene known as SCN1A. Its aim was to record side effects, changes in seizure symptoms, and overall improvements in patients’ quality of life over years of Epidiolex use. In Dravet syndrome, interictal and ictal electroencephalography (EEG) recording may remain misleading, and are not specifically altered. We analyzed the phenotype of 14 adults with severe myoclonic epilepsy of infancy. Abstract 1057 2. Behaviour and communication disorders. People with Dravet syndrome experience a wide range of severity and seizure types. Objective: To analyze the oral motor, speech, and language phenotype in 20 children and adults with Dravet syndrome (DS) associated with mutations in SCN1A . Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. An open-label, Phase 3 extension trial (NCT02224573), GWPCARE5, was conducted in a reported 681 children and young adults with Dravet or Lennox-Gastaut syndrome who took part in earlier studies. With the return to a UK-wide lockdown and roll-out of COVID-19 vaccines, we know that many families continue to have questions and concerns about the evolving situation and its implications for children and adults living with Dravet Syndrome. Methods: Fifteen verbal and 5 minimally verbal DS patients with SCN1A mutations (aged 15 months-28 years) underwent a tailored assessment battery. The children were studied over 14 weeks. "Children and Adults with Dravet syndrome face a diminished quality of life due to the debilitating number of seizures they experience, as well as the associated developmental issues. To describe the outcome of Dravet syndrome (DS) in adolescents and adults we conducted a longitudinal retrospective study of two independent cohorts of 34 adolescents (group 1) and 50 adults (group 2). Seizures typically begin during the first year of life. Dravet syndrome is among the most challenging electroclinical syndromes. 1. It is likely that Dravet syndrome is underdiagnosed in adults with treatment-resistant epilepsy. Perry MS, Knupp K, Wirrell E, et al. Challenging to diagnose and treat, patients often develop severe neurologic, intellectual, and behavioral disorders that progressively worsen. Behavioral problems: Children and adults living with Dravet syndrome may exhibit irritability, aggression, or behavior that resembles autism. The study was carried out on 120 children and young adults (aged 2-18 years) with Dravet syndrome across 23 centres across Europe and the US. If your child has this condition, they might have seizures that last for several minutes at a time. Genetic Testing. Few studies focused on the long‐term outcome of Dravet syndrome in adulthood are available in the literature, but all are concordant. Moreover, there is a great polymorphism of clinical and EEG seizure types. Presented at AES 2020 Annual Meeting; December 4–8, 2020.
