Few studies focused on the long-term outcome of Dravet syndrome in adulthood are available in the literature, but all are concordant. Sleep Abnormalities in Children With Dravet Syndrome. Epileptic seizures tend to become less frequent and less severe after childhood. Epileptic seizures tend to become less frequent and less severe after childhood. Generalized convulsive seizures, mostly reported as generalized tonic-clonic seizures (GTCS), were the only seizure type observed in almost all of the patients, often with a focal onset. Five patients had a gross walking impairment and two used a wheelchair. Preventive measures have not been discussed in the literature, but one can assume that better management of acute seizure situations and SE may decrease the mortality linked to SE; we have introduced in our practice the avoidance of soft pillows in patients with DS at any age, in order to try and minimize the consequences of respiratory depression, one of the putative contributors to SUDEP. (2010) reported 30% with persisting fever sensitivity. Among the 14 patients reported by Jansen et al. 1). Delayed maturation of GABAergic signaling in the Scn1a and Scn1b mouse models of Dravet Syndrome.

Few studies focused on the long‐term outcome of Dravet syndrome in adulthood are available in the literature, but all are concordant. The range of clinical pictures widened further after the description of the SCN1A mutations that underline a majority of cases with DS. Since the myoclonic component of this type of epilepsy isn’t always present and there is some observed symptomatology variability, in 1989, Dravet syndrome became its name. Visit our Dravet Syndrome and COVID-19 Resource Hub. Outlining a core neuropsychological phenotype for Dravet syndrome. As it was discovered that not all of the original clinical signs were present in every patient, the diagnostic criteria were expanded. Repeated eye closure provoked generalized discharges and a slight loss of contact. Five patients (20.8%) died, at a mean age of 24.8 years, one by status epilepticus, three by sudden unexpected death in epilepsy (SUDEP), and one of unknown cause. The overall frequency of seizures is much lower than in the young pediatric cases. The impact of Dravet syndrome differs from patient to patient, with seizure frequency and severity, cognitive and behavioral skills, and response to treatment varying widely and evolving over time. In patients who still experience myoclonic seizures and atypical absences, obtundation status may also occur: Two patients among 31, at the ages of 43 and 22 years (Akiyama et al.,2010), and 4 in our cohort of 24 patients experienced occasional nonconvulsive SE.

There is a high likelihood of recurrent status epilepticus; seizures are medically refractory; and patients have multiple co-morbidities, including intellectual disability, behaviour and sleep problems, and crouch gait. Working off-campus? However, this very severe picture was observed in patients with often delayed diagnosis and inadequate treatment. 2020 Jun;177(12):2779-2792. doi: 10.1111/bph.15003. Epilepsy Res. Generalized convulsive seizures, mostly reported as generalized tonic–clonic seizures (GTCS), were the only seizure type observed in almost all of the patients [Dravet et al., 2009: 24 of 24 (two of whom had been in remission for at least a year); Jansen et al., 2006: 14 of 14; Akiyama et al., 2010: 26 of 31]. The major feature of DS remains the high risk of lethality: Although adequate medical intervention and management may reduce the risk of death due to seizures and SE, the high incidence of SUDEP, especially in older children and young adults, singles out DS among other epileptic encephalopathies. Researchers discovered the genetic etiology of this epilepsy in 2001, and various studies since then have helped researchers gain a better knowledge of the condition. The full text of this article hosted at iucr.org is unavailable due to technical difficulties. Dravet syndrome is a rare, severe, and lifelong form of epilepsy (seizure disorder) that causes frequent, prolonged seizures.The seizures are often triggered by health problems such as high body temperature (hyperthermia).

Electroencephalography (EEG) also changes with age but is still multiple and heterogenous, interictally and ictally. While Dravet syndrome patients don’t appear to be at increased risk of severe COVID-19 complications, more study is needed about potentially adverse effects of prolonged social distancing and other preventative measures, a Dravet Syndrome UK (DSUK) survey indicates.. Doose H, Lunau H, Castiglione E, Waltz S. Neuropediatrics. 2020 Mar 1;143(3):e19. All adult patients had significant impairment. (2001) reported 12 deaths among 84 patients, at a mean age of 65 months, including 7 deaths in 38 with typical SMEI versus 5 deaths in 45 with “borderline” SMEI. 2020 Jul 21;8:654. doi: 10.3389/fcell.2020.00654. Recently diagnosed cases seem to enjoy a slightly less severe evolution, perhaps as a consequence of more efficient treatment options and better global care. The evolution of DS from early childhood into adulthood follows a fairly predictable pattern, and the range of situations found in adults is limited. Dravet syndrome is the most severe of a group of conditions known as SCN1A … SCN1A‐related phenotypes: Epilepsy and beyond. 2014 Apr;55(4):528-38. doi: 10.1111/epi.12532. Epidemiologic aspects: Lost in transition. Our review is based on the study of a cohort of 24 patients followed beyond the age of 20 at our center (Dravet et al., 2009): 14 male and 10 female patients, aged 20–50 at last evaluation, first referred between 1970 and 1992. Most respondents had stable epilepsy during lockdown, and prior adoption of protective measures against general infection might have contributed to avoiding COVID-19 infections. Cerebellar features, including ataxia, dysarthria, intention tremor, and eye movement disorder, become more prominent. Other seizures like myoclonic seizures, atypical absences, and complex partial seizures (CPS) are less common in adulthood: Among our 24 patients, only 6 had atypical absences, and one myoclonic and one complex focal seizures. Cerebellar features including ataxia, dysarthria, intention tremor, and eye movement disorder are most prominent. Brain.

Dravet syndrome: a sodium channel interneuronopathy. None had been seizure‐free in the Australian patients’ group (Jansen et al., 2006). Among the 31 adult patients reported by Akiyama et al. Generalized convulsive seizures, mostly reported as generalized tonic–clonic seizures (GTCS), were the only seizure type observed in almost all of the patients, often with a focal onset. In DS, the long‐term perspective, which is the subject of this review, is dominated by a high mortality rate, persistence of a fairly typical epileptic encephalopathy, and by an unfavorable cognitive and a poor social outcome. Dravet syndrome is a rare, but highly refractory epilepsy syndrome. Generalized changes were infrequent. Genetic background modulates impaired excitability of inhibitory neurons in a mouse model of Dravet syndrome. Genetic factors may play a major part, and the severity of epilepsy, including the number of episodes of SE and the frequency of major seizures, are probably significant determinants. Dravet syndrome is a devastating infantile-onset epilepsy syndrome with cognitive deficits and autistic traits caused by genetic alterations in SCN1A gene encoding the α-subunit of the voltage-gated sodium channel Nav1.1.
