Dravet syndrome (DS) is a severe, rare, and complex developmental and epileptic encephalopathy affecting 1 in 16 000 live births and characterized by a drug‐resistant epilepsy, cognitive, psychomotor, and language impairment, and behavioral disorders. Evidence suggests that optimal treatment of seizures in DS may improve outcomes, even though neurodevelopmental impairments are the likely result of both the underlying genetic variant and the epilepsy. We present an updated guideline for DS diagnosis and treatment, taking into consideration care of the adult patient and nonpharmaceutical therapeutic options for this disease. This up‐to‐date guideline, which is based on an extensive review of the literature and culminates with a new treatment algorithm for DS, is a European consensus developed through a survey involving 29 European clinical experts in DS. This guideline will serve professionals in their clinical practice and, as a consequence, will benefit DS patients and their families.

Objective: Dravet syndrome (DS) is a severe developmental and epileptic encephalopathy caused by SCN1A haploinsufficiency in the majority of cases. Caregivers of adults with DS often complain about the loss of previously acquired skills. We set out to explore these perceptions and determine whether abnormalities reported were detectable in validated tests. We also investigated possible correlations between symptoms, age, and exposure to sodium channel blockers (SCBs). Methods: This cross‐sectional, multicenter study used the Vineland Adaptive Behavior Scales, 3rd edition (raw scores) for behavior analyses and Moss–Psychiatric Assessment Schedules checklist to screen for psychiatric symptoms. The Social Communication Questionnaire screened for social communication deficits. Parkinsonian features were evaluated with the modified Unified Parkinson's Disease Rating Scale. For gait evaluation, we validated the use of home videos, using instrumental gait analysis in a subgroup of patients, and then used the home videos for the remainder. Results: A total of 92 patients were enrolled (age range = 18–51 years, mean = 27.93 ± 8.59 years). Sixty percent of caregivers observed a decline in previously acquired skills, including intelligence, speech, interaction with others, ability to climb stairs and walk without support, and hand coordination. Adaptive skills, parkinsonian symptoms, and gait were worse in older patients and those exposed to SCBs for longer periods of time. Fourteen percent of patients screened positive for affective disorders, 11.6% for dementia, and 10.5% for a psychotic disorder. Fifty‐three percent screened positive for social communication deficits. Significance: This is the largest group of adults with DS to be systematically evaluated. They had severe nonseizure symptoms. Older age and longer use of SCBs were associated with worse adaptive skills, gait, and parkinsonism. Some older adults screened positive for depression and dementia. Caregivers identified functional decline in activities of daily living (ADLs). Taken together, the risk of dementia, parkinsonian gait, and decline in ability to perform previously mastered ADLs support that some adults with DS may be developing a neurodegenerative disorder.

Dravet syndrome (DS) is a rare and severe form of epilepsy that begins in infancy, which is primarily caused by pathogenic variants in the SCN1A gene. DS is characterized by prolonged and frequent drug-resistant seizures, as well as developmental delays and behavioral problems. The identification of these comorbidities is based on clinical interview and relies on healthcare professionals (HCPs) experience. We assembled a group of expert HCPs and caregivers to create a screening checklist for assessing DS-Associated Neuropsychiatric Comorbidities (DANC). The checklist includes questions related to cognitive and psychiatric domains, motor skills, and the impact of DS on families' daily lives. We administered the checklist to 24 caregivers of DS patients from Belgium, France, and Spain. After piloting, we obtained feedback from expert HCPs and caregivers to refine the checklist. DS patients showed a wide array of neuropsychiatric symptoms related to DS. The most common cognitive domains reported were attention difficulties and multitasking problems (18/24 caregivers), and impulsivity (17/24), while the most common psychiatric symptoms were temper tantrums (14/24), mood swings (13/24) and autism spectrum disorder (12/24). Balance and coordination problem have been reported in almost all patients with a statement of only 4/23 with complete mobility. Most patients were dependent on others for self-care and eating, and presented sleeping disturbances. Caregivers reported high levels of stress in the family unit, both between siblings and parents. Results show that the main concerns of parents were the behavior and the cognition of the person with DS. The quantitative feedback results showed good-to-very good scores on usefulness, ease of completion, clarity and comprehensiveness of the checklist. This pilot study suggests that the DANCE checklist could be a useful screening tool in daily practice for neuropsychiatric comorbidities facilitating their diagnosis and treatment, and empowering both caregivers and patients.

Dravet syndrome (DS) is a genetic rare disease, which is usually caused by a mutation in the SCN1A gene. DS is characterised by a drug-resistant epilepsy and by cognitive and behavioural disturbances. Thus, DS patients require both pharmacological and non-pharmacological treatments. However, there is a paucity of studies on non-pharmacological therapies and their potential benefits. The main aim of this study was to describe the non-pharmacological therapy modalities received by DS patients and their socio-economic impact on the family. Thus, we designed an online survey addressed to caregivers of DS patients. Our results indicated that up to 91.9% of the surveyed patients required non-pharmacological therapies, which were mainly directed to treat cognitive, sensory and motor impairments. In many cases, the economic costs of these therapies were borne entirely by the families. Nevertheless, patients required a deployment of resources not only at a health care level, but also at an educational level.

Dravet syndrome (DS) is a rare developmental and epileptic encephalopathy that presents with frequent and prolonged seizures resistant to treatment as well as cognitive problems such as behavioral and developmental delays. However, there is a lack of scientific literature on the impact of this condition on caregivers and the family unit. To find out the social and emotional impact of DS on the family unit, to provide a comprehensive understanding of the disease's effects on both the family and caregivers. A tailored online survey was administered to Spanish DS families, collecting data on the employment, financial, emotional, and social status of patients and caregivers. A total of 112 Spanish caregivers participated in the study. The mean age of the 112 parents was 46.61 years, and 77.68 % of them were mothers. The majority of caregivers had to quit their jobs or reduce their working hours to take care of their child with DS, being the most of them mothers. Most of the caregivers felt that they were not well-informed by healthcare professionals (HCPs) and the Spanish National Health System (NHS). Despite access to resources, families often face financial strain and challenges in obtaining sufficient support, highlighting the need for enhanced social, economic, and psychological backing. In addition, both sentimental and social relationships were negatively impacted in the vast majority of respondents. The study advocates for policy reforms, integrated social services, community programs, and multidisciplinary efforts to improve the quality of life and social integration for those affected by DS.

Objectives: Dravet syndrome (DS) is a rare form of refractory epilepsy that begins in the first year of life. Approximately 85% of patients have a mutation in the SCN1A gene, which encodes a voltage‐gated sodium channel. The main objective of the present work was to assess the degree of knowledge of DS among Spanish primary care (PC) professionals, the communication flow between them and the pediatric neurologists (PNs), and the services available and resources offered to patients in Spain when searching for a diagnosis and adequate treatment.Methods: Two anonymized online surveys on DS diagnosis and patient management in PC were conducted with Spanish PC pediatricians (PCPs) and caregivers of DS patients in Spain.Results: Most PCPs are aware of genetic epilepsy but lack full knowledge of DS and patient advocacy groups (PAGs). Access to epilepsy treatments varies among regions, with many referrals to hospitals and pediatric neurologists. Diagnosis is often delayed, with misdiagnoses and frequent emergency room (ER) visits. Treatment involves multiple drugs, and sodium channel blockers are used, which are contraindicated in DS treatment. Improved training, resources, and communication are needed for early diagnosis.Significance: To improve the care and treatment of DS patients in Spain, early diagnosis is required and, possibly, specific efforts aimed at identifying patients in adulthood, generating socio‐sanitary structures that integrate social and health services to provide comprehensive care, taking into account the different features and comorbidities of the disease.Plain Language Summary: Dravet syndrome (DS) is a form of genetic epilepsy that starts within the first year of life. We present a study showing that, while family doctors are aware of genetic epilepsies, many don't have a complete understanding of DS. Unfortunately, getting the right diagnosis can take a long time, leading to unnecessary visits to the emergency room. Patients often need several medications, and sometimes they're given drugs that aren't recommended for DS. The takeaway is that training for doctors, more resources, and improved communication could help creating better healthcare systems and therefore give easier access to the right therapies.
