What is Dravet Syndrome?
Dravet Syndrome is a developmental and epileptic encephalopathy that typically begins during the first year of life in an otherwise normally developing infant. Seizures are often prolonged, may be triggered by fever or changes in body temperature, and can become difficult to control. As the condition progresses, other seizure types, developmental delays, movement and coordination difficulties, behavioural concerns, and learning problems may develop.
What is the Importance of Timely Treatment?
Timely diagnosis and treatment help control seizures, reduce prolonged seizure episodes and seizure-related injuries, monitor developmental changes, and provide appropriate supportive therapies. Early specialist management is particularly important because some commonly used antiseizure medicines can worsen seizures in people with Dravet Syndrome.
What are the Common Symptoms of Dravet Syndrome?
- Prolonged Seizures: Seizures may last several minutes or longer and can require urgent medical management.
- Fever-Triggered Seizures: Seizures may be triggered by fever, illness, overheating, or sudden temperature changes.
- Multiple Seizure Types: Children may develop myoclonic, absence, focal, or other seizure types as the condition progresses.
- Developmental Difficulties: Development may slow, or developmental delays may become noticeable during early childhood.
- Movement and Coordination Problems: Some individuals develop balance, walking, coordination, or motor difficulties.
- Behavioural and Learning Difficulties: Attention, communication, learning, and behavioural challenges may occur as the condition progresses.
Causes and Risk Factors of Dravet Syndrome
Causes
- SCN1A Gene Variant: Most cases involve a pathogenic variant in the SCN1A gene, which plays an important role in neuronal sodium-channel function.
- Altered Neuronal Function: Changes in sodium-channel activity can disrupt the balance of electrical activity in the brain and increase seizure susceptibility.
- De Novo Genetic Changes: In most affected individuals, the SCN1A variant occurs spontaneously and is not inherited from either parent.
- Other Genetic Causes: A small proportion of patients may have Dravet-like epilepsy associated with other genetic abnormalities.
- Unknown Cause: In some clinically suspected cases, clinicians may not initially identify a specific genetic cause.
Risk Factors
- Early-Onset Seizures: Seizures beginning during infancy, particularly prolonged or hemiclonic seizures, are an important clinical feature.
- Fever-Associated Seizures: Seizures frequently associated with fever or temperature changes may raise suspicion.
- Family History: A family history is uncommon because most cases result from new genetic changes, although inherited SCN1A variants can occasionally occur.
- Seizure Characteristics: Prolonged, recurrent, or multiple seizure types during infancy may be associated with the condition.
Latest Research and Technologies in the Treatment of Dravet Syndrome in India
- Recent advances in Dravet Syndrome care include genetic testing, prolonged video-EEG monitoring, advanced brain imaging, precision seizure management, and newer antiseizure therapies. Research is also exploring gene-targeted treatments, antisense oligonucleotides, gene therapy approaches, and other therapies designed to address the underlying SCN1A-related neuronal dysfunction.
Treatment options for Dravet Syndrome
Treatment is individualised according to seizure type, age, genetic findings, treatment response, developmental status, and overall health. Options may include:
Antiseizure Medicines: Specialist-selected medicines are used to reduce seizure frequency and severity.
Ketogenic Diet Therapy: A medically supervised ketogenic diet may help reduce seizures in selected drug-resistant cases.
Vagus Nerve Stimulation : VNS may be considered for some patients whose seizures remain difficult to control.

Supportive Management: Developmental, behavioural, educational, nutritional, and functional therapies form an important part of long-term care.
- Clinical assessment:
- Seizure History: Detailed evaluation of seizure onset, duration, triggers, frequency, and different seizure types.
- Neurological Examination: Assessment of muscle tone, strength, reflexes, coordination, and neurological function.
- Developmental Assessment: Evaluation of cognitive, language, motor, and developmental progress.
- Behavioral Assessment: Assessment of attention, communication, behaviour, and emotional functioning.
- Medication Review: Evaluation of previous antiseizure medicines, response, and possible seizure aggravation.
- Functional Assessment: Assessment of mobility, daily activities, communication, and independence.
- Imaging Tests:
- Video EEG: Long-term EEG with video recording helps identify and classify different seizure types.
- Sleep EEG: Sleep recordings may reveal epileptiform abnormalities that are less apparent during wakefulness.
- Brain MRI: MRI can help identify structural abnormalities and exclude other causes of epilepsy.
- PET Scan: PET may be used in selected complex cases to assess brain metabolism.
- SPECT Scan: Consider SPECT during specialised epilepsy evaluation in selected patients.
- Genetic Testing: Molecular genetic testing, particularly evaluation of the SCN1A gene, can support diagnosis and guide management.
MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive rehabilitation services designed to support Dravet Syndrome patients in India. These services include:
- Depending on individual needs, it may include physiotherapy, occupational therapy, speech and language therapy, developmental therapy, behavioural support, nutritional guidance, and educational assistance.
- Medicines are central to Dravet Syndrome management and should be selected by an experienced epilepsy specialist. Treatment may include valproate, clobazam, stiripentol, fenfluramine, cannabidiol, and other appropriate antiseizure medicines. Some sodium-channel-blocking medicines may worsen seizures in Dravet Syndrome and are generally avoided unless specifically indicated by a specialist.
