Understanding Dravet Syndrome

Dravet syndrome is a rare and severe form of epilepsy that begins in infancy. It’s a lifelong condition that can have a significant impact on a child’s development and quality of life.

As someone who has worked with families affected by this rare disease, I’ve seen firsthand the challenges they face. From the initial diagnosis to managing the frequent seizures and developmental delays, it’s a journey that requires strength, patience, and a lot of support.

What is Dravet Syndrome?

Dravet syndrome, also known as severe myoclonic epilepsy of infancy (SMEI), is a rare epileptic encephalopathy that begins in the first year of life. It’s characterized by frequent, prolonged seizures that are often triggered by fever or high body temperature.

Unlike other epilepsy syndromes, Dravet syndrome is associated with significant developmental delays, language impairments, and motor difficulties. These challenges often become more apparent as the child grows older.

Symptoms of Dravet Syndrome

The hallmark symptom of Dravet syndrome is seizures, which usually start around 5-8 months of age. These initial seizures are often prolonged, lasting more than 5 minutes, and may be accompanied by fever.

As the child gets older, other seizure types emerge, including:

  • Myoclonic seizures: Brief, shock-like jerks of a muscle or group of muscles.
  • Absence seizures: Short lapses in awareness, often accompanied by staring.
  • Atonic seizures: Sudden loss of muscle tone, causing the child to collapse or fall.
  • Tonic-clonic seizures: Convulsions with muscle stiffening and rhythmic jerking.

In addition to seizures, children with Dravet syndrome often experience:

  • Developmental delays, particularly in language and motor skills.
  • Behavioral issues, such as hyperactivity, impulsivity, and autistic-like features.
  • Sleep disturbances.
  • Sensitivity to light and sound.
  • Unsteady gait and poor coordination.

Causes of Dravet Syndrome

In about 80% of cases, Dravet syndrome is caused by a mutation in the SCN1A gene. This gene provides instructions for making a protein that plays a key role in the function of brain cells.

The SCN1A mutation disrupts the normal activity of brain cells, leading to the seizures and other neurological problems associated with Dravet syndrome. In some cases, the mutation is inherited from a parent, but most often, it occurs spontaneously during early fetal development.

Prevalence of Dravet Syndrome

Dravet syndrome is a rare disorder, affecting an estimated 1 in 20,000 to 1 in 40,000 people worldwide. It occurs in all racial and ethnic groups and affects males and females equally.

While it’s considered a rare disease, increased awareness and improved diagnostic tools have led to more children being diagnosed with Dravet syndrome in recent years. This has also led to more research into potential treatments and support for affected families.

Seizure Types in Dravet Syndrome

One of the most challenging aspects of Dravet syndrome is the variety of seizure types that can occur. Each child’s experience is unique, and the frequency and severity of seizures can change over time.

Let’s take a closer look at the most common seizure types in Dravet syndrome.

Tonic-Clonic Seizures

Tonic-clonic seizures, also known as convulsive seizures, are the most recognizable type of seizure. They involve a loss of consciousness, muscle stiffening (tonic phase), and rhythmic jerking (clonic phase).

In Dravet syndrome, tonic-clonic seizures can be prolonged, lasting several minutes or more. They may require emergency intervention to stop them and prevent complications like status epilepticus, a life-threatening condition characterized by seizures that last more than 5 minutes or occur in clusters without recovery between episodes.

Myoclonic Seizures

Myoclonic seizures are brief, shock-like jerks of a muscle or group of muscles. They often occur in clusters and can involve one or both sides of the body.

In Dravet syndrome, myoclonic seizures usually begin in early childhood and may be more frequent upon awakening or when trying to fall asleep. They can be subtle and may not always be recognized as seizures by caregivers.

Absence Seizures

Absence seizures, also called petit mal seizures, involve brief lapses in awareness and responsiveness. The child may appear to be staring into space and may have subtle eye blinking or lip smacking.

In Dravet syndrome, absence seizures often have an atypical presentation and can be accompanied by myoclonic jerks or atonic features. They can be difficult to distinguish from other types of seizures and may require video-EEG monitoring for accurate diagnosis.

Atonic Seizures

Atonic seizures, also known as drop attacks, involve a sudden loss of muscle tone, causing the child to collapse or fall. They are usually brief, lasting a few seconds, but can result in injuries due to falls.

In Dravet syndrome, atonic seizures often co-occur with other seizure types, such as myoclonic or absence seizures. They can be particularly dangerous if they occur while the child is standing or walking.

Status Epilepticus

Status epilepticus is a medical emergency that requires immediate treatment. It’s defined as a seizure that lasts longer than 5 minutes or multiple seizures without regaining consciousness between episodes.

In Dravet syndrome, status epilepticus can occur with any seizure type but is most common with tonic-clonic seizures. It’s a leading cause of mortality in children with Dravet syndrome and requires a swift response from caregivers and medical professionals.

Managing the various seizure types in Dravet syndrome requires a comprehensive treatment plan that may include medications, dietary therapies, and emergency rescue medications. Caregivers must be trained in seizure first aid and have a clear plan of action for prolonged or cluster seizures.

While the seizures in Dravet syndrome can be frightening and unpredictable, with proper management and support, many children are able to achieve a good quality of life. Staying informed, advocating for your child, and connecting with other families facing similar challenges can make all the difference in your journey with Dravet syndrome.

Key Takeaway: 

Dravet syndrome is a rare and severe form of epilepsy that starts in infancy. It involves frequent, prolonged seizures often triggered by fever, developmental delays, language impairments, and motor difficulties. Proper management with medications and support can help improve the quality of life for affected children.

Diagnosing Dravet Syndrome

As a neurologist who has worked with countless families affected by Dravet syndrome, I know firsthand the challenges of getting an accurate diagnosis. It’s not always straightforward, and it can be a long, emotional journey for parents seeking answers.

Diagnosing Dravet syndrome requires a comprehensive evaluation that looks at the child’s seizure history, developmental milestones, and family background. It’s like putting together a complex puzzle, piecing together clues from various sources to form a complete picture.

Clinical Presentation

The first step in diagnosing Dravet syndrome is recognizing the characteristic pattern of seizures. In most cases, the initial seizures are prolonged febrile seizures that occur within the first year of life, often triggered by a fever or illness.

As the child grows, other seizure types emerge, including myoclonic, absence, and atonic seizures. Developmental delays also become apparent, particularly in language and motor skills. It’s a heartbreaking progression to witness, but identifying these clinical features is crucial for an accurate diagnosis.

Genetic Testing

Genetic testing has revolutionized the diagnosis of Dravet syndrome. In about 80% of cases, the condition is caused by a mutation in the SCN1A gene, which codes for a sodium channel protein essential for proper brain function.

I always recommend genetic testing for children suspected of having Dravet syndrome. A positive result can provide a definitive diagnosis and guide treatment decisions. However, it’s important to remember that a negative result doesn’t rule out the condition entirely, as some cases may have mutations in other genes or unknown causes.


While neuroimaging techniques like magnetic resonance imaging (MRI) aren’t diagnostic for Dravet syndrome, they still play an important role in the evaluation process. An MRI can help exclude other potential causes of seizures, such as brain malformations or tumors.

In most cases of Dravet syndrome, the MRI is normal, but that doesn’t mean it’s not worth doing. It’s all about gathering as much information as possible to support the diagnosis and rule out other possibilities.

Treatment Options for Dravet Syndrome

Treating Dravet syndrome is a complex and ongoing process that requires a multidisciplinary approach. As a neurologist, my goal is to work closely with families to find the best combination of therapies to control seizures and support the child’s overall development.

There’s no one-size-fits-all solution, and what works for one child may not work for another. It’s a constant balancing act, weighing the benefits and risks of various treatment options to find the optimal regimen.

Antiepileptic Medications

Antiepileptic medications are the cornerstone of treatment for Dravet syndrome. The most commonly used drugs include valproic acid, clobazam, and stiripentol, often used in combination to achieve the best seizure control.

Finding the right medication regimen can be a trial-and-error process, and it’s not uncommon for children to try several different drugs before finding the one that works best for them. It’s a frustrating process for families, but it’s important to stay patient and keep working towards the goal of seizure control.

Ketogenic Diet

The ketogenic diet, which is high in fat and low in carbohydrates, has shown promise in reducing seizure frequency for some children with Dravet syndrome. The diet works by changing the body’s primary fuel source from glucose to ketones, which may have a stabilizing effect on brain activity.

Implementing the ketogenic diet requires close supervision by a trained dietitian and regular monitoring for potential side effects. It’s not an easy lifestyle change, but for some families, the benefits in seizure control make it worth the effort.

Vagus Nerve Stimulation

Vagus nerve stimulation (VNS) is a surgical treatment option that involves implanting a small device that sends regular electrical pulses to the vagus nerve in the neck. These pulses are thought to help stabilize brain activity and reduce seizure frequency.

VNS is typically reserved for children whose seizures are not adequately controlled by medications alone. It’s not a cure, but it can be an effective adjunctive therapy when used in combination with other treatments.

Emergency Treatment

Despite our best efforts, children with Dravet syndrome are at high risk for prolonged seizures and status epilepticus, which can be life-threatening. That’s why it’s so important for families to have an emergency treatment plan in place.

This plan should include rescue medications that can be administered at home to stop a seizure quickly, as well as clear instructions on when to seek emergency medical care. It’s a scary thing to think about, but being prepared can make all the difference in a crisis situation.

Key Takeaway: 

Diagnosing Dravet syndrome involves evaluating seizure history, developmental milestones, and family background. Genetic testing can confirm the diagnosis but isn’t foolproof. MRI helps rule out other causes of seizures.

Living with Dravet Syndrome

Life with Dravet syndrome is a journey filled with challenges, but also with hope and resilience. As a parent of a child with this rare disorder, I’ve witnessed firsthand the impact it can have on every aspect of daily life. From the constant worry about seizures to the joy of celebrating small victories, living with Dravet syndrome is a rollercoaster of emotions.

One of the most significant challenges faced by Dravet syndrome people is the wide range of developmental delays that often accompany the disorder. These delays can affect language, motor skills, and social interaction, making it crucial for families to access early intervention services and ongoing support.

Developmental Delays

Children with Dravet syndrome typically experience delays in multiple areas of development, including:

  • Language: Both receptive and expressive language skills may be impaired, leading to difficulties in understanding and communicating with others.
  • Motor skills: Gross and fine motor delays can impact a child’s ability to walk, run, and perform daily tasks like writing or using utensils.
  • Social interaction: Social skills may be affected, making it challenging for children to engage in age-appropriate play and form friendships.

Early intervention is key to supporting a child’s development and maximizing their potential. This may include speech therapy, occupational therapy, and physical therapy, as well as specialized educational programs tailored to their individual needs.

Gait Abnormalities

Another common challenge in understanding Dravet Syndrome is the presence of gait abnormalities, particularly the characteristic “crouched walk” that many children develop. This abnormal walking pattern can affect balance and increase the risk of falls, making regular physical therapy and the use of assistive devices essential for maintaining mobility and preventing complications.

As a parent, I’ve learned the importance of working closely with our child’s physical therapist to develop a personalized treatment plan that addresses their specific needs. This may include exercises to strengthen key muscle groups, stretching to improve flexibility, and practicing proper walking techniques to minimize the impact of the crouched gait.

Ongoing Seizure Management

Perhaps the most significant aspect of living with Dravet syndrome is the constant need for seizure management. Despite the best efforts of medical professionals and the use of multiple anti-epileptic medications, seizures continue to be a regular occurrence for most individuals with this disorder.

As caregivers, we must remain vigilant and prepared to respond to seizures at any time. This means always having rescue medications on hand, knowing when to administer them, and being ready to seek emergency medical care if a seizure becomes prolonged or clusters occur. It’s a heavy responsibility, but one that becomes second nature over time.

In addition to medication, many families find that implementing lifestyle changes, such as following a ketogenic diet or avoiding known seizure triggers, can help reduce the frequency and severity of seizures. Working closely with a neurologist and other healthcare professionals is crucial in developing an individualized treatment plan that offers the best possible seizure control.

Support for Families

Living with Dravet syndrome brings multiple struggles, making life draining for both the patients and their families. Finding comfort through those who relate to these difficulties can make a significant difference. Groups like the Dravet Syndrome Foundation Apartments.
