Dravetsyndrome is a rare disorder characterized byseizuresand developmental problems.
The seizures begin before age 1 year.
The cognitive, behavioral, and physical problems begin around age 2 or 3 years.

Unfortunately, you might’t outgrow Dravet syndrome.
It’s a lifelong condition due to a genetic defect in the SCN1A gene.
The life expectancy of a child with Dravet syndrome is not the average lifespan.
However, most individuals with Dravet syndrome do reach adulthood.
Symptoms can be managed with various forms of therapy.
This article explains the symptoms and causes of Dravet syndrome.
It also discusses how the condition is diagnosed and treated.
Dravet Syndrome Symptoms
Seizures are the earliest symptom of Dravet syndrome.
Developmental problems, as well as seizures, generally worsen as a child gets older.
Most people with Dravet syndrome (80% or more) live into adulthood.
Around 92% of them will still experience seizures often.
Still, the life expectancy is reduced, and adulthood is short-lived.
What Triggers Dravet Syndrome?
Sodium channels regulate brain and nerve function.
These genetic mutations appear to be new in about 90 percent of children.
They are not inherited from a parent.
A number of other genes have also been associated with Dravet syndrome but may produce slightly different symptoms.
Diagnosing Dravet Syndrome
Dravet syndrome is diagnosed based on a physicians clinical evaluation.
Diagnostic studies can support the diagnosis, but they do not confirm or exclude it.
Dravet syndrome is a lifelong condition, so it can’t be cured.
However, the symptoms can be treated.
The seizures are accompanied by developmental delays, greatly impacting quality of life.
Many of the symptoms of Dravet syndrome can partially improve with proper treatment.
Treatment strategies may need to change as your child grows physically and as the condition changes with age.
Talk to a healthcare provider or pediatrician immediately if your child is showing signs of seizures.
Healthcare providers can run tests to find the cause of the seizure and devise an appropriate treatment plan.
Ask about support groups and patient advocacy groups.
