Reflex Seizures Triggered by Diaper Change in Dravet Syndrome

Area of Science:

• Epilepsy research
• Genetics
• Pediatric neurology

Background:

• Dravet syndrome (DS) is a severe epilepsy syndrome with early-onset seizures.
• It is often caused by mutations in the SCN1A gene.
• Reflex seizures, triggered by specific stimuli, are known in DS.

Observation:

• A case report details reflex seizures in a girl with DS.
• Seizures were triggered by diaper changes at 9 months and 2 years old.
• This is the first reported instance of diaper change as a seizure trigger in DS.

Findings:

• The patient had a mutation in the SCN1A gene, confirming the DS diagnosis.
• Diaper changes were identified as a novel trigger for reflex seizures in this case.
• This finding expands the known range of reflex seizure triggers in DS.

Implications:

• The study broadens the understanding of reflex seizure triggers in Dravet syndrome.
• Cortical hyperexcitability, due to the genetic defect, underlies these reflex seizures.
• This case highlights the importance of identifying diverse triggers in managing DS patients.
