Insights
This case series details five Pakistani children diagnosed with Dravet syndrome (DS), a severe epilepsy. The study highlights varied seizure types, developmental delays, and behavioral issues, emphasizing the need for tailored management strategies for this rare genetic epilepsy.
Area of Science:
- Pediatric Neurology
- Epileptology
- Clinical Genetics
Background:
- Dravet syndrome (DS) is a severe, rare childhood epilepsy.
- It is characterized by drug-resistant seizures, developmental delays, and behavioral issues.
- SCN1A gene mutations are commonly associated with DS.
Purpose of the Study:
- To describe the clinical presentation of Dravet syndrome in five Pakistani patients.
- To highlight treatment challenges and variations in seizure control.
- To document the first cases of DS in Pakistan and inform local management.
Main Methods:
- Retrospective case series.
- Analysis of clinical data from five patients at Aga Khan University Hospital, Karachi.
- Review of seizure types, developmental and behavioral assessments, and treatment responses.
Main Results:
- Five patients presented with difficult-to-control seizures, developmental delays, and behavioral disturbances.
- Seizure types included focal clonic, myoclonic, atonic, and generalized clonic seizures.
- Fever was a seizure trigger in three cases; varied treatment responses were observed.
Conclusions:
- This study reports the first documented cases of Dravet syndrome in Pakistan.
- Unique clinical manifestations and treatment challenges were observed in this cohort.
- Findings enhance local understanding and inform management strategies for DS in Pakistan.
Abstract:
Dravet syndrome (DS) is a severe childhood epilepsy characterised by drug-resistant seizures, developmental delays, and behavioural disturbances, often linked to de novo mutations in the SCN1A gene. This retrospective case series from Aga Khan University Hospital, Karachi, describes five patients with varying ages of seizure onset and difficult-to-control seizures despite conventional antiseizure medications. Seizure types included focal clonic evolving into myoclonic, atonic, and generalised clonic seizures, with fever identified as a trigger in three cases. Developmental delays were universal, ranging from speech impairment to motor deficits. Behavioural issues such as aggression and autism spectrum traits were also observed. Treatment involved combinations of Valproic acid, Clobazam, Levetiracetam, Topiramate, and Cannabidiol, with varying responses. This study marks the first documented cases of DS in Pakistan, highlighting unique clinical manifestations and treatment challenges in this setting, thereby enhancing local understanding and management strategies for DS.

Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
