Non-convulsive status epilepticus resistant to benzodiazepines

Area of Science:

• Neurology
• Epileptology

Background:

• Lennox-Gastaut syndrome (LGS) is a severe form of childhood epilepsy.
• Non-convulsive status epilepticus (NCSE) presents diagnostic and therapeutic challenges.

Observation:

• Intravenous benzodiazepine administration was attempted in six LGS patients with NCSE.
• Treatment efficacy and adverse events were monitored.

Findings:

• Benzodiazepines were ineffective in controlling NCSE in all six LGS patients.
• One patient exhibited a paradoxical reaction, worsening both clinical and electroencephalographic seizure activity.

Implications:

• Current benzodiazepine protocols may be insufficient for NCSE in LGS.
• Alternative or adjunctive treatments are needed for managing NCSE in this patient population.
