What Is the Treatment of Epileptic Encephalopathy with Continuous Spike-and-Wave During Sleep?
This first-line protocol addresses epileptic encephalopathy with continuous spike-and-wave during sleep (CSWS). Treatment goals target both clinical improvement and a measurable reduction in the abnormal sleep EEG pattern, as defined by the sleep spike-wave index (SWI).
First-Line Treatment Approach
The protocol involves an oral benzodiazepine administered before sleep. This is one of several recognised treatment strategies for CSWS — the complete regimen, including specific agent selection and the full clinical algorithm, is available in the structured protocol.
Treatment Goals
- Clinical response: improvement in neurocognitive function, seizure control, or EEG findings.
- SWI response: at least 50% reduction in the sleep spike-wave index (SWI), comparing post- and pre-treatment EEGs.

- There are currently four primary treatment strategies: high-dose oral benzodiazepines given before sleep, steroids, other anti-seizure medications (ASMs), or epilepsy surgery.
- CSWS treatments were categorized as: (a) benzodiazepines (clobazam and oral diazepam), (b) steroids; (c) ASMs; and (d) other (including surgery, ketogenic diet, IVIG).
- While the majority of patients first receive a benzodiazepine, a sizeable minority receive one of several ASMs and very few first receive steroids.
- The clinical response was defined as clinical improvement in neurocognitive function, seizures, or the EEG after therapy as judged and documented in the medical record by the treating neurologist.
- The SWI response was defined by a 50% reduction in the sleep SWI when comparing the post- and pre-treatment EEGs.
