Refractory (or drug-resistant) epilepsy refers to seizures that do not respond to at least two appropriate anti-epileptic drugs.

Q2. What are the main treatment options?
Beyond AEDs, treatments include surgical resection, neuromodulation devices (VNS, RNS, DBS), ketogenic diet, and investigational gene therapies.

Q3. Which region dominates the market?
North America currently leads, but Asia-Pacific is expected to grow fastest due to increasing epilepsy prevalence and improved healthcare infrastructure.

Q4. What role does technology play in this market?
Neuromodulation and minimally invasive surgical tools are revolutionizing treatment pathways for drug-resistant patients.

Q5. Who are the key market players?
Major players include UCB Pharma, Medtronic, NeuroPace, Boston Scientific, Eisai, and Novartis.
