Devices & Neuromodulation: What Families Usually Want to Know

  • When devices are considered (usually after medication trials)
  • What VNS / RNS / DBS are designed to do
  • What outcomes to expect (reduction vs β€œcure”)
  • Side effects and daily-life considerations (sleep, voice, sensations)

Common Epilepsy Device Terms in Plain English

  • VNS: a nerve stimulator (vagus nerve) that can reduce seizure frequency over time
  • RNS: detects seizure-like activity and responds with stimulation in the brain
  • DBS: steady stimulation to specific brain circuits
  • Programming: adjusting settings over multiple visits (normal and expected)
  • Responder: someone whose seizures reduce meaningfully (often measured over months)

Devices & Neuromodulation FAQ

Are devices only for adults?

Some are used more often in adults, but pediatric use depends on the device, the case, and specialist guidance.

How quickly do devices work?

Often gradually. Improvement can build over months as settings are optimized.

Do devices replace medication?

Sometimes medication can be reduced, but many people still use meds alongside a device.

Can someone get MRI scans with a device?

Sometimes yes, with device-specific rules. Always check the exact device guidelines first.
