The RNS System detects seizures and delivers targeted stimulation to prevent seizures.
RNS involves:
- Implanted NeuroPace device
- Cortical electrodes
- Detects and responds
- Closed-loop system
- Epileptogenic zone
- Most active area
- Direct stimulation
- Propagation zone
- Network effects
- Surrounding inhibition
- Centromedian nucleus
- Generalization prevention
- Thalamic modulation
- EEG patterns
- Specific frequencies
- Automated detection
- Biphasic pulses
- Responsive to activity
- Immediate effect
- Prevents propagation
- May reduce excitability
- Long-term changes
- Medically intractable
- One or two foci
- Not candidates for surgery
- Hippocampal focus
- Common target
- Good response
- Extra-temporal
- Variable
- Careful selection
- 50% reduction common
- 30-70% responder rate
- Improves over time
- No cognitive decline
- May improve
- Monitored
- RNS System (2022)
- Responsive neurostimulation (2021)
