Neuromodulation is a key therapeutic tool for clinicians managing patients with drug-resistant epilepsy. Multiple devices are available long-term follow-up and real-world experience. The aim of this review to give practical summary neuromodulation techniques guide the selection modalities, focusing on patient devices, common approaches initiation programming, outpatient management issues.

In patients with drug-resistant epilepsy, electrical stimulation of the brain in response to epileptiform activity can make seizures less frequent and debilitating. This therapy, known as closed-loop responsive neurostimulation (RNS), aims directly halt seizure via targeted a burgeoning seizure. Rather than immediately stopping they start, many RNS implants produce slower, long-lasting changes dynamics that better predict clinical outcomes. Here we hypothesize during states drives long-term restore healthy networks. To test this, quantified episodes low- high-risk states-that is, periods lower or higher risk generating activity-in cohort 40 treated RNS. More tonic low-risk out rhythmic predicted reduction. Additionally, events were more likely be phase-locked prolonged abnormal for intermediate poor responders when compared super-responders, consistent hypothesis improved outcomes are driven by states. These results support might underlie mechanisms RNS, suggesting relationship between temporal patterns neuromodulation plasticity facilitates

Deep brain stimulation (DBS) is a promising neuromodulation therapy, but the neurophysiological mechanisms of DBS remain unclear. In awake mice, we performed high-speed membrane voltage fluorescence imaging individual hippocampal CA1 neurons during delivered at 40 Hz or 140 Hz, free electrical interference. powerfully depolarized somatic potentials without suppressing spike rate, especially Hz. Further, paced and timing frequency reduced timed spiking output in response to network theta-rhythmic (3-12 Hz) activity patterns. To determine whether directly impacts cellular processing inputs, optogenetically evoked depolarization soma. We found that DBS-evoked was correlated with DBS-mediated suppression neuronal responses optogenetic inputs. These results demonstrate produces powerful interferes ability respond creating an informational lesion.
