Optimization of Deep Brain Stimulation Parameters in Patients With Medically Refractory Epilepsy
October 6, 2023 updated by: University of Minnesota
Deep brain stimulation (DBS) is used to treat epilepsy in cases where patients are medically refractory and are not candidates for surgical resection.
This therapy has been shown to be effective in seizure reduction, yet very few patients achieve the ultimate goal of seizure freedom.
Implantable neural stimulators (INSs) have many parameters that may be adjusted, and could be tuned to achieve very patient specific therapies.
This study will develop a platform for stimulation setting optimization based on power spectral density (PSD) measures.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Difference in broadband power with different settings
Time Frame: One year from baseline
|
Different settings include different combinations of stimulation amplitude, frequency and pulse width.
The full spectrum PSD data from all of the in-clinic recordings at all of the unique settings will be combined to look at the resulting difference in broadband power.
|
One year from baseline
|
Difference in frequency band-specific low-frequency power (LFP) with different settings
Time Frame: One year from baseline
|
Different settings include different combinations of stimulation amplitude, frequency and pulse width.
The full spectrum PSD data from all of the in-clinic recordings at all of the unique settings will be combined to look at the resulting difference in frequency band-specific LFP.
