Abstract
An implantable neurostimulator adapted to provide adaptive electrical brain stimulation includes a detection subsystem for isolating an electrographic signal characteristic and a stimulation system for applying an adaptive stimulation signal based at least in part upon the electrographic signal characteristic and correlated with the electrographic signal. Undesired learning of and acclimation to stimulation characteristics are avoided and stimulation efficacy is improved by adapting or otherwise varying the adaptive stimulation signal in relation to the electrographic signal.
Claims23
A method for treating a neurological disorder in a human patient with a neurostimulator by applying electrical stimulation that is adaptive to a characteristic of an electrographic signal in the patient's brain, the method comprising the steps of:
- measuring the characteristic of the electrographic signal;
- generating a treatment waveform from the characteristic;
- and
- applying a stimulation signal representative of the treatment waveform.
A method for treating a neurological disorder in a human patient with a neurostimulator by applying an adaptive electrical stimulation signal, the method comprising the steps of:
- detecting a neurological event in a first electrographic signal;
- measuring a characteristic of a second electrographic signal;
- generating a treatment waveform from the characteristic;
- and
- applying a stimulation signal representative of the treatment waveform to the patient's brain.
An implantable neurostimulator for the treatment of a neurological disorder, comprising:
- a detection subsystem adapted to detect a neurological event and to measure a characteristic of an electrographic signal;
- a stimulation subsystem adapted to apply a stimulation signal to the patient's brain, wherein the stimulation signal is representative of a treatment waveform generated at least in part from the characteristic.
