Abstract
In some examples, a processor is configured determine whether efficacy of therapy delivered by a medical device to the patient may have changed and generate a notification based on the determination. For example, a processor may be configured to determine whether a bioelectrical brain signal indicative of activity of a brain of a patient includes a biomarker that indicates efficacy of therapy delivered by a medical device to the patient may have changed, and generate notification based on determining the bioelectrical brain signal includes the biomarker. In some examples, the processor modifies the therapy delivered to the patient prior to generating the notification.
Claims26
A method comprising:
- controlling, with one or more processors, a medical device to deliver therapy to a patient according to a therapy program;
- receiving, with the one or more processors, information representative of a bioelectrical brain signal of the patient;
- determining, with the one or more processors and based on the information, the bioelectrical brain signal includes a biomarker, wherein the biomarker indicates a patient state in which a response of the patient to the therapy differs from a response of the patient to the therapy delivered by the medical device according to the therapy program when the patient was in a baseline state in which efficacious therapy delivery by the medical device according to the program was observed;
- and
- controlling therapy delivery by the medical device based on determining the bioelectrical brain signal includes the biomarker.
A system comprising:
- a medical device configured to deliver therapy to a patient according to a therapy program;
- and
- one or more processors configured to:
- receive information representative of a bioelectrical brain signal of the patient,
- determine the bioelectrical brain signal includes a biomarker, wherein the biomarker indicates a patient state in which a response of the patient to the therapy delivered by the medical device according to the therapy program differs from a response of the patient to the therapy when the patient was in a baseline state in which efficacious therapy delivery by the medical device according to the program was observed, and
- control the therapy delivery by the medical device based on determining the bioelectrical brain signal includes the biomarker.
A system comprising:
- a medical device configured to deliver therapy to a patient according to a therapy program;
- a memory storing a biomarker that indicates a response of the patient to the therapy delivered by the medical device according to the therapy program may have changed relative to a response of the patient to the therapy delivered by the medical device according to the therapy program when the patient was in a baseline state in which efficacious therapy delivery by the medical device according to the therapy program was observed,
- a sensing module configured to sense a bioelectrical brain signal of the patient;
- and
- one or more processors configured to:
- control the medical device to deliver the therapy to the patient according to the therapy program,
- select the biomarker stored in the memory,
- determine the bioelectrical brain signal includes the biomarker, and
- control the therapy delivery by the medical device based on determining the bioelectrical brain signal includes the biomarker.
