Methods and systems to diagnose depression
First Claim
1. A method comprising:
- receiving sensor data at a processor from one or more sensors of an external medical device, wherein at least one sensor is coupled to skin of a patient and configured to measure a parameter of the skin, wherein the sensor data corresponds to at least a first body parameter value for the patient and a second body parameter value for the patient;
determining, via the processor, a first depression-indicative value based on the first body parameter value and a second depression-indicative value based on the second body parameter value;
determining, via the processor, a first weight and a second weight;
determining, via the processor, a depression detection value as a function of, in part, the first weight applied to the first depression-indicative value and the second weight applied to the second depression-indicative value;
determining, via the processor, a depression state based at least in part on a comparison of the depression detection value to a first threshold value and a second threshold value different from the first threshold value, the first threshold value associated with an onset of a depression episode, the second threshold value associated with an offset of the depression episode;
adjusting, via the processor, the first weight based on a state of current physical activity of the patient relating to a current level of exercise of the patient; and
in response to determining that the depression state indicates depression onset, initiating closed-loop therapy by one or more electrodes.

Abstract
A method includes receiving sensor data at a processor from sensors of an external medical device. The sensor data corresponds to at least a first body parameter value for a patient and a second body parameter value for the patient. The method includes determining a first depression-indicative value based on the first body parameter value, a second depression-indicative value based on the second body parameter value, a depression detection value as a function of a first weight applied to the first depression-indicative value and a second weight applied to the second depression-indicative value, and a depression state based at least in part on a comparison of the depression detection value to one or more threshold values.

13. A system comprising:
-
a first sensor configured to provide first sensor data corresponding to a first body parameter value for a patient; a second sensor configured to provide second sensor data corresponding to a second body parameter value for the patient; and a processing unit configured to receive the first sensor data and the second sensor data, the processing unit including a processor configured to; determine a first depression-indicative value based on the first body parameter value and a second depression-indicative value based on the second body parameter value; determine a first weight and a second weight; determine a depression detection value as a function of, in part, the first weight applied to the first depression-indicative value and the second weight applied to the second depression-indicative value; determine a depression state based at least in part on a comparison of the depression detection value to a first threshold value and a second threshold value different from the first threshold value, the first threshold value associated with an onset of a depression episode, the second threshold value associated with an offset of the depression episode; adjust the first weight based on a state of current physical activity of the patient relating to a current level of exercise of the patient; and in response to determining that the depression state indicates depression onset, initiating closed-loop therapy by one or more electrodes. - View Dependent Claims (14, 15, 16, 17)
