ANXIETY DISORDER MONITORING
First Claim
1. A method comprising:
- detecting, with a processor, an anxiety episode of a patient based on a physiological parameter of the patient; and
determining, with the processor, whether the anxiety episode is an anxiety event attributable to an anxiety disorder of the patient based on a signal indicative of patient activity.

Abstract
An anxiety episode may be identified as being an anxiety event that is attributable to an anxiety disorder of a patient based on the patient activity associated with the anxiety episode. The patient activity may include, for example, patient motion, patient posture or voice activity. Detection of the activity component during an anxiety episode can help distinguish between a general anxiety state and an anxiety event that differs from the general anxiety state. Examples of anxiety events include, for example, an occurrence of a compulsion or a panic attack. The detected anxiety events can be used to evaluate an anxiety disorder of a patient, evaluate therapy programs implemented by a medical device to treat the anxiety disorder, or control therapy delivery. In some examples, a mood state transition is detected based on patient activity information and therapy delivery is controlled based on the detection of the mood state transition.

18. A method comprising:
-
receiving a first physiological signal indicative of an anxiety state of a patient; receiving a second signal generated by a sensor, wherein the second signal is indicative of at least one of motion, posture state or voice activity of the patient; and identifying, with a processor, an occurrence of an anxiety event during the anxiety state based on the first and second signals. - View Dependent Claims (19, 20, 21)

22. A system comprising:
-
a first sensing module that generates a first signal indicative of physiological parameter of a patient; a second sensing module that generates a second signal indicative of activity of the patient; and a processor that detects an anxiety episode of the patient based on the first signal and determines whether the anxiety episode is an anxiety event attributable to an anxiety disorder of the patient based on the second signal. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
