CLUSTERING OF RECORDED PATIENT NEUROLOGICAL ACTIVITY TO DETERMINE LENGTH OF A NEUROLOGICAL EVENT
First Claim
1. A method for updating a therapy parameter that is associated with a treatment therapy by a medical device during a neurological event of a nervous system disorder, the neurological event corresponding to at least one detection cluster, the method comprising:
- (a) determining if the neurological event of the nervous system disorder is occurring; and
(b) in response to step (a), adjusting the therapy parameter for each mth successive group of applications of the treatment therapy during a first detected cluster, wherein m is a first positive integer greater than one and wherein each group of applications comprises at least one application of the treatment therapy.

Abstract
Apparatus and method detect a detection cluster that is associated with a neurological event, such as a seizure, of a nervous system disorder and update therapy parameters that are associated with a treatment therapy. The occurrence of the detection cluster is detected when the maximal ratio exceeds an intensity threshold. If the maximal ratio drops below the intensity threshold for a time interval that is less than a time threshold and subsequently rises above the intensity threshold, the subsequent time duration is considered as being associated with the detection cluster rather than being associated with a different detection cluster. Consequently, treatment of the nervous system disorder during the corresponding time period is in accordance with one detection cluster. Treatment therapy may be provided by providing electrical stimulation, drug infusion or a combination. Therapy parameters may be updated for each mth successive group of applications of the treatment therapy or for each nth detection cluster.

21. A medical device that updates a therapy parameter that is associated with a treatment therapy during a neurological event of a nervous system disorder, the neurological event corresponding to at least one detection cluster, the medical device comprising:
-
a configuration of monitoring elements;
a delivery module that delivers the treatment therapy to a patient of the nervous system disorder; and
a processor that is coupled to the configuration of monitoring elements, the processor configured to perform the steps of;
(a) determining if the neurological event of the nervous system disorder is occurring; and
(b) in response to step (a), adjusting the therapy parameter for each mth successive group of applications of the treatment therapy during a first detected cluster, wherein m is a first positive integer greater than one and wherein each group comprises at least one application. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
