Seizure and movement monitoring
First Claim
1. An apparatus for detecting a seizure or other movement disorder of a patient, comprising:
- a sensor assembly comprising one or more sound sensors; and
a detector assembly adapted to receive an indication of sound detected by the one or more sound sensors, the detector assembly adapted to determine if the movement disorder is present based on the indication.

Abstract
An apparatus and method for monitoring movements of a patient is provided. If movements of the patient are detected to exceed predetermined thresholds, then a detector assembly determines that a seizure condition is present, and an alarm may be generated. In one arrangement, a sensor assembly includes one or more sound detectors to detect sound cause by patient movement. The detector assembly monitors the movement of the patient for determining if an abnormal movement or seizure condition is present. In another arrangement, an image sensor is used. A detector assembly monitors images produced by the image sensor to determine if the movements exceed predetermined thresholds. Other types of sensors can be used in other arrangements. The sensors can either be placed on a surface common to the patient or they can be attached to the patient.
