Benefits of technology

[0017]Yet another aspect of the invention provides a method of automatically recording clinical manifestation data from a patient. In some embodiments, the method includes the steps of monitoring neurological data from a patient; estimating the patient's brain state based on the monitored neurological data; determining a change in the patient's brain state; and automatically recording clinical manifestation data from the patient using a device worn or held by the patient.
[0018]In some embodiments, clinical manifestation data is recorded when one or more specified changes in brain state occurs. In some emb...

Embodiment Construction

[0028]Described herein are systems and methods for determining if an observable clinical manifestation of a seizure is associated with the system's detection of a seizure or the system's determination of a patient's increased propensity for having a seizure (also referred to herein as “seizure prediction”). The system generally monitors a physiological signal (e.g., neurological data such as an electroencephalogram, or EEG) from the patient to detect the occurrence of a seizure and / or to estimate the patient's propensity for having a seizure. The correlation between observable clinical manifestation data of a seizure and the system's detection of a seizure and / or estimation of the patient's propensity for the seizure can assist in determining if the system is accurately estimating the propensity for having a seizure (or the detection of the seizure). The occurrence of an observable clinical manifestation of a seizure without the system's estimation of an increased propensity for...

Abstract

A method of comparing a patient's neurological data to data that is indicative of the patient's clinical manifestation of a seizure. In some embodiments, the method includes the steps of monitoring neurological data from a patient indicative of the patient's propensity for having a seizure; automatically recording clinical manifestation data from the patient that may be indicative of the occurrence of a clinical seizure; and analyzing the automatically recorded clinical manifestation data and the monitored neurological data to determine if one of the clinical manifestation data and the neurological data indicates the occurrence of a seizure while the other does not. Systems are described including a monitoring device having a communication assembly for receiving neurological data transmitted external to a patient from a transmitter implanted in a patient; a processor that processes the neurological data to estimate the patient's brain state; and an assembly for automatically recording clinical manifestation data in response to a brain state estimate by the processor.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 017,501, filed December 28, 2007, which is incorporated by reference as if fully set forth herein.INCORPORATION BY REFERENCE[0002]All publications, patents, and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference.BACKGROUND OF THE INVENTION[0003]Systems have been proposed that can monitor neurological data from a patient and use the data to detect a neurological event, such as the onset of an epileptic seizure. In such systems it may be desirable to additionally monitor a patient's notes and seizure logs to derive or change device settings.[0004]Seizure logs, both written and electronic, have been used to monitor patient's seizure activity. However, conventional electronic seizure...
