Seizure disorder evaluation based on intracranial pressure and patient motion
First Claim
1. A method comprising:
- receiving, by one or more processors and from a pressure sensor, a pressure signal indicative intracranial pressure of a patient;
determining, with the one or more processors and based on the pressure signal, a trend in the intracranial pressure over time;
determining, with the one or more processors, a change in a seizure disorder of the patient based on the determined trend;
generating, with the one or more processors, an intracranial pressure indication in response to determining the change in the seizure disorder; and
controlling, with the one or more processors, a medical device to deliver therapy to the patient based on the determined change in the seizure disorder of the patient.

Abstract
Intracranial pressure of a patient may be monitored in order to evaluate a seizure disorder. In some examples, trends in the intracranial pressure over time may be monitored, e.g., to detect changes to the patient'"'"'s condition. In addition, in some examples, a seizure metric may be generated for a detected seizure based on sensed intracranial pressures. The seizure metric may indicate, for example, an average, median, or highest relative intracranial pressure value observed during a seizure, a percent change from a baseline value during the seizure, or the time for the intracranial pressure to return to a baseline state after the occurrence of a seizure. In addition to or instead of intracranial pressure, patient motion or posture may be monitored in order to assess the patient'"'"'s seizure disorder. For example, a seizure type or severity may be determined based on patient motion sensed during a seizure.
