SEIZURE DISORDER EVALUATION BASED ON INTRACRANIAL PRESSURE AND PATIENT MOTION
First Claim
1. A method comprising:
- delivering therapy to a patient to manage a seizure disorder;
sensing intracranial pressure of the patient;
determining a trend in the intracranial pressure over time; and
generating an intracranial pressure indication if a value of the intracranial pressure is greater than or equal to a threshold value.

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.
