A Study to Test the SENSE Device in Patients With Intracranial Hemorrhage

Inclusion Criteria:

1. Male or female patients age 22 years and older

2. Diagnostic head CT scan within 24 hours of primary spontaneous ICH symptom onset

3. ICH >3mL and <90mL, as measured by the ABC method

4. Signed written informed consent by study subject or, if subject is unable, by
subject's next of kin or legal guardian

5. Willingness and ability to comply with schedule for study procedures

Exclusion Criteria:

1. Female patients who are pregnant or lactating

2. Patients with any history of seizure or seizure at stroke onset

3. Presence or history of any other condition or finding that, in the investigator's
opinion, makes the patient unsuitable as a candidate for the SENSE device monitoring
or study participation or may confound the outcome of the study

4. Any intraventricular hemorrhage on the diagnostic (pre-enrollment) CT with planned
placement of an intraventricular catheter

5. Secondary cause of ICH suspected (e.g., arteriovenous malformation, cavernoma,
aneurysm, hemorrhagic transformation ischemic stroke, venous sinus thrombosis, trauma)

6. Planned withdrawal of care within 24 hours of enrollment

7. Planned surgical evacuation within 24 hours of enrollment

8. Current participation in a medical or surgical interventional clinical trial

9. Presence of subdural, epidural or aneurysmal subarachnoid hemorrhage on diagnostic
scan

10. Planned continued use or prescribed use during the study of medications that, in the
investigator's best clinical judgment, are known or suspected to lower the seizure
threshold

11. Planned continued use of medications that, in the investigator's best clinical
judgment, could increase the chances for subsequent uncontrolled hemorrhage

12. Planned or current use of continuous EEG monitoring
