A Study to Evaluate the SENSE Device's Ability to Detect TBI

The study population will consist of 3 mutually-exclusive sets of patients and subjects: * TBI patients with intracranial bleeding * TBI patients without intracranial bleeding * Control subjects with normal brain health. Research subjects ages 22 and older will be enrolled. All TBI patients must be monitored with the SENSE Device within 6 hours of a diagnostic head CT scan ordered by a treating clinician and within 24 hours of injury.
