The DETECT system: portable, reduced-length neuropsychological testing for mild traumatic brain injury via a novel immersive environment.

摘要

Undiagnosed mild traumatic brain injury (mTBI) often leads to poor patient management and significant morbidity. The lack of an efficient screening tool is especially apparent in the athletic setting, where repetitive injuries can lead to prolonged disability. We have developed the Display Enhanced Testing for Concussions and mTBI system (DETECT), in order to create a portable immersive environment that could eliminate visual and audio distractions. Neuropsychological tests sensitive to mTBI were modified for use with the system and allow rapid neurological assessment independent of the environment or trained personnel. We evaluated the immersive qualities of the DETECT system in 42 uninjured controls. The system was successful in blocking out external audiovisual stimuli. The neuropsychological test results obtained in a stimulus rich environment were equivalent to those obtained in a controlled quiet environment. The immersive environment, portability, and brevity of the DETECT system allow for real-time cognitive testing in situations previously deemed impractical or unavailable for mTBI patients.
